Vapour Barrier and Drywall

[Hidyn]

Hi all!

I saw a few threads where I could have discussed this, but I didn't want to necro. Anyways-

My question is about moisture buildup between plastic and drywall if you line the inside of a room. I know drywall is a bad choice but my resources are a little limited.

Would I be better off to build a room inside a room, or can I go ahead and line the walls with Panda? How often should I peel it back and look?

Why not paint the walls with a paint like kilz first?

 

[Hidyn]

I've never heard of that before... But when I looked it up it seems like what you use on a wall that's already been wrecked, it didn't look like they had a product for preventing molds and mildew. Is it especially waterproof?

Kills is a primer that seals, and you're gonna want a primer anyway. If you go to a paint store, you can get little packets of mildewcide that they will add into any paint. I read somewhere that flat white paint is the most evenly reflective paint. I used the purple drywall (mold and fire resistant and only $3 more per sheet) in my room, primed it with kills, then top coated it with flat white paint with the mildewcide about 2.5 years ago and it's still in great shape, and my room yields great. It's much better than having panda on the walls.

what cali med sez... you can just use kilz on the wall. to seal it.
all it is, is a shellac that has white pigment added to it so it is water proof to a degree depending what you apply it too, and yes, the mildew packets are available and i recommend it if you use the sheet rock, down here the green sheet rock is the waterproof mildew resistant type... we call it greenboard.
becareful using kilz, the odors are very strong in an enclosed area and it lingers for a few days-week so let it air out it you can


what kind of wall do you have now?? depending on that... you can probably apply a few good heavy coats of the original kilz(not the water clean up type!) on the wall will do what you want and save the sheet rock money for something else

...and i recomend it if you use the sheetrock, down here the green sheetrock is the waterproof midew resistent type of plaster board.

I second this recommendation. Go w/ green rock.

I see a lot of people who build problems into their rooms. Building extra walls in a basement with prefectly good concrete is one of them. IME of course

ask yourself where the watervapor you barrier against is goin to go

That's exactly what I was wondering, seems a bad idea to Panda the walls because with temperature changes there's bound to be condensation between the plastic and the walls. I've just read elsewhere it's a good idea.

The advice here seems much more sound to me, though!

The room is in good shape, except for the carpet, which I intend to rip out. I think I'll replace the outlets with GFCI protection and I've got smoke alarms as well as a fire extinguisher, but I'd just hate to have to rip down drywall that's got nothing wrong with it.

A fresh coat of paint sounds like an excellent plan, and while the greenboard style stuff is, I'm sure, worth the money, I'll hold off on a full reno until the paranoia settles in.

Thanks for the valuable input!

so what are the walls made of now?
sheet rock?

if so you paint the existing walls white,
no panda needed then

my current grow room has painted rock, Ive never had any issue with mold...
except on big phat budz
if you think the rh will be a prob hit it with a good coat of kilz

I think it's sheetrock... It's gypsum based drywall?

I'm not really sure. I'm having to teach myself some carpentry skills.

Let me grab my hammer (With the price tag still on it) and I'll go have a closer look!

sheeet man, if there's already rock on the wall i would hit it with a couple of good coats of kilz, if your really worried about mildew use the mold additive, its about $3 a packet and i think its called M21 or something like that,
put it in some cheep latex paint and lay that on as a 1st coat, there's a fair amount of work involved with putting in new rock not to mention the $$ that would be better spent elsewhere

^^^ yeah that ^^
