Zinsser Coverstain

Zinsser Cover Stain is the only interior or exterior primer, sealer, stain sealer and bond coat that dries for recoat in only two hours.

On interior surfaces, Cover Stain dries quickly and has great hiding power providing outstanding stain killing and enamel undercoating performance. Stains of all kinds are permanently sealed so topcoats are blemish free.

Cover Stain is especially effective on nicotine and water stains. New wood trim can be primed, sanded and coated the same day, saving time and money.

On exterior surfaces, Cover Stain has a unique formulation that delivers full penetration and flexibility on all surfaces, especially dimensionally unstable wood paneling and trim, where few oil-based primers can succeed. Cover Stain resists cracking and peeling and is compatible with all decorative top coats.


Surfaces must be clean, dry, sound before application. Remove loose or peeling paint by sanding or scraping the surface. If applying to wood, lightly sand exposed exterior wood with a 80 to 100 grit sandpaper to remove loose material.

Stir well before using and do not dilute. The thin, milky liquid can be applied using a brush, medium pile roller or sprayer. Apply the primer liberally, but avoid spilling or dripping. Clean up spills and drips with a wet, soapy cloth or rag and warm as quickly as possible. If excessive absorption occurs over very porous substrates a second coat may be needed.
