Rated 1 out of 5 by Completely useless This product is completely useless. In fact its worse than useless, as after using it the damp problem and the damage got a lot worse. I had a small (3cm) damp patch on my ceiling. I applied a couple of coats of damp seal and then after it had dried three coats of emulsion. The ceiling looked great. Then it rained, and the damp patch came back. This time I applied three coats of damp seal to a wide area of ceiling, not just over the damp patch, then painted as before. The result was not only is the damp patch back and bigger, but I also I now have a bulge in my ceiling next to it, about 50cm long. Not only has all my hard work been ruined, but I now have another expensive repair job to fix the ceiling as well. The same thing happened on a wall. I tried one coat of damp seal, but it didnt work, and the bubbles kept coming back. Eventually I resorted to six coats of damp seal followed by three coats of emulsion, allowing a couple of days for everything to dry between each coat, and it still didnt work. On the contrary, the damage just kept getting worse. Once again I'm going to be faced with an expensive repair bill. All I can say in conclusion is please don't waste your hard earned cash on this completely useless product! I've given it one star because that's the lowest rating, but I don't think it deserves any stars. 09 May 2013
Rated 5 out of 5 by DAMPSEAL THIS PRODUCT DOES (IF APPLIED AS INSTRUCTIONS) EXACTLY AS IT SAYS ON THE TIN EASY TO APPLY AND GREAT RESULTS 06 March 2013
Rated 4 out of 5 by So far, so good Used this product to clear mould damp from condensation. I first cleaned off the mould and applied the Polycell Damp Seal. It appears to have done what it says on the tin, time will tell but, so far, very pleased. 09 January 2013
Rated 5 out of 5 by Excellent Went onto the walls really easy, have got to wait to see if the damp come through now, so far so good after 1 month. Did not know what to buy when I went to the shop, staff members where very helpful 09 January 2013
Rated 5 out of 5 by Excellent damp cure! Does as it says on the tin. Very impressed with this product so far.|There are few products like this on the market. PAints over very easily. Make sure you use breathable paint to do this. Dulux trade emulsion is the best, according to professionals! Would buy again! 09 January 2013
