Just about nothing can make an interior space look clean and inviting more than a new coat of paint. In order to get good coverage, here are tips to get the job done right the first time. One reason paint doesn’t cover well is because it was thinned too much. Most recently purchased paint does not need any thinning. If it does, however, follow the manufacturer’s instructions.
Another reason paint doesn’t cover well is because the substrate is extremely porous. New drywall is an example of such a surface. Other troublesome circumstances are painting over a glossy or semi-gloss paint or a lighter color over a darker color. In these circumstances, use a high-quality primer to get the best adhesion.
Painting with latex paint over an oil-based paint also requires a primer, even if is a latex one. Primers have chemical properties to help the topcoat adhere well to the substrate. Professional painters use only quality paint from tried-and true paint manufacturers because cheap, low-quality paint won’t cover well.
Always start with a clean, dry substrate. Fix holes and cracks with the appropriate caulk or plaster compound and allow the patches to dry. Use rollers and brushes that are appropriate for the paint (latex- or oil-based) and surface (smooth, semi-smooth or textured). Brushes and rollers of good quality give the best finish.
Before starting to paint, stir the paint well because the contents can separate. Stir it from time-to-time when painting too. Buy enough paint for the job so overspreading, which causes poor hiding, isn’t necessary.
Make sure the paint on the roller is evenly distributed. Paint should not be dripping from the roller when painting begins. After cutting in a top border that’s 3 inches x 3 inches with a brush or roller, work with brush in sections that are 36 inches x 36 inches.
Begin at top and work in sections that are shaped like W’s or V’s. Fill each section in while the paint is still wet. When almost all the paint is off the roller, go over the newly painted section without lifting the roller up. Overlap the edges of the sections.
Using the proper preparation techniques and quality materials are the keys to eliminating paint with poor hiding, These products are available to give homes and buildings a great paint job that will garner satisfaction for owners and admiration from visitors.
