Why use synthetic hair paint brushes ?

Paint brushes can be made from Natural or Synthetic hair. Natural hair comes from animals such as squirrels, sable, hogs etc. Synthetic hair is made from filaments of polymers such as polyester or nylon. Natural hair harvesting leads to animal cruelty and killing of animals such as squirrels. With quality synthetic hair available, there is no reason for use of natural hair. Synthetic hair is more durable, easy to maintain and brushes made from synthetic hair can be manufactured in a variety of shapes and cuts. The synthetic hair can be processed chemically to change its properties such as stiffness, abrosption and finish to make it suitable for a variety of paints like water, acrylic, oil etc.

Some manufacturers produce filaments specifically for making brushes having their own polymer formulae. The company Dupont manufatures bristles under the brands Tynex®, Orel®, Kulex®. These bristles have unique properties that have been built into the filaments such as abrasives to give better grip on the surface being painted, more stiffness where needed and hog hair replacement bristles for ecomonical brushes.These have revolutionized the painting industry where the quality of the paint was ever increasing, but the available brushes were not upto to the mark. But with the advent of synthetic bristles, brushes have also improved by leaps and bounds.

Brushes can now be manufactured keeping the needs of the professional painter in mind. Economical brushes for rough work, finish brushes for top class finishes and many more. Not only paint brushes, but artist brushes and makeup brushes have also benefitted from synthetic bristles. So, be kind to animals and use synthetic hair brushes.

How to Stain Wood

Wood by itself is a thing of beauty. But in many situations, we need to dress up wood to meet the aesthetic and practical requirements of its design and environment of use. Staining wood is the first step in dressing it up. Make pine look like teak wood or wood look like green bamboo, there are innovative ways to achieve striking results.

There are many schools of practice on how to stain wood. Let us look at some traditional and modern methods each have their own pros n cons.

Traditionally in India, wood is stained using powder pigments. These powder pigments are often chalk powder based and it involves mixing of raw pigments such raw sienna, burnt sienna, burnt umber etc with porbander chalk powder. These are then mixed with dispensing media such as French polish, sanding sealers or solvents such as methylated spirit and applied on the wood using a cotton rag. This method hides most imperfections on the wood and is suitable to any type and colour of wood. Unfortunately, along with hiding the imperfections, it also hides the natural grain of the wood giving it a pasty appearance. This method is suitable only for hand polishing or French polish. The stain thus obtained cannot be coated over by melamine or PU as the solvents used to dispense the pigment are not compatible with these polymer coatings. More over, if coated over, the solvents used to stain the wood begin to evaporate and cause the polymer film to break and eventually peel off.

There is another method to stain wood using powder pigments that does not involve solvents. Pure pigments such as the oxides of iron available in yellow, red and black hues can be mixed with water and applied to stain the wood. The intensity of the stains thus created can be controlled by changing the dilution of the pigment. In such a method, a pre stain coating is recommended as the stain can turn out patchy when applied using a rag or a roller. Application of the water based stain thus created causes the wood grain to get slightly raised lending a rough surface. Pre wetting and sanding of the raised grain is recommended to avoid this problem. This method is compatible with all types of wood coatings. Due to the absence of heavy powder usage, the wood grain appears enhanced and clear. The only drawback to this method is control of the stain intensity. Different batches of the stain may turn out different if the proportions are not the same.

The method recommended by most experienced wood workers is staining using manufactured wood stains. These stains are available off the shelf in a variety of colours. They are available in water

based and solvent based varieties. The solvent based variety carries a fast evaporating solvent which flashes off in about 2-3 hours and is compatible with all types of wood coatings. The water based variety dries off slower but provides a more even finish. The water based stain also needs to be applied after pre wetting and sanding for a smooth finish. Both stains can be applied as is or after dilution with an appropriate solvent. To get an even stain, it is recommended to apply a coat of pre-stain before staining the wood.

Application of Stains

The first step to applying wood stain is applying the pre-stain.

What is pre-stain?
Pre stain is a coating used before staining of wood. It partially closes the grain of the wood and makes it less absorbent. The stain applied after pre stain spreads more evenly.

Is pre-stain available in India?
Pre-stain is not available readily off the shelf in India, but one can easily create a pre-stain using the following method:
Purchase a can of the appropriate sealer - it can be water based or solvent based. Some varieties of sealer are: Water based PU sealer, solvent based PU sealer, Melamine sealer, and for hand polish -

sanding sealer.
Thin it 100% using the appropriate solvent. For water based sealers, use water and for solvent based sealers such as PU Sealers, use PU thinner.
This is your pre-stain.
Apply it along the grains using a cotton rag or a roller.
After the application of the pre-stain, the wood stain can be applied using a clean cotton rag or a roller along the grains. More than one coat of stain can be applied to get a greater colour depth, but remember, more stain means lesser natural wood grain.
This completes the wood stain.

To complete the wood finish, wood sealer must be applied over the stain first. Never sand the wood stain. Sanding must be done only after application of the sealer. The sealer now applied must be applied as a sealer coat and not as a pre-stain i.e. the sealer must now be thicker in consistency and used with the intention of sealing the wood completely. More than one coat of sealer must be applied, sanding with emery grit 180 between coats and with emery grit 320 on the final coat. The wood can then be finished using the top coat.

Hope this helps you stain your wood to perfection.

Melamine vs PU

Two of the most popular transparent/natural wood finishes are melamine and PU(Polyurethane). Melamine and PU are both synthetic hydrocarbon polymers which form a film over the wood surface that is coated, thus laminating it. The purpose of lamination is to preserve the wood by not allowing the moisture of the wood to escape, preventing it from damage from the elements and protecting it from wear and tear from use. Both finishes enhance the aesthetics of the wood by allowing light to refract inside the transparent layer formed by them. Both the finishes have a similar application procedure by spray. So, what is the difference between the two?

The main difference is in the life of the coatings and its resistance to the elements.

PU Finished Door

Melamine was a great improvement over wood polish as a transparent wood finish when it was introduced in the Indian market in the late 80s and the 90s and is popular to date due to its economy. But melamine has its limitations. The film formed by melamine is only moderately resistant to water. It deteriorates when exposed to sunlight. The film easily yellows and looses lustre. The film begins to crack at the wood joints over time.

With the advent of polyurethane (PU) in the late 90s, most of the shortcomings of melamine were covered. PU forms a tougher film than melamine. It is more scratch resistant. It is flexible and does not crack with the movement of the wood joints. It is UV resistant and can be used on woods that are used in exteriors, such as entrance doors and windows. It does not yellow easily and gives a high lustre. The lustre is also retained longer due to its UV resistance.

PU gives clear advantages over melamine as the application procedure remains the same for both and there is no new skill required to apply PU. Thus the work involved takes the same time and effort on part of the applicator.

Consider wood finishing as a one time investment as reworking of wood finishes takes up lot of resources, skill, time and money. Go for the best coating for your expensive teak or other exotic woods as it will not only preserve the wood but also enhance its aesthetics.

Some things to note when applying Melamine or PU

Melamine or melamatt polish as it is popularly known among the painting contractors is usually sprayed over French/hand polished surfaces, which is not the intended procedure of application.

A study of melamine shows that for all intents and purposes, as in PU, was not originally developed as a wood coating. It is a product of innovation and adaptation that these products are used as wood coatings. The adaptation requires a specific application procedure for the product to perform as a wood coating. These application procedures are grossly ignored by applicators and contractors.

A damaged French Polished door

Applicators apply generous coats of French polish and NC Based Sanding sealers as a preparation for the final coating by melamine or PU. They do this as their skill set for colour matching of wood is based on French polish techniques.

The melamine and PU films often fail as the solvents in the French polish and NC sealers are not compatible with solvents used in PU and melamine coatings. Also, the solvents in the French polish applied under transparent coatings are exposed to light and begin to evaporate and cause blisters in the polymer film formed over it.

It is thus highly recommended that application of French polish be avoided when any such coatings are applied. Wood coated by French polish has its own charm and should not be over coated by polymer coatings.

There are much simpler and compatible colour matching techniques for melamine and PU using wood stains, which we shall discuss in another post.

What is the Difference Between Duco NC Lacquer and PU?

Duco is a brand owned by Akzo Nobel (formerly ICI) and represents a Nitro Cellulose (NC) Based lacquer available in transparent and opaques. NC lacquers were widely used in the automobile industry to finish vehicle bodies to get a tough weather resistant, glossy film with performance far superior to the then prevalent enamels. But there were a few drawbacks to NC. NC Lacquers are highly viscous and take large amounts of thinner to thin to a sprayable consistency. Nitrocellulose on exposure to sunlight deteriorates, loses gloss and turns yellow. It is also notorious to apply on edges and often begin to peel off at the edges. The NC paints needed to be periodically buffed to remove the yellowed top layer. This leads to reduction of the paint film thickness. NC lacquers are also sensitive to ambient temperature and humidity during application. The temperature and humidity are known to adversely affect the gloss of the finish.

With the advent of Polyurethane coatings, NC began losing popularity as the preferred choice for vehicle body painting. PU as polyurethane is popularly known, has far better technical specifications to NC. PU is colour fast in sunlight and does not deteriorate even on prolonged exposure. PU forms a tougher film than NC due to extensive cross-linking introduced in the polymer. PU does not chip or peel off like NC. No buffing is required to maintain colour and gloss. PU can also be applied in a wide range of atmospheric conditions as compared to NC. PU is also easier to tint and match than NC due to the clarity of its binder and lower viscosity. PU can also be tinted to metallic shades. PU is also available in matt finishes.

Both NC and PU are used to coat wood and metal. These materials are also in wide use in home decor. PU is now the leading coating in the automotive industry and is fast gaining popularity in the decorative segment as well.

With green standards fast becoming the norm, PU is also available in water based variants that can be used to coat wood. They have a comparable performance to Solvent based PUs and are much easier to apply. They don't require elaborate spray equipment and also do not pose a health hazard as they can be brushed on.

What is Duco Paint? How is it applied?

Duco is a brand marketed by Imperial Chemical Industries (ICI now merged with Akzo Nobel) under which it sells its popular Automotive paints. The Duco brand represents a range of products meant for auto painting and refinishing. The topcoat or the finish coat available under the brand Duco is a Nitro Cellulose (NC) Lacquer. Due to its wide spread use and popularity, the name "Duco" has been genericized to refer to Nitro Cellulose (NC) Lacquers.

Duco was vastly popular as an automotive finish before the advent of Polyurethane paints. Now a days Duco has found a new life as a high quality finish for interiors and other architectural projects. 

NC Lacquers typically are a clear or coloured wood/metal finish that dry by solvent evaporation and produce a hard, durable finish.  (Read more about Lacquers in general here)

Duco being an NC Lacquer has the following properties :

• Fast Drying
• High Solid content 
• Excellent Water Barrier
• Excellent Self Leveling properties
• Takes very well to buffing to give a high sheen 
• Smooth and Hard finish

 Areas of Application :

• Automobile body
• Plywood and MDF
• Sheet Metal
• MS angles and flats
• Architectural and Industrial metal structures

The different surfaces require different preparations. Let us look at the application methods for each of the surfaces mentioned above.


Application method for Sheet Metal and MS Structures :
Materials Required

• Compressor capable of delivering 30-40 psi pressure consistently.
• A good quality spray gun - preferably HVLP type.
• Safety Equipment - Mask, Glasses, Gloves and Overalls.
• Degreaser solvent
• Degreaser Cloth
• Duco Oil Primer / MRF Etch Primer
• Tak Cloths - to remove sanding dust.
• Duco Primer Surfacer - Grey / White - depending on the top coat colour you choose. For Lighter coloured top coats, use Primer Surfacer White and for darker topcoats, use Primer Surfacer Grey.
• Duco Soft Cut Putty 
• Water Emery (Latex paper backed) of grits 220 and 320
• Sanding block
• Duco NC Lacquer
• Duco Thinner
• Rubbing Compund - 3M 1Step is highly recommended.
• Cotton Waste

Application

• Scrap off any loose particles, dirt and old paint from the metal surface to bare metal.
• If the base metal is galvanized, an etch primer is recommended.
• For bare sheet metal, a coat of Duco Oil Primer thinned with a General Purpose thinner in the ratio 5:1 must be applied and allowed to dry overnight. The Duco Oil Primer has excellent adhesion, corrosion resistance and is air drying.
• Apply 2 coats of Duco Primer Surfacer (PS) thinned with Duco Thinner in the ratio 1:1.5 with a flash off interval of 15 minutes between coats.
• Rectify any minor dents and scratches using Duco Soft Cut Putty and a putty knife.
• Wet sand with water emery of grit 220 followed by 320 to level any imperfections.
• Apply a coat of Primer Surfacer on the puttied areas.
• Choose a colour!
• Apply 2 coats of Duco NC Lacquer thinned with Duco Thinner in the ratio 1:2 of the selected colour. Allow flash off interval of 15 minutes between coats.
• Leave to dry overnight.
• Wet sand flat (remove gloss) carefully with emery grits 600/800and apply one mist coat thinned 1:3 with Duco Thinner.
• Allow to dry overnight and polish the surface using 3M 1Step Rubbing compound. 
• For a higher gloss polish use 3M Premium Liquid Wax.

Application for wood and MDF surfaces follows the same procedure as above except for priming using Duco Oil Primer. The Duco Primer Surfacer is applied directly onto the wooden surface.

The finish thus obtained is long lasting and durable.

Duco has the following limitations :

• Requires elaborate equipment to apply - compressor and spray guns are the basic requirements.
• Colour stability on exposure to sunlight is average - easily yellows.
• Attention to surface preparation is required before application - needs a skilled workman.
• Duco is sensitive to the atmospheric conditions during application - A change in temperature can affect the finish.
• Being solvent based, it is not environmentally friendly and precautions must be taken against the health hazards during application. At minimum a respirator mask, gloves and glasses are required. Body overalls are highly recommended. An exhaust system must be in place to extract the solvent flashing off the surface.

Water Based PU Finishes for Wood

We all need a cleaner environment and water based variants in paints are definitely a step toward this. Water based products such as water based polyurethane for wood are eco-friendly in that they have very low percentages of volatile organic compounds. Not only are these products environmentally responsible, projects can also be turned around faster. Water based systems have faster drying times and are easier to apply - They need not be sprayed. No solvents required, only water is required for thinning and cleaning - thus posing a very low health hazard to applicators. Polyurethane has the property of having good abrasion resistance, good UV stability and creates an impermeable water barrier. Too good to be true? Well the future of paints is here - water based polyurethane coatings for wood. Excellent for outdoor wood and indoor furniture.

The finish of these products is pleasing to the eye and the matt finish is soft to the touch. It gives the wood a natural, well finished and rounded look. 

 Let us look at the application procedure for Water Based Polyurethane products :

Materials

. Random Orbital Sander
. Velcro Discs for Orbital Sanders 5" or 6" - Open coated type - Grits 120, 150, 180, 220
. Sheets for Hand Sanding - Open coated type - Grits 120, 150, 180, 220
. Scotch Brite Hand Pads or Steel Wool.
. Brush 2", 3"
. Felt Roller 4"
. Putty Knives 2", 3", 4"
. Dent Filler
. Wood Filler
. Water Based Polyurethane Base Coat
. Water Based Polyurethane Top Coat - Matt or Glossy.
. Clean potable water.

Application
. Sand the veneer/wood along the grain with papers of grit 120/150. An orbital sanding machine can also be used with the same grits.
. For woods with carving or grooves, Scotch Brite Handpads or Steel Wool must be used for sanding.
. Brush on a coat of wood preservative along the grains for exterior woods and allow to dry for 3-4 hours.
. If the wood has been polished previously using traditional Spirit based polish, apply a coat of wood filler using a putty knife or muslin cloth after sanding and wood preservative application. Allow to dry for 3-4 hours.
. Using a dent filler, fill major dents and imperfections using a putty knife.
. Apply the 1st coat of interior/exterior sealer by spray, brush or roller depending on the depth of the grains, along the grain. For 2K systems, the hardner has to be mixed in the given proportion - Be sure to allow for sufficient maturation time and to use the material within the given pot life. Dilution of up to 10% is allowed using clean water.
. Allow to dry for 4-5 hours.
. Sand the 1st coat using 180/220 grit sand paper. A white powder as a result of sanding is an indication of successful application and curing of sealer.
. Apply a 2nd coat of sealer and repeat the process followed for the 1st coat.
. Once sealer coats are completed, apply 1st coat of topcoat matt or glossy by spray or roller. For 2K systems, the same precautions apply. Dilution of upto 10% is allowed using clean water.
. Apply a 2nd top coat after 5-6 hours.
. Buffing operations can be taken up for glossy topcoats after about 12 hours and within 4 days from the time of application of the 2nd topcoat.

Value of Wood Finishes

Wood is used for its strength, ease of use and aesthetics. Two conditions influence the life of wood: weathering and decay. 

Weathering 

Weathering is erosion from sun, wind and debris, and moisture. If wood is not protected by paint or stain, the weathering process removes about ¼ inch of wood per century from softwoods on vertical exposures; even more wood is eroded in severe exposures.

The first step to prevent weathering is to block the sunlight. Finishes differ in their ability to protect wood from the sun. Paints can block sunlight completely, but they can trap moisture and encourage decay. Semitransparent stains are the next best way to block sunlight, followed by water-repellent preservatives, especially those that contain ultraviolet (UV) light inhibitors.

Decay

The other major service-life concern is decay (rot). Because outdoor wood is exposed to moisture, it is subject to decay. Decay, or rot, occurs due to the growth of specific fungi which feed on the fibres in the wood. Exposure to fungal spores that develop into fungi cannot be avoided as the spores are found everywhere. These spores will germinate and grow if the following four requirements are present:

. oxygen
. mild temperatures
. moisture, and
. suitable food (the wood).

For exposed wood structures, control over oxygen and temperature is not possible. However, control over moisture is possible. Eliminating this requirement will eliminate the potential for fungal growth and decay.

Protective Coatings 

One of the methods to eliminate moisture and ensure long life of wooden structures is to use protective coatings. Protective coatings for wood are used

. to enhance appearance

. to minimize ultraviolet degradation, and
. to protect against moisture exposure and fungal degradation.

Wood used in exterior applications needs to be protected and maintained periodically for a long life. As a general rule, recoating should be done when the previous finish is just beginning to show signs of aging, and before it loses its ability to protect the component.

A list of popularly used coatings for wood is below, graded by quality from low to high:

. Enamels - Solvent based

. Enamels - Water based

. Alkyd based coatings 

. Nitro-Cellulose Lacquers

. Epoxy Coatings

. Poly Urethane coatings(PU)

. Polyester coatings
 
Below is a table comparing a few of the wood finishes.

Why PU over other wood finishes.

Using quality fasteners

For any wooden structure to last, the joints have to be strong. Wood at joints are held in place using Fasteners. A good fastener not only guarantees strong and long lasting joints but also faster turn around times on projects. Fasteners such as 

. stainless steel nails 

. stainless steel screws and  

. galvanized nails 

 are recommended. 

These add only a fractional cost to a project when compared to lower quality products but turn out to be real money savers in the long term.

. Stir the two parts of the Epoxy Isolant first in their individual containers and then mix the two together in an empty container. For a clear finish, apply Epoxy Isolant base by wiping with a soft muslin cloth on to the entire wood surface. For opaque finishes, apply Epoxy Isolant base by spray (Nozzle 1.5mm, 28-30 PSI).
. Allow the base to dry. Drying time of about 2-3 hours.
. The top coat is prepared for spray by mixing the polyester base, accelerator and hardner in the ratio of 100:2:2. Add the entire quantity of the cobalt accelerator (blue) to the base in the given ratio. The hardner is added only when the material is about to be sprayed. For proportioning appropriate measurement cups and syringes are recommended. The proportion must be maintained meticulously. Keep the spray nozzle width at about 2.5-3mm at 28-30 PSI.
. Pour the prepared material into the gun cup.
. Spray 8 to 10 coats of the topcoat in wet on wet condition with 5 minute intervals between coats.
. Wash the spray gun thoroughly and immediately after use using an NC thinner.
. Allow the topcoat to cure for 24 to 36 hrs to attain full hardness.
. Sand the paraffin using no-fill paper of grits 220, 320 and 400 to remove the paraffin coat entirely and get an even surface.
. Now wet sand the topcoat progressively with grits 600, 800, 1000, 1200, 1500, 2000 wet emery papers to remove all scratches and imperfections.
. The thus prepared surface should now be buffed using a rubbing compound and a wool pad mounted on an orbital buffing machine. The RPM of the orbital buffing machine must be low (below 1000) to get a high gloss.


Your furniture and doors now stand a class apart!!

How to protect and finish Interior and Exterior Woods with PU Coatings

Polyurethane(PU) is an excellent choice when you want to protect expensive Teak, Walnut, Wenge or other exotic woods from the elements. It has good UV resistance and excellent sealing properties against water, moisture and humidity. PU retains it finish over prolonged exposures to UV. PU Matt and Glossy finishes for wood.
Let us see how to apply PU coatings to wood.

African Wenge treated with PU Sealer and PU Glossy top coat.

Materials Required

. 2 Part Solvent Based PU Sealer.
. 2 Part Solvent Based PU Top coat - Matt or Glossy.
. Wood stains, if required.
. PU thinner.
. Compressor for spray.
. Paint Gun. (250ml or 500ml Cup is sufficient)
. Dry Sanding Aloxite Paper 80, 120, 180
. Wet Sanding Paper 320, 600,  800, 1000
. Cotton Waste.
. Filter Cloth.
. Masking Tape.
. Face Mask to prevent inhalation of spray.
. Gloves and eye glasses.

Application

. Prepare the wood by dry sanding with emery grit 80 to smooth the grains and undulations on the surface. Sanding should be done along the grain.
. Once major imperfections are removed, dry sand with emery grit 120 to get a smoother finish.
. Switch on the compressor to get the required PSI. (Here is an excellent article on how to spray paint using a paint gun and a compressor). Connect the spray gun to the compressor.
. Wipe clean the surface to be sprayed using a dry cotton cloth.
. The Sealer can be tinted or transparent depending on the desired final finish.

. Pre-preparation For Porous woods

. Mix the Sealer base and hardner in the given proportion without adding thinner. (All Mixes must be consumed within the prescribed pot life)
. With a muslin/cotton cloth apply sealer mix along the grain on to the entire surface maintaining uniform thickness.
. After the sealer has completely cured and hardened, sand the flat surfaces with 180 grit free cut/ open cut emery using an emery trowel. For uneven, round, carved etc surfaces, 3M hand pads/scotch brite hand pads equivalent to 180 grit can be used. All excess sealer must be sanded and removed completely to get a smooth uniform surface. Wipe the thus surface clean.
. The rest of the procedure is the same as for regular woods.

. For Regular woods

. Mix Sealer base and hardner along with 10% - 15% thinner. Pour mix into the spray gun.

. Spray the sealer onto the surface.

. Clean the spray gun.

. Wait for sealer to cure and harden.

. Sand with emery/hand pad grit 600. Wipe clean.

. Additional coats of sealer can be applied for a smoother finish.

. Mix Top coat (Matt or Glossy or Mix a of the two) base and hardner in the given proportion along with 10% - 15% thinner. Pour mix into the spray gun.

. Spray mix onto the entire surface. 

. Wait for top coat to cure and harden. 

. Sand with emery/hand pad grit 800. Wipe clean.

. Spray a second coat of the top coat.

. Wait for top coat to cure and harden.

. In case of gloss finish, additional top coats can be added by sanding with 1000 grit emery between coats.

. Gloss top coats can be further buffed using rubbing compounds to get a high gloss finish.

Notes

. If the wood is previously coated, remove the coating by scraping and a paint remover. Ensure the paint remover has completely evaporated before coating. 
. Ensure exterior woods are coated from all sides.

A Tough and beautiful finish is thus achieved ... and the wood grains stand out!!!
