Why use a stain blocker spray?
Regular paint won’t cut it - stains and damp marks just show through again.

Our Damp and Stain Blocker Spray is more than just a damp seal paint for internal walls – it’s a shield against moisture, mould and an array of stains, including nicotine, smoke, rust, grease, crayon and pen.

Easy to use, supplied in a handy aerosol can – it reaches awkward spots with ease. Quick drying in just 10 minutes, you can block mould, watermarks, and stains in no time.
