Customer Questions & Answers

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.

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

PL300 10 fl. oz. Foamboard VOC Adhesive is rated 3.4 out of 5 by 27.
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 $

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.

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 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 2 out of 5 by from Takes too long to cure, not worth the extra cost I bought this to attach 2" foam board to the foundation walls in my basement. I expected it to take a few minutes to develop a little bit of tack and holding power, so I braced it against the wall and left it. Several hours later I came back, removed the bracing, and found that it still had no tack and the boards came right off the wall. What's the point of using this if it requires mechanical fasteners to hold the board in place? The walls were around 65 degrees, so it's not as if it was too cold to work. I switched to using standard construction adhesive, half the price and works much better.

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 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.
