Correct Adhesive For Garage Floor Tiles

[DarkSource]

I am planning to put down ceramic tiles on the garage floor (concrete slab), but want to insulate the floor first using 20 mm Marmox multi-board. What type of adhesive should I use for the tiles on top of the Marmox, given that it is a garage floor and will need to stand the weight of a car? I am proposing to use tiles that are 600mm square.
Many thanks in advance!

I would be more concerned about using 600x600 CERAMIC tiles on a floor and point loading issues than tile adhesive

You've got to be looking at porcelain at least.

Yes, you are quite right, porcelain tiles would be (much) stronger than ceramic. But would porcelain be good enough? If not do you have any recommendations for doing a tiled, insulated garage floor on top of concrete?

I'd be looking at a grade 5 as in heavy commercial traffic and getting rid of the marmox, as mentioned there is point loading on the marmox.
What does a car weigh...1 ton.

Remember that even though the adhesive may have set sufficiently to walk on, with a Portland cement based adhesive it will be several days (weeks?) before it will have sufficient strength to drive over. Some adhesives are based on another type of cement and reach there full strength much quicker. Someone else may have better information on this.

Nearly all adhesives will take 2-3 weeks to cure properly.

From Ray's place, porcel-thin, about 6 hours are being tiled with TileMaster setaflex.

Thanks to all for your help!
However does anyone have an answer regarding an insulated garage floor? From the replies, I'm sure I can choose tiles and adhesive that will be strong enough if laid directly onto concrete, but I need a solution to insulate the floor as I want to use the garage all year round. I could use celotex and then put loads of screed over the top, but this would raise the floor by about 10-15 cm, which causes allsorts of other problems and isn't an option. From other forums people have suggested ditching the insulation and just using a space heater. This doesn't meet my requirements of a room that is easy to keep warm all year round i.e. well insulated with a couple of radiators. Surely someone has done this before? I can't believe I am the only person to have thought of this.
Kudos to the person who has a solution!
