Rated 1 out of 5 by from Wall damper than ever I have now applied this damp seal coat over a month ago, on a living room wall perfectly dry which previous paint suffered damp issues from condensation. Painted it over with a valspar paint the following week and 3 weeks later that paint is still not dry where the damp seal has been applied. It constantly leaks and leaves streaks of paint on the wall, even with a heater fan blowing on it for days. I thought I had a serious leak issue from the window but I am now getting the same result in the bathroom where I applied a coat too and only just painted over. I gonna have to scrap it all in both rooms, sand the walls and start all over again with a different product. I highly don't recommend using this as an undercoat or primer it makes more of a mess than preventing any.

Rated 1 out of 5 by from Unusable product Really poor product .... it is far too thick to paint on to walls and has run badly. The wall looks like a badly iced cake. The whole lot will have to be sanded off

Rated 2 out of 5 by from Very thick paint I bought the product to help with a damp wall due to leak from bathroom, the wall had dried out over a couple of months as didn’t want to rush painting it. Got this paint to help cover up the stains before I painted with emulsion. Very hard to work with as it’s so thick. Left over night to dry, painted the wall with emulsion and this paint is coming through and leaking streaks in the paint work! So now at a loss to what to do as I don’t want to have to start all over again.

Rated 1 out of 5 by from Very disappointed Bought this to cover over some damp marks on a bedroom wall. We washed wall with sugar soap, which removed about 60% of the marks and left to dry overnight. The following day I applied the Damp Seal by roller, it is thick but went on OK. Left for 48 hrs then applied a silk emulsion. Despite four coats of paint, I have white spots showing through and a vertical white shadow following the line of the batoning under the plasterboard. I do not understand what is going on.

Rated 1 out of 5 by from The worst purchase Used today on small bedroom wall took over an hour to cover. Very difficult to work with. Does not give smooth application.

Rated 1 out of 5 by from Awful product - Ruined ceiling Terrible product. Applied to a ceiling which had been freshly skimmed, correctly dried and mist coated. Applied Damp seal. Left to dry for a few days, came to paint and the paint wouldn’t adhere or cover the damp sealant. We now have an expensive mess. We have had to sand down, repaint numerous times, use filler to cover and still not right 2 weeks on. Pursuing Valspar for compensation. We are extremely unhappy.

Rated 5 out of 5 by from Works as advertised! I had big issues with a leaking window. I had that problem sorted and applied this damp seal after allowing a bit of time for the plaster to dry out and not be saturated. It does apply very thickly with a lot of drag but once on, and dry and top coated I have not had any further issues with damp or stains. very happy with the results.

Rated 1 out of 5 by from Far too thick painted this on a patch where we had damp and it's so thick despite me trying to make sure it wouldn't run I went back after an hour and it had slowly run thickly down the wall leaving a 'landslide' of paint along the wall which I will probably have to sand before I can paint over it
