Power Grab Ultimate

I needed to attach an aluminum weather strip to a wood garage door in cooler weather ~40 deg F. Tried Liquid nails and clamps. After 2 days the stuff would not set and the bond failed. Power Grab set up in 24 hours, fully cured at 48 hrs. Awesome stuff! Will buy it again for sure.

This stuff is the bomb! I searched all over for a product that could be used to bond fiber reinforced panels to a welded steel garage door frame. This worked great under tough conditions. I can't speak to the normal time to set but, even in proper temperature conditions, I think this material will require clamping to hold on vertical surface.. I did not use it in anywhere near optimum (or even recommended) conditions. I used this on the frames of an exterior garage swing door and did so last April in record cold. Nights were in the high 20s Fahrenheit. Daytime highs of no more than 55. I could not close the doors due to the clamps. I do not recommend this application environment and doubt the manufacturer would either. However, this stuff dried to a tough, slightly pliable bond within 24-36 hours. Again, no idea of set time in proper conditions. I also applied the FRP to older steel with a significant patina of rust. I did use an angle grinder to remove a couple of sections of heavier scale, but that's it. This stuff grabbed tight. I got about 90 feet of medium bead per tube and used the excess for a variety of other applications including bonding plastic (polyethylene) and veneer to plywood. Great stuff!

I was bonding aluminum-to-aluminum and aluminum-to-PVC, both non-porous materials, so I did a lot of research on construction adhesives and found that most of them require at least one of the two mating materials to be porous in order to adhere properly. This one does not require that -- it specifically states that it will bond two non-porous materials. Cure time to full strength will be slower though. I watched a lot of construction adhesive review materials where various presenters try to determine the relative bond strength of different brands of construction adhesive. I found most of those experiments are flawed in one way or another. For example many just wait overnight, despite the fact that this adhesive and several others can take days to reach full strength. Other videos test with some rod cantilevered out of a glob of construction adhesive, ignoring the fact that that is not how you should use construction adhesive and most applications are going to apply compression and sheer forces (not "pull-out" leverage where an object is twisted out of the joint). I think all construction adhesives are about the same strength, and if the joint coming free is a major concern, you are probably misusing construction adhesive and should consider using mechanical fasters or epoxy.

Like a number of other reviewers, I found this very hard to use. As much as I squeezed the trigger on the gun, very little came out. I needed to soften it up, so I put the tube (without the metal gun) in the microwave for 30 seconds. That did the trick! Depending on how long you're working, you may need to re-heat it. Be careful - heat it too much and it might explode in your microwave. Also, as you use up the product, there is less to heat so you might want to cut back on the number of seconds.

Great adhesive. Case and glue are both thick. Flow is smoother if warm when applying. Some chalk guns will have problems. I like the larger temperature range for applying and short grab time. I applied several times at the low end of temperature range and it still worked well. In colder weather I had to prop glued items a few times. Warmer applications grabbed and stayed in place much faster.

it holds good value

Defective tube. Cut the nub. Poked through the foil. Tried in two guns. Could not extract any glue. Complete waste of money.

I bought this adhesive to attach faux brick panels to the side of the house. Panels were made of Styrofoam and I was attaching to a wood surface, the adhesive held great, no need for bracing, just pushed on to adhere, and it stayed.
