WOCA Softwood Lye Details

WOCA Softwood Lye is used for lye priming of unfinished or freshly sanded interior woodwork such as floors, stairs, furniture, and panels. The priming prevents the wood from yellowing and enhances the natural grain of the wood producing a white wash finish. WOCA Softwood Lye may be used for all types of soft wood such as pine, spruce, and pitch-pine. When Softwood Lye is used on larch wood, an antique grey/brownish finish is created. Softwood Lye can not be used on hardwood. The final color will first be achieved after 1-2 months. Results vary.

*Note -Use of Softwood Lye may cause a greenish color initially which will disappear in the course of time and fade to grey.

Wear suitable acid proof protective clothing, gloves and eye goggles for protection.
  1. The unfinished woodwork must be sanded finely (grit 100-120) and it must be completely clean and dry before application of the lye.
  2. Shake the container. Pour the lye into a plastic bucket and stir regularly to get a uniform result.
  3. Apply the lye undiluted with the WOCA Applicator, a nylon brush or roller in an even coat on the floor lengthwise. Apply at least 1 liter of lye to 110 square feet of wood. On vertically mounted woodwork, apply from bottom to top.
  4. After a drying time of 8 hours at 68˚F (the wood must be completely dry), de-nib standing fibers with a fine sanding polishing pad (green or maroon) before the final basic treatment. Subsequently, vacuum the floor.
  5. Finish the floor with Diamond Oil or another WOCA oil or treat with Basic Soap or Natural Soap, White.
  6. Clean tools in water after use.
