“ The primer is just as important , if not more , then the topcoat . In many cases consumers tend to go for economical products to be used as primers , then follow with a premium option as a topcoat . However , your paint will only be as strong as the weakest link ,” adds Kohlhofer .
3 . Dealing with damp
Dulux PrePaint Dampshield can be used on lower wall areas , after they have been repaired with the cementitious mixture , to protect against paint peeling , efflorescence , and mold caused by rising damp .
If damp is a major issue , the top horizontal parts of the wall can be waterproofed using Dulux Rainshield to prevent moisture ingress from ponding water , also known as falling damp . Lastly , Dulux Weatherguard can be applied for a tough durable and water-resistant finish . The unique texture will help to hide minor plaster imperfections and is formulated with Maxiflex™ - to provide lasting elasticity to cover hairline cracks .
Always make sure that you wait for the preparation materials and paint products to dry properly before over coating as this can influence the performance of the paint system adds Rudi .

Ideal time to paint exterior walls
A general rule of thumb is to paint when rain is not forecasted , temperatures are between 10-35 ° C , humidity is not exceeding 85 % OR when it is > 2 ° C above dew point .
“ In winter avoid painting too early in the morning or too late in the afternoon as it is normally too cold and can influence the drying , curing and film formation . In Summer , do not apply when it is too hot or if the surface is too hot e . g . roofs , as it can force dry the paint that can again influence film formation leading to cracking or peeling paint ,” advises Kohlhofer .

Considerations when selecting exterior paint
Exterior elements such as UV , rain and pollution are harsh and will truly test the paint , therefore make sure you choose a premium product like Dulux Weatherguard for premium resistance and protection . Kohlhofer explains that all colours fade at different rates . Natural earthy type colours generally produce the best UV / fade resistance compared to bright or more spontaneous colours such as bright reds and yellows etc . Darker colours also tend to fade at a quicker rate due to absorbing more heat and putting additional stress on the paint coating .
Now that you have the expert advice , that “ home refresh ” will yield even better results .
