How do I make textured paint for my walls?

1. Fill a paint roller tray with flat latex paint.
2. Pour 4 to 6 ounces (113.3 to 170 g) of silica sand into the paint.
3. Stir the paint with a wooden paint stick.
4. Add more silica sand for a coarser texture.
5. Repeat the process of stirring before each application because the sand will settle on the bottom.

The above is a very basic 'recipe'. Most hardware and paint stores carry texture paint addititves and pre mixed sand paint

I 've thickened latex paint with spackle in the past to hide cracked plaster. Or you can put a layer of texture with the spackle with a roller after mixing the spackle with water before painting. It's a real pain to smooth it out if you change your mind. You can buy paint with an additive, also.

Hi Susan, you can add texture by using a product called joint compound. You can add it to your paint or actually texture your walls first. Here's a video that may inspire and inform you more.
