Coatings for Interior Woods - Polycoat/Lamination - Hi Gloss, Wear Resistant, Water Resistant finishes using Paraffinated Polyester

Teak Veneer coated with Parafinated Clear Polyester.
To get a high gloss, water and wear resistant finish for your interior woods, look no further than Paraffinated Polyester. Paraffinated Polyester popularly known as Polycoat/Lamination is available in transparent and opaque finishes.

The clear finish is truly high gloss and extremely clear (100% colourless), making the wood grains really stand out, thus enhancing the beauty of the wood. 
The opaque finish gives unmatched gloss. The scratch resistance and gloss give this system an edge above the rest.

Materials Required

. Spray Gun and compressor.
. Rubbing compound.
. Orbital Buffing machine and Wool Pad.
. NC Thinner for cleaning.

Application

. Sand the wood surface using 80-100 grit aloxite dry sanding paper. (For Veneers, use 120-150 grit papers.)
. 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!!

  2. In case an orbital machine is not available, grinding machines can be used at low rpms.
    Rubbing using waste is also possible but very time consuming.
