Forms quickly and works great for adding support where needed. Make sure to know how much you will need before ordering to make your project come together faster

Way too expensive for how much it produces

Very disappointed. Spent money on a product that didn’t work. Was supposed to expand twice or three times it’s weight but never did. Wasted money and time. Followed all directions to the tee.

Easy 1:1 mix. Read instructions, but for sure be ready to pour almost immediately. Expands at a somewhat surprising but manageable rate. Sets up hard! Not the fluffy can foam.

Others suggest the sparse instructions are a negative, but you’ve only got to READ and COMPREHEND the instructions given. Understanding how various 2 part mixes work is a plus.I used 1 pint each of A + B and employed a small mechanical paint stirrer with a variable speed drill to mix. It rapidly became homogenous and coffee colored. I could feel the heat building while I was pouring the final bit into the cavity I wanted to fill.I’d estimate that it produced approximately 2/3 cubic foot of foam.Temperature of cavity was 78° F. It seems obvious that the warm temp definitely contributed to rapid expansion and intimate volume.
