I have a customer who wants us to grind his garage floor and place an epoxy coating on top of it.  He also wants us to fill in the seams of the garage floor to make it look like a single slab.  The garage was only installed January of 2009.  We explained that the seams are there to allow flexibility but he still insists on having it filled.  Should we use concrete to fill it or is there another product that will fill it nicely and smooth to make it look like a single slab?  One other person told me thin set.  Does that make sense?<br>
<br>Thanks all!<br>Georgia<br>
