Protego Wood Lye may be used for all new, freshly sanded soft wood such as Pine, Pitch Pine, and Spruce used for floors, wall and ceiling panels, and furniture with maximum moisture content of 12 – 14 per cent. The wood work may be either solid or laminated wood panels. If Wood Lye is used on hard wood species such as Oak, it will produce a fumed colour. To lighten hard wood, Protego Wood Lye is recommended. Wood Lye is not suitable for engineered floors with thin top layer veneer. It may cause de-lamination of veneer.
