Damp proof and painting process – house walls

Preparation before damp proofing homes and painting homes is vitally important. To start damp proofing your walls, or painting of  house  (building) walls, a high pressure hydro wash of the walls thoroughly to remove any loose paint, bird droppings and any other dirt.  Where wall creepers are present, they should be removed. It may be necessary to grind the walls.


Painting and damp proofing double storey houses or buildings:

On double storey houses, and in hard to reach places it may be necessary to erect scaffolding.



Before wall painting or wall damp proofing, all cracks in the walls need to be opened up and repaired. We repair wall cracks by either the use of a patching compound or by re-plastering a crack. *Please note that some cracks are caused by structural defects/movement.



All window sills are included in the wall production procedure and can either be matched to the roof or the walls. All other areas that may come into contact with dropping paint  during the wall painting process, are masked. Drip sheets are used to avoid unsightly drops of paint on paving, etc.



In areas where there is bad plaster this plaster must be cleaned out, the relevant areas need to be re-plastered.



Where we encounter damp areas, one damp proofing product used could be Coprox.



This product prevents damp from within the wall reaching our wall coating.

*Please note that we cannot stop rising damp in house or boundary walls, we can only delay its effects on our coating. In most cases the combination of our wall coating and Coprox stops the damp problem altogether.

Where we re-plaster and repair cracks, we also skim the area to try blend the wall repair into the existing texture as much as possible.



Preparation of the parapet walls: All parapet walls need to be inspected, and if necessary repaired. Thereafter a coat of latex compound is applied to seal the parapet. Often it may be necessary to apply a fibre glass membrane.



Before coating commences colour samples can be applied to the walls should the client choose a tone darker or lighter than our standard colours.

The sealer coat is applied to the walls. This prepares the walls for our coating product.



Shown here is the application of the first coat of our Acrylic sheen coating.



After second coat of Acrylic sheen coating is applied to finish.



In bad areas, and areas with lots of fine, hairline cracks and variable plaster texture a base coating of our Acrylic ripple coating is applied. Due to it’s extreme thickness and elasticity it is a perfect coating to help hide unsightly defects.


As acrylic ripple coating is used as a undercoat only, a finishing coat of Acrylic sheen coating is applied.



The final product after second coat of Acrylic wall coating is applied
