Ronseal One Coat Damp Seal - White 250ml

works perfectly - only needed a small amount to cover a small section so this small tin was perfect

The tin is only small so be mindful of this before you consider buying for a large area or areas. The paint is spreadable regardless of previous comments however it does dry quick and drys very smooth. I cut out a thin layer of the old plaster first to allow the area to dry for 24hrs before applying to allow for better contact. Excellent product well worth the money.

Covered but like with all 1 coat paint you always need a second coat to make sure

The Ronseal One Coat Damp Seal in White is an excellent product for covering water stains. I have found it to be highly effective in concealing and preventing the appearance of damp patches on walls and ceilings. With just one coat, it provides excellent coverage and adheres well to various surfaces, creating a smooth and uniform finish. The white color blends seamlessly with existing paint, making it perfect for touch-ups or refreshing the appearance of affected areas. A Great product that works !

Have used before it works
