I am done tiling the house and now its time for grouting, i did a lot of individual small room but never a big room like that, 800 square feet i believe

how do i proceed ? im using Mapei ultracolor grout. how many batch should i do ? do i only grout let say 10 feet by 10 feet every time and mix new grout ?

Thx

read the instructions very carefully and when mixing new batches measure the water out exactly batch per batch ultracolour is rapid setting so dont get caught out by this by doing too large an area at a time

i grouted some rooms downstair and i found that the grout thickens verry fast when spreading it, what would you suggest to be a good amount to mix every time ? 1/4 of a bag ? Tiles are 13x13 3mm lines

I find you only gain enough experiance in grout amounts through, erm, experiance

How bigs your bags ?

they are 5kg bags

after initially mixing, have you left it to "slake" and then re-stirred before starting to grout?

definetly let sit for 3 mins or so then remix ! ultacolor is extremely quick setting,with a big floor like that its hard to beat two people grouting,one grout and one wash,works well for me.

i think ill try the 2 person method mixing half bags

once you have grouted ,wait for a couple of minutes then in a circular motion and with a wet(not soaking) sponge,go over the tiles you have grouted.Wait a further 10 mins before using a clean sponge and a clean bucket of water to wipe away the excess grout residue.

TIP; just wipe once the one way with the sponge then turn it over and wipe once again ,then rinse the sponge and repeat the process until all grout is removed from the face of the tiles.

sounds like u might be overworking it when u r grouting. try putting a liitle less on the floor
tel.

Lets hope you have a washboy ??

i did the kitchen today, looks good only some places the grout was comming out of the line when washing it had to fix it... what is the cause of it ? maybe i didnt push it in enough with the float to begin with ?

waited 20 minutes before washing it, ill post pictures tomorow when its gonna be dry

Either joints not filled properly or grout was too wet....

spot on Dave,probably too wet a grout mix.

yes bri....too wet a grout mix can retain air...these air bubbles pop as you wash off and leave holes....thats why you also never mix grout at too high a speed if using a paddle mixer..and can happen when your mix is to sloppy..

thx for the advises this one is good enough for me but ill try to make it beter in the rest of the house

Thanks for the picture, we like pictures Any chance of posting one a bit bigger ?

its a cell phone picture, ill get better ones after im finish with the other grout in 2 days
