Shower Floor Grout Looks Wet

The floor is tiled with large 60x60cm porcelain tiles laid on impey waterguard membrane and the shower tray is impey aquadec easyfit with the membrane laid over the top.

Shower floor grout looks wet.

The wet area is not caused by using shower as the shower screen protects this space. Hope you can help. If this isnt the case with yours you should allow grout to dry completely clean it with a small rotary wire brush a little dremel works great. So i decided to use another bathroom in the meantime.

As soon as we started using the shower the grout again started darkening like it was wet. Some grout has a sealer additive already in the mix. We had our guest bathroom shower remodeled one year ago 2 weeks ago my wife noted shower floor grout wet around the edges with some spots dry. The spots started spreading until the whole floor of the shower has dark colored grout although it is not even.

Had the guy who remodeled the shower come look at it. It is a new build first floor bathroom new extension on older house with a. He opened the wall to adjacent closet in the next room to assess the shower pipes and no leaks found. Click to read complete blog post.

The tiled floor has been laid for about 2 years and this problem has only just occurred in the last few weeks. The bathshower sits on normal wood floor boards while the tiled floor sits on protected plastic water proof base. Its a large bathroom approx 150 sq. 48 hours later the spots are still looking wet but are not wet to the touch.

Keep in mind the lighter the grout the more it darkens simply from the humidity of the shower. Epoxy grout is the best choice for showers because is water and stain resistant and requires no sealing. So we stopped using the shower let it dry out for a few days until the grout lightened up and then i resealed again.
