No Nonsense Stain Sealer White 400ml
Used some of this on a number of plaster substrates in an old house. Having used brush-on damp stop on other areas, I was pretty disappointed by the performance of this. Other damp stop paint I have used forms a vinyl layer which is a barrier to moisture. This stuff leaves a chalky layer which does not stop the passage of moisture or associated staining.

Doesn't block all stains
Have used this a few times now- blocks out most stains but have had some water stains that Ive put 3 coats of sealer on then painted- and the stains shown back through.

Good for small areas
Several thin coats work best. Does not go far so for larger areas a brushed alternative such as Zinsser is better.

Great stuff, covers quickly and easily. Dries fast so good for a top coat not long after drying. Being a spray paint means it does go a but everywhere so not good in tight spaces near other painted surfaces unless everything is covered.
