Interior wall consturction

[nate379]

Does an interior wall put on concrete need sill seal?

I have no way to attach wall to floor other than gluing it down (liquid nails). Pex runs in floor and I can't run Tapcons in since I don't know where the pex is.

Got a line on a FLIR rental but it's $350... more than this little closet will cost to build!

hey i am doing the same thing right now. i have part of the walk in. see if i like it then i will probably disassemble and glue it. but if someone has some ideas.

i wouldn't think you'd need it on an interior wall. I used it on the exterior wall/foundation though.

Maybe use the liquid nails and PT lumber for the bottom plate? Is this in the basement? That might be all u need to keep the wood from rotting. Usually I think people but some sort of seal or gasket to avoid direct contact with the ground concrete and wood.

In the garage.

I used some 4" x4" x 1/4" steel plates with studs welded on them.
Glue them to the floor (3' apart) and then bolted the bottom plate to that.
It kept the plate slightly off the floor too.
Never moved in 5 years.

I would think that an infra-red thermometer would be able to locate the pex.If you were to power the heat down for a couple days,then up to "max", you should be able to sweep the floor and map the "warm" lines,which would be the pex.

Kind of but that gives a rough idea +- 6" or so. I have to know 100% exactly where before I will put holes in the floor. Last thing I need to do is go through a tube and have to bust up some of the floor to repair!

How about using decay resistant lumber like Bluwood or even light gauge steel framing?

for interrior walls you do not need it
for the walls around a bathroom I would at least use the
pressure treated stuff and do a sealing bead of something
along the bathroom side edge just in case you ever get a leak
or something in the bathroom. could save alot of headache

How about running a single course of block then building your stud wall on top of that? If you only have a 8-ft high space to build in, you will have some additional cutting to do with the studs, but it would solve both the potential moisture problem as well as the "hole in the PEX" concerns.

I think I'm just going to use pressure treat and glue to floor. Wall is to close off the boiler, water heater and water softener which are in a corner of the garage. They are getting pretty beat up from welding sparks, paint overspray, etc.

Dumb to have in garage, but common to do so here.

As already stated, sill seal isn't required for interior walls. Code does require (I'm familiar with commercial code, not residential) that any wood that comes in contact with concrete has to be pressure treated.
