How to Make Non-Slip Paint

Annie Wang

Non-slip surfaces are an essential safety feature for patios, decks and outdoor walkways. While premade non-slip paint is available, the purchased version is thicker, grittier and less user-friendly than paint you mix yourself.

Adding non-slip paint to exterior deck flooring makes the area much safer.

You simply mix grit additive -- commonly found at home improvement stores -- into the paint color of your choice. Use a fine grit for areas where you walk barefoot, such as an outdoor patio or a bathroom, and coarse grits for places where you would be unlikely to walk barefoot, such as an outdoor concrete walkway.

Tip

You can also mix grit additives into floor epoxies and wood stains.

Warning

Do not use sand as a substitute for grit additive. Sand is heavy and tends to settle into the bottom of the paint; grit additives are made from lighter materials such as rubber pieces or walnut shells and tend to stay suspended longer in the paint.

  1. Pour the paint from your paint can into a large plastic bucket. This prevents overflow as you mix in the grit additive.

  2. Measure 1 pint of grit for every gallon of paint you use. You can increase the amount to 1 quart of grit per gallon, depending on how you want the surface to feel underfoot. More grit results in a rougher surface.

  3. Mix in the grit additive. Stir using a wooden dowel until the grit is thoroughly mixed.

  4. Paint the surface immediately, or pour the grit and paint mixture into airtight containers if you plan to paint later. Mix the grit and paint mixture occasionally as you paint to prevent the grit from settling into the bottom of the bucket.
