Efflorescence

Quite a few comps will sell products to help.. some grout haze removers work and others will not.. but over wetting and washing off to early is the cause 90% of the time.

Believe it or not Dave this grout was left at least 30 mins before cleaning and I can't see how I could of used any less water. Used it lots n never had issues so it must be something I've done different.

Was it firm to touch..? some slow setting groits take quite a while to set up and this can be increased with vitrified biscuits as they don't soak any moisture up..

I like to use ultra colour as it sets quick, just as i like it..

All i can say mate is use a white scotch pad and some élbow grease.. what tile type is it, natural or a looky like..?.. the other way is to re-colour the grout.

It's looky likey cheap porcelain, I'll give it some elbow grease tomorrow see what happens. Cheers Dave.

By leaving the grout to set longer, firm to touch and then you will not soften the grout to causing polymer leaching..

Always leave it on until it's at it's hardest workable level. Will just give it a by ball in future.

Ive got a similar problem to as described above, with grey grout too. I thought I was quite careful with not leaving too much water on the sponge but maybe I didnt leave the grout long enough to dry. I have sponged with excess water and will leave to dry to see if this improves it. I see people also say cleaning the joints with a scotch pad and solution, would

Cement,Mortar and Efflorescence Remover (HG Limex)

Be a good product to use, and silly question but where do I get the scotch pads people refer to? Is it a case of applying the above solution to the pad and scrubbing into the grout? Thanks

Can anyone recommend a good product to fix this, I tried

Cement,Mortar and Efflorescence Remover (HG Limex)

With white scotch pad but it didnt make any real difference?

Thanks

I would use Mapei Keranet to clean it and next time use Mapei grout for a hassle free grouting.
