FAQs

Answers to your DIY concrete countertop project questions.

 

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.

 Z-Poxy: 2 part traditional epoxy sealer. Not recommended for first time users. High gloss finish, will significantly darken countertop.

 **All of our sealers are 100% countertop safe

Q. When can I snap off the forms?

A. The forms can be snapped off 24-48 hours after pouring.

Q. When can I start staining my countertop?

A. You can begin staining 4 days after pouring

Q. When can I seal my countertop?

A. If you are using the SiAcryl 14, you can begin staining 4-5 days after pouring. If you are using an epoxy sealer you must make sure the concrete is 100% cured. This can take as long as 28 days, however, on a slab this thick you will usually be safe after 10 days. 

Q. What are the Z-Counterforms made of?

A. Z-Counterforms are made of a proprietary mix of P.V.C.

Q. How do I make corners?
A. Corners are simply mitered with an ordinary miter saw. Any angle can be easily achieved.

Q. How is Z counterform removed once concrete has cured?
A. Because of Z counterform’s patented design simply pull the form forward and it will snap clean revealing a smooth edge.

Q. Does concrete adhere to the Z-Counterform?
A. No, concrete will not adhere to the inside of the Z-Counterform. The forms are polished to a gloss finish so the concrete edge will mirror the form when it is snapped off.

Q. Are Z-Counterforms re-useable?
A. No, because the tab under the concrete top stays in place when you snap off the Z-Counterform.
