Product Description:
  • Single 8' length of the Flat Square Edge Form that was been factory cut to make it bendable, up to as tight as a 6" radius!
  • Creates a 2 1/4" height edge to the in-place concrete countertop.
  • Easy to set up and use, for both professional and DIY.
  • Tip- Once this bendable edge form is installed in place, use electrical tape to cover over all the 'V' notches to seal them up and keep the form water-tight.
  • These Countertop Forms are designed to be attached to the cement board, which is screwed onto the top of the cabinets.  The Countertop Forms are simply snapped off when the concrete is cured, leaving behind the decorative edge countertop surface.
  • The only difference with this bendable form is that you will cut your cement board to the radius needed, and then install this bendable form around the curve.
  • Please watch the video below for a quick demonstration how to use the Forms:
    • Step 1: Attach cement board to the top of the cabinetry.
    • Step 2: Cut the Countertop Forms with a miter saw, and screw in place onto cement board.  Tape the outside of each joint with duct tape to ensure a water tight, and tight joint.
    • Step 3: Place Back-Wall pieces across the back of the countertop area (6 Back-Wall pieces (8' long each) are included with each box of Countertop Forms.  Back-Wall pieces create a back edge to allow a screed to be run across the concrete, creating a smooth, flat countertop.
    • Step 4: OPTIONAL- Cut a 2 5/8" hole in the cement board for each faucet hole needed, and insert the Cast-in-Place Faucet Knockouts (sold here in a 2-pack) into the hole.
    • Step 5: OPTIONAL- Create a hole for a sink, if needed. 
      • For an under-mount style sink, cut a hole in the cement board to fit the sink into, use the Cast-in-Place Sink Form (sold here) to attach to the sink itself, and place the sink into the cement board. 
      • For a drop-in style sink, the easiest way is to cut styrofoam to the size of the hole you need for the sink to fit into, place onto the cement board, and later when concrete is cured, remove the foam and cut out the cement board so the sink will drop in.
    • Step 6: Fill form with concrete.  Pack the concrete into the Edge Form to remove any large air pockets, and vibrate the Edge Form with a palm sander or other vibration source.  Poor vibration will result in a large number of voids in the concrete edge- ranging from small pinholes to larger pea sized holes.  Sometimes this look is sought after, but if it's not, make sure to vibrate well.
    • Step 7: Allow concrete to cure (usually a few days).  Remove and tape from the joints.   Sand off any excess concrete from the top corners (where concrete meets the Countertop Forms) with a Diamond Sanding Foam Pad (sold here) or a Flexible Diamond Sanding Strip (sold here).
    • Step 8: Remove Countertop Forms by simply pulling them away from the concrete, which will snap the Edge Form off, leaving the concrete countertop.
    • Steps 9,10,11... Concrete can be stained (stains sold here) if desired.  Concrete Countertop Sealers can be applied once the concrete is dry (sealers sold here).  


Q. What are the Z-Counterforms made of?
A. Z-Counterforms are made of a proprietary mix of P.V.C.

Q. Will the Z-Counterforms warp from the concrete?
A. No, forms are approximately 3mm thick to ensure a stable form even after the concrete is poured.

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

Q. Does concrete adhere to the Z-Counterform?
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.
