soft shower floor grout

3 years ago

I just purchased a home and the grout on my shower floor is very soft. I can scratch it with my fingernail, it also comes off while cleaning. Is this an issue that i should be concerned about? In the pic below you can see the scratch i made with my finger nail.

Many of the resin based grouts are contraindicated to be used with pebble floors, as the spacing is too large for it to cure properly.

What does it look like when it is wet? Are you seeing the "grout" absorbing water and changing color?

Doesn’t look like it’s absorbing water. It looks a little darker while taking a shower but not much.

@Dewayne are resin based grouts softer than regular grout?

No, polyurethane, acrylic, or epoxy grouts are not softer than regular grout, when they set and cures properly. Until it sets, it can resemble playdough though. But it isn't designed to work with the big giant spaces between pebbles or penny tiles. It works great on any other type of installation. TEC's polyurethane based PowerGrout has been notorious for not setting up, and needing a hardener. But it too should never be used with pebbles.
