Problem with colour discoloration in tile grout for porcelain tiles

[Peter Hougham]

I am getting white marks and pale patches in a beige grout. I am being recommended to use porcelanose colour stuk rapid tile grout. I am unable to find mixing specification that I am certain of. One internet site recommended using latex instaed of water . Any useful comments? Thanks

Sounds like it might be efflorescence? Can you take any pictures?

How long has it been grouted ?

 

[Peter Hougham]

Grouted 3 days ago. I do not think it is efflorescent- could be polymer leach

 

[Gazzer]

Could be a mixing problem.

 

[Peter Hougham]

Do not think it si afflorescence - probably polymer leach

Granofix

It does sound like polymer leaching from over wetting when washing off..

Was the grout left to set up before washing off ad what washing of method was used.

 

[Peter Hougham]

Yes the grout was left before washing off as the tiler said it would gave pulled out the grout. The white was there before any washing off and subsequent washing has not reduced it.
