Have not posted here for quite some time, but wanted to share a recent experience using automotive antifreeze/distilled water in my 1200 ft shop in floor heat. I have not touched the system since installed 13 years ago. With all the warnings against using ethylene glycol, I was afraid of...

Quick update... So far I have had no further problems, even with dragging the slow blower w/chains across the floor, scraping snow & ice off, etc. Looks like i simply parked on the material a little too early. I do agree with the reasoning of using a primer (which I did not), but if the...

again, thanks for replies. I will see how it goes after a few weeks and report back. With any luck it is just a spot-thing related to parking on it too soon. I will be a very happy guy if that is all it is!! Otherwise, I may be testing out the diamabrush surface remover disk next spring...

nope, no primer.

Hey MN, I am here in Mpls, and my floor was just like yours. Follow the above advice for the crack with chasing it and fill. For product, I tried several. For cracks and holes not very deep, I like the Rustoleum branded patch kit for about $20. It is somewhat self leveling and does a nice...

By no means a pro here... just look at my previous post :( I used a diamond cup wheel on my 4" grinder, and it will really tear the concrete down. You could get one for a 7" grinder and do the bad spots by hand. Be sure to keep it flat!! One of our area home depots had a floor machine with...

very nice, looks like a job well done!

Thanks for the reply. I had a brain-fart on the moisture test, which i did NOT do. With the dehumidifier running, I was not pulling much water out of the air, so thought I would be in good shape. I will cross my fingers that it is not moisture, and I drove on it too soon... But something...

Hey All, It has been quite a while since I have been on the Forum, and from the looks of my new floor, I should have spent a little more time here... Here's the story: My first floor experience was putting down Rock Solid on my new shop floor a few years back. Concrete was new, just did an...

you just never know what you might learn on the Garage Journal!

Interesting point... Since he cannot add more pex, is there another heat source that could work more effectively in this situation? Although it sounds like the system is keeping him warm, maybe just run it and live with it? I suppose it may just cause a little more strain and energy use from...

I have a floating slab, and no insulation directly under the "footing" of the slab. I may be getting some heat loss from under the slab perimeter. If so, it may make sense to lay the 4ft insulation down along the foundation as I mentioned above... I will see how it goes the rest of this...

Agreed with above posts. I think you will not be happy with fuel bills trying to heat your garage in MN 24x7 with non-insulated walls...

I should note that there is 2" XPS (R10) foam under the slab and up the side of slab and 9" block (which the tin in the pictures is covering). I have read articles where some will dig down to bottom of slab, and out from the bldg 4ft, laying XPS foam flat in the trench. The idea is that the...

This is my first winter with radiant heat, and am trying to determine what level of heat loss can be expected from the slab? My system seems to run efficiently and is not circulating very often, even with our recent -12 F cold snap. I have been keeping my slab temp at 60 degrees, which keeps...
