What's the difference in grout and concrete?
May 20, 2010
I’m doing a craft project of making some coasters with tiles in a mosaic pattern, and wanted to know what the difference in grout and concrete are. I was planning on doing the indirect method (pouring the concrete over the tiles in the mold) and was wanting to know if I should use the sanded grout or the concrete, then apply the grout?
Thanks for any answers.

Grout is basically the mix of concrete without the aggregates. Aggregates are small objects like pebbles or small rocks put into concrete mix to hold dried concrete together. If you remove the aggregates then you will get a weaker (more like grout) concrete. But Grout is basically a bonding substance without aggregates. If your making a mosaic then use Grout because concrete is not only very heavy, but Harmful if not handled correctly. Most concrete contains powdered lime which is very harmful if inhaled. Grout is meant for tile and would be the best option for any mosaic.
