Grout then caulk?

yazkJuly 5, 2013

Hi all

At the edge of my tiling (installed about 6 months ago) where it meets our bath/shower tub, the grout is now showing some minor cracks. Probably the result of the tub moving slightly.

I am going to re-grout over the cracks, but should I then go over with a clear silicon caulk? Or should I just now apply a white silicon caulk and forget any further grout?
My thinking is that caulk will flex slightly so not crack.

Thank You.

Caulk at any and all change of planes, never grout!

Remove the grout completely, fill the tub about 2/3, caulk with 100% silicone, let set for 24 hrs before draining.

Putting weight into it before caulking "pre-stresses" the joint so that, with water & bodies in use, the caulk doesn't pull away...
