How to apply a Splatter Knockdown


Splatter knockdowns are the most popular concrete pool deck resurfacing finish. Their surface is non-slip which is ideal for wet areas around pools. They also diffuse the temperature which makes them slightly cooler to walk on with bare feet. Let’s go step by step to show how you achieve a splatter knockdown finish.

After your normal surface preparation has been completed and all areas to be protected have been masked off; it is time to apply your skim or base coat. This is done with a magic trowel or rubber squeegee.

If you are going to have a grout line then your base coat would have the desired grout color mixed into it. Make sure this coat is as smooth as possible and then let it dry.

Before moving to the next step let me say, I have seen these applications done many ways but I believe the best and most consistent look is achieved by doing two spray coats. That is the technique I will explain here.

Once we have our first spray coat mixed up with the desired color it is time to get busy with the hopper gun. I have found a Marshalltown Sharp Shooter to be the absolute best gun for applying spray textures.

A tip here is to learn to do a splatter knockdown by sight and sound. Look to see what the texture is looking like and listen to what the hopper gun is sounding like. The only thing I concern myself with is that my compressor is set at 55 psi before I start. After that, everything is controlled by pressure and volume at the gun.

I like to spray my first coat with very low volume and almost full pressure. This makes a hissing sound and the texture is very grainy. It is not big and bubbly but more like a 60 grit piece of sand paper.
