Do you own a house with unpainted brick or stone exterior walls? Does your home suffer from damp or condensation? Are the brick pointing mortar joints falling out? Do you have crumbling or loose bricks? Is your home always cold, even with the heating switched on?

If you have said “yes” to ANY of the above questions then this impermeable exterior coating we offer could be what your house needs.

Bricks are made to provide some form of weatherproofing for houses but over time the weather erodes this and the bricks start to let in water and starts a knock on effect of deterioration.

If left unchecked this causes untold damage to the house itself.

There IS a solution to cure this.

A demonstration of the coating

We demonstrated this by treating this house brick (below) and waited just one day.

We then poured water on to it and this is what happened!

The compound forms a silicone barrier in the capillary channels (the billions of microscopic holes or voids within your walls that allow moisture to pass into the house), and leaves no sign of discolouration which helps to keep the surface of the walls clean.


CURES PENETRATING DAMP clearshield silicone wall coating -on-brick waterproof

Weatherproofing your outside walls without changing the look!

The fact that this coating makes no visible change to the wall, means that it can be applied (by us) on houses and buildings where, if the wall surface was painted, it would ruin the look of the house.

Once it is applied, using 2 coats, any rainwater will run off without soaking into the building. It is fully breathable and does NOT “seal up” the house.


Application of NPA clear wall coating

  • We 1st clean the external walls, getting rid of dirt, mould, moss, flaky paint, algae, traffic or industrial grime, pollution etc.
  • We then expertly check the building for defects such as loose or missing pointing or mortar joints, cracks and  hollow render, crumbling bricks etc., and carry out the required repairs (if applicable) to the external walls.
  • We then spray apply  2 coats of the waterproof wall coating product as required.
  • Then our teams clean up and put all tools and equipment back in the van and you would never know a work team had been to your home!

….and once it starts to rain, you will see the water “bead” off the wall, keeping you nice and dry inside, and more importantly, free of penetrating damp!
