Tile repair mortar - what am I doing wrong?
While removing a shower/tub door recently, I managed to pull four shower tiles off the wall. The home depot guy sold me a small tub of "tire repair mortar". Following the instructions didn't work...
The tub says to use four ounces of water per 1.5 pounds (i.e. the whole tub) of dry mortar. I only need a small amount, so I measured about 1/4 of the tub and put in one ounce of water. The result was too dry to even clump together entirely. When i added a second ounce of water, it became moist enough to form and spread (about like play-doh), but it certainly didn't stick to anything. I could press it onto the back of the tile and it would barely stick ... and certainly wouldn't stick the tile to the wall. It wasn't until I added a third ounce of water that it started to seem paste-like enough to spread around and adhere to things. But at that point I'm using three times as much water as the instructions say.
I ended up not attaching the tile and just cleaning up to try again another day. Any thoughts or advice?
