How many 4'x8' boards will 1 tube stick on a wall?

Looking to see coverage on board to wall and am wondering how many tubes I will need.
Asked by: John
1 tube per board. Yup. If you follow the directions on the tube it takes 1 tube per 4 by 8 board. The guy at home depot told us to start with 4 for our 10 , luckily we bought 6 but morning found us running for more. If you are putting it on a ceiling, use 1 by 2s to brace it in place until cured.

Will the foamboard contruction glue stick to painted concrete

Asked by: Myrna
Yes, but it MUST be thoroughly braced for at least 5 days and applied in copious amounts to fill the gap.

Does this product provide good adhesion between arch foam and a wood surface.

The replacement corbel is less than a pound vs 40-50 lbs if fabricated from wood stock.
Asked by: Hummerjock
Yes. I glued foamboard panels to wood using this with great results.

I used about 24 tubes of this on one project, so I'll share my experiences...First, it's a latex adhesive, not a classic liquid nails construction adhesive. If you have to apply thick, which I did in order to adhere to an uneven brick wall, then you can bet on a 5-7 day cure time. You need to brace it well during this period - it has very little grabbing power when wet. Once it dried, it worked quite well, but not everyone has a week, nor the inclination to brace a room full of panels, so buyer beware. Once dry, it has superior adhesion to the liquid nails panel product.

The instructions say to lay a bead 1 inch from all sides and then a bead every 2 inches. Doing this, you will get about 2 4 x 8 sheets per tube. Once the bead is up, support the board in place. The instructions say to use a mechanical fastener, i.e. screw, but that is of course not going to happen since you don't want to break the continuous vapor barrier. Instead, put something heavy, like a cinder block on the floor at the base of the board and then lean a couple 2 x 4's against the board at the top. The instructions state that the cure time is 24 hours. Trust the instructions and keep it supported for that long and it works great. One tip that I've discovered is putting a big dab or glob at each of the 4 corners really helps to hold it tight while it cures, so I suggest putting 4 big globs in each corner in addition to the beads every 10 inches. 2 boards per tube. Don't try to stretch it to 3 or 4 boards per tube or you will be one of the people giving it 2 stars and saying that it doesn't work. It works if you use it properly.

Rated 2 out of 5 by from defective batch of PL300? I bought a dozen tubes of this stuff for a renovation project I'm working on .... Used it to glue foamboard to cement. I noticed that many of the tubes had liquid in them, which was very unusual for caulk gun application type of product... but i needed to get going with the project and opened a tube that didn't exhibit the liquid in the tube sound. The first tube was good there was a small spurt of liquid while i was applying to the foamboard. The second had a bit more liquid but was managable. The third tube had even more liquid and was close to usuable! In fact i used the tube but got aboutbhalf the bead length advertized by Loctite $

Used this to install Insulfoam to concrete cinder blocks in my crawl spaces. Not sure what all the complaints are about, this product worked great. The foam sticks the concrete wall to the foam boards very well. The tubes should come in bigger sizes though, you can use an entire tube on one 4x8 board, they go pretty quickly. It does help to have a flat wall. I actually used a few breakable plastic wedges where there were gaps and some heavy weights to keep the boards tight on the bottom while curing. This adhesive is designed for foam, I wouldn't use anything else.

Rated 2 out of 5 by from Poor adhension This product will keep your foam board in place which is why I gave it 2 stars, but after 12 hours the product was still not set up. I removed the 2 x 4 holding my foam board in place and the foam board sprung back at me because this product did not hold my foam board. I'm going to return what I bought and just use liquid nails. I've done some reading online and it appears that liquid nails will be fine

Rated 5 out of 5 by from The RIGHT adhesive for job I have used about 3 dozen+ tubes to attach eighty 2" x 2' x 8' foam board panels to the cement basement walls. Wall preparation was important to get excess dust off the walls before gluing. I also laid a bead of caulk between each panel to make them water/air tight. Follow up with Great Stuff to fill any small gaps, and Tyvek tape to double seal all seems. The end result is something Mike Holmes would be proud of. It takes 24 hours to firm up before you should remove braces holding it flush to the target surface. I used expanding clamps in a number of areas when the wall was parallel with the ceiling rafters. When it is perpendicular, using a pile of boards at the bottom, and leaning boards up higher works really well. Clamps the tops too so they stay flush from top to bottom. Wood for leaning on the foam...pressure treated is heavier and gives a better hold... Foamboard insulation is awesome and this is the perfect product to get it installed without holes from nail/screw anchors. I laid it down pretty thick, and only got about 1 tube for 2.5 panels. Used the Milwaukee Caulk Gun to apply it quickly and evenly. Older tubes that sat on the shelves at Home Depot might get soupy inside (just the first ounce or two). If they are piled up high with dust and all beat up, pass on that tube and go for a new looking one.

Rated 1 out of 5 by from The smell is horrible Wow. If I had known the odor this puts off I would never have bought this product. It seems to be holding good. Directions say wait 24 hours to cure. Should say open all windows and use in the summer when opening the windows makes sense.
