Im looking at a product from Daich Coatings ( www.daichcoating.com ) called Roller Rock that is advertised to give a textured slip-resistant finish that I am interested in applying to my front porch steps. I found after my first winter in Canandaigua that those steps become very slippery with snow, even though I shovel and sweep quickly after each storm. The current painted surface is very smooth. Any information on this product or similar surface treatments would be appreciated. I've only got four steps to do.
