Last Patch Dymond

Bonstone Last Patch Dymond

Last Patch™ Dymond is an exterior grade, UV stable stone repair compound for granite, marble, travertine and any other highly polished natural stone surface. It offers a very fast (and adjustable) cure speed, excellent clarity, non-shrinkage, and extremely rapid hardness development, which make it ideal for harder, glossier stones such as granite.  Plus, Last Patch™ Dymond provides exceptional resistance to sunlight, which sets it apart from all other products on the market.
