The unfortunate part was that we had to remove all of the grout before we could replace it. This was quite a job. We used manual tile saws, small nails, and razor blades to pick the grout out in between the tiles. Our grout joints were small, so we could not use power tools. We had to be very careful not to damage the tile, as we picked out the grout.
|Removing the grout in between the glass tiles was a slow and very tedious job.|
It took two entire weekends to completely remove the old grout. It was such an unpleasant and tedious job that we wanted to make sure that we don't have to do this ever again. So we researched online to find out why this may have happened. Apparently, its not that uncommon. The most common reason for this type of grout failure is that the grout was too old. We learned that grout expires in about one year after it is manufactured, and it turned out our grout was about one year old. We also wondered if the additive could have caused the grout to fail.
We then did lots of research to find the best type of grout and to reduce our chances of grout failure. We simply did not have the energy or will to remove the grout again. We learned of epoxy grout which was more expensive than unsanded grout, but never needed sealing and did not stain. We decided to use epoxy grout this time. Epoxy grout is sanded grout, but the particles are much smaller, so it can be used with smaller grout lines.
The epoxy grout worked really well. It was runnier and a little harder to work with due to its runny consistency. However, once we got used to it, it was easy enough to use. It required special scrubbing pads and sponges to scrub the grout off the tiles once the grout had a chance to dry. This was a little more difficult than using unsanded grout, but it was not too bad.
The epoxy grout dried much faster than the unsanded grout. By the next day, it dried and felt very hard and solid. It was not possible to scratch it, and it was not chalky at all. Finally, success with the grout. What a relief!
