Wondering if you can paint over previously painted brickwork or render without it flaking off weeks later? You can—but it starts with the right masonry paint and the right preparation. This guide covers everything you need to know to make your next exterior project last.
Step-by-Step: How to Paint Over Previously Painted Masonry
1. Check the existing coating
Scratch the surface. If paint flakes easily, it may not be sound. Use a scraper or stiff brush to remove loose paint.
2. Clean the surface
Dirt, algae, mould, and pollution can all affect adhesion. Use masonry and brick cleaners designed for exterior substrates. Rinse thoroughly and allow to dry completely.
3. Repair cracks and gaps
Fill all cracks and holes with appropriate exterior filler. Let it dry, then sand smooth. Uneven repairs will show through fresh paint.

4. Prime bare or porous areas
If you’ve exposed bare brick, stone, or render, spot prime with a suitable masonry primer. This prevents patchiness and improves coverage.
5. Choose the right paint
Pick a high-performance masonry paint that is compatible with the existing coating and can resist British weather. Breathable, flexible finishes are ideal for older walls.
6. Apply in dry weather
Always check the forecast. Avoid painting if rain or low temperatures are due within 24 hours. Use a brush, roller or airless sprayer depending on the surface area.
7. Apply two coats
Let the first coat dry fully before applying the second. Follow the manufacturer’s drying times exactly. Most systems require two coats for full durability.
Bring Life Back to Gutters and Window Frames
Whilst you’re outside updating your walls, look at the gutters and downpipes. These often fade, crack, or peel before masonry does but, instead of replacing them, you can paint uPVC in thousands of colours – even windows and doors. This saves money, reduces waste, and freshens up your home’s appearance instantly with a modern look.
Add Colour and Protection to Fences and Sheds
Fences, sheds, and wooden trims are just as visible as your masonry. They’re also more prone to moisture damage. When refreshing your exterior colour scheme, consider paints that protect timber and bring your whole garden scheme together. Choose finishes that match your walls or contrast them for a bold upgrade.
