## Description

Ronseal One Coat Damp Seal White 250Ml

Review: Does exactly what it says on the tin - works perfectly - only needed a small amount to cover a small section so this small tin was perfect
Review: Amazing - 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.

## Questions & Answers

**Q: Doesnt say interior or exterior on the tin, so which is it?**
A: The front design of the tin I received is different to that of the tin in the Amazon photo, possibly a more recent design, and it says: ‘For damp interior walls and ceilings’.

**Q: Can this be used behind a flower bed**
A: Not sure what you mean if you’ve got a damp wall this paint seals it in can’t see why it won’t work the other way !!

**Q: How long does it take to dry**
A: In a standard, warm room, allow around 4 hours at least. If cold, or very damp, allow longer. If wall feels dry to touch, and not crumbly, it should be ok to paint on top, or put plaster over affected area.

This product, although small and after two coats was enough to cover the damp areas. We freshly painted after 48 hours and it's durable to date
