Randy,

For future reference, this was recently posted over at inspectionnews.com

"From the Design Manual produced by Marble Institute of America.

Residential Stone Counter Top Installation

- 2.17 Spans & Overhangs

- 2.18 Stone counter tops under 1-1/8" thick should not span more than 2'-0" between support centers. Spans should always be minimized. 3/4" counter tops should be installed on underlayment.

- 2.19 Unsupported overhangs shall not exceed 6" on 3/4" counter tops or 10" for 1-1/4" counter tops. In an overhang condition, the supported area must be firmly secured and properly anchored to insure the unsupported area, when loaded, will not cause failure of the setting material. Mechanical anchors and gluing are recommend for overhang supports. If overhang exceeds the maximum amounts, proper brackets, legs or other rigid support must be added by the cabinet maker of builder"

Hmmm,

Not to get things off-track here, but I don't think a countertop can issue an insurance policy for anything. I'm sure the author meant to say ensure. I'll bet more than a few of us make this same mistake.

OT - OF!!!

grain colors? and other non-essentials.

Max Factor has all you need to know about cosmetics. We don't inspect for that unless it somehow becomes a "very sensitive issue." Let the women cluck over the minor trivialities in their nests. It may be more important to them.
