Passeport Élite Water-based stain This water-based stain is ideal for all interior woods: furniture, cabinets, trim, moldings, doors and floors. It is virtually odorless, does not raise the grain of the wood and leaves no overlap. Apply to a clean, dry, unfinished surface with a sponge and remove excess with a lint-free cloth following the wood grain. To seal and protect the stain, apply a Passeport Élite varnish.
