How much grout

We are laying 18x18 tiles in 224sq. ft. room. We bought matching grout, but they only had 2 bags left and it is discontinued. Is that enough?

how big are the bags and how wide are your grout joints?

The bags are 25lbs. It's a product called Keracolor, it contains sand. We're laying porcelain tile. I'm not sure the grout spacing, 1/2 ? What do you recommend for 18" tile?

generally, the larger the tile the smaller the joint. 18x18 looks good with 1/8th spacing but it really is a matter of preference. Whether you want the tile or the grout to be the focal point. If you go with 1/4 or less spacing i think you should be fine coverage wise.

Is having sand in the grout a problem? Does the grout need a sealer after its dry?

Notlucky,

Grout joint width is a matter of preference, but the wider the joint obviously you'll use alot more grout. With sanded grout, you need to use a grout joint of 3/16" or larger. Isn't there a chart on the side of the bag? I have a box of Polyblend unsanded and it has a chart indicating how many square feet per pound will be necessary with various size tiles. I just checked out Mapei's website. Here's their grout calculator. http://www.mapei.com/MapeiAmericas/en/index.htm I ran the calculator using 1/2" grout lines and assumed the tile was 3/8" thick and the calculator says you'll need 39.51 pounds. You need to seal grout both sanded and unsanded.

two 25lb bags should grout about 250 sq. ft. of 12x12 tiles with 1/4 joints.
1/4 joints are big enough for your tile.
two bags are plenty.
good luck.

I would be worried that if the grout has been discontinued it might have been on the shelf for awhile and gone "bad". Nothing like trying to grout with boulders in your mix.

The other day I grouted a 290 foot floor of 18 inchers with 3/16 joints and I used about a bag and a half-- so your two bags should be fine for up to 1/4 inch joints remember with 18s you have more tile and less grout that with something smaller like twleves--

Hi Nancy,

18" tiles need a pretty flat floor to get all the sides to line up with each other and avoid lippage from one tile to the next. The smaller the grout lines, the tougher it is to stay away from lippage, unless the floor is flat. Before deciding on a grout width, you may want to check your floor for flatness using the longest straight-edge you have (a 10' piece of 1x4 or 2x4 works ok if it is very straight). Run around the floor and see how much air space is under the straight-edge when it's on the floor. The normal goal is to to have less than 1/4" out of flat over 10' in distance, with no more than 1/16" out of flat in any given foot. Your larger tiles will install easier if your floor is well inside those figures.

Groutlines up to 1/8" use unsanded grout.
Groutlines 1/8" and wider use sanded grout.

I'd recommend thinking about 3/16" to 1/4" width. I'm not a big fan of wider grout lines unless you're looking for a more rustic look. And before commiting to those discontinued grout bags, I'd recommend checking the date codes on them to make sure they aren't more than a year old? Old grout doesn't work so good.
