Top tips
Hiring a weather coatings, without the regret.
Four moves that separate a smooth job from a nightmare.
Test the substrate first.
Cement render, pebbledash, brick — different surfaces need different coatings. A proper applicator tests adhesion before quoting.
Insist on a primer + topcoat system.
Skipping the primer halves the lifespan. A coating system (primer + 2-coat topcoat) lasts 15+ years; topcoat-only fails in 5–7.
Don't apply in wrong weather.
Most coatings need >5°C and dry for 24 hours either side. Applicators who push on in November or April are setting up failure.
Check the breathability rating.
Solid walls need breathable coatings (vapour-permeable) — silicone-based, not acrylic. Sealing solid walls traps damp.
