Weatherflex Textured Premium Masonry Paint

Best UK Exterior Masonry Paint For All Weather Conditions

Available in a stunning range of contemporary colours from our “Lakes & Fells' collection, Weatherflex is a superior, matt-finish exterior masonry paint suitable for application to almost all types of masonry and mineral-based surfaces.   It has three key features:  

What Makes Weatherflex The Best Exterior Masonry Paint in the UK

Flexibility – The elasticity of the formulation imparts superior crack-bridging properties during application and, once cured, allows the waterproof exterior coating to move with the substrate's expansion and contraction.  This characteristic absorbs seasonal temperature extremes and prevents unsightly flaking or delamination, resulting in improved performance.

Durability – The materials that make up Weatherflex are carefully selected for their long-term performance, creating a waterproof masonry paint that performs in extreme conditions.   

Breathability – The microporous finish keeps water out while allowing the substrate to “breathe” and evaporate moisture.

From day one, Weatherflex was focused on performance, mainly because it was part of a portfolio of Kingfisher products being used in the growing barn conversion movement sweeping our home county of Cumbria, as well as further afield to the neighbouring Dales.  If the Kingfisher damp proofing and tanking systems had to be first class to dry out a century-old cow byre, then the exterior coating had to be even classier!

Today, Weatherflex is still a relatively handmade product, manufactured in modest batch sizes, but improvements have never stopped.  As a small, independent manufacturer, we have the luxury of prioritising quality and innovation over cost.  Accordingly, our reputation has grown organically to the point where Weatherflex has built a loyal following far beyond the rainy Fells that gave rise to it.  From the Welsh valleys to the Outer Hebrides, people depend on Weatherflex waterproof paint, whatever the weather.

How does it work?

Weatherflex is designed to withstand nature’s extremes, but what does that mean for the majority of urban situations?   In a word, reliability.  Manufactured using only the finest materials, including superior-grade polymers and UV-stable pigments, it is a product of extremes that will last longer, retain its colour better, and keep out damp, leaving you free to think about more important things.   

Weatherflex protects thousands of building exteriors, including:

•    Townhouses, villas, terraces and bungalows
•    Lighthouses
•    Barn conversions
•    Stone-built cottages
•    Commercial & industrial
•    Churches
•    Coastal homes
•    Shopfronts
•    Restaurants

Interior applications include:

•    Domestic garages
•    Commercial garages
•    Showrooms
•    Gymnasia
•    Commercial letting units
•    Warehouses & Manufacturing
•    Milking parlours (washable)
•    Kennels (washable)
•    Bars & restaurants

Being a water-based formulation, it has a low odour and is non-toxic, making it easy to use both internally and externally.  When you open the bucket, it has a reassuringly thick, creamy consistency, which gives the first clue to the high solids content.  Load your brush or roller and Weatherflex covers effortlessly, showcasing the adhesive quality of the high-bond polymer.  As an exterior waterproof paint, it is peerless in performance but is equally at home providing a durable interior finish that can be cleaned or washed down.  

The flexibility of the cured finish is also derived from our choice of polymer, which gives the product its exceptional “flex” or elasticity (over 100%).   This also provides the non-shrink characteristics, which fill and cover hairline cracks so effectively.

“Breathability” is often regarded as a must-have feature in exterior coatings, and indeed, the ability to allow latent moisture to escape freely from the substrate is essential.  However, our field trials revealed that some exterior coatings push this line to the point where waterproofing is compromised.  As with many things, it is a matter of striking the right balance, and this is where we believe Weatherflex excels, offering ideal levels of micro-porosity combined with weather protection that prevents moisture ingress in the first place.

How to use Weatherflex

Surfaces should be generally clean, dry and free of grease, oil, flaking paint and other contaminants.

Surface Preparation
1)  Cleaning:  Wash away loose dirt using clean water with a scrubbing brush and mild detergent as required, and allow the surface to dry
2) Remove loose paint:  Either chemically with paint stripper, grit blasting or with a wire brush and scraper. It is not necessary to remove all existing paint, just the loose paint
3) Neutralise Moss & Mould: Where green mould, lichens and moss have taken hold, spray or sponge thoroughly with Kingfisher Bio Wash to neutralise
4) Make good pointing & render damage: Carefully examine the mortar joints or render for signs of decay and rake out any crumbly areas, then re-point, adding Kingfisher Pointing Solution to the mix for waterproofing, flexibility and adhesion
5) Stabilising & Priming: Where stone, brick or mortar may be slightly friable or “soft”, such surfaces should be primed with Weatherflex Stabilising Solution to harden the surface and improve the adhesion of the Weatherflex coating

Application
Please ensure that you stir thoroughly before use.  Typical coverage is 5 to 6 sq m/litre on textured and porous surfaces, and 8 to 10 sq m/litre on smooth surfaces.

For best results, a minimum of 2 coats should be applied.   Further coats may be required to obliterate intense background colours or surface staining. If using a roller, apply in broad, even sweeps, overlapping to ensure complete coverage.    Detailing around window reveals and doors should ideally be “cut in” with a two-inch premium brush or a similar tool.  

Time spent masking off windows and other vulnerable areas will be repaid with fast application times and crisp, sharp lines.

IMPORTANT!

a) Do not apply in temperatures below 7 °C or if wall surface temperature exceeds 32 °C.
b) Do not apply in wet conditions or if rain is expected within 24 hours of application
. c) Do not apply to damp surfaces
. d) Where salt contamination is detected, pre-treat with Kingfisher Eco-Brick Cleaner

A 5-litre bucket of Weatherflex covers 25-30m² with the recommended two coats. On textured and porous surfaces, it provides coverage of 5-6m² per litre, while on smoother surfaces it may cover considerably further (8-10m² per litre). This excellent coverage makes Weatherflex more economical than standard masonry paints that require frequent repainting.

For best results, a minimum of 2 coats of Weatherflex should be applied. Further coats may be required to obliterate strong background colours or surface staining. Allow 2-4 hours between coats (depending on temperature and atmospheric conditions). This two-coat application ensures optimal waterproofing, durability, and a uniform finish.

Do not apply in temperatures below 7°C or if the wall surface temperature exceeds 32°C. Do not apply in wet weather or if rain is expected within 24 hours of the final coat. In winter, when temperatures are lower and days are shorter, try not to apply Weatherflex later than 1:00pm as it needs time to cure before the onset of the evening dew point, which stops the curing process and leaves it vulnerable to frost damage.

Where stone, brick or mortar may be slightly friable or "soft", such surfaces should be primed with Weatherflex Stabilising Solution to harden the surface and improve the adhesion of the Weatherflex coating. The same treatment should be used for "dusting" surfaces and flaking paint, which cannot be adequately removed by wire brushing. For non-porous substrates, such as engineering bricks, priming enhances adhesion and ensures a long-lasting finish.

Weatherflex "effortlessly outperforms standard masonry paints" thanks to three key features: flexibility, with elasticity that prevents flaking and delamination; durability, achieved through carefully selected materials for long-term performance in extreme conditions; and breathability, provided by a microporous finish that keeps water out while allowing the substrate to breathe. These qualities result in a 15-year lifespan compared to standard masonry paints that typically require repainting every 5-7 years.

Yes, Weatherflex is suitable for application to "brick, stone, concrete block, concrete, render, pebbledash and more." It provides exceptional protection on domestic, commercial, agricultural and industrial buildings, even where lateral penetrating damp has been an issue. Common applications include exterior brickwork, stonework, renders (including the renovation of self-coloured renders), and pebble dash. This versatility makes it an ideal solution for nearly all UK properties.

Weatherflex is a damp-proof exterior wall paint that stops rainwater penetration while remaining breathable. This helps reduce "internal condensation problems by warming external walls." The flexibility of the coating also effectively fills hairline cracks, which limits damage from the freeze-thaw cycle—a common cause of water ingress in UK properties. This dual-action approach prevents water from entering while allowing existing moisture to escape.
