Six brands dominate the UK exterior masonry paint market in 2026 — and the gap between the best and the worst is wider than most homeowners realise. A £35 tin that lasts five years is not cheaper than a £55 tin that lasts fifteen. Below is our ranked shortlist of the six best exterior paint brands for British homes this year, with real 5L prices pulled from trade merchants in April 2026, coverage rates, warranty terms, and where each one genuinely earns its place on the scaffold.

6 Best Exterior Paint Brands Ranked for 2026
1. Dulux Weathershield Smooth Masonry — the benchmark
If there is a "default" choice for British homeowners, this is it. Dulux Weathershield Smooth Masonry is BBA-certified, water-based, and — crucially — now backed by a genuine Lifetime Guarantee against peeling, flaking and mould staining, provided you register within six months of purchase. Coverage is around 15 m² per litre per coat, so a 5L tin covers roughly 75 m² — comfortably enough for the front elevation of a three-bed semi.
- Price (5L): £42–£52 at merchants such as MKM, B&Q and Paint Direct
- Coverage: up to 15 m² per litre per coat (≈75 m² per 5L)
- Warranty: Lifetime Guarantee (Weathershield Promise) with registration
- Best for: owner-occupiers who want the least hassle and the strongest brand-name guarantee
2. Sandtex Trade 365 All Weather Masonry — the decorator's favourite
Ask any professional decorator on Checkatrade what goes on exterior walls in February and the answer is almost always Sandtex Trade 365. It uses Pliolite technology that allows application in temperatures as low as -10°C, develops showerproof protection within 20 minutes, and is marketed with up to 20 years of proven durability. The 5L tin retails from around £48.50 ex-VAT at Brewers and other trade suppliers — a fair chunk more than retail Sandtex, but with significantly better weather resistance.
- Price (5L): from £48.50 ex-VAT (≈£58 inc-VAT) at Brewers, Next Day Paint
- Coverage: up to 16 m² per litre (≈80 m² per 5L)
- Warranty: up to 20 years durability (manufacturer statement)
- Best for: winter exteriors, coastal properties, commercial facades
3. Crown Trade Sandtex Ultra Smooth — the specification stalwart
Sandtex is owned by Crown Paints, and through the Crown Trade channel you also get access to Crown Trade Sandtex Ultra Smooth Masonry — a specification-grade product that sits just under the 365 range on price but outperforms most retail options. It is the paint most commonly listed on local authority housing schedules and on Dulux Decorator Centre ticket prices. Typical 5L tins sit around £32.49 retail ready-mixed, rising with tint.
- Price (5L): £32–£42 ready-mixed (tinted slightly higher)
- Coverage: up to 14 m² per litre (≈70 m² per 5L)
- Warranty: 15 years typical product life
- Best for: landlords, HMOs, housing associations, larger repaint projects
4. Farrow & Ball Exterior Masonry — the heritage choice
If you live in a Georgian townhouse in Bath, a listed cottage in the Cotswolds, or a period terrace in a conservation area, Farrow & Ball Exterior Masonry is hard to beat for depth of colour and historically accurate shades. It is, however, the most expensive option on our list — a 5L tin sits around £128 at The Paint Shed and similar specialists. You are paying for pigment, not just durability.
- Price (5L): ≈£128 at specialist retailers
- Coverage: up to 12 m² per litre (≈60 m² per 5L)
- Warranty: 15 years weather resistance (manufacturer)
- Best for: listed buildings, conservation areas, heritage restoration
5. Leyland Trade Truguard Smooth 15 Year Masonry — the value workhorse
Leyland Trade Truguard Smooth 15 Year Masonry is one of the most quietly competent products on the market. It is the paint many decorators reach for when a landlord wants "tidy and done" rather than show-home finish. A 5L tin typically sits at £35–£42 at Next Day Paint, Decorating Centre Online and Leekes. The 15-year product life on the tin is genuine — we have seen it tested and standing up on a 2010 rental repaint in Yorkshire.
- Price (5L): £35–£42 white, £45–£55 tinted
- Coverage: up to 14 m² per litre (≈70 m² per 5L)
- Warranty: 15-year product life claim
- Best for: rentals, large surface areas, budget-conscious repaints
6. Wethertex PP77 Pliolite Masonry — the breathable specialist
Sold through the Leyland Trade network, Wethertex PP77 is the one you choose when your substrate might still be holding moisture — old render, lime substrates, stone cottages in Devon. It is a Pliolite paint: solvent-based, breathable, and extraordinarily opaque in a single coat. Expect to pay around £55 for a 5L tinted tin. It is the only product on this list decorators still describe as "one-coat capable" in most colours.
- Price (5L): ≈£55 tinted (white slightly cheaper)
- Coverage: up to 10 m² per litre (≈50 m² per 5L)
- Warranty: up to 20 years protection (manufacturer)
- Best for: old render, cob, lime substrates, damp-prone walls

How to Choose the Right Brand for Your Home
The honest truth is that for a typical three-bed semi in brick and render, three of the six brands above will do a perfectly acceptable job. The question is which one matches your priorities.
- If you value peace of mind above all: choose Dulux Weathershield — the Lifetime Guarantee is the strongest in the market
- If you must paint in cold or wet conditions: Sandtex 365 is the only product that will cure reliably below 5°C
- If the house is listed or in a conservation area: Farrow & Ball or a breathable lime-compatible paint such as Wethertex PP77
- If the substrate might be damp: Wethertex PP77 (breathable Pliolite) — never trap moisture behind acrylic film
- If you are painting a rental and counting pennies per m²: Leyland Trade Truguard gives the best coverage-per-pound ratio
- If you need a spec-grade paint at a specification price: Crown Trade Sandtex Ultra
Never buy a tin without first checking the tinted price — brilliant white headline prices can be misleading, particularly at Farrow & Ball and Sandtex Trade.

Frequently asked questions
What is the best exterior paint brand in the UK in 2026?
For most UK homeowners, Dulux Weathershield Smooth Masonry offers the best combination of availability, proven durability and — uniquely — a Lifetime Guarantee when registered within six months. Professional decorators more often specify Sandtex Trade 365 for its 20-year durability claim and cold-weather application.
How much does a 5L tin of exterior masonry paint cost in 2026?
Prices in April 2026 range from around £32 for Crown Trade Sandtex Ultra Smooth up to £128 for Farrow & Ball Exterior Masonry, per 5L. Most mainstream trade options (Dulux Weathershield, Sandtex 365, Leyland Truguard) sit between £35 and £58 per 5L tin.
Which exterior paint lasts the longest?
Sandtex Trade 365 and Wethertex PP77 both carry up to 20-year durability claims from their manufacturers. Dulux Weathershield is backed by a Lifetime Guarantee (with registration) which in practice often outperforms the numerical claims on competitors.
Can I use Farrow & Ball on a listed building?
Yes, and it is a common specification for listed and conservation-area properties because of the historically accurate colour range. However, always check with your local conservation officer before painting the exterior of a listed building — consent may be required if the colour change alters the building's character.
