Las Vegas Handyman repairs drywall every day. Lots of homeowners repair drywall as well, but may lack a little when it comes to matching the texture. Matching texture is not easy, but it is cheap and you can practice before you apply it to the wall.
Before you spray texture on a drywall repair, make sure the patch is good. It should be flat with no bumps. You can hold a shop light next to the patch and shine light along the wall. If the patch is not flat you will see shadows behind the uneven areas.
Once the patch is flat, use try to remove the borders of the patch. Grab a toothbrush and some warm water and use a swirling motion to minimize the border of the patch. You want to remove the drywall mud that has filled the surrounding texture.
For small patches, the aerosol cans of texture work great. Practice on a piece of cardboard or scrap material and get the spray pattern right. You can change the pressure in the can by holding it in cold or warm water. You can use the dial setting to control the size of the splatter. Practice until you have the right look. I generally start with a large sized splatter and then move to small splatter. It takes some playing with to get it looking right. Let it dry and then take one swipe with fine sandpaper in a sanding block to level the top of the texture.
