Mark Wright: Where is the vapor barrier? Concrete will always sweat and the warm air in the room will condensate on the cold concrete. That foam will rot out.
Mark Wright: Who else cringed when he put the wet tool into the dry cement powder?
Robi Janez: aren't you suppose to put plastic vapoor wrap on the foundation wall or leave space for air ventilation which can be done with wood stud framing, then insultation to allow concrete walls to breath? alternatively have exterior 2 inch rigid foam insulation underneath water membrane and black tar on foundation exterior wall
Mikey Jimenez: That's gonna be one very expensive basement using so many materials just to insulate it. If no one is gonna live in the basement and you're only prepping it for entertainment, I would just paint the walls and put ceiling tiles, finish the floor and that's it. And only hang drywall wherever you are diving rooms
matt motta: no poly?
Myron Smith: What if the concrete wall is out of square or not plum
Phil Shiftley: At end of video ... Tom talks about installing a electrical box by cutting out some of the foam ... the romex wire entry on those boxes are in the top/bottom at very back. How do you get your romex in if the openings are buried in the foam? Cut out a much larger piece of foam? Could one use a power actuated gun with a washered pin to attache what looks like 1x4 furring strips?
Kay Brown: I did the condensation test twice on my basement walls in two different places. No problems. But I did that in the Winter. Does it really make a difference what time of the year you test for condensation on the basement walls since Winters tend to be drier than Spring or Summer?
TFAY Productions: I'd use a hot wire cutter
lazzyrj1: New homes are so easy to work on . Try this on a hundred year old concrete in a hundred year old home here in Chicago . Not so easy .
Motor rider: I remember waking up early when I was a little kid to watch this show
ObsessionPC: So you would cut into the insulation to fit a wall plug that then sits inside of the insulation...ok...Does that foam burn/melt at all?
Joe Swanson: "Now once I put it in the hole, it's going to expand." I think you're doing it wrong. Mine expands before I put it in the hole.
Big Guns Da Wiggla: What happens when you're hanging something, and you drive a screw through the romex?
_TriGalaxy_: There ya go. Just use an unguarded punch and hit it as hard as you can I mean JUST WACK on that thing that way when you miss it really hurts.
Ben Breeg: That guy got screwed on the basement water-proofing, his rebar is already rotting and eventually - down comes the crumbling rotten holes.
GrittyThumbs Doups: Run the adhesive vertical so that if water were to get in, it could trickle down. Applying the adhesive horizontal will allow the water to accumulate and mold.
giesen: The last butthole to finish the rec room in my basement did it like this (minus the rigid foam, just tar paper and furring strips), and I want to strangle him. Now I have to rip it all out and start again. Put a proper framed wall in front of the rigid foam. And tape the seams on your rigid foam.
gatewaysolo104: If your basement walls are sealed and dry, why not use standard framing with fiberglass insulation?
n00bBagHead: So let me get this straight first you need to wet the cement then lubricate the hole with a mist and finally just push it in the hole. Most excellent video.
