Quik-trak on slab question

Greg Durgin_2

I am hoping that The Wall can share some expertise/experience on a mud-room radiant panel floor job we are working on this week.

Rubber tubing installed in the 1980's has failed in a grade-level 4" concrete slab (with 2"rigid insulation below). We will remove the existing thin-set ceramic tiles and install Wirsbo quik-trak on the slab. The radiant "sub-floor" will be covered with backer-board and the finish treatment will be large ceramic tile laid in thin-set. The heat loss calcs work out fine.

How would you suggest we attach the quiktrak panels to the slab? Would a strong adhesive (like PL400) be sufficient? Powershots?

And how would you affix the tile-backer board (3/8") to the quiktrak (1/2")? Adhesive? Usually, with a wood sub-floor below the quiktrak we would just screw through.

Thanks for your thoughts.

I think I heard about a cool tool here on the wall

looks like a good excuse for another tool:-)

Trakfast

is the tool I have used.It works well in this situation and is cheaper per shot than a Hilti type.

Since the floor already has radiant I assume the slab is insulated below.I would attach the climate panel/quicktrack directly to the cement.The tile backer is than installed with thinset and more of the same Trakfast pins.

I did my showroom in much the same way and it worked out very well.

Thanks Paul and John.

That looks like a nice tool.

I have a hilti so can use some pins for both layers.

Yes John, there is insulation below the slab.

Thanks again for the advice.

Float babyyyy

We've done it with a thin pad underneath then floated the climate panels and covered with 3/8 plwood stapled to the panels to lock them together topped that with floating laminate wood and carpet worked great. probably not stiff enough for tile though.
