Using sand to texture decks

[TSP]

Pumice is a natural mineral - volcanic ash formed by the solidification of lava that is permeated with gas bubbles. Pumice powder is used chiefly as an abrasive and is among the softest of all media. Use pumice powder for less aggressive operations where the protection of the surface is of supreme importance. Pumice is the best media choice for tumbling plastics.

Thanks guys... Pumice is the way to go. I checked in a Glidden paint store and the only product they have is sand. I'll be checking tomorrow other paint stores.

I was thinking in relation to the application, how about masking all the areas and using a roller to apply the paint mixed w/the pumice. Later remove the masking and paint everything over w/ the spray gun. What do u think??
