So which one should you buy?

Honestly, the brand choice matters less than the colour choice. A perfectly applied Sandtex in the wrong shade looks worse than a Weathershield in the right one. Before you stand in a Screwfix aisle holding two almost-identical tins of "Cornish Cream", do this one thing: preview the actual shade on your own house photo. The free AI visualiser renders either brand's shade on your walls in 30 seconds, so the decision becomes obvious rather than a £55 gamble.

Once the colour is settled, pick the brand on the criterion that matters for your situation. Coastal, exposed or rendered facade where you want maximum lifespan: Sandtex. Sheltered, brick or DIY weekend job where ease of application wins: Weathershield. Heritage Georgian or Cotswold stone: a Farrow & Ball Exterior or Little Greene Intelligent Masonry mix will out-class both on depth of colour.

Sandtex vs Dulux Weathershield: FAQ

Sandtex or Dulux Weathershield: which lasts longer in UK weather?

Sandtex typically advertises a 15-year lifespan on properly prepared masonry, while Dulux Weathershield Smooth advertises a 10-year guarantee. In practice both perform comparably on sheltered facades, and both struggle on neglected, chalky or damp substrates. If the wall faces coastal salt or sits in a permanently shaded valley, the longer Sandtex guarantee is worth the price premium.

Which is easier to apply for a DIY repaint?

Dulux Weathershield Smooth tends to be slightly more forgiving for a DIY weekend job: thinner consistency, less roller drag and an easier first coat on already-painted render. Sandtex Smooth has a thicker body that gives better coverage in fewer coats but takes more upper-body effort with a roller. For textured Sandtex (high-build), most homeowners hire a decorator.

Sandtex vs Dulux Weathershield: price per litre

At current UK retail (2026), expect roughly £40 to £55 per 5-litre tin for Dulux Weathershield Smooth, and £45 to £60 per 5-litre tin for Sandtex Smooth Masonry. Sandtex usually carries a small premium for the longer guarantee. Coverage is similar at around 16 square metres per litre on smooth render. Trade outlets and Screwfix often beat high-street DIY chains by 15 to 20 percent.

Can I preview both shades on my house before buying?

Yes. Upload a daylight photo of your house to the FacadeColorizer AI visualiser. The first HD render is free with three AI variations, no sign-up required. You can test a Dulux Weathershield shade like Natural Stone or Magnolia, then swap to a Sandtex shade like Plymouth Stone or Country Cream, on the very same photo, before committing to either brand. The Color Pack at £8.90 unlocks 15 distinct tests on the same photo for the price of one tester pot.

What about Sandtex vs Crown vs Johnstone's Stormshield?

Crown Trade Sandtex equivalents (sold mainly through trade merchants) sit between Sandtex and Weathershield on price, with a 10 to 15 year typical lifespan. Johnstone's Stormshield is positioned as a direct Weathershield competitor and is often cheaper at Toolstation. None is objectively the best. The right brand is the one that mixes the colour you can confirm on your own facade photo.
