Let the texture dry for 24 hours before priming and painting. If you are aiming for perfect concentric circles, practice your artistic skills on a spare piece of drywall before attempting them on your wall. Apply the drywall compound to the wall using the roller, then use the teeth of the trowel to gently apply lines in the wet compound. This method requires drywall compound, a roller, and a drywall trowel that has evenly spaced teeth (or uneven teeth if you are going for a less organized pattern). This technique is often used to produce a repeated series of rainbow patterns on the drywall and is one of the more simplistic texturing techniques. The comb texture is produced using techniques that create lines of various widths and shapes in drywall compound. Take a look below at seven popular wall texture types and the techniques behind them. If you’re thinking that texturing is too difficult to do yourself, think again! While texturing should involve some degree of practice before deciding to texture a room in your house, the techniques used to make the following wall finishes are not as hard as you may think.
