How to repair hairline cracked on the shower floor without damaging waterproofing??

saroj9

I've discovered a hairline crack in one of the tiles in my shower, and I'm concerned that replacing it might compromise the waterproofing. Since I live in an apartment, damaging the waterproofing during tile replacement would be a major issue. Could you please advise on how to fix this without risking damage to the waterproofing?

Hello @saroj9 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your tiled floor.

In this particular situation, I can only suggest putting Selleys 300g Wet Area Waterproof Silicone Sealant - Dark Grey and spreading it with Pro Renovator 38mm Plastic Scraper - 38mm. Your goal is to push the silicone into the crack as much as possible and leave a miniscule amount on the surface covering the crack.

Please note that this is a temporary repair and at some point, the tile will need to be properly replaced. I'm sorry, but I'm currently unaware of a long-term repair method for damaged tiles. I also recommend getting some quotes from tilers who are familiar with tile bathroom repairs. This will give you the opportunity to prepare for the cost of the repair.

If you have any other questions we can help with, please let us know.
