interruptions, obstructions, edges and corners without disrupting
pattern or joint alignments.

2\. [Accurately form intersections and returns]{.underline}. Perform
cutting and drilling of tile without marring visible surfaces. Carefully
grind cut edges of tile abutting trim, finish or built-in items for
straight aligned joints. Fit tile closely to electrical outlets, piping,
fixtures and other penetrations so that plates, collars, or covers
overlap tile.

3\. [Jointing Patterns]{.underline}: Unless otherwise shown, lay tile in

clean all ceramic tile surfaces so they are free of foreign matter.

> Unglazed tile may be cleaned with acid solutions only when permitted
> by tile and grout manufacturer's printed instructions, but not sooner
> than 14 days after installation. Protect metal surfaces, cast iron and
> vitreous plumbing fixtures from effects of acid cleaning. Flush
> surfaces with clean water before and after cleaning.
