can drywall stay wet for a long time?
Comments (2)Before the bathroom remodel, I would have water leaking into the kitchen if there were several people showering in a row. When the wall was torn out, it became clear that there had been a lot of wetness for a long time....no real leak, but the joists and all the wall board and the insulation were wet and mouldy. The only explination my contractor could give was that somehow the water was going through the grout. Apparantly it was never properly sealed. Don't know if that's your problem...but it was mine.

Comments (5)First, your grout and mortar beneath the tile are not waterproof. Even a single grain of sand is porous. It will get wet and soak up water underneath your tile, so the mortar needs a mechanism to drain. I attached a photo so you can see near the drain pipe in the photo center lower edge and reference to "pea gravel to cover weep holes". Small weep holes exist to allow the MORTAR to drain as it will get wet - through the grout and even through the tile. Even the tile, whether ceramic or porcelain is NOT a waterproof surface (unless a glass-like glazed surface). You can see in this image, the shower pan liner is the waterproofing membrane going up the wall on the left and over the curb on the right. It also seals to the drain base. But above that base is the female threaded collar which accepts the upper section of drain. That female threaded collar has weep holes which should be covered with pea gravel so that mortar does not get into them while spreading mortar for the tiles. Different drain systems and styles have different mechanisms that allow the mortar beneath the tile to drain. Most of the shower water washes over the tile and grout and goes down the drain you see in the shower. But water also soaks through the grout and the mortar down to the waterproof membrane beneath that routes it to the drain assembly where the weep holes allow drainage. While excess water drains through weep holes, most will evaporate upward - the same way it entered the grout and mortar. The fact that you have a linear drain does not change this fact of shower drainage. Under your tiles exists a bed of mortar on top of some method of waterproofing. This bed of mortar MUST drain or it WILL fail. First the grout will discolor. Then the tiles will discolor. Then it will all come loose. Generally, people take their showers during one particular time of day, then the shower is unused until the following day. The mortar and grout will dry out during the downtime - certainly within a 24 hour period. Perhaps what you see is simply a grout discoloration from first-time-wet and it has changed color from its original. I would not be worried about the couple of softball sized wet areas. In a custom shower, especially if a mud pan was made, it is not unusual to have a low area here and there. It is hard to be 100% perfect with setting tile. But if the grout IS actually wet - there may be a problem. It should dry in a 24 hour period. From what I can see of the floor tile and wall tile - it looks like a fantastic job! No rookie did this.

Comments (10)It was done in August...lol. We're still trying to work out all the problems. They tiled on top of bowed studs. They mixed unsanded and sanded caulk in joints. The caulked in the wrong color. They grouted in the wrong color. They grouted in change of plane joints. Grout chunks and caulk were smeared all over tile surfaces. Bright white adhesive came up through the penny mosaic tile shower floor grout. This was new construction - so 4 full bathrooms with at least one of these problems. Most recently they recaulked with SPECTRUM brand caulk that was supposed to match ColorFast CUSTOM brand caulk. NOT EVEN CLOSE!...See MoreWet spots in new shower & more issues
Comments (23)Appreciate all the responses (sorry for being slow to respond, but been pretty down about this and tried not thinking about it over the weekend, which didn't work anyways). I'm emailing the contractor this morning, and will follow up with his response. In the meantime, we've also noticed that there are dark sort of beads allover the floor. I've circled one in red below. When you put your nail in it, it's rubbery sort of like silicone. I wonder if these are tiny cracks and whatever is underneath is pushing through (though it seems odd that what's under the grout would be silicone or something soft?). More seem to be appearing every day. Thanks again....See MoreMongoCT
