Mosaic outdoor bench
I made a mosaic outdoor bench project last year, by laying tiles and mosaic elements on marine plywood that had been treated and weatherproofed. I used a thinset cement to secure the materials to the wood, the smoother elements and shells in the design pop off from time to time. Is there something I can overlay on top of it, to protect it and keep this from happening? I really want to put it back outside this summer.
