Masonry paint for pebbledash

Updated: October 2026

You are looking at a grey pebbledash wall, and the tin in the shed quotes a coverage figure written for flat render. Masonry paint for pebbledash has to sit in the gaps between the stones, so the same litre covers far less than it would on a smooth wall. This page is the quantity, the tools, and the point at which you stop. Listings are on the [white masonry paint comparison](/hub/paints-and-varnishes/white-masonry-paint), and a qualifying purchase there can earn us a commission at no extra cost to you. Plan the rough rate, work the film into the recesses, and leave a failed dash unpainted.

Pebbledash takes more paint than the headline

The number on many smooth tins is the kinder surface. Sandtex lists smooth masonry paint for pebbledash, and the headline on that range is about 12–16 m² per litre, which changes with texture. Dulux Trade's Weathershield smooth sheet is clearer for dash: up to 16 m² per litre on smooth render, and about 4–6 m² per litre on pebbledash, after a trial area. Buy against that 4–6 band. A flat-wall calculation will run out before the second coat.

Brush the gaps, then roll

A short-pile roller rides the crowns and leaves the hollows grey. Toolstation's guide uses a long-pile roller in several directions, then a masonry brush stippled into the recesses. A roller alone still misses the deepest pockets on a coarse dash. Cut in before the roller takes the main face, and keep the brushed edge no thicker than the rolled film, or the border dries as a picture frame around a window reveal. Dulux and Sandtex sheets name pebbledash for smooth masonry paint. Toolstation's guide also says smooth paint is not suitable for pebble dash, which conflicts with those sheets. Follow the data sheet on the tin you bought. The brush and roller only help if the dash is still attached and dry.

Repair and dry the dash first

Loose stones are a render fault, not a shortage of paint. Repair loose dash before you paint, because a coat over stones that move will crack with them, and new paint will not glue a failed coat back to the wall. These paints are for a sound, dry mineral wall. A wall that is wet, green with algae, or chalky under your hand is not ready, and paint over flakes traps the failure. Do not treat masonry below the damp-proof course, where moisture cannot escape, as the same job as the elevation above it, and do not use this set on lime render. Rain held in the gaps outlasts a dry forecast. Once the tin is open, the weather window sits on how to apply masonry paint.

What this page does not decide

Dash is already the texture. A smooth film leaves it in place, which is why the Dulux and Sandtex sheets can name pebbledash without a textured tin. Roughcast shares the litre problem, though a shallow texture drinks less than a deep dash. This page does not rank tins. Pack size, shade of white, and which amazon.co.uk listing fits a patch or a whole elevation belong on the main comparison. Buy at the 4–6 m² per litre band, allow two coats, trial a patch, and work the paint into the gaps. Loose or damp dash will not be rescued by more litres.

Common questions

Can white masonry paint go on pebbledash?
Yes, when the dash is sound and dry and the sheet lists pebbledash or roughcast. Sandtex lists smooth masonry paint for that surface, and Dulux Trade's smooth sheet gives about 4–6 m² per litre on it. A retailer guide that dismisses every smooth paint conflicts with those sheets, so follow the tin you open. A strong colour change still needs two coats before the recesses look even.
Should I use smooth or textured paint on dash?
The dash is already textured, so smooth masonry paint is the film those sheets describe. Textured paint is heavier and covers fewer square metres per litre, which suits small irregularities rather than every dashed wall. The two films are compared on the smooth or textured masonry paint page. If your tin excludes dash, that sheet overrides a retailer sentence.
How many square metres per litre should I plan?
Plan about 4–6 m² per litre per coat on pebbledash, from the Dulux Trade smooth sheet, and trial a patch because stones vary. The 12–16 m² per litre headline is the kinder wall. Emperor's figure of about 2–3 m² per litre is for that silicone paint on texture, and BuildWiz's 2–3 m² is a publisher estimate. Do not average those with 4–6.
Is a brush or a roller better for pebbledash?
Use both. A long-pile roller covers the crowns, and a masonry brush pushes paint into gaps a short pile misses. One sequence uses a 4-inch brush for the first coat and a long-pile roller for the second; you can also roll first and then stipple. Keep the brushed edge no thicker than the rolled film, or the border dries as a ridge.
What if the stones are loose or the wall is damp?
Repair loose dash before you paint. A new coat will not hold stones that already move, and a spreading hollow needs a renderer rather than a thicker film. Paint only a sound, dry wall. Algae, flakes, and masonry below the damp-proof course are stops, because trapped moisture pushes the film off. Rain in the gaps outlasts a dry afternoon.
Will one 5 litre tin paint a pebbledash house?
Not a whole house at two coats and 4–6 m² per litre. On a worked example of 24 m², two coats need about 8–12 litres, so one 5 litre tin is one coat at the kinder end. At 4 m² per litre, 5 litres covers 20 m² once. Leyland 5 litre reviews that mention pebbledash confirm the surface, not the quantity for your walls.
