Akona Concrete Form Release - Release Agent for Forms, Tubes, Sculpture Molds, Casting, and More, Liquid, Non-Stick, Non-Staining (1 Gallon)

Did what it said

I have used diesel on forms before. Works sort of but so smelly/messy. Reviews of this product are all over the map. I applied a coat on the T&G subfloor panels that I cut to the width I required. Both sides had a relatively smooth surface but with all the little crevices the concrete could have really caused problems. I used a sprayer that is meant for weed killer and such. Sprayed a generous coat and the temp was in the low 50's. An hour later, another coat. The next day I had to chip the spilled concrete away from the ends of my forms (areas where I did not use the Release Agent, which took about an hour each. Since the one run was 34 feet long and a foot high, I was concerned of the forms buckling outward. Before the pour, I packed sand in the gap between the forms and the soil, worrying about my form design failing in catastrophe, only to cause grief during this removal process. Now I am trying to remove the forms and am afraid I will need to dig out the length of the run to get the forms to release. Good news. Once the ends were no longer constraining, I could sense an ever so slightly movement of the form but only upward...no room outward. As you might be able to see in the photos, the 34 foot long form slipped upward. This was only possible because I used this Form Release product. Had I not used it, I suspect I was going to need to dig a significant portion of this out with a pick axe and shovel. I was dreading that possibility.

Works very well. I used it on a wood mold used to make concrete planter pots.

The product requires a slightly thicker coat and must be let cure longer than the last product I used, however, overall I am very pleased with this product.

Did not work for concrete stamps... Not even remotely close to release powder.
