WOCA Softwood Lye Product 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.

*Note -When Softwood Lye is used on spruce, the wood may assume a greenish color. The greenish color will disappear in the course of time.

How To Apply WOCA Softwood Lye

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.
