I can not tell a lie. I made a mistake and I think it is time I fessed up. Several month ago I built a subfloor for my theater. I used the technique outlined on the DIY Network site
. I used U-boats
to raise the base frame off of the concrete and layed OSB on top of the frame. Because I essentially was building a large drum, I put pink stuff in between the framing.
After completing the subfloor, I built a riser.
I looked great. The floor felt great under foot. Then doubt set in. Is insulation suppose to be on a basement floor? They did it on DIY network, so it must be OK, right? What if moisture get into the insulation? As you can imagine this thought process began to fester. I eventually posted a thread about this type of subfloor and the overwhelming consensus was it was a bad idea. Aaaahhhhhh!!!!
Plus there was the little known fact (at least to me) that you are suppose to build the riser after the room is drywalled. Oh well, I have finally given in and last weekend I began the deconstruction process.
Two positives will come from this. 1) a more moisture-resistant subfloor and 2) I can rebuild the riser after the room is drywalled. Heck, just call it a $200.00 learning experience
The plan now is to rip it all out. I am going to put down Dricore
or build a floor on top of Delta-FL
. Maybe the original floor would of worked, but the thought of soggy, moldy, pink stuff on the floor under my HT was just not going to work.
I may not get it right the first time, but I can promise you it will be right when it is done.Pearl #8: Build riser after drywalling.
Pearl #9: Put in a good moisture-preventing product onto the basement floor.
