Satin paints require a bit more care during application in order to avoid lap marks. As with interior painting, it is important to keep a wet edge during application. It is important that satin paints be thoroughly mixed before application to keep the resins and pigments in uniform ratio throughout the can. Satin paints should be mixed just before every painting session.
Small random-orbit or pad sanders make this job go faster. (Wallis first covers these boundaries with Synkoloid patching compound so no edge is visible after sanding.) As shown, you want to make sure that there is a feathered, smooth transition from exposed wood to old paint. For areas that might get close scrutiny, you can follow up with a 100- or 120-grit rubdown to erase any scratches.
#4 You have to be very careful about choosing the accessories. You should find something resourceful, easy-to-use and more effective. As an example, you should find a suitable extension pole instead of the ladders. These extension poles will help you paint the surface from a closer distance and will allow painting the surface more precisely. Also, you should find painting grids instead of the popular trays. Before you start, you should arrange all the items you might need while painting.
