casto

Well I have right now an 8ft verticle wall, and I am going to build it up soon. It's good to have parents in carpentry . I have the holds but have made some wooden ones that I want to have some texture, but spray paint and sand chips off, should I use a thicker paint. I like the idea of the epoxy and sand, I might try to see the texture, and difficutly in application, give me all your ideas...

As yo can see I'm new here , and I figured alot of you guys/gals know more that me. So I was curious what to use for texture on my home wall. I have a dozen or so extra wooden holds that Iwould like to give some texture, but spray paint and sand chips off. Is there a thicker paint or something so I dont have to buy some $40 texture paint?
