Attaching Marble To Window Sills

[luvrbus]

What is a good product for attaching marble to a window sill the thin/set is not working it comes loose and I need a product that will not bleed through the marble got answers anyone ?

[bevans6]

I would try construction adhesive, probably a fast grab type.  You would have to test for bleed through, but the manufacturers recommend it for marble.

Ditto on the recommendation Clifford clamp if possible.

When I had granite installed in my bus they used car bondo.I know it sounds strange but it has not moved in 11 years.The only thing I do not know if it will bleed through.If that will not work I would use pure silicone.

IF:it is porous on back GE silicon works great!  will have to chisel off.  Notice:  IF      That's what counter top people here use and I used in my coaches.  If it is to smooth on back might ruff it up to help what ever you use stick.  FWIW   Bob

Agree with Bob GE silicon. or backer board construcion adhesived down and then Marble Thin set. regular will not work.

I will "3rd" the clear 100% silicone....

There is not much that it won't hold!
