Excellent stuff, very fairly priced!
I just completed insulating my 27' X 14" hip ceiling with the 2" Pink insulation board. I'm doing a ventless roof/ceiling so closed-cell was the only option. This adhesive worked GREAT! Yeah, some times it'll come out a little runny for a second but I wouldn't let that bother you. The whole tube won't be like that. MAKE SURE you put this on heavy. If you try and go cheap with this product it renders useless on a ceiling. My spacing was 24" by up to 14' runs. I'd use 1/2 to 3/4 of a tube on every run like that and this stuff held like a champ! I still had to use some 1X to keep it pushed up against the ceilings until it dried but once it did it was a rock! I'd use it again and I highly recommend it! That's coming from a retired house carpenter!

    Average grip and strong odor
    I used this to glue a piece of insulation to an attic door. Realizing it probably wouldn’t stay in place while it dried, I took the door off its hinges and used weights to assist in the process. I wouldn’t trust it to stay on anything vertical while drying - not without something holding it in place. The fumes from this adhesive have a very strong smell.

    Thank you for the feedback. You are correct. The PL 300 Adhesive does require temporary bracing or mechanical support during the cure process, especially with vertical applications.

      IT MELTS/DISSOLES THE SM FOAM BOARDS !!!
      I thought this is especially designed for foam boards as advertised, well..it is not. I glued SM insulation panels onto my garage doors and this adhesive melted/dissolved the boards where the glue was applied, see pictures. Very disappointing. I would have made a big case with Home Depot and the LePage manufacturer but unfortunately I cant find the bill and I cannot prove what I used was indeed this PL300. Be aware and do not buy this for this reason !

      Thank you for your feedback. We are so sorry to learn of your experience. The LePage PL 300 is a solvent based adhesive and works with all foam board insulation panels when used properly in most construction projects. However, garage doors can be a problem depending upon the door composition and possible exposure to direct sunlight. Please call our Technical Help Line at 1-800-624-7767 and ask for the “Application Specialist”. We would like to try and help you if at all possible. Thank you again for the feedback and we hope to hear from you soon. LePageProducts-HenkelCorp

        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 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.

          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 $

            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.
