Zinsser Cover Stain®, the all-surface, all-purpose, oil-based primer, sealer and stain killer for interior and exterior use.

Professional decorators, estate maintenance and project managers have another problem-solving product from Zinsser for priming new and previously painted interior surfaces. This oil-based primer is ideal for panelling, wood trim, old wallcoverings, glossy paints, and clear finishes. After preparing the surface, Zinsser Cover Stain® is recoatable in just 2 hours.

Primers and sealers allow for improved coverage and sheen of a topcoat, as well as substrate and surface protection from fungal degradation. This heavy-duty, high end primer seals porous surfaces – plaster, bare wood, masonry, and previously coated drywall – and blocks any tough stains, from nicotine discolouration to smoke damage, and soot to water-stains. It can be applied to metal and other glossy finishes, without the need to sand the surface down prior to application.

Maintenance teams will be impressed by Cover Stain’s ability to prime siding, externally facing shutters, doors and windows, metal, cured masonry, and much more. Its high-performance and durable formula will prevent cracking, peeling, chalking and blistering of the newly applied topcoat. Previous surface damage from graffiti, rust, water and/or mildew are a thing of the past, as Cover Stain blocks and seals them, locking it odours and covering dark colours.

Even the toughest stains do not stand a chance against Cover Stain®, as the oil-based formula seals and blocks them from bleeding through again, like they can do on ordinary surface primers. Restoration contractors can marvel as decades old smoke, soot and nicotine stain residues are permanently blocked. Old fireplace surrounds can be transformed to a new, modern and chic designs.

Cover Stain® can also be used to seal exterior wood, new or old, weathered or untreated, and blocks tough cedar and redwood tannin bleed.

Professional users will agree that Cover Stain offers outstanding adhesion, and even sticks to hard-to-paint surfaces, including ceramic tiles, PVC, weathered wood, glass and glossy enamel paint. It can even be used on metal office cabinets and bookcase, transforming old-fashioned looking offices into new, modern and cutting edge designed workplaces.

Send us your question


Hi I want to paint a varnished wooden framed settee and chairs to use outside. It is very intricate so virtually impossible to sand. Will your cover stain primer bond sufficiently well to it to allow a top coat? Thanks

MARK RANDALL from NORFOLK (UK) - 20/03/17


Zinsser Cover Stain should be fine for this. Provided the surface is clean and free from any waxes or spray polish type materials, the Cover Stain will bond well to the old varnish and provide a good base for a suitable exterior top coat.

What is the best primer/sealer/undercoat to apply to exterior marine ply and softwood? Planning to apply 2 coats of Sadolin Superdec on top.

Peter Dennett from Tenterden (UK) - 29/02/16

Zinsser Cover Stain would be the best primer to use.

Can you thin cover stain?

Paul from London (Uk) - 19/02/16

Zinsser Cover Stain shouldn't be thinned for application as it is designed to be applied as supplied but you can use White Spirit for clean up.

Can Zinsser Cover Stain be used to seal weeping knots?

Roger baker from Horsham (UK) - 28/05/15

No. You would need to scrape away any residue, thoroughly clean the knots with methylated spirits and then apply 1-2 coats as required of Zinsser B-I-N.
