By making wood surfaces water resistant, we can achieve dimensional stability and protection against warping and decay. Additionally, treated surfaces exhibit oil repellent properties - preventing oil from penetrating the wood surfaces. Application of NSW does not induce any visible change on the surface applied and does not block the pores (no pore sealing like traditional varnish or wood stain). This, the breathing ability of the natural wood surface is preserved.DIRECTIONS OF USAGE:1) Ensure dry and clean surface2) Spray Nano-star Solution over floor tilings evenly (NO DILUTION IS REQUIRED!)3) Even out the solution on Wood Surface using a floor brush4) Reapply within 3 hours5) Allow curing time of 8-24hours for maximum effect
