By Graham Wood

Absolutely the best masonry cream I have used. Does not alter the original substrate whatsoever. Obviously not been able to confirm the 25 years protection but the elevations we applied it to show no signs of water absorption and have no complaints about further water ingress which was previously a common occurrence.

By J Morgan

I applied the masonry cream product to the side of our house which is south facing and suffers from driving wind and rain. Although its early days we had a downpour overnight and the bricks are dry so looking good and working as it says. Excellent.

Product Description

Climashield Masonry Protection Cream is a VOC free, water based, protective treatment brick waterproofer, specially formulated to create strong waterproofing properties on brickwork, masonry and render. The deeply penetrating Masonry Cream is a very effective damp proofer and brick sealer that forms a strong barrier against penetrating damp.

  • Highly-effective brick waterproofer
  • Dry, "Invisible" Finish
  • Leaves Walls Breathable
  • Coverage ratio: 5 m per litre is recommended on standard brickwork
  • Can be painted over with a specialist silicate-based masonry paint (such as Seciltek & Earthborn paints) once the Masonry Cream has sufficiently cured (7 days recommended).  
  • Can be used on softwood,such as pine. Its penetration is not as good as on Masonry but it does work as a water repellent. Not recommended for hardwood, such as oak, teak & mahogany.
  • The substrate must be dry prior to application, otherwise this will present a barrier to the Masonry Cream soaking into the surface.
  • Minimum application temperature: 10C
  • The waterproofing masonry sealer will last up to 25 years
  • NOT suitable for use over K Rend or Monocouche render systems

In a storm dry walls are essential if you want to avoid water ingress and long term damp. The Masonry Protection Cream provides long lasting protection from water penetration and the spread of damp in masonry and brickwork by filling the porous voids within the substrate without blocking them. This allows the masonry to release trapped moisture and to 'breathe', preventing moisture build up. This effective brick waterproofer can last up to 25 years and help to prevent the spread of penetrating damp.

Unlike waterproof paints and waterproof coatings that are available in DIY stores our protective cream is far more effective and lasts much longer. It will also retain the original dry appearance of the substrate so it is ideally suited for application to brickwork, stonework and most forms of unprotected masonry.

This highly effective damp proofing system will also provide a highly effective additional barrier to flooding as part of any existing flood protection system.

Dry damp proof walls will also increase the thermal efficiency of a property. This can produce energy savings from an average of 6% to as much as 29%, if used in conjunction with other green deal systems.


Viscous masonry cream based on Advanced Silane/Siloxane chemistry.

For best results, one heavy application of ClimashieldTM Masonry Cream on standard brickwork at 5m per litre is recommended. On dense, less absorbent brickwork or render, coverage of the brick waterproofer can be increased by up to 10m per litre.

The substrate must be dry prior to application, otherwise this will present a barrier to the Masonry Cream soaking into the surface. Minimum application temperature: 10C. Store the product in a cool, dark place to prevent contamination by bacteria or fungal spores carried by air. Only open containers to remove the amount of product required and then close the lid once the product has been taken out. Once the containers have been opened, use up the complete contents as quickly as possible.

Can be applied by roller or paint brush. Due to its high viscosity, a simple, drip and run free application is possible. In general, only one heavy application is required. The cream will penetrate and absorb into the substrate within 30 minutes to several hours, depending on surface porosity. Once dry, the brickwork or masonry will be left with a dry/invisible finish.

Product FAQs

Q: Hello, I wonder if you can help please. My house is brick built and was painted before I bought it in 1987. Over the years it has been painted repeatedly because the paint couldn't be removed. Now, it's reached the point where I really don't want to paint it again. Would it work if I used the waterproofing cream over the top of the raggedy looking paint? I'm now in my 70s and don't feel inclined to do much more with this house. Thank you for any advice you can offer.

Helen Crowther

A: The masonry protection cream is highly effective, but for it to be effective, it needs to penetrate into the brick work. The paint will stop it penetrating correctly, we would suggest trying a sample 1st. Hope that helps.

Response from Jacob

Q: Hi, I have a wall which has an efflorescence on it from due to the roofing above the parapet on a flat roof having been installed incorrectly. I have now replaced the roof lining and it is dry. The efflorescence is a general white appearance rather than there being any chalky deposits. Can I paint the cream on top of this, or do the bricks need to be cleaned before? My issue is that I have an aluminium canopy below the wall in question and am concerned an efflorescence cleaner would damage its protective paintwork. Thanks, Simon.


A: Its always best to try and remove any efflorescence before you try to seal, but in some cases this is not possible. You should be able to apply the masonry protection cream but try to brush off as much efflorecence first before applying the cream. The efflorescence remover is an acid based cleaner so you need to take care around areas that you think it could damage.

Andy Archer

A: Masonry Cream is generally recognised as the best way to prevent moisture ingress on walls. Our 'How To'YouTube guides explains how the product works (samples are available for testing) Hope that helps.
