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.

Will adhesive be possible in winter crawl space about 10 degrees or wait till Spring?

Asked by: PAmtns
I insulated my metal garage door this time last year over a week period and it wasn't a problem. I don't know what the exact temperature was but I'm sure it was below freezing at times. The label on the product should specify a minimum temperature for it's use. Good luck.

PL300 10 fl. oz. Foamboard VOC Adhesive is rated 3.7 out of 5 by 40.
Rated 5 out of 5 by from Strong adhesive when it dries with no odor There really weren't too many options for securing rigid XPS foam to CMU walls. So I was pretty much forced to use this product. Well I must say that I am so pleased with all aspects. From the price to performance this product did not disappoint! The only drawbacks I experienced (and I hesitate to use that term) are that you must brace the foam to the wall for 12 hours to let the adhesive set up. Also if don't keep pressure on the foam at areas where it wants to pull away from the wall, the adhesive's initial grab strength is not strong enough to hold the foam tight to the wall. I experienced a couple areas where the foam pulled away from the wall 1/4" mostly due to some bad mortar joints and/or block alignment. Great product. Availability was hit-or-miss from store to store. And don't even bother trying to buy this at the other home big box store. They do not carry it in stock even though they have a nice assortment rigid foam stocked in-store. Explain that logic to me....

Rated 5 out of 5 by from PL 300 No odor, no problems and it comes out in a viscosity less then that of caulk, which i like for sealing foam board seams. I using this to close of the some gable vents and will be using it to add extra insulation, air and sound barrier to a 2nd story finished cape attic. This product will adhere to may substrates and foam with no issues. Keep in mind since it is thinner then caulk it comes out faster with the same gun squeeze and does not go as far if you do not make sure holes, seam and other gaps are large, but for the price. can you really complain compared to water based caulk or silicone? I found it worked very well for the application it was listed for and am going to get several cases soon to foam board over the R-19 I placed in the 2x6 rafters, insuring my 2nd floor is tight. Definitely a product I like.

Rated 5 out of 5 by from Worked well - for my application FWIW, this is the first time I have used the adhesive or the rigid foam insulation sheets so I read the reviews and followed the instructions for both products. In the process of finishing a basement with poured concrete walls, I opted for the additional insulation rather than regret it later. The walls are reasonably smooth and very dry so the only prep needed for the concrete wall was to descale the most ragged parts and blow off any dust. One review I read (another web site?) commented that he applied approximately 10 oz. one tube per 4’x8’ sheet and I found that to be fairly accurate. At $3.58 a tube why skimp? The only exception I noticed was that more adhesive was needed on the one portion of the cement wall that contained more ridges and indentations. When the insulation sheet is pressed against the wall the adhesive doesn’t spread as much so you have “dry” spots. As noted in other reviews, this adhesive isn’t extremely tacky so an adequate coating is necessary along with a temporary brace until the adhesive sets up a bit. In summary, prep well, use enough adhesive, brace the sheet and be patient enough to allow the adhesive to act. Do it right, do it once.

Rated 1 out of 5 by from Low initial grab This stuff is pretty much worthless if your trying to secure foam board vertically against sheeting. Its initial grab is close to that of toothpaste, which is almost non existent, so I had to go through and secure the foam board with screws until the PL300 cured, then I had to go back and remove the screws. I have used Liquid Nails Paneling and Molding Construction Adhesive and OSI F38 VOC Drywall Adhesive in the same type of foam board application before and they both have a much higher initial grab so no screws were required, just apply, place the foam board, press it firmly against the sheeting and move on to the next. I would stay away from this product and use either of the two aforementioned products.

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 $

Rated 3 out of 5 by from Inconsistent quality between tubes This product is just OK. It serves a specific specialty purpose, which it does well. Adhesives on foamboard (or any kind of polystyrene) can cause it to melt or decay unless you get the correct kind. This is the correct type. I used 3 tubes, and I found the 3rd tube to have "watery" spots in it. The others came out OK, but it is concerning that at least one tube was spotty. It has no smell at all, so the odor issue is good. (Very low VOC). I used it to adhere two boards together. I was making a sandwich for a small application to enhance insulation on an attic door. It works OK, but it takes a long time to cure. I found giving it 3 or 4 days to cure (in this application of back to back) was necessary for a good bond. It may not take that long when adhering to a different substrate.
