 Re: Grout problems x4 regrouts | |
They need to make sure that all of the old grout is fully out of the grout joint. If they dig deep enough with a rake they should hit adhesive and that's what the new grout will stick to along with the edge of the floor tile.
Accidents can happen in any job, but it's still their problem to fix it for you.
If they dig more and use a decent flexible wide-joint grout or use grout additive in a standard grout you should find it will bond to the wall grout better. |
