How do you get clean grout lines? - TilersForums.com

[Lisamoore]

Hi Guys,
I haven't been tiling long and have been told/seen 3 different ways to obtain clean grout lines.
Not sure if all/any are OK or it's personal preference but thought I would ask...

1. After applying grout, wait 15 mins ish and then run your wet finger down the lines, wait 40ish mins and clean off tile.
2. After applying grout, wait 15 mins then use clean sponge in light circular movements to get a smooth finish on grout lines. Wait 40 mins to clean tiles.
3. After applying grout, clean off tiles using light circular movements followed by diagonal wipes?

Any advise would be appreciated!

a lot depends on which grout you use,

good sponges is a must i use raimondi wash boy sponges

i think it's more a case of the more you do, the better you'll get at it, and develop your own style around the variations you mentioned. grouting is a bit of an art form, i know it took me a while before i was happy with the end result.

it's hard to determine how long after applying to wash off as there are a lot of factors in the equation, i.e type of substrate, room temp. type of grout, width of gap and type of tile. a ceramic will absorb the moisture out of the grout thus drying the grout quicker whereas a porcelain won't. it's always best to try a small area first and see how it dries. as above a washboy is good for cleaning and smoothing the grout lines

The timing will depend on the grout, the tiles and the atmosphere so you are better off just keeping and eye on it, you will soon find that you know exactly when to wash off.

I apply the grout and every 10 mins or so I check the grout in the joint where I started to make sure its not going off on me. When it is just starting to harden, give the tile and the joints a gentle wash off with clean water and a clean sponge, if the grout is pulled out of the joint then it is to soon and if you have to really scrub at it, it has been left to long.

Thanks, will try out the different ways then and find my 'style'!

 

[Lisamoore]

WOW, lots of variations then. Am using porcelain which I haven't laid beiore so thanks on the note that it will take a little longer to dry!

Thanks, will keep an eye on it then!

You must have a decent sponge, some are to soft and some are too hard. I find the hard ones end to pull the gorut back out if you are not careful. Not too wet too as obviously it just dilutes it and it can sag a bit,
