Kingfisher's premium grade breathable Weatherflex Masonry Paints have been protecting Lakeland homes in all seasons for over twenty years. Our masonry waterproofing paint was at first developed as a flexible, waterproof coating, sympathetic to our unique Cumbrian fell stone. Due to its quality, Weatherflex has earned a national reputation for endurance, weather protection and depth of colour.
Exterior walls are regularly being exposed to the British climate so they can look untidy and unloved. For long term quality, our Smooth Masonry Paint will ensure your exterior surfaces will look outstanding for many years. The protection that this masonry waterproofing paint provides is second to none and will guarantee to give you fantastic coverage. It is very easy to apply by brush or roller.
Flexible Exterior Masonry Paint
There is nothing as effective at waterproofing masonry that our Flexible Exterior Masonry paint. Our broad expertise in the field of structural waterproofing has always been heavily influenced by our Lakeland location. This has been so instrumental in the continuous testing and improvement of our products. However, our flexible exterior masonry paint, in particular, has benefitted from years of development in the harshest of nature's proving grounds.
Our latest range of high performance Exterior Masonry Paints, therefore, represents a culmination of performance progress. Our wide range of flexible exterior masonry paint features new colours inspired by the Lakeland landscape. The demanding climate and raw beauty have been so integral to the development of the Weatherflex range. From the coastal sands of Silverdale to the depths of Wastwater, there are colours to inspire any project.
Please Note: Computer screens and printers do not render colour consistently. Our “Lakes and Fells Collection” colours are made to order (Excepting White & Magnolia) so ordering a tester pot is highly recommended to check your colour preference accurately, before making your final choice.

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.

Kingfisher Weatherflex Smooth
Previously used a “well known” brand which has been recoated twice in 5 years! Ordered weatherflex as a result of reviews and absolutely chuffed with the results. Lovely paint, good coverage (even on new render) and looks great. Colours are pretty true to the charts too. Brilliant service and very friendly and efficient staff. Thanks.
