An airless sprayer is the fastest method for painting interior walls, but the resulting overspray makes it impracticable for painting a single wall. You may also use a roller and brush instead. A roller is best for covering large areas of wall, while a brush is better for getting into tight spaces and painting around fixtures. Although rolling a wall requires no special skills, certain pointers may make the process go more quickly.
Tape With Discretion
The process of taping off trim, woodwork, and windows may be tedious and potentially damaging to freshly painted surfaces. If you’re willing to carefully cut in, you can skip taping the vertical and above boundaries. Making a straight line with your paintbrush isn’t too difficult, provided you have a steady hand and an attentive eye. This is particularly true if you use a high-quality brush with tapered bristles. Make sure the walls are ready to go.
Preparing the walls before painting will save you time and effort. This involves etching the surface so the paint adheres and ensuring sure there are no specks of old paint or dried joint compound that will ruin the finish. The best approach to degloss old paint and remove grease, crayon stains, and other filth is to wash the wall with a solution of 1 cup trisodium phosphate or an equivalent detergent to a gallon of warm water. Use a thin coat of lightweight wall spackling compound to patch up any holes you see. It dries rapidly and sands very smoothly.
Prepare the Paint
The paint in a can should be strained before being poured onto the rolling tray. In this way, you may avoid having to repaint an area because of paint that didn’t mix evenly. The use of a paint extender after straining aids in the removal of streaks. You may paint the wall’s edges where you cut in while the paint is still wet thanks to the extended drying period. You may potentially cut down on the number of coats of finish paint you’ll need if you prime the wall with a color that matches the finish.
Climb Up the Wall
The greatest results may be achieved when rolling a wall immediately after cutting through. You can reach the top and bottom of the wall with ease by attaching a two-foot handle to your roller. If you begin at the base of the wall and roll in a straight path to the top, you will complete the task fast. If you roll back down over the same place, the streaks will disappear. Paint drips onto horizontal surfaces, so the ideal moment to reload is when you reach the bottom. Paint a second line that overlaps the first by approximately two inches and tape all the baseboards.
