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!

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

Good value
Works well on where damp patches have been on ceiling. Dries really well, definitely worth the money. The smell soon clears with the windows open and covers really good no sign of where he marks were.

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 .
