Richard Posted January 22 Report Share Posted January 22 Any suggestions on how we can prepare the surface before we apply DiamondFinish Clear to outside exhibits that have deteriorated from UV exposure? In order to remove the damaged clear coat, we will likely employ dry ice blasting, but given how uneven the surface is, I'm not sure how feasible it will be to give all areas a light sanding before applying DiamondFinish. I'm concerned about how well DiamondFinish will bond to the old remaining finish. These structures are made out of foam, coated with a tough polyurethane, then painted with a variety of colors. Our goal is to preserve the paint after the dry ice blasting and applying your product to permanently protect the surface. Quote Link to comment Share on other sites More sharing options...
