Length - 02:58 A small yet important tool needed to make concrete countertops is 100% silicone caulk. Award-winning designer Fu-Tung Cheng shows us how to use caulk during the countertop mold-making process. He also discusses how to properly apply the caulk. One of the fundamental parts of concrete countertop making is the mold. Once the mold is made it is important that the edges and corners are rounded. To avoid having to go back and grind the concrete countertop edges after it has been cured, Cheng uses 100% silicone caulk inside the edges of the mold. The caulk is applied before any material is placed inside the mold. This material is available at any local home improvement center. The reason Cheng recommends only using 100% silicone caulk as opposed to other types of caulk, like poly-butylene or acrylic, is that these leak water and material. The 100% silicone caulk will form a water-tight edge surrounding the mold. After the mold is complete, start by applying the caulk to the corners of the mold and then down all the sides. Make sure that the caulk is smooth as any imperfections in the caulk surface will be reflected in the edge of the concrete countertop. Caulk can be difficult to work with so be sure to practice several times on scrap material before applying it to your finished mold.
