Excellent product
This is a fantastic product for covering stains left by mould on walls and ceilings, very thick but still easy application, very happy with my purchase.

Overall great product
Great product, does exactly what it says. It's easy to apply with great coverage. For light damp spots it'll cover in one coat but can add multiple coats for extra sure. The paint is thick so it doesn't run but its easy to apply.

Damp paint
Having only used it 2 weeks ago, it is too early to say if it works to prevent stains. Hopefully it will.

Does what is says on the tin..!!
This product is definitely the best for covering damp patches - and resists any further staining. It cases of sever staining it may take a couple of coats but - it most certainly will l do the job.

Working well so far
Honestly the range of damp seal products and stain stop products was baffling and prices were vastly different. Due to condensation at the skirting board level I had a lot of black mould. I scrubbed it and let it dry and the next day applied this product and then used emulsion. Easy to apply and so far I am really pleased.
