Washboy sponge leaving a bubbled film when cleaning off. Why?

[Jeff the tiler]

Hey all, No I have not filled it with fairy liquid etc! It is just seems when sponging off it is leaving a slightly bubbled appearance.

I hope that make sense. Tried a new sponge and again the same. Had original sponge for circa 5 months now so should be broken in. It seems to more evident on polished porcelain.

Any ideas?

Sorry should of added, using a sliced sponge.

rinse the sponge as dry as possible pass over the tiles a little slower maybe

Try saturating the sponge for a few hours before grouting

Out of interest, what grout are you using?

Bri Have had this with Weber, Tilemaster and Bal.

I had something very similar happen with Weber grout on a polished porcelain, it's the only time it's happened. The tiles still polished up ok.

I try and use the minimum of water....

It's only happened with me on polished porcelain.
I wouldn't worry about it as it does polish up perfect.

Bugs you though!!

Yes, now you mention webber, it does seem to bubble up something awful!!!

I get that a lot these days I just buff the tiles while the dust is still soft

Out of interest was it on walls or floor?

 

[Jeff the tiler]

It was on the floor

Jeff...it happens and is not a worry.. but DO NOT leave it to dry in the joints.. this will lead to polymer leaching.
