JENOLITE Stain 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

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.

Easy to use and so far no sign of the stain. The can covered 3 x 1msq. After the three coats the can was empty but it has sealed the wall. Finished with 3 coats of emulsion which has matched the rest of the wall. Decent price. Will no better in a few months time if the stain starts to show. The wall was not damp so unable to comment on how it might work on a damp prone area.

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

Easy to apply and managed to apply 3 coats horizontal and vertical before it ran out. Gives a good coverage and looks good when applied

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

Did what it said on the tin. Covered some bad water stain marks on ceiling and wall. Easy to use.
