" I would like to have a walkway made with tumbled stones -- but is there a top coat of some type to pour over top of the stones to create a hardened surface?  MaryAnn Kocsak, Hamilton, NJ  Dear MaryAnn, I&amp;#039;m presuming that by tumbled stones you mean the 1&amp;quot;-2&amp;quot; large, river-washed stone often available in many garden centers. To form a walkway with these highly decorative stones, first a concrete walkway is laid in the normal way; then, before the concrete has set, the stones are pressed into the surface by hand. Although the results can be spectacular, it is a very time-consuming process, and one that&amp;#039;s often best left to professionals: The cement mix has to be just right, or else the walkway will begin to fragment after the first winter. Alternatively, smaller stones can be included directly in the concrete mix; the surface is then brushed before it is completely dry to reveal the stones. Again, this is a process best left to professional installers. "^^<http://www.w3.org/2001/XMLSchema#string>
