Patching a wall is an easy way to fix holes or dents that your wall gets from everyday wear-and-tear. The challenge with wall patching is putting that fresh coat of paint over the patch, and making it blend in with the paint job of the rest of your wall. If you have a wall patch you are trying to paint to be cohesive with the rest of your wall, learning some tips for success can help you get your wall looking as good as new.
Select the same paint colour as the rest of your wall. If the original paint colour is available, use that. However, if it is not, you will need pick up swatches similar in colour and finish, then tape them up on the wall and look at them in various lights. Select the one that matches your wall.
Wipe down the patched area using a damp cloth, to remove any spackle dust or dirt before painting. Wipe again with a dry cloth to ensure all moisture is gone and the wall is completely dry for painting.
Paint over the patch, starting in the centre and working your way out to the edges. Allow this paint to dry for a couple of hours. If the patch is no longer noticeable, then leave as is. If there is still a noticeable difference, continue.
Apply a small amount of paint to your brush and dab it over the edges of your paint patch. You want a little bit of texture in your layer of paint, to work with as you try to blend.
Take a new, unused brush and---in brisk strokes---begin brushing your textured layer outward at the edges, all the way around the patch. Allow the area to dry for two hours, and repeat as necessary, until the patch is blended.
If the original paint has a gloss finish, you should consider painting over the entire wall, as matching new gloss paint to old gloss paint, that has lost some sheen, can be a challenge. You also can try to find the colour of paint in both gloss and flat finishes and either mix the two, or apply gloss paint first, then dab on the flat finish, lightly, using a sponge.
