Ronseal OCDSW500 500 ml One Coat Damp Seal - White

done the job, no damp or mould patches were i coated the walls. been 8 months now. good product.

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

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.

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 .

Small tin good job it’s only a small area. I’ve painted it 3 times and it still hasn’t covered the stainsNot as promised tin states just 1 coat needed

I needed a damp proof paint for my outside wall as paint was peeling and I could see mould underneath.I used this Ronseal after preparing the wall. That was 2 weeks ago. It's covered the area nicely. No mould is coming through and no more peeling paint. It worked very well. I will paint over it with sandtex masonary paint and my wall will be good as new. Great stuff. Don't hesitate to buy.

Painted onto wall so hopefully will make a difference but only time will tell.

Only a small tin but goes a long way. So far product covered damp, gave two coats and has been a couple of months & not resurfaced, so would recommend
