There was a problem filtering reviews right now. Please try again later.
It's easy to use, just follow the simple instructions on the containers. 50/50 mix (stir each before mixing). I used two 16oz. plastic drinking cups to mix (it will get warm when you mix - when you can feel the warmth really well against your palm as you're mixing, it's ready to use).
I poured the mix on the basin and in the pump well (we made the mistake of not covering our fountain during the winter and snow / water created numerous cracks in the concrete). With a helper, we swirled around the mix along the entire basin and well. The product filled the cracks and began to turn white. In approx. 10-15 minutes (as stated on the instructions) it was dry. We let it cure for a few hours and then painted to match the rest of the fountain.
It worked perfectly. The product created a nice, waterproof bond. Paint applied easily and, no leaks! We don't have a pond but those with leaks in the plastic "tub" variety will benefit from this product.
The trial unit can cast many items which I highly recommend. Doesn't seem to take mica powder very well to color. Might need to add more than usual. Only dislike is its shelf life, wish it lasted a little longer after opening.
