Cheers Dave. How thick should it be mixed and how long would you leave it before cleaning down?

 

[DHTiling]

Normally that grout is 1.1 to 1.3 ltrs of water per 5kg bag.. but i mix it thicker as as the polymers soften whilst leaving to slake it can go wetter... so stiffer than normal i say but wet enough to bond.

Is there definitely no join in the ply under that grout line?

 

[zzr-matt]

Defintely no join. Its about 500 mm to the nearest join one way and 700 the other.

loved that vid lol... mate it doesnt matter how long after grouting you sponge off.. Just dont put any pressure on the sponge at all when your doing it and you wont dig into the grout joint... But you do have to wait for the grout to start setting before you buff.

Sorry but that is so wrong advice.... Ultra colour is a fast setting grout , leave it too long and it cannot be tooled..

Sorry if its bad advice I thought you have to wait for grout to start setting before you buff off mate

looks like the grout joint is to wide to hold the thin grout bed you washed it down to thin leaving the tile edges prone to damage and probaly mixed the grout to dry need to rake out do again what sponge did you wash it off with a cheap sponge will pull out the grout .try washing off with an ardex sponge not wet just damp and do one sweep at a time cleaning spong after each sweep

 

[SJPurdy]

What type of ply was used?

 

[Sean SML Tiling]

Whats the ardex sponges like and how much? I use the nicobond sponge which is 4 quid each a little steep for a sponge but very good.
