Now that Autumn has returned we are seeing a lot of enquiries concerning damp patches on soft porous stone walls caused by heavy rain, especially wind driven rain. More often than not on the south/south westerly aspect of the house which does tend to get the majority of the strong winds.

..

A lot of these stone properties are very attractive looking and the owners quite rightly do not want to render over the stone or alter the colour and texture of the natural stone by painting over with a waterproof exterior paint.  Now however, there is a way of stopping the water from soaking through the stone without compromising the look of the walls.

..

There is a superb colourless coating that can be applied to the stone and which will seep into the core without leaving any visible signs on the face of the wall. Whats more the treatment is also backed by AXA with a 10 year guarantee against water penetration.

..

We also suggest that to cover all the bases a full appraisal is made of the condition of the mortar pointing and of the window and door sealants to rule out water entering via either of these areas. Any remedial action to the pointing or windows is carried out before the application of the clear water repellant.

..

Crucial to the success of any system is that the coating must be able to act like a human breathable skin by allowing moisture in the wall to escape to the outside whilst at the same time resisting water penetration into the stone itself.
