adding abrasives to paint

On the job I am doing this weekend, the handicap stencils call for a 3x3 blue square with abrasives in the paint. I was planning to use silicone sand and a hand spreader. I've never had to add abrasives before and I'm not sure the best method is. I'd appreciate any suggestions.

The easiest way would be to spray your blue and while the paint was wet spread the sand by hand, you need to do this quickly before the paint skins over then paint your blue again.

Thats how I planned to do it Eric. I just wondered if there were any better methods out there. Thanks!

3x3? that seems kinda small for a hermie background. Where are you from? Also, I wouldn't bother with a second coat, just throw silica sand on top and move on to the next one....

Coat with paint, then broadcast a thin and even coat of aggregate, then add another light coat of paint to cover and/or semi-cover the non-slip material, more or less encapsulating the aggregate into place. This will give your customer more value because it will actually be still doing some good a couple of months down the road. Lastly, add a thinly broadcast top layer of sand...? on top of of the sill wet paint which will give it the standard & excellent non-slip capabilities for the next couple of months. Now, be prepared to charge more for giving the customer a better value than the guy down the road. Although, this method may not be needed if using slow dry paint, as the sand, beads, or 'whatever' will sink into the paint better.
