Mini Texture Gun
We've had some good results using texture from aerosol spray cans—and some disasters. The texture blasts out fast and heavy. One wrong move and you've got an over-textured mess.
This little hand-pump gun is much easier to control. It spits out just a little texture with each blast. So you can spray on a light texture, then add more until it looks right. Still, it's best to practice on some cardboard first. Also have a bucket and sponge handy in case you need to wipe away a misfire and start over. We got good results matching orange peel, splatter and knockdown textures, but lousy results with popcorn ceiling texture. The gun is available at some home centers for less than $20. Or search online for "Homax 4105." The kit comes with texture packets, but watered-down joint compound works fine too.
