I need to put up drywall along the concrete going down the basement steps. On the other side of that concrete is dirt and then the garage on top. So I'm not really worried about insulating that area.<br /><br />Can I just glue the drywall directly to the concrete and call it done?<br /><br />Or if not, can I glue firing strips up and then screw in the drywall?<br /><br />..trying to avoid having to blast nails into the concrete, or drilling to put in anchors.<br /><br />After the advice on the carpet thread, I'm going to let someone that knows what they are doing put down the carpet and go ahead and drywall and paint it first.

I'm no expert but,<br /><br />Liquid nails should work great for securing firing strips...just make sure you clean concrete well beforehand. I would no put drywall directly on the concrete due to moisture issues (you want to allow the concrete to "breath" so any moisture from "sweating" wont get trapped and turn to mold/mildew.<br /><br />-JMW

I would paint the concrete with dryloks first,to seal and pervent ant moisture problems in the future,i personaly would use the impact nailer or blast nailer on the stips.Its quick and easy just wear some ear plugs.

I agree with Ron G....... Get a Hilti or such & shoot the strips.....Good advice with the sealer, too!....JK

I'm with Ron also. Home Depot is now carrying a paperless drywall. Take a look at that to avoid any mold/mildew. Definately use furring strips and shoot them in.

Re: Glue drywall to concrete? UPDATE:Complete

I think you need an air gap between the drywall and concrete. Might also pay to use greenboard. <br /><br />I don't see any problems with the liquid nails other than its a mess to deal with later.

firing strips it is...<br /><br />will try gluing the strips and use just a couple anchors to help hold it till the glue sets.<br /><br />I'll put a piece of plastic up and then my drywall.<br /><br />thanks y'all :)

Tapcon screws work well to anchor things to concrete and block. You drill one hole and install the screw. It cuts it's own threads and holds tightly. Come in all sizes. Saves time over plastic anchors and lead anchors. Get 'em at Home Creepo or Lowes.

Might give that a shot fireship, reason I wanted to use as few shots from the .22 hammer, when using them in other spots in my basement, I've had mix results in getting the nail to sink to the right depth.

Re: Glue drywall to concrete? UPDATE:Complete

Yep, paint with dryloc and then liquid nail 2x2 strips to the wall. Do not use a vapor barrier because you want air to circulate and keep it dry and mould free. A small gap at the top and bottom of the sheetrock hidden by molding offset by 1/8" spacers will allow air to circulate enough to keep the mould down. <br /><br />I attached the 2x2 top and bottom each with one screw. Then pull away from wall and squirt in a few dabs of liquid nails.<br /><br />Check out how I did it in my basement here:<br /><br /> Basement Project

I have had that problem too Noel. If you sink a pin into the hollow part of the block it drives flush. If you hit the webs in the center of the block it don't recess enough. The Tapcons solve this problem. You still have to drill holes, but all of the fasteners will be flush with the furring strips.

Like fireship and mark said tapcons at top and bottom then glue or just tapcons,but like mark suggested i would'nt put up plastic, your just asking for problems.

Re: Glue drywall to concrete? UPDATE:Complete

BTW if you use Dryloc (and I really do recommend it) don't bother using a brush for the first coat like they say. It's like trying to paint thin concrete on the wall. I used cheap-o rollers after about half an hour with a big slop brush. It really does work well. Just don't roll it out thin. A gallon doesn't cover much, and if you spread it thin, you are just wasting the product and your money. Follow the coverage rate. Inspect for "pin holes" after rolling and plug with a paint brush.

Re: Glue drywall to concrete? UPDATE:Complete

Want to know my amazing trick for fastening wood to concrete? Unbelievable strength at less than a 10th the cost of tapcons. You'll have to translate my Canadianese to your 12 penny nail jive though.<br /><br />Predrill a 3.5" deep 3/16" hole with a masonry bit like the kind found in the tapcon packages. Go right through your furring strip into the concrete. Pick yourself up a few of these if you're doing a lot because you'll occasionally blow one on a tough bit of agragate. Try to keep the speed low to avoid overheating the bit.<br /><br />Then slip in a folded over piece of 7" long #14 copper, so you have two wires running to the bottom of the hole. Pound in a 3" common nail. It'll be fairly difficult to pound the nail so try to hit it straight.<br /><br />You may have to experiment a bit since nail diameters and 3/16" bits vary. It should take some serious walloping to drive the nail. If it seems too difficult, try just one piece of #14. <br /><br />There's a variation on this method which uses tyeing wire rather than copper. Unless you're talking about a wet location I never saw much advantage and the tie wire is a little tricker.<br /><br />Once you're set up, you won't believe how well these hold.<br /><br />If I were attaching those furring strips it would be with PL Premium to bare clean concrete. No need for a sealer to mess with adhesion. I have done PL styro to concrete, PL drywall to styro too. Always worked fine, but no wiring on the walls. :)

Re: Glue drywall to concrete? UPDATE:Complete

Paul, what is "PL"?<br /><br />Noel, BTW if you have Radon gas in your area, painting with a cement paint like dryloc will reduce the infiltration of Radon gas. Thats the primary reason I used Dryloc. Plus the basement also gets the benefit of reduced water vapor penetration. That helps reduce mold and the musty basement smell coming from behind sheetrock. <br /><br />Regarding the carpet issue, I spent many months researching basement floor coverings before deciding on the CVT (composite vinyl tile). The CVT from Armstrong is 90% limestone, 10% vinyl. Not the hardest tile around, but it does let water vapor pass through and that is why it is used on concrete floors in department stores, warehouses, office buildings, etc where concrete is sub-grade.<br /><br />Wife wanted carpet, but after doing our homework and talking to experienced floor covering professionals and installers, CVT was the way to go. At about 60 cents a sq/ft, it is very inexpensive. So the money saved can be put into nice area carpets that can be picked up and "aired out" once in a while to reduce musty smells. <br /><br />I missed the rest of your posts on your basement project, but if you are making additional living space, I strongly suggest against wall to wall carpet or Pergo type flooring. The pros indicated that laminate flooring will get moisture buildup that eventually will buckle the planks, even with a plastic barrier.

Re: Glue drywall to concrete? UPDATE:Complete

Mark, PL Premium is an extremely popular construction adhesive up here. It's a moisture cure urethane that expands a bit as it dries. You can't walk into a home centre or a hardware store here without being greeted by a rack of them. All professional builders use it and swear by it: it's really revolutionized the construction industry here because it's such a good product. You even see it being used a fair bit in boat building now.<br /><br />Unfortunately, a little googling shows that it's not available in the US. Liquid Nails would be your nearest equivalant that I can find.

Re: Glue drywall to concrete? UPDATE:Complete

Just wanted to let everyone see that a thread did actually end with a completed project :) <br /><br />Project complete, My bro-in-law is a taper and will come over tomorrow to do the first coat.<br /><br />Thanks to everyone that replied.<br />Ended up going with:<br />5/8" firing strips,<br />Liquid Nails and 1.5" Power Nails with green load. It turned out to sink it perfectly, 2 of them stuck out, and I was able to sink with a hamer. Then 5/8" drywall.<br /><br />Pictures:<br /><br />

Good grief I thought I was looking at my old staircase from my previous house in Oakville. Worked out fine for me. Looks good.
