I have a "porch" or deck with attached ramp. When we built them, of course, we used pressure treated wood. Problem arises when children can't resist running up and down the wheelchair ramp even when the weather has been rainy. The natural problem occurs: pt wood is slippery when wet. Ideas for possible solution to slippery problem, please. I heard somewhere that adding, oh, 1/4 cup of sandbox quality sand to paint will provide sufficient grit for gripping. Bright ideas? Help. Posting No-trespassing signs doesn't discourage wee-little trespassers with skateboards all the time.
When I painted my workshop floor, I remember that the store sold an additive that would make the floor non-slip. Sand could work, but I'm sure this stuff is formulated to disperse, and you could have them mix it in for you. Any paint store or hardware store should carry it.
Another possible solution is buying long narrow bathtub strips (not the silly flowers!) to lay along the incline, say every four to six inches. I did this on a painted piece of ply sloped off our outdoor garden shed, due to icy winters here, and it has worked fine. -Barb S.
I know that the pain with sand thrown on it works. My father decided that the painted foredeck of our ski boat needed to be non-slip so he used the paint and sand. I don't know how much knee skin I left on that deck over the years. :-)
#1- Use roll roofing material. Nail at just the top. Depending on how much use it gets might have to be replaced every year but not too expensive About the same as 1 gallon of a good quality deck paint. A roll is 100 feet long so you might be able to use the same roll for a long time depending on how long the ramp is.
#2- Go to a boating supply store or some lumber yards and get some rubberized coatings used for on docks. They have some choices on the texture.
#3- Again the boating supply store and get the self adhesive no-slip strips about 3" wide. I have not had too much luck with these as they keep coming loose after a short time.
#4- Depending on how much space is between the boards you might try non-slip stair nosings.
