Zinsser's Cover Stain® is an interior / 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 top 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 panelling and trim, where few oil-based primers can succeed. It resists cracking and peeling and is compatible with all decorative top coats.

The primer is white in colour, but can also be tinted to mid-tone colours. It can be applied via an airless sprayer, brush, pad or roller.

Application information:
Coverage: 9.8m² per litre.
Touch dry: 35 minutes.
Hard dry: 4 - 7 days.
Recoatable: 2 hours.

Zinsser CSP400A Cover Stain® is supplied in the following:
