Before you paint any room the most important step is to prepare all the walls and patch up all the holes that were made for pictures and other wall decorations. Use a strong light to go over all the walls because holes will cast a shadow and they will be easier to spot. Start by turning off all the lights in the room and closing the curtains. Then hold a trouble light next to the wall and move it across the surface. Once you found a hole or a trouble spot use masking tape to mark the spot.
Since the house constantly expanding over time the contraction can cause studs to pus nails out of the drywall, this is called a “nail pop”. You can just hammer the screw back in or take the srrew out the old screw and drive a drywall screw about 2 in. above or below the popped nail. Fill in any holes or nail pops with joint compound and a putty knife.
Tip: After applying joint compound, be sure to cover it with primer before painting to prevent “flashing.” Flashing occurs when joint compound absorbs the paint, dulling the finish.
If you have metal corner beads first shape the bead with a hammer to make it flush with the walls. Do not worry about cracks in the drywall since that will be covered by joint compound. .Use a level to make sure the bead doesn’t stick out past the finished walls or you won’t get a clean corner. Work on one side at a time—once the first side is dry you can square the other side. Once the first side is dry, apply joint compound to the second side. Then recoat the corner, let it dry and sand it smooth.
For filling small picture hanging holes use spackling compound. Apply the compound with a putty knife by spreading it really thin, do not worry if it does not fill in the hole right away since you will have to repeat the step at least 2 more times. Let each coat dry before you apply the next.
You’ll have to sand between coats if there’s any excess compound. After the final coat, use fine-grit paper.
For wall marks such as crayons and other wall stains use a special blocking primer that will cover so the stain does not bleed through the paint. Regular primer or pain will not work since crayons tend to bleed no matter how many coats of paint you apply. Apply primers such as KILZ and B-I-N with a roller so the texture will match the rest of the wall, we recommend buying a cheap disposable roller and then throwing it away when you’re done.
