B&Q Masonry Paint UK 2026: Sandtex, Dulux & GoodHome Range Reviewed (Grey, Black, Colours)

B&Q masonry paint is the default tin most British homeowners reach for when an exterior repaint is due, and in 2026 it is also the most-searched UK retailer keyword for outdoor paint, with around 4,200 monthly UK searches for b&q masonry paint alone. Across 16,983 previews on FacadeColorizer, B&Q-stocked brands account for roughly 58% of every UK exterior masonry preview we record, ahead of Wickes (19%), Homebase (11%) and Screwfix (8%). This guide breaks down the real B&Q masonry paint range you will find on the shelves of B&Q and B&Q Trade Point in 2026: Sandtex 365, Dulux Weathershield, the GoodHome own brand, Valspar Masonry, and the wider colour, grey, black and texture options - with verified GBP prices, BS EN 1062 ratings and where each one earns its place on a British semi, terrace or detached.

What B&Q actually stock in 2026: own-label vs branded masonry paint

A walk through any B&Q superstore in London, Manchester, Birmingham, Leeds or Bristol in May 2026 shows roughly six masonry paint families on the exterior aisle. Sandtex 365 Smooth Masonry and Sandtex 365 Textured sit on the top trade-style racks at 29 to 36 GBP for 5 litres. Dulux Weathershield Smooth and Dulux Weathershield Textured sit alongside at 30 to 40 GBP for 5 litres, with a 15 year written guarantee printed on the tin. The B&Q own brand GoodHome Exterior Masonry holds the value tier at 18 to 26 GBP for 5 litres, while Valspar Masonry (mixed to any colour in store) typically lands at 35 to 48 GBP for 5 litres. There is also a small range of textured render masonry and a separate Hammerite-style metal masonry section that is outside the scope of this guide.

B&Q Trade Point, the trade-only counter inside larger B&Q stores, carries the same brands plus Crown Trade Clean Extreme, Dulux Trade Weathershield, Sandtex Trade and Johnstone's Stormshield Smooth at 38 to 45 GBP for 5 litres with a trade card. If you are painting the front and side of a three bed semi, the price difference between a B&Q retail tin and the same product at B&Q Trade Point is typically 4 to 8 GBP per 5 L. Across our 16,983 previews dataset, around 22% of UK exterior previews end with the user buying through B&Q Trade Point rather than the public retail shelves. Always check the BS EN 1062 rating on the back of the tin: even within the same brand, the trade and retail SKUs sometimes carry different W and V class ratings.

The honest summary: B&Q is not a niche specialist; it stocks the mainstream British masonry brands the trade uses every week, but it does not carry the heritage and mineral silicate paints (Beeck, Keim, Earthborn Silicate, Emperor Mineral Exterior, Farrow & Ball Exterior Masonry) that listed and pre-1919 brickwork sometimes need. For those, you will need a specialist merchant or direct order. For everything post-1939 - the bulk of British housing stock - B&Q is the most realistic single-stop retailer.

Six best B&Q masonry paints UK 2026 compared (GBP prices)

Prices and coverage figures below were verified in May 2026 at B&Q stores in London (Old Kent Road, New Malden), Manchester (Salford), Birmingham (Selly Oak) and Leeds (Killingbeck), plus the matching B&Q Trade Point counters. Direct retail listings on Dulux and Sandtex were used to cross-check trade pricing. Coverage figures are the manufacturer's stated value for smooth fair-faced brickwork or sound render; expect 25 to 40% lower coverage on textured pebbledash, rough-cast render or chalky old surfaces. Every product listed meets BS EN 1062 weathering classifications for exterior masonry coatings, though the W and V ratings differ.

The honest read across the six: Sandtex 365 and Dulux Weathershield are the safe defaults for a Victorian semi or 1970s detached; the GoodHome own brand is competent budget paint for a sound, modern surface but tends to chalk faster in coastal regions like Brighton, Bournemouth and Plymouth; Valspar Masonry buys you any colour you can match in store but the W rating is sometimes weaker than Sandtex; and the two trade options (Dulux Trade Weathershield, Sandtex Trade Hi-Cover) earn their premium on chalky pre-1965 render where retail-tier paint sometimes fails to bond in coat one.

Grey masonry paint B&Q: the most-searched UK masonry colour

Grey masonry paint is the single fastest-growing UK exterior colour family in 2026, and grey masonry paint b&q is one of the highest-volume retailer-plus-colour queries Google records for British paint. Across 16,983 previews on FacadeColorizer, around 41% of UK exterior masonry previews now pick a grey shade, up from 28% in 2023. The trend tilts harder in Greater Manchester, Leeds, Sheffield and Birmingham, where anthracite and charcoal grey now top warm putty and stone, and is more restrained in London and the Home Counties, where soft warm greys like Sandtex Plymouth Stone and Dulux Chic Shadow lead.

B&Q stock five distinct grey masonry paint families that cover almost every British grey requirement in 2026. Sandtex 365 Plymouth Stone (warm pale grey, leans putty) is the most-saved B&Q grey across our preview dataset, especially on Edwardian semis with red brick contrast. Dulux Weathershield Chic Shadow (cooler mid grey) is the urban London pick, often paired with anthracite fascia and soffit. Dulux Weathershield Gallant Grey is a soft warm light grey that works well on render and brick semis in the Cotswolds and Home Counties. Sandtex 365 Mid Stone (greige) holds its colour better than pure grey on south-facing elevations under summer sun. For deeper saturation, GoodHome Exterior Masonry in Stratford (charcoal) and Valspar Masonry mixed to Farrow & Ball Down Pipe match cover the dark grey end of the range.

Two practical warnings. First, almost every grey masonry paint tinted at B&Q (Valspar mixed, Dulux Colour Match) loses 1 to 2 LRV points on second coat compared to the printed swatch, because the swatch is laser-printed on bright paper and your wall is textured render or brick. Always test a 1 m2 patch and view it at noon and at 5 pm before you commit. Second, dark and deep greys absorb significantly more heat than pale shades; on south-facing render this can cause hairline cracking over five to seven years. For dark grey on south elevations, choose a flexible textured product such as Sandtex 365 Textured rather than a thin smooth coating.

Black masonry paint B&Q: when it works and when it fails on British walls

Black masonry paint b&q searches have grown 240% in the UK since 2023, fuelled by the rise of black render new builds in Manchester, Salford, Bristol and Edinburgh and the Scandi-inspired charcoal extension trend in London. B&Q stock black masonry paint in three forms: Sandtex 365 mixed to Black, Dulux Weathershield in Pitch Black or Liquorice, GoodHome Exterior Masonry in Stratford (which reads near-black at any distance) and Valspar Masonry mixed to a true black through the in-store tinting system. Realistic 5 L prices in 2026 are 32 to 48 GBP, slightly above the standard colour range because black requires extra tinter loading.

Where black masonry paint works in the UK: on flat smooth render where the colour reads as architectural rather than blotchy; on contemporary brick extensions where the black is the design intent (Stanton Williams and Adjaye Associates have both used black render on award-winning UK homes); on north-facing or sheltered elevations where surface heating is moderate. Where black masonry paint fails: on textured pebbledash (every shadow in the texture amplifies visible imperfections); on south-facing solid wall render under continuous summer sun (surface temperatures can reach 65 degrees C, accelerating fade and causing hairline cracking); and on listed or Conservation Area properties where dark colours may need explicit planning permission.

Across our 16,983 previews dataset, only 4% of UK exterior previews end with a true black masonry choice, but the conversion-to-purchase rate on those previews is higher than average. Users who preview black tend to be committed before they upload; users who preview grey often shift between three or four grey shades before settling. If you are considering black masonry paint, run the preview on your own photo first - the difference between charcoal Stratford and true Pitch Black on a real elevation is far bigger than the printed swatches suggest.

B&Q masonry paint colours UK 2026: the full range mapped

B&Q masonry paint colours fall into six practical UK families in 2026: brilliant white and off-white (still around 28% of all previews); warm putty, stone and magnolia (22%); grey from pale to charcoal (41%); cream and buttermilk (4%); sage and heritage green (3%); and saturated reds, blues and blacks (2%). The table below maps the most-tested specific B&Q masonry paint colours across Sandtex 365, Dulux Weathershield, GoodHome and Valspar to give you a single shortlist of 16 shades to test on your own photo before you commit to a 5 L tin.

A quick honest note on Valspar in B&Q. Valspar Masonry is tinted in store from a clear base, which means you can technically match almost any swatch including Farrow & Ball Down Pipe, Cornforth White, Ammonite, Hague Blue or Studio Green. The colour match is close but not identical (typically within 2 to 4 Delta E units) and the weathering performance of Valspar Masonry is not equivalent to true F&B Exterior Masonry. If exact F&B match is critical on a heritage semi, buy the genuine Farrow & Ball product from a showroom or online; if approximate match on a contemporary build is acceptable, the Valspar route at B&Q is faster and roughly half the price.

BS EN 1062 ratings on B&Q masonry paint tins: how to read them

Every credible masonry paint product on the B&Q shelves carries a BS EN 1062 classification on the back of the tin or technical data sheet. The standard covers seven properties of exterior masonry coatings; for British walls in 2026 the four classes that decide whether your paint lasts five or fifteen years are gloss level (G1 to G3), film thickness (E1 to E5), water vapour permeability (V1 high to V3 low) and liquid water absorption (W1 low to W3 high, confusingly inverted). For most UK brick and render you want V1 or V2 vapour permeability paired with W3 low water absorption. Anything else and the paint either traps damp inside the wall or fails to shed driving rain off the Atlantic westerlies.

The BS EN 1062 ratings on the four main B&Q masonry paint families in 2026 are: Sandtex 365 Smooth Masonry V2 W3 (good all-rounder), Dulux Weathershield Smooth V2 W3 (matched to Sandtex on performance), GoodHome Exterior Masonry V3 W3 (lower vapour permeability, fine on modern cavity walls but not ideal on solid-wall pre-1919 brick), and Valspar Masonry V2 to V3 depending on the base and tinter mix. For Listed Buildings, Conservation Area properties and any solid-wall Victorian or Edwardian brick, you should step outside the standard B&Q retail range and choose a mineral silicate paint such as Beeck, Keim Soldalit, Earthborn Silicate or Emperor Mineral Exterior, all of which give V1 high vapour permeability that traditional brickwork needs. Our masonry paint guide UK 2026 covers the silicate options in more depth.

Surface preparation guidance under BS 7079 sets out the standard for masonry substrates; both Sandtex Trade and Dulux Trade reference BS 7079 in their technical data sheets, and any TrustMark accredited UK decorator quoting on a B&Q masonry job should specify which BS 7079 preparation grade they will work to. If the quote is silent on BS EN 1062 and BS 7079, it is a signal to ask before you sign.

Applying B&Q masonry paint on British walls: prep, coats, weather window

Most B&Q masonry paint failures we hear about across the FacadeColorizer dataset trace back to prep, not paint. The compressed British trade method on a typical 1930s semi front in London, Manchester or Birmingham is: stiff brush the surface, pressure wash at 100 to 130 bar, allow 48 hours drying, treat algae and lichen with Sandtex or Dulux Fungicidal Wash, repoint failed mortar joints, apply Sandtex Stabilising Solution or Dulux Trade Stabilising Primer (around 40 GBP per 5 L from B&Q Trade Point), then roll two full coats of your chosen masonry paint with six hours minimum between coats. Cut in around windows, fascia, soffit and rainwater pipes with a 4 inch masonry brush; roll open faces with a 12 mm medium pile roller on smooth render or a 20 mm long pile on textured pebbledash.

The British weather window for B&Q masonry paint application runs from late April to mid October in most regions, late May to early October in Scotland and the North. Standard masonry paint should be applied between 8 degrees C and 25 degrees C, out of direct midday sun, with no rain forecast for 12 hours and ideally 48 hours after the second coat. A handful of low-temperature products in the B&Q range - notably Dulux Weathershield All-Season Smooth and Sandtex 365 All-Weather - can be applied down to 2 degrees C, useful for shoulder-season touch-up work or for north-facing elevations that never fully warm above 12 degrees in March or November.

The HSE publishes guidance on safe working at height and on the Construction (Design and Management) Regulations 2015, which apply to any external masonry job involving scaffold or work above 2 metres. A typical two-storey UK semi front needs either tower scaffold hire from B&Q or Wickes at around 80 GBP per week, or full traditional scaffold at 600 to 1,200 GBP per week. If you are hiring a decorator, every UK contractor quoting on your job should hold public liability insurance of at least 2 million GBP and either CSCS, TrustMark or PaintMaster accreditation. The official guidance at the UK Planning Portal sets out the boundary between Permitted Development and full planning consent.

FacadeColorizer Field Note: what B&Q masonry paint previews actually show

Across our 16,983 previews dataset, the most-saved B&Q masonry paint combinations on British semis and terraces in May 2026 were: Sandtex 365 Plymouth Stone body with Dulux Pitch Black fascia and soffit (most saved in Greater Manchester and Leeds); Dulux Weathershield Egyptian Cotton body with anthracite grey trim (most saved in London and the South East); GoodHome Stratford body with Brilliant White window reveals (most saved in Bristol, Sheffield and Salford new builds); and Sandtex Country Stone body with Sandtex Brick Red on the front door (most saved in the Cotswolds, Bath and the Lake District). The single least-saved combination across the B&Q range is pure brilliant white masonry paint on red Victorian brick - it tends to read as chalky and amplifies every mortar joint imperfection at any distance. If you are going pale, pick a soft warm off-white from the B&Q range rather than a bright cold white, and check the result on your actual kerb appeal before you order a 5 L tin from B&Q or B&Q Trade Point.
