| Mar 14, 2015 at 15:06 | comment | added | C.Thomas | Based on your advice, and my own research, I guess the best solution is to pack the entire gap with a wide joint mixture of sanded cement type grout ( with polymer additives) and after drying seal it with a penetrating sealer. Does this sound right? | |
| Mar 13, 2015 at 22:43 | comment | added | Mazura | @C.Thomas 1) correct. When, in time, the grout cracks away from the wall, if it's a big enough crack you can just add more grout. If it's to small, you have to remove enough grout to make the gap about an eighth inch or it won't hold, or give up and use silicone. | |

| Mar 13, 2015 at 17:55 | comment | added | Mazura | @C.Thomas Epoxy is definitely another option (consider replacing 'caulk' in your title with 'solution'). It becomes obvious once grout has cracked, with caulk it's hard to tell it's failed until you see mold. Akin to the 24 hour band-aid rule, you don't want something absolutely impermeable always trapping water. IME, A bead of caulk that has come lose, soon turns into a mold party because it never gets a chance to dry out underneath there. It's not that grout is all that porous (once sealed), it's that caulk isn't at all and it creates a 'situation'. | |
| Mar 13, 2015 at 14:18 | comment | added | C.Thomas | I don't know if it's a kit or homemade. I had to chisel out what looks like semi-brittle epoxy about 1/4" thick and underneath was two strips of plastic backer rod this which was moist to the touch. I noticed no mold! If I fill it entirely with grout,that's breathable won't water and moister seep down though the grouted gap? | |
| Mar 13, 2015 at 14:03 | comment | added | C.Thomas | I don't know if its a kit, looks homemade but I dug out two layers of plastic backer rod which was covered with what appears to be semi- brittle epoxy about 1/4" thick(I had to chisel out) and the backer was moist. | |
