Tom,

I am a commercial interior designer. I think we need a reference book. Is there a book or publication that succinctly provides information on the advantages and disadvantages of each type of stone – plus it’s correct installation method (grout line size, type of grout, sealing, maintenance etc.

Regarding Travertine – what are the disadvantages to using travertine (on the floor in a residence hall lounge – to be precise…) Thank you for your help.

Hi Linda,

The Marble Institute of America has all the information guidelines that you needed. Check their bookstore and
consumer resources pages.

Regarding travertine on floors, it is widely used but there are some important considerations. For example, if the travertine is not properly filled, then high heel shoes can literally pop the fill right through the travertine, thus leaving pits randomly throughout the floor. To avoid this, you should specify “travertine which has minimal fill and all holes are adequate filled to avoid damage from foot traffic”.

Joints are important. The tightest reasonable joint should be 1/8″. However, if your tiles are quite large, then 3/16″ is reasonable as well. Grout at this width should be non-sanded and filled flush to surface. Grout and thinset should have a dry-polymer additive to increase strength. There are brands like Merkrete or Laticrete that are well known of strength and quality.

Best wishes!

I have an all glass Sunroom. My problem is: a few of the ceiling seams leak when it rains. Is there a sealent I can apply myself to the seams to stop this?

Thanks,

Hello Geri,

You need a commercial grade silicone or polyurethane sealant. I recommend Dow Corning 790 Silicone or Tremco Polyurethane (dymonic). Use whichever you can find first.

Best wishes,
