Rated 1 out of 5 by from Did not work for me I used this product to try to cover a stain left on a wall caused by a leaky union on some guttering. Repaired the guttering, let the wall dry out and then used this product. I followed the instructions and gave it 3 coats. The wall looked good so I gave it a coat of the white emulsion that had been used on the wall previously and then the stain came through it. Would not recommend of the wall you are trying to cover a stain on is white. I've previously used zinsser cover stain which worked well and I will return to that product.

Rated 4 out of 5 by from Works Well but Mind the Fumes! Product works really well but the solvent fumes are very strong and you need a good dose of ventilation.

Rated 5 out of 5 by from Can’t fault it Had a rather annoying brown water stain on the ceiling and top of the wall and this covered it up splendidly. As instructed used 2-3 light coats and you can no longer see the stain at all. The ceiling barely needs a coat of emulsion and the wall, which was a sunshine yellow colour has covered over really well. Well worth it!

Rated 5 out of 5 by from No Nonsense Stain Sealer Purchased this product to seal some water stains and felt tip markings on emulsion pain. Was actually suprised at how good and easy the product is to use. It saved me a lot of time and headache allowing me to finish the job much sooner than I anticipated. I will definately use again and have already bought another can in anticipation of doing so.

Rated 5 out of 5 by from Great versatile product . I have used this product for various purposes, the most recent being sealing /painting a tired pine bookcase to produce an excellent "shabby sheek" finish in white.No need to rub down the existing finish.I also recommended it to a friend to seal the ceiling where there had been a water leak ... job done !

Rated 5 out of 5 by from Works Where Most Others Fail. I first used this on a rising damp stain in my living room a few years ago and it sealed and blocked the stain from returning. I used it again recently on a few small greasy looking stains appearing through my front internal wall. Two applications and two coats of emulsion later and the job is done. I've used numerous so-called damp seals and they either don't work or cause a reaction, leaving marks. This is the real deal. Highly recommended.

Rated 5 out of 5 by from Good coverage The first coat was not so good, though probably did not shake the can enough! The second coat 20 min later did the trick. Excellent coverage for small areas but could work out quite expensive if you had a large area to cover. Would definitely recommend it.

Rated 1 out of 5 by from Spray dust everywhere, avoid Ok, it DOES cover stains, but the amount of time need to be spent on cleaning the entire place due to enormous spray dust is not worth it. I used to rely on No-Nonsense products for regular DIY work at home but surely will not recommend this one. Quite disappointing.
Date published: 2020-05-07
Rated 5 out of 5 by from No Nonsense stain paint I get mould stains in my en-suite ceiling. Having tried every type of cleaner without success there is always a remnant of a stain. This purchase was my last chance before I have the ceiling skimmed. Having read the reviews I was hoping that this would sort out the problem. I sprayed the stains using a piece of cardboard to prevent overspray, the stains were covered by the paint, I left it to dry for 30 mins and repeated the process. To my amazement the stains are gone and the ceiling looks fantastic. I would recommend this product to anyone with similar problems.

Rated 3 out of 5 by from Stain Sealer ? I use No Nonsense products a lot, but this one falls short of the mark for me. I found it didn’t cover nicotine stains as well as products like Zinsser Cover Stain. Unfortunate, as other products in the no nonsense range are very good.
Date published: 2020-02-22
Rated 5 out of 5 by from Good product. Easy to apply product with good quality spray nozzle. Fine textured, brilliant white finish that is silky smooth. Used 2 coats and was completely adequate. Yes, there is a strong acetone smell but that’s to be expected. After spraying the ceiling in three small patches from approx 15-20 cm distance and being very careful, on returning to the room after approx 10 mins to allow it to dry, the surface of EVERYTHING in the room was left with a fine but relatively thick layer of white dust from the settling of the paint molecules in the air. Only half the room had been dust sheeted but it took a good hour to clean all the surfaces. Otherwise a good product but be aware of the above point.

Rated 5 out of 5 by from Rust stain from radiator - jus Bought this as my radiator had burst, rust stain over wall and ceiling, this covered the stain perfectly, well impressed and not that expensive
Date published: 2020-02-18
Rated 5 out of 5 by from This product works It seems you can always rely on Screwfix's No Nonsense products. They just work and don't cost an arm and a leg like some brand-name products. This Stain Sealer covers well and is a proper brilliant white matt paint that matches any other regular matt emulsion. Works best in multiple, thin coats. When it says to work in a well-ventilated room, it really means it. The smell of acetone can get overpowering, but it does seem to disperse fairly quickly if you keep the windows open.

Rated 5 out of 5 by from Magic. I have used this on many decorating jobs especially childrens bedrooms, if you have felt tip or crayon marks on the wall, spray this on first once you have shaken the can for 2 minutes and within 30 minutes it is dry and ready to paint over, no smudging or bleeding through, makes life so much easier.
