Popular Blackfriar Products

Blackfriar's range includes specialised solutions for different staining problems. Their stain-blocking primer formulations effectively seal water stains, smoke damage, crayon marks, and general discolouration, whilst their damp seal products tackle moisture-related issues in walls and ceilings. Many professionals keep both water-based and solvent-based options in their toolkit, choosing the appropriate formulation based on the substrate and severity of the problem.

For particularly stubborn staining or severe damp patches, Blackfriar offers heavy-duty blockers that create an impermeable barrier, whilst their lighter formulations suit minor staining and general preparatory work before decoration.

Frequently Asked Questions

Can Blackfriar damp blockers be used on active damp?

Blackfriar stain blockers are designed to seal historic staining and minor residual dampness, but active damp issues should be resolved at source before application. They prevent old stains from bleeding through but aren't a substitute for proper damp-proofing where ongoing moisture ingress exists.

How many coats of Blackfriar stain blocker do I need?

Most staining requires just one coat of Blackfriar stain blocker, though severe nicotine staining or deep water marks may benefit from a second coat. Always ensure the first coat is completely dry before assessing whether additional coverage is needed.

Can I paint directly over Blackfriar damp and stain blockers?

Yes, once fully dried, Blackfriar products can be overcoated with emulsion, gloss, or other decorative finishes. They provide an ideal base for subsequent decoration, ensuring your topcoat achieves its true colour without stain bleed-through.
