Applying a knock down texture to your wall has many advantages. One is that it can easily disguise imperfections on your wall and at the same time give it a distinct design. It can also accentuate the current interior design of your room, having a complementary effect on the current setup.

Step 1 - Prep the Surface

This could be the longest step in the process because depending on the condition of your wall, damaged areas and imperfections need to be repaired first. You can also prime the wall, but if it has already been painted and is in good condition, just sand the wall and scuff it up a bit.

Step 2 - Mixing the Powder Compound

Mix the powdered texture compound in the bucket and add some water. Read the instruction on the powder’s bag to know the exact mixing procedure, as the ratio may differ for each company.

Step 3 - Application

Attach the hopper gun to the compressor and fill the gun with the mixture and spray the wall evenly. When spraying, never stay stationary at one portion to avoid blotches on the wall. Keep the gun moving at all times to ensure an even distribution.

Step 4 - Knocking Down

Get the brush and dip it into the texture compound and dab it on the wall with fast and short stabs. Do this to the whole wall. Let the wall dry for 30 minutes and scrape the uneven portion with the knock down knife. Once you’ve done the whole wall, prime it and paint it to finish your knock down texture.
