or mould is present treat it with a bleach solution and rinse off . Remember to allow the surface to dry completely again . Ensure the surface is free of all loose material . Rake open non-structural plaster cracks and clean out the crack with a brush . Fill the crack with an appropriate filling compound . Prime the crack before and after filling .
“ From the outset you need to pick the right weather for any exterior painting job : do not even think of painting in rainy weather .”
Structural cracks might need some added attention such as re-enforcement or the creation / insertion of a construction joint .
In some cases , the previous paint might have powdered due to natural weathering and therefore it will be required to apply a binding coat such as a bonding liquid ( this is generally applied prior to filling ).
Once the surface is adequately prepared , primed ( if needed ), and stable , finish with a minimum of two coats of the correct topcoat to ensure a solid , closed , uniform and long-lasting finish .
