What does the + stand for in ASTRA-GLAZE-SW® +?
ASTRA-GLAZE-SW glazed masonry units have always been a low maintenance product, but in the past, certain types of graffiti were more difficult to remove. Trenwyth formulated a process that makes ASTRA-GLAZE-SW masonry units even more graffiti-proof, and have reintroduced them as ASTRA-GLAZE-SW® + units. New built-in protectants in the PLUS units act as an invisible shield which withstands spray paint, permanent markers, grease, and crayon.
