Garage tile project
Hello everyone...
Long time lurker...joined up in 2012 and have learned A LOT about large format tile from the members here at the JBT forum...
I'm starting the prep for a 1025 s.f. garage. The porcelain tile is 8"X48"..the concrete surface of the garage is pristine(poured in 1968) and has a "honed" finish..
I have long straight edges..the MLT system..wet saws and "snap" type tile cutters..
The choice of mortar brands is plentiful to say the least..
Ardex brand is avaliable locally..X77 seems like a decent choice..
I have used spectra lock and fusion pro grout in the past with excellent results...planning on a 1/8" grout joint..

Any thoughts or opinions would be greatly appreciated...

Thank you all for taking the time to read this..

I would take one of your longest straight edges and check how flat the slab is. I assume it's clean of paints, etc if it's pristine.

Hello Davy...
Thank you for the response...
And...yes..clean of everything except dust...
15' straight edge and the slab looks very flat...

Davy 08-05-2018 04:11 PM

Yeah, with 48 inch tiles you'll want the slab flat, within 3/16 in 15 ft.

X77 is fantastic but pricey. I would not hesitate to use X5 as it is rated for large format with up to a 3/4in notched trowel at about half the cost.

I like Laticrete 4XLT for large format tile.

Is there a drain somewhere in this garage? Also the concrete must be porous so the thinset will adhere and bond. Wet an area and see if it absorbs or kind a beads up and pools. It does not need to absorb in 3 seconds but it should not take very long. My choice for poo is Laticrete tri lite. 30 lbs. bag is same coverage as a 50 lb.,great for big tiles and has a good pot life.

Thank you for the thinset recommendations...half price is a good thing...:)..
I will look into the availability of laticrete products near me...
I've yet to test the slab for porosity...will do that tonight...

Thanks again for all the info...

Any thoughts on the last course of tile that vehicles make first contact with when entering the garage...special trim piece made for this..?..

Good coverage especially at the edge. The metal would be a question for the other fellas here, maybe better safe than sorry. But my thinking would be it is rubber it will only break if your coverage is inadequate at the edge. My cost on the x77 would be around$900 +/- for the X5 it would be around $500+/- . I haven't looked at laticrete price list in a while. I use Ardex daily and mapei on occasion, if I am single sourcing. you could save another $100 if you went with mapei lft. I haven't used the 4LXT but if Kman uses it,it must be good. The trilite is great and true to it's name 30lb bags with the same coverage as a 50lb and super sticky you can't go wrong

Where are you planning to end the tile when it get's to the door? Will the door be closing on the tile or are you going to stop it so the door still closes on the concrete?

The left and right sides of my garage slab pitch very slightly towards the center, and the whole of it pitches slightly towards the door. Might want to check that. I'd orient the tiles so the long side runs to the door, water will tend to follow the grout lines.

Being in a snowy area I wouldn't use anything except an epoxy grout on that floor, I think it is going to fend off road salt and oils better than anything else.

I'd find a bull nose, either matching or contrasting, for that entry row.

If the Tri-lite is like the Pro-lite, it's a light weight thinset in the same size bag as a 50 pounder. Not half price but close to half the weight. :)

mark999 08-06-2018 07:38 AM

As stated by others that slab needs to be VERY flat for them big boy tiles. Most garages slope to the outside which is a good thing. The floor does not need to be level only flat.If you have a drain towards the middle you will have a bowl like slope which would need to be addressed.And any places that are out of intended plane by more than 1/8" in 10 feet will need attention. Measure from high point to high point. Trying to fix hills and valleys as you are tiling will result in major fustration.

Davy, Tri-Lite costs alittle more than pro-lite but it is great for its non sag ability and the longer pot life works better for lots of applications.

Hello everyone....
Just asked the missus about where to terminate the tile...looks like it's going past the garage door...about 6" past the door to the edge of the slab(outside..exposed to the elements)..
Bull nose is definitely an option...is their an option B..?
A Schluter product...that would hold up to a garage's intended use..?

Thank you all again for the wealth of information in such a short amount of time...

In my over analyzing mind I'd be leery of any square edged trims.

As the tires hit that edge I think there will be some force that will try to push the trim forward against the tile edge. Although the joint between the tile and the trim will be filled with grout Id be concerned that the joint will fatigue over time and the grout fail.

With the new exposure requirement you're going to end up with the tile outside and the tile inside expanding/contracting at different rates. Scenario: garage door closed, sunny day; the outside tile exposed to the sun will expand more than the inside tile that is shielded from the sun.
