Use and Care- Faucet Hole Concrete Countertop Knockout- Reusable Rubber Plugs:

• Secure Knockout in place with a small dab of silicone. You may also drill a small hole through the center of the Knockout, and use a washer and 2 1/2" long screw (2" screw for the 1 1/2" tall Faucet Plug size) to secure to the form. Apply Form Release (sold here) to the rubber knockout before pouring the concrete around it to make removal easier later.
• Removal- Prior to flipping over your cured concrete, loosen the edges of the Knockout with a flat head screw driver. Once the concrete piece is turned over, you should be able to push the Knockout free with your thumb and very little pressure.  In the event a rubber plug is difficult to remove from the concrete, the center of the rubber plug can be drilled out, giving the plug a little more flex so it can be pushed out easier.
• To Clean- Scrape off any hardened concrete and/or silicone from the Faucet Hole Concrete Countertop Knockouts.
