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...
KBS Coatings Posted January 23 Report Share Posted January 23 Do the dry ice blasting and then clean the surface thoroughly with KBS Klean. Take your time on the cleaning to make sure it is done well. Let the surface get bone dry. Then you will apply DiamondFinish Clear. You do not have to scuff the old coating if it has been cleaned extremely well. Please let us know if that helps and if you have any additional questions.
