Hi all,

thanks for the help so far.. need a little more.

I am kinda scared to go forward with the powder gun method to support the beams on concrete because of the water cracks that I just fixed along the walls. I know I am not using the gun on the walls, just the floor but I dont want water to start coming up from the floor..

I was told that liquid nails is a good product? if so, which one to use?

I am just creating a simple little room in the basement.

thanks so much in advance..

Different types for different applications. Read the tube. The liquid nails i have used was for paneling and drywall

I used the 2 1/2 inch nails in my power gun. Going through a 2x4 leaves about 1 inch penetration into the concrete. My pad is about 3 inches thick. That shouldn't cause cracks.

I know there are several different Liquid Nails to pick from. Is there one that will adhere wood to concrete?

I was told that there was one that would be good since it is just a basement room.

I have had mixed results with Liquid Nails. Mostly, it has dried out over the years and lost it's adhesive power. The other problem is that you probably have to use either treated lumber or redwood when in direct contact with cement. Treated wood does not take to adhesives like Liquid Nails very well. Might try to locate an adhesive made especially for cement/wood contact.

Thanks for your follow up on this Doyle, I am just scared that the nails from the powder gun will crack the bottom concrete and cause water damage.

Just spent the past weekend "hopefully" patching up the walls and water proofing them, don't really feel like water proofing the floor.

I would use the powder gun. I have refinished many basements and completed a host of other similar work over the last few years. Never once have I had a problem with the powder gun. Now, if you do not select the correct charge for the application, you are likely to run into problems with cracking on the surface. My experience is that the nail goes through so fast that the concrete has little time to think about cracking. Your job will hold up much longer with the powder gun.

I agree with others that it's best to use a powder charge with 2 1/2 inch nails to secure the footings. Where I live, the building code requires using pressure treated wood for the bottom plate of all walls, and Liquid Nails does not adhere well to it.

Liquid Nails "Heavy Duty #LN-901" claims that it will adhere wood to concrete.

Will liquid nail stick to green lumber? I need to glue 2 pieces of green southern yellow pine lumber together. It will also be nailed, but I need the extra holding power of the glue to hold the items together.

I would use both glue and PINS no longer than 2 1/2. When the pins hit rocks in the concrete mix it causes pop's, the top portion of the concrete separates and leaves a small hole. When finishing concrete the rocks end up below the surface and the top part is mostly sand and concrete mix that the pins can penetrate with no problems. The use of pins will not cause any leakage problems. Before starting, you should lay plastic on the concrete floor and tape the edges down and wait for a day or two. If there is moisture underneath the plastic you should seal the floor.
