Softwood Lye

Proff Soft Wood Lye may be used on all kind of soft wood such as pine, pitch-pine and spruce. It prevents soft wood from going yellow and ensures that the wood remains light. After lye application, the woodwork needs Proff Proff Oil or Proff Wood Floor Soap treatment for protection. It is important that the yellowing process has not already started before application of the lye. Wall and ceiling panels should be lye treated before mounting due to corrosive material.

Work Instruction:

1. The surface of the wood must be completely dry and free from dirt and grease. The surface should be freshly sanded before application.

2. Shake the bottle well and pour material into plastic bucket and stir well so that all pigments and lime are evenly distributed in material.

3. Use goggles and gloves for protection. Lye is corrosive.

4. Apply lye in an even layer lengthwise of the boards using an acid proof brush.

5. Stir material regularly during application.

6. Use 1 liter of lye to 10m2 of floor or panel.

7. Clean tools with water.

8. After basic priming with lye, a finishing treatment is required. Wait for 6 hours after application before surface is cleaned with Proff Intensive Wood Cleaner to remove excess pigments and lime from surface.

9. Leave for drying before application of Proff Oil white or other colour.

Consumption: 1 liter to 8 – 10m2 of woodwork
