Advice needed grout cracked - TilersForums.com

[Ian Barrow]

Good evening, looking for a bit of advice. Had a new bathroom fitted a couple of months ago and grout in all corners has hairline cracks. Builder has regrouted once and covered with clear silicone. However, has cracked again under sealant. Is Mapei grout and matching sealant colour isn't great. Is clearing of cracked grout and application of sealant in corners best resolution?

The corners should never have been grouted in the first place, colour match silicone should of been used...

Thanks Andy, if we replace grout with sealant, does the grout have to be fully removed? Are there any risks of leaving cracked grout with clear silicone over the top as it currently is?

Ya typical builder then....

Problem = Builder.
Solution = Tiler.

Rake out and clean the internal corners and then silicone.
Grout acts as a water magnet, sucking water into corners and preventing silicone doing it's job.

So hes grouted, grouted again and then clear siliconed it? Wrong, wrong and wrong again!

Is this the same Ian Barrow that used to live near Guildford?

Soŕry WalLuigi, no.

Any of you guys used the Mapei colour match sealant in the corners and can you get a good finish/match with grout?
