The concrete walkway and porch in front of my home are quite slick when wet due to the finish. I have considered sandblasting the walk, but I’m not sure that would really do the job. And I really don’t want to apply the “peel & stick” non-skid tape. What would you recommend?
Try mixing a 25% solution of muriatic acid and water. That’s one part acid to three parts water. Add the acid to the water. Remember, muriatic acid can be harmful to your health. Be sure to wear rubber boots, safety goggles, rubber gloves and protective clothing. Pour the solution onto the concrete and let is stand for approximately 10-to-15 minutes before flushing the entire area with water.
Allow the concrete to dry to determine if the new finish meets your expectations. More than one application may be required to achieve a coarser surface.
