The unfinished woodwork must be clean, dry and finely sanded (grit 100-120) before applying the lye. Wear suitable acid proof protective clothing, gloves and eye goggles for protection. On vertically mounted woodwork, apply from bottom to top.
Always remember to test on a less visible spot to check the compatibility of the surface with the product.
1. Shake the container well and pour the Lye into a plastic bucket. It is important that no pigments are left in the container. Stir regularly during the application to prevent the pigments from settling to the bottom.
2. Apply an even coat of the lye with the WOCA Applicator, a nylon brush or roller lengthwise along the grain. Apply at least 1 container of lye per 250 sq.ft. Leave wood to dry for approx. 3-4 hours at 68°F.
3. Clean the floor with WOCA Intensive Wood Cleaner. Leave the floor to dry for at least 8 hours. The floor must be completely dry.
4. De-nib standing fibers and remove excess pigments with a medium e.g. green or maroon, sanding polishing pad. Remove the sanding dust with a vacuum cleaner.
5. Finish the wood surface with a WOCA oil.
Depending on the amount of moisture and tannin in the oak, the color may vary. Sapwood does not change to a dark color.
