Zinsser Cover Stain 1 Litre | Premium Exterior Wood Sealer

Two weeks ago failed grouting in shower caused water staining in room below. I left it for a week to dry, including one day with dehumidifier running. This paint is very thick. I used a synthetic brush and it really dragged. I don't think it would be easy to apply with a roller. Having said that, using a 3" brush, (size of tin restricted use of larger brush) putting smallish amounts on it often, it did cover well without much spraying off the brush. Area was ceiling and top of wall, mostly light staining, about 3 square metres in all. I applied two generous coats and the manufacturer's info of coverage (9.8m per litre) is about right. Overpainted with Leyland Trade Super Leytex Matt emulsion, two coats, and that gave a perfect finish apart from one very small area where the staining was very dark. I gave that one extra coat each of the Zinseer and the emulsion and the result is perfect. Heads up. This is solvent based and the fumes are VERY strong. I had to open the doors to ventilate the room. Also, equipment must be cleaned with white spirit. It was recoatable after two hours, although I left the second coat overnight before applying emulsion. The 1 litre tin doesn't have a handle, so I stood it in a paint kettle to make it easier to handle. The Zinsser is expensive, but over decades I've had to deal with similar problems and this was the easiest and most effective method I've come across, so the trade off with price was worth it.

Excellent product. A name I know and trust. Great quality. Does the job. Covered stains and dries well. Would recommend.

Good paint dose the job but the LID WAS NOT ON PROPERLY, good job it was in a plastic bag which retained the paint . It did take a while to clean it up. If I had more time I would have sent it back but needed to get on with the job. This is the second time this has happened to me recently. Please secure the lids properly, do this and I would give your product five stars

Very effective

This cover stain really works well. I used on walls and ceiling. It's not the easiest to apply but I found a soft brush made it easier and very pleased with the result. I painted over with emulsion after and looks great now.

Best primer over gloss paint I can find. Doesn't feel and perfect for base of water based top coat.

The only stain patch paint to use

Covers well but be ready for the strong smell! Packaging was awful, the tins arrived bashed and dented, luckily they didn't leak.

Despues de muchisimas busquedas me decidí por esta imprimación y queda genial!

Ich kann mich meinem Vorredner nur anschließen, auch bei mir kam die Dose sehr schlecht verpackt und stark verbeult an. Fraglich ist, ob man sie so problemlos öffnen und wieder verschließen kann. Sie kam zudem 4 Tage später als angekündigt.

Covered a soot stain with the first coat but added a second to be sure excellent stuff
