I'm going to tile my house and going to use 20" and 6" tile pattern. With this pattern, do I need to start in a specific place, or can I start in the bathroom and work my way down the hall through the kitchen and dining rooms?
I think the most important room should have the pattern centerd but you also want to consider all areas so you don't end up with a real lopsided look down the hall or 1/2" strip in front of the tub. You just have to do the homework.
With that big a tile you need to do some research to see if that floor will even be able to be tiled. Not all floors without some extra work can be.
There can be 0 floor deflection in tiles that big, There needs to be at least 1-1/8 subflooring and underlayment.
There can be no partical board or 1/4 underlaymant.
I agree that the main room should be considered first. Maybe I'll lay the pattern out through most of the area to be sure. Also it's a concrete slab that I have so I assumed that I didn't need an underlay. Am I wrong?
Sealant will do nothing more then stop material from falling in the crack.
If your going to install tiles that big then there's a very big chance it will crack right where that crack is sooner or later from movement. http://www.schluter.com/media/articl...e_floor_us.pdf
