White concrete mix
Not my first concrete counter but first time using this product in white with the Z bullnose break away forms. Loved the product and ease of use. Easy to finish. Few recommendations to new users... Video says 3 Qts/bag. I'd advise 3.5 Qts/bag. Also, find a vibrater to can vibrate the entire counter as bubbles will try to rise but be stuck under the finish creating small bubbles under the finish. Also recommend a 24" rounded edge finish trowel for finishing.

Kitchen Counter pour
5 star!!! We recently built a BnB and decided to attempt pouring concrete countertops. This product and instructions, both on the bag and the videos their website, made the process seamless. We will be sticking with this product for the next build.
