JENOLITEStain Blocker Spray Paint | White | 400ml | Damp Seal & Anti Mould Paint for Walls & Ceilings | Immediately Blocks Stains, Mould & Mildew

Left using this until the summer so I could open the back door for ventilation and I was glad I did!However, it has worked brilliantly. We had some bad staining on our ceiling following a leak and it has covered it well. May need a 2nd spray but I was surprised how clean & easy it was to use and how effective it was. Would definitely recommend.

Had mold stains on the ceiling and this covered it well in a two/three layers. Too early to say if it’ll come back but we’ll see. It smells very strong tho so leave windows open for ventilation

Excellent product , does what it says on the can . Will recommend and buy again if needed. No sign of stain reappearing up till now , fingers crossed

I’ve tried all sorts of sprays and paint (including some well known brands) on the damp patches in my kitchen and guess what? Yep, after a few days the damp reappears. The damp stain is from an old leak in the kitchen, so in hope rather than expectation, I bought this spray. It was the only I haven’t tried after all! Well, it has been a revelation. Firstly, it is easy to use. The nozzle allows for precision spraying and even coverage. It does dry quickly, but I left it for a few days anyway. Allow for plenty of ventilation as this stuff stinks. It’s a small price to pay for the prevention of damp patches though. Secondly, paint over. As you can see from the photos it is pretty easy to paint over but you need two coats. It is now impossible to see where the damp patches were as a few quick coats of paint makes it blend in seamlessly with the rest of the wall. Just what I wanted after months of frustration. Time will tell whether it last in the long-term but I’m hopeful. Superb performance and easy to use, even for a DIY novice.

Didn't cover the water stain. Had to purchase another brand that did the job .

I read the reviews and I'm sure it will be useful but the smell is so strong, if summer ever arrives???? will need to open all the windows before I try spraying it again.It arrived quickly, well packed. Not sure yet how well it will work as the short spray I started with was so overpowering with the smell I had to give up. Coverage was very thin but I will review again later once I can give it a fair try.

Works well

Goes on easy and blocks stains well.
