Roof & Wall Waterproofing Services


A 5 year, 10 year or 15 year WONDERCOAT guarantee is issued on the completion of all coating work completed by ourselves. Based on general world wide experience on similar products, it is reasonable to expect a total life span of 15 - 20 years.

Material Properties


Whilst Wondercoat cures to a very hard surface, it simultaneously maintains a carefully pre-formulated elasticity in order that it may bridge subsequently hair-line cracking in the substrate.

Material Properties

Water resistance

Wondercoat acts as an osmotic membrane, whilst being completely waterproof on the outside, it allows any dampness from within the wall to escape as vapour.

Material Properties


Each ingredient is carefully scrutinised, tested and approved prior to mixing, in order to ensure the highest quality for our rigorous and diverse climatic conditions.
Wondercoat has a one way action by allowing any moisture, which may be in the substrate to “breath” through the treated surface and through the Permatex coating.

Step One

Canvas ground sheets are placed all the way around the property to ensure maximum cleanliness and as little mess as possible.

Step Two

All areas not to be coated will be masked off with heavy duty masking paper and masking tape to ensure neatness of application.

Step Three

All painted wall areas will be thoroughly cleaned down mechanically by means of electrically driven angle grinder using carborundum discs or wire-cupped brushes where necessary.

Step Four

All cracks are repaired with elasticized bound filler (WONDERFLEX) and coated with Waterproof (Membrane free system). A fiberglass membrane will be used to repair all major cracks.

Step Five

Contaminated plaster will be chopped off and re-plastered.

Step Six

Pigmented plaster primer will be applied to weather-proof the walls and also neutralized and alkali (Lime) acids or salts present on surface.

Step Seven

A Membrane Free elasticized resin bound waterproofing emulsion is used to weatherproof exposed parapet walls.

Step Eight

Professional supervision on site at all times.
