Lapping

Have you noticed that there are areas of denser colour or higher gloss where wet and dry layers overlap during painting?

Possible Cause

This is caused by not maintaining a ‘wet edge’ while painting.

 

Solution

Invest in a quality synthetic roller sleeve (5mm nap for gloss & semi gloss and 12mm nap for low sheen and flat finish). Do not over load rollers & heavily apply the product or over-spread & work out; which can compromise the finish in both cases.

 

Prevention

To maintain a wet edge, apply your paint towards the unpainted area and then back into the just-painted surface. Brushing from wet to dry, rather than the other way around will help produce a smooth, uniform appearance. It’s also wise to minimise the area being painted and plan for interruptions at a natural break, such as a window, door or corner.
