Review: Performed as expected - We used this product to pot some 8' fake trees. It was very easy to use and held the trees firmly. The directions say," Mix equal parts by volume of Activator & Base. Stir immediately for 10 to 20 seconds. Pour immediatley after mixed. Rise time is 60 to 90 seconds. That's pretty much how it went.
Review: Four Stars - excellent results
