Tips & Warnings
Use powder or liquid pigment for color. Add to concrete mix or sprinkle on while concrete sets.
Sealers do not always last. Some are not scratch-resistant, some are not heat-resistant and you must apply others periodically over time. None are totally stain-resistant.
The process of mixing, pouring, finishing and curing concrete is difficult and, if not done properly, can result in imperfections.
Pouring the countertops in another location and transporting them to the kitchen can cause damage. Concrete is heavy and can easy to drop. It can even crack while setting in place.
