Shower unit which was installed 4 years ago started to leak water between the bottom rail and the shower base. As we were going on holiday, I removed all of the grouting and allowed the whole thing to dry out during the three weeks we were on holiday. Re-sealed using clear mastic and left for 24 hours before using the shower again. Some of the sealant has now turned white and gone very soft. Clearly I've done something wrong but I'm not sure what. Any ideas?
