Silicone vs Acrylic — The Straight Answer

Silicone is breathable, which matters in Kent's damp winter climate — it lets moisture from inside the wall escape rather than trapping it behind the coating. It is also hydrophobic on the surface, so rain sheets off and washes dirt with it. Expect 20–25 years before a recoat.

Acrylic is a plastic-based coating. Cheaper, wider colour choice, holds sharp edges well. Downside: less breathable, and in shaded, tree-lined streets it can green up with algae within 5–7 years and need cleaning.

Our default recommendation for Kent: silicone on north- and east-facing walls, silicone-silicate on solid-wall Victorian properties, and acrylic only where budget is the priority and the elevation gets sun.
