Will Deck Stains Work Inside?

No, they cannot be used indoors. Exterior wood and deck stains are designed for outside use only. The chemical makeup is much different than an interior stain like Varathane or Minwax wood stains. Exterior wood and deck stains contain additional ingredients not found in interior stains, such as trans oxide and acrylic pigments, water repellent properties, and mildewcides. Exterior deck stains will not penetrate as deep into the wood grain as interior stains and cannot be top-coated with polyurethanes or varnishes. Adding a top coat over an exterior wood or deck stain will result in peeling.
