Ultimate Sealer for All Surfaces Water Based, Non Toxic, No VOC, Made in USA, 100% Certified Safe Great Penetration To Create A Strong Barrier Against Moisture One of our most popular products. A sealer is the first step in ensuring that what you paint, stain, or decorate maintains the look you want and doesn't deteriorate over time, and this seals porous surfaces, forming a barrier to keep anything on the inside from bleeding through and anything on the outside from penetrating back through the surface. A non-toxic water-based sealer that completely seals furniture, new or old wood (keeping the moisture from green wood from seeping through), cabinets, craft projects, walls, inside or outside, wood floors, terra cotta, cement, brick, concrete and more. Keeps the internal moisture in and the external wetness out. Can seal knots in the same way. Earth Safe Finishes has been manufacturing safe products for over 25 years.
