How to Mix Knockdown Texture
Knockdown Texture is a drywall finish that gives a mottled texture. While it is more defined or intense than the normal flat finish, it is much less pronounced than a popcorn finish, for instance. It can cost hundreds of dollars to hire a contractor or specialist to perform a knockdown texture job to blend in and conceal uneven walls in your home. Mixing your own knockdown texture makes a simple yet cost-saving alternative. Knockdown texture compounds can be found at most paint or hardware stores.
Step 1 - Prep Work
Cover your home flooring with a tarp or drop cloths to avoid potentially harming your floors. Attach your knockdown gun to the hopper. Use the dial to adjust to the correct setting based on the consistency of the texture, whether small or large.
Step 2 - Mix the Texture Compound
Make sure to wear gloves and safety glasses before you open the compound bag. Fill about 1/3 of your empty bucket with compound and slowly add water into the mix and stir until you have reached the right consistency. To avoid making the mix too soupy or too thick, add the water in, slowly stirring as your pour.
Step 3 - Apply the Texture Compound
The texture is achieved by spraying the compound onto the walls or ceilings to form the peaks which are then flattened out using a knockdown knife. You can start by assembling your air gun then proceed to fill the hopper with compound material. Spray against your wall or ceiling in a smooth, consistent manner to make sure the application is even. Your spraying speed will determine the thickness of the material applied to the surface, so maintaining your movements speed will ensure an even application. Wait for 5 to 10 minutes for the wall to dry—until it loses its shine— after you have applied the compound before proceeding to step 4.
Step 4 - Knocking Down the Peaks
Flattening out the peaks is the knockdown process which consists of using a drywall knife at the end of a pole and use it to flatten the peaks—not smoothing them—by gliding the edge of the knife down in a straight motion. The resulting texture adds a dimensional quality to the surface while hiding drywall imperfections.
When you take the time to apply your own knockdown texture, not only do you save time and money, but you also learn a little more about home improvement. A few minutes of your time can make a big difference in getting the projects you need to get done around the house.
