Pre-Stain Wood Conditioner with an oil-based stain is designed for use before staining new, soft, and porous wood surfaces, such as aspen, cherry, birch, poplar, or pine. It penetrates the wood grain to promote uniform acceptance of oil-based wood stain and reduces streaking and blotching to help ensure beautiful, even coverage. Pre-stain wood conditioner is a PFAS-free formula. As General Finishes strives for a cleaner and healthier environment, all future product development will be free of "Forever Chemicals".
