Answers to your DIY concrete countertop project questions.
Q. What products do I need? Do you sell a kit with everything?
A. Since every job is so different, all products have to be ordered individually. To help you figure out what you might need, we do have a Product Guide and Information Page.
Q. What is the difference between the Z Liqui-Crete add mix and the Z Counter-Pack add mix?
A. The difference between the two is the consistency of the mix. The Liqui-Crete is designed to use slightly more water, giving you a more flowable mix that will flow throughout the fiberglass mesh reinforcement. If you are using a more traditional reinforcement such as welded wire mesh, you will be better off with Counter-Pack. Both will achieve about 7500psi @ 28 days.
Q. I ordered a Sink Form but I don't see it in my shipment. Does that ship seperately?
A. The Sink Form will come in the same package as the Countertop Edge Forms.
Q. Which sealer should I use?
A. Z SiAcryl 14: Easy to apply penetrating sealer. Satin finish. Will not alter color of concrete or leave residue on concrete surface. Z Countershine Polish can be added to increase gloss. Only sealer recommended for outdoor countertops.
Z Aqua-Poxy: 2 part, easy to apply epoxy sealer. Semi gloss finish. Will slightly enhance coloring of countertop without darkening. Put on mulptiple coats to build up thick epoxy look.
Z-Poxy: 2 part traditional epoxy sealer. Not recommended for first time users. High gloss finish, will significantly darken countertop. Will give you thick wet epoxy look.
