1/8-inch and plug hole flush with material equal in chemical resistance, color, hardness, and texture to top surface. b. c.
After installation, carefully dress joints smooth, remove surface scratches, clean, and polish entire surface.
Provide scribe moldings for closures at junctures of top, curb, and splash with walls, as recommended by manufacturer for materials involved. Except where welding is utilized, use chemical resistant, permanently elastic sealing compound where recommended by manufacturer.
