Old Masters Wood Conditioner is a pre-stain, clear wood sealer that enables uniform stain application on soft woods, such as fir, pine, or hemlock. Generally, softer woods accept stain in various degrees creating an uneven appearance; Wood Conditioner helps to eliminate this variance. This product can be applied under oil- or water-based stains. Allow Wood Conditioner to dry for a minimum 24 hours before applying water-based stains. Ideal for use on soft woods which are being stained with or adjacent to hardwoods.
