Texturing walls doesn't have to be done by a professional anymore. Materials are available at local home improvement stores, and easy techniques that you can follow are so simple that just about anyone can do them. Once the job is complete, you can step back and look at the textured surface you created, knowing it is just about as good as professionally finished rooms and for a lot less cost.
Textured paints are available that have material mixed in with the paint. All you have to do is brush or roll the paint on, and let it dry. Depending on the amount of material in the paint, the process might leave a slight rough surface or look fairly bumpy. The paint isn't inexpensive, but when compared to the cost of hiring someone to texture your wall, it is a cheaper alternative.
If you have a few different sized flat-edged trowels and some drywall compound, you can texture the walls with little expense. Dip the trowel in the compound and spread it onto the wall, scraping it out thinner as you drag the trowel over the wall. Continue making these textured strokes on the wall in various directions to complete the wall. The compound isn't costly and is readily available at home improvement stores since it is used to cover drywall seams.
Drywall Texturing Powder
Drywall texturing compound is similar to regular compound, but it is meant for texturing walls. It comes in a powder and is mixed to fill into a paint sprayer. Depending on the nozzle adjustment, you can spray on a fine speckled texture or a more splotchy one. Spraying the texture on is a little easier than applying it by hand, but it also leaves a different look. You may want to flatten down the speckles with a trowel for a slightly smoother surface.
A simple look that gives walls the appearance of brushed plaster is accomplished by using a long bristle brush. Roll on a thin layer of texture compound that is mixed about the consistency of a white glue so it won't run. Roll on in small areas at a time, then place the brush onto the surface. Rotate the brush around in a circle, keeping the bristles on the wall, which creates a circle of bristle-made lines. Repeat with other circles, either touching each other at the edges or overlapping .
