Firstly, check the outside of the building for rainwater penetration - if the walls are absorbing moisture apply a water repellent - UltraProof

UltraProof- the best treatment for external masonry, brick, stone and render. Applied in a single flood brush or spray coat, it forms an invisible (to the naked eye) layer just below the surface of the masonry, repelling moisture but allowing the wall to breathe through its micro-pores.

UltraProof benefits are as follows;

1. Water based
2. Non-flanmmable
3. Ultra low odour
4. Only need one coat for full protection
5. Brush or spray on
6. Clean glass with a damp cloth
7. Does not deteriorate if used on new pointing or render (unlike some silicones)
8. Breathes
9. Non-staining

Can also be used as a Primer/Sealer on damp floors, and to eliminate dusting from concrete floors.

Available in 5 litre and 25 litre cans, ready to use

Secondly, check the inside of the building for evidence of 'salts' in the lower 1 metre of the outside walls - if the walls are suffering from rising dampness you may need a new Damp Proof Course - we can give you the name of a Qualified Dampness Surveyor in your area.

If necessary, removed all plaster to at least 1.2 metres above floor level and inject a new DPC using Quick Cream DPC.

Quick Cream DPC - the best cream based emulsion for creating an injected DPC. No odour, no staining, non flammable.

Available in 400cc, 1000cc tubes and 3 litre tubs.

Thirdly, check the plaster for signs of white, fluffy salts - efflorescence - this indicates wetting and drying-out. If you have cured the source of the moisture and the plaster is still firm and not hollow, you could now treat the plaster with Salt Neutraliser

Salt Neutraliser - the best treatment for 'salty' plaster, when the cause is wetting and drying-out.

Salt Neutraliser benefits are as follows;

1. Water based
2. Non-flanmmable
3. Ultra low odour
4. Only need one coat for full protection
5. Brush or spray on
6. Breathes
7. Non-staining

This wall should be stripped back to bare masonry and treated with Salt Neutraliser

Mould growth is caused by Condensation forming on the surface or inside the building material

Condensation is caused by high levels of moisture in the air condensing on the coldest surfaces in the room, often at night when the temperature falls

Surfaces will be colder if they are damp - rising and penetrating dampness, blocked wall cavities or lack of them, can all increase dampness

Dampness can be caused by common defects, like blocked gutters overflowing, poor pointing, cracked external render.
