Two Very Different Levels of Protection
Masonry paint and exterior wall coatings both protect and enhance your home's exterior, but they work in fundamentally different ways — and the difference shows up in how long each one actually lasts.
| Masonry Paint | Pinnacle Wall Coating | |
|---|---|---|
| Thickness | Thin surface film | ✓ 20x thicker |
| Typical lifespan | 5–10 years | ✓ 20 years, guaranteed |
| Waterproofing | ✗ Limited, degrades with age | ✓ Fully waterproof |
| Breathability | Variable, can trap moisture | ✓ Fully breathable |
| Crack resistance | ✗ Rigid, prone to cracking | ✓ Flexible, moves with the building |
| Algae & mould resistance | Limited | ✓ Anti-fungal formulation |
| Maintenance | Repaint every 5–10 years | ✓ Occasional cleaning only |
Why the Lifespan Difference Is So Large
Masonry paint is, at its core, a decorative surface film. It sits on top of the wall rather than bonding into it, which is why it starts to chip, flake, and fade within a handful of years — particularly on elevations that take the worst of the weather. A wall coating is a different category of product entirely: a thick, resin-based system built to flex with the building through seasonal expansion and contraction, rather than crack under the strain.
That flexibility is the main reason our coatings carry a 20-year guarantee where masonry paint typically needs redoing within 5 to 10 years. Over the lifetime of a property, that difference in repaint cycles adds up to a substantial saving — even though the upfront cost of a wall coating is higher than a simple repaint.
Waterproof, But Still Breathable
The best wall coatings do two things at once that masonry paint struggles to combine: they stop water getting in from the outside, while still letting existing moisture in the wall escape from the inside. Masonry paint, especially once it starts to age and crack, tends to do neither particularly well — water gets in through failed sections, and any moisture already trapped in the wall has nowhere to go, which is often what drives damp patches and mould internally.
Better Resistance to Cracking, Algae, and Mould
Because a wall coating stays flexible, it resists the hairline cracking that rigid masonry paint develops as a property settles and moves with the seasons. Most of our coatings also include anti-fungal additives that actively resist algae and mould growth — a common problem on shaded, north-facing, or coastal walls where masonry paint often turns green within a couple of years.
Cost: Higher Upfront, Lower Over Time
There's no getting around it — a wall coating costs more upfront than a coat of masonry paint. But masonry paint isn't a one-off cost: most homeowners are back on the scaffold within 5 to 10 years, and every repaint adds labour, scaffolding, and material costs on top. A wall coating, applied once and guaranteed for 20 years, is the more cost-effective choice once you look past the first invoice.
Which Is Right for Your Property?
If you're looking for a low-cost, short-term refresh, masonry paint will do the job for a few years. If you want to stop the cycle of repainting altogether — and get a genuine, guaranteed 20 years of protection — a wall coating is the stronger long-term choice for almost every property type, from period homes to modern new-builds.
