Old Masters® Wood Conditioner is a pre-stain, clear wood sealer which 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, but stain must be applied over Wood Conditioner within 2 hours. Ideal for use on soft woods which are being stained with or adjacent to hardwoods.
