I have been using plaster-grade sand, poured on freshly rolled LPU paint
, then swept of excess and top coated with additional LPU, for thirty years or more. The last time I stripped the nonskid for repainting, I was amazed at the weight of the paint
and sand detritus I removed. I am getting ready to renonskid the cabintop and am interested in something lighter, yet possessing the same grit texture as sand. Sterling Paint (the LPU I have always used) has what appears to be hollow spheres of something that approximate the grit size, the weight is light as a feather, and the material seems to float atop the LPU base coat. But it is quite expensive, and I'm not sure of the durability of the product over time.
I have used other materials in the past. An acrylic
industrial nonskid, used on aircraft carriers, gave good texture, but soiled and stained badly, especially if oily products came in contact with it (damned mayonnaisse!). Crushed walnut shells, cork bits, neoprene bits, and other stuff all got tested. Nothing held up like ordinary sand, or stood repainting without significant loss of traction.
I'm hoping the collective experience of the forum can help me find a lighter weight, equally durable, and (hopefully) thrifty substitute for common washed plaster sand.
