Spray cork lifespan and maintenance
How long spray cork lasts in the UK climate, what shortens its life, and the light maintenance that keeps a coated wall looking right.
Last updated
Manufacturers typically quote 20 to 30 years for a spray cork finish. That figure assumes correct preparation, an appropriate substrate and occasional cleaning.
What to expect
In practice the coating outlives its appearance: the material may still be sound while north-facing elevations have picked up algae or the colour has softened. Most owners are looking at a clean or refresh rather than a full recoat within that window.
What shortens it
Poor preparation, movement in the substrate, persistent damp and overhanging vegetation are the main culprits. Coastal and heavily shaded properties tend to need cleaning more often.
Sensible maintenance
Keep gutters clear, cut back planting touching the wall, and wash down gently every few years. Avoid high-pressure washing, which can damage the textured surface.
Common questions
Does spray cork need repainting?+
Not in the way masonry paint does. Most owners clean rather than recoat, though a refresh coat is possible later in its life.
Is a guarantee the same as a lifespan?+
No. A guarantee is a commercial promise with exclusions, usually shorter than the quoted material life. Read what it actually covers.
