There are two different types of polyurethane polishes, water-based and solvent-based. Both leave a strong protective coat on the wood. PU polish is comparatively expensive compared to Melamine based polish and carpenters prefer this polish as it can give superior shining in shorter time using less labour. The PU polish is available in multiple stains that help getting the desired shade of wood. You can choose from the shades of teak, mahogany finishing, natural veneer style or other shades available. For exterior and interior application, there are different wood stains in the market so make sure you pick the right stain for the application.
A variety of raw materials are used to produce polyurethanes. These include monomers, prepolymers, stabilizers which protect the integrity of the polymer, and colorants.
Wood filler/ filling materials, staining, sealing material and top coat as per finish required such as Varnish, Spirit or French polish, Melamine based finish and tools for polishing.
To apply melamine based polish on a surface, remove all dust and dirt from it.
PU Polish on wood work and furniture protects the wood from all weather.
Polish finish is weak against moisture. Wet weather reduces the life of polish finish.
Allow 4-6 hours total, stretched to allow drying time for the finish.
Two coats are recommended at an interval of 6-8 hours between the two coats.
