Hand texturing drywall starts by rolling on a coat of thinned joint compound. A 5-gallon bucket of premixed compound costs around $13 as of September 2011, but construction material prices are notorious for fluctuation, often from month to month. When thinned to pancake batter consistency, a 5-gallon bucket of compound will cover approximately 200 square feet. A paint roller, large paint pan and an extension pole will add $15 to $25 to the cost.
Drywall contractors add a stippled texture to ceilings with a slap brush, or a crow’s foot brush, which runs about $9. You’ll also need an extension pole to hold the brush, which adds another $10 to $20 dollars, depending on the quality of the pole. If you have a push broom, the pole may fit the brush.
For creating troweled textures, sometimes called orange peel or knockdown, you’ll need a trowel. You can pull the trowel lightly over the rolled on texture while it’s still damp to smooth down just the tips or to add a swirled effect. Trowel prices range from $7 to $35 dollars, depending on the width of the trowel and the quality.
If you’re not into rolling on the thinned joint compound, you can spray it on. Drywall texture spray rigs are expensive, easily costing more than $300, but you can rent one for a fraction of the price at a local construction rental store. You’ll still need to buy and thin the joint compound, but you can adjust the nozzle of the sprayer to deliver thick or thin texture evenly.
