expanding foam and yellow grout - TilersForums.com

[shogun rua]

Hi Guys,

I had a customer phone me for advice she told me she had her bathroom done and after 2 weeks the grout started to go yellow :yikes:
The people who did it said it was because she smoked in the kitchen :lol: which has 3 doors between the bathroom, any ideas why grout would turn yellow after 2 weeks?
Also can you use expanding foam between window frames and walls, what i mean is will it contract and expand with the temperture after its set?

Cheers

Paul

Yep, bleach can burn white grout, nice and bright white and then goes yellow.
