Thirothane Industriel Urethane Varnish Français
THIROTHANE is an oil based polyurethane varnish extremely durable and highly resistant against abrasion, water, alcohol and commun household products. Offered in gloss finish it can be used over wood floors in interior applications.
Surface Preparation
Sand completely along the wood grain with a coarse sandpaper (80) then sand the surface with a finer sandpaper (120) until a smooth and uniform surface is obtained. Remove completely dust or any deleterious substances and debris. Sand dust resulting must be removed with a vacuum cleaner and followed by a final cleaning with a solvant humid pad to eliminate any trace of dust. We recommend the THIROCO SCELLEUR 100 as primer on wood floors.
Temperature and relative humidity are critical factors for an appropriate drying. For the application and curing of THIROTHANE, temperature should be more than 10ºC, however best conditions are 25°C and 50% of relative humidity. Pour a small quantity directly on the floor or in a paint pan and spread the finish evenly and uniformly. Use a pure silk bristle brush or a pad applicator. Allow a minimum of 24 to 30 hours between coats according to ambient conditions. It is necessary to sand lightly the surface with a sandpaper of 180 to 220 along the wood grain between coats and taking care of removing any dust coming from sanding. We recommend to apply 2 coats of THIROTHANE if the SCELLEUR 100 is used or 3 coats if SCELLEUR 100 is not used.
