So far so good
Delivery was good it was packed very well . I’ve only done one coat so far on a corner wall which my paint started flaking on . I scraped all the paint away first and washed away the small amount of mould with a bleach based spray and a mould remover to do extra . The wall was cold dame feeling when i applied it. It’s thicker than normal paint but applies really easy I used a brush . It’s great coverage . I have to do a second coat but in some places I applied it thick enough that it won’t need a second a coat. I’ve had to do quite a big space and the 2.5 litre looks like it’s plenty even after doing a second coat . The smell is a like lighter fluid , it’s not that strong but the room does need ventilation . Lucky for me it’s a very windy day today . Will update once it’s all dry and done for a few months .Now July and the wall is good so I’m glad I got this . I would say the weather has been good but summer is nowhere to be seen and the wall hasn’t flaked or peeled it’s still fresh. Will update again in winter .Now February 2025 and we have seen some terrible rainy weather in the last year and my wall has stayed perfect . No flaking, peeling or discolouration was definitely a good buy .Now July 2025 the wall is good no flaking peeling or damp coming back through . Just uploaded photos of the wall.I have done terrible DIY job as I have used the wrong colour white paint .Also I haven’t done a good job managing the drips down the wall which is all my fault not the damp paint or any paint . I have to repaint my whole room white to match but the damp paint has done a great job !

Lasted a few months in the bathroom
Bought in September, it's prevented the mould in my bathroom with bathroom paint up until February of this year. Not bad. Doesn't block but has worked for a while

Does exactly what it says on the tin
I was sceptical that this would resolve an issue with a small damp patch in the corner but it worked perfectly, it's quite thick to apply but covers well and no issues since!

Really good covers the damp easily
I was pleasantly surprised as l wasn't sure it would hide and seal the damp but it has. It smelt a little but not too badly. Went on my walls easily and looks really good. I would certainly recommend this item
