Our wall stabilising solution stabilises friable mortar, hardens surfaces which have "gone soft" due to weathering and allows you to paint straight after re-rendering or pointing in preparation for the application of "Weatherflex". Improves adhesion and depth of colour finish.
A high performance, breathable masonry coating, developed over three decades in the challenging environment of the Lake District. Professional and amateur users alike simply love applying Weatherflex because it covers beautifully on brick, stone and rendered surfaces.
Whatever the Weather
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:
Flexibility – The elasticity of the formulation imparts superior crack-bridging qualities during application and once cured, allows the waterproof exterior coating to move with the expansion and contraction of the substrate. This characteristic absorbs seasonal extremes of temperature and prevents unsightly flaking or delamination, providing better performance.
Durability – The materials which make up Weatherflex are carefully selected for their long-term performance, to create a waterproof masonry paint that performs in extreme conditions.
Breathability – Microporous finish keeps the water out, whilst allowing the substrate to “breathe” or evaporate moisture.
From day one, Weatherflex was focussed on performance, largely 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 hand-made product, being manufactured in modest batch sizes but the 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 spawned it. From the Welsh valleys to the Outer Hebrides, people depend on Weatherflex waterproof paint, whatever the weather.

How does it work?
Weatherflex is made to perform in nature’s extremes but what does that actually mean for the majority of urban situations? In a word reliability. Manufactured using only the finest materials, including superior grade polymers and U.V stable pigments, it is a product of extremes which will last longer, retain colour better, hold back damp and leave you free to think about more important things.
Weatherflex protects thousands of building exteriors including:
• Townhouses, villas, terraces and bungalows
• Barn conversions
• Stone built cottages
• Commercial & industrial
• Coastal homes
Interior applications include:
• Domestic garages
• Commercial garages
• Commercial letting units
• Warehouses & Manufacturing
• Milking parlours (washable)
• Kennels (washable)
• Bars & restaurants
Being a water-based formulation, it is low odour and non-toxic which makes 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 held up us a must-have feature in exterior coatings, and it is true that the ability to allow latent moisture to escape freely from the substrate is important. However, our field trials revealed that some exterior coatings push this line to the point where water-proofing is compromised. As with so many things, it is a matter of getting the balance right, and this is where we believe Weatherflex scores with ideal levels of micro-porosity, coupled 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.
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
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
Solution to harden the surface and improve the adhesion of the Weatherflex coating
Stir thoroughly before use. Typical coverage is 8 to 10 sq m / litre. On textured or porous surfaces this may vary down to approximately (5 to 6 sq m / litre).
Apply by brush, premium masonry roller or by *high pressure airless sprayer*(*SMOOTH ONLY*)
For best results a minimum of 2 x coats should be applied. Further coats may be required to obliterate strong background colours or surface staining. If using a roller, apply in broad even sweeps, overlapping to ensure full coverage. Detailing around window reveals and doors should be ideally be “cut in” with a two inch premium brush or similar.
If spray applying *(SMOOTH ONLY) we recommend using or hiring a premium brand (Graco/Wagner) high pressure airless sprayer.
Time spent masking off windows and other vulnerable areas will be repaid with fast application times and crisp, sharp lines.
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
As always we recommend that you read the Technical Data Sheet & Safety Data Sheet thoroughly before commencing any work. If in doubt please call us for advice, we are here to help.
Remove loose paint
Remove all existing loose paint either chemically with paint stripper or with a wire brush and scraper to make sure that you have a sound surface onto which to apply the "Weatherflex". It is not necessary to remove all existing paint – that which is still well bonded to the surface will normally provide an adequate base for "Weatherflex".
Neutralise Moss & Mould
Where green mould, lichens and moss have taken hold, spray or sponge thoroughly with Kingfisher "Bio Wash" to kill off the visible "green stuff" and also the invisible roots and spores which are embedded in the substrate. This is very important and will prevent re-growth underneath your new coating.
"Make Good" Pointing
Carefully examine the mortar joints for signs of decay and rake out any crumbly areas and re-point adding Kingfisher "Pointing Solution" to the mix for waterproofing, flexibility and adhesion. Pay special attention to repair of chimney stacks as these are a frequent source of moisture ingress. Phone us if in doubt.
Repair Weathered Bricks or Stone
If there are any "blown" brick faces or stones, these can be “faced up” as follows:
a. Priming Mix
In a bucket mix ONE part sharp sand, ONE part ordinary cement with neat "Pointing Solution". This should be paddle mixed with a drill (400 to 600 rpm) until a "yoghurt consistency" is achieved. You then brush or stipple this grey primer onto the area with a masonry brush or similar. Leave this for around 20 to 30 minutes.
b. Repair Mix
Mix up a stiff repair render of 1 part cement to 4 parts sand mixed with "Pointing Solution" and a little water. It is important to apply the repair render within half an hour of the primer mix to ensure "continuity of key". This method avoids the usual shrinkage cracks and "falling out".
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. The same treatment should be used for "dusting" surfaces and flaking paint which cannot be adequately removed by wire brushing.
"Weatherflex Stabilising Solution" must be applied to any new pointing or re-facing repairs prior to coating with "Weatherflex" to prevent the alkalinity in the mortar from discolouring the paint (because although mortar hardens within 24 hours, it takes up to two months for full chemical cure!). Where the wall substrate is non-porous in nature (e.g. engineering bricks or granite stone) you should apply "Weatherflex Stabilising Solution" to improve adhesion. If in doubt a small test area of both stabilising solution and paint should be applied to check compatibility with the surface and if possible left to weather. Note: This is especially important if there is a possibility that the surface might previously have been treated with a clear water repellent or similar.
Apply the Weatherflex ™
"Weatherflex" requires 2 coats and can be applied by brush or roller. Apply with broad, even strokes and avoid "loading" the brush or roller, especially on the first coat. It can also be sprayed with some DIY sprayers but for high pressure spraying our "Kolourseal wall coating" range is specifically formulated for professional contractors. It is recommended to coat one elevation at a time and check the batch numbers, ensuring that tubs from the same batch number are matched up for the top coat or at least per elevation. Do not apply in temperatures below 8 °C. Always buy a tester pot to check the colour suitability BEFORE ordering the full size container(s).
The coating should be applied using brush or roller, aiming for a coverage of 8-10 sq mtr/litre for smooth surfaces and 4-6 sq mtr/litre on rough surfaces. Do not use outside when conditions are below 5 deg C over 24 hours or if rain is imminent. The paint will be touch dry in approx 2 hours, allow 4-6 hours between coats. Clean all brushes and rollers immediately after use in warm soapy water.
What is the estimated lifespan for "Weatherflex"?
If the surface is prepared correctly in accordance with the data sheet and regularly maintained, "Weatherflex" will last for 15 years.
Does the surface need to be dry to apply "Weatherflex"?
The drier the better to ensure good adhesion to the substrate.
Do I need to use a primer before applying "Weatherflex"?
It depends on the condition of the surface to be painted. "Virgin" unpainted surfaces should be primed with "Weatherflex Stabilising Solution" to improve the coverage, adhesion and depth of colour of the "Weatherflex" paint on existing painted surfaces, spot apply "Weatherflex Stabilising Solution" to improve adhesion on areas where the old paint has flaked off during surface prep.
What is the minimum temperature for applying "Weatherflex"?
"Weatherflex" should not be applied at temperatures below 6 deg C or in damp I humid conditions. In winter especially always allow sufficient time (at least 4 hours) for the paint to cure before the evening dew point.
I am painting a wet dashed wall, should I use the "WeatherfIex" Textured or Smooth?
Textured "Weatherflex" is normally used to give a decorative sand effect to smooth or plain surfaces. Use "smooth" on pebble dash or textured renders.
This paint is superior!
This paint is superior to some offered by the DIY chains. Would buy again. Very good quality paint- Highly recommend.
