![]() ![]() ![]() Sacco says often when there’s a problem with concrete it’s because the environment it’s in is too moist, such as near the ladder of a swimming pool. Kingdom Products also sells a product that you can use for waterproofing. They can also use it as a finish coat around a pool for a pool deck where they’re applying a spray-down/knock-down finish.” “We sell it pigmented so they can do decorative repair with it. “They can do standard concrete repair with it,” Sacco says. It also works on veneers or ready-mix concrete surfaces to change or clean up coloring or add more life, Grogg adds.īart Sacco, president of Throop, Pennsylvania-based Kingdom Products, says his company’s Top Cap is designed for just about any kind of restoration work the customer may need. “The simplest application is using it in a spray or roll-on application on a textured surface to take the color back to gray or white while leaving the texture.” “MicroTop has many uses from tape-down applications and smooth topcoats to updating colors,” says Bruce Grogg, company president. It can also be true if it is something more complex, like a new stamping job.Īt its most basic is a product like Picayune, Mississippi-based Stone Edge Surfaces MicroTop, which can be sprayed on in thin coats. This is true whether it’s simply cleaning up the mess left by last winter’s freeze-thaw conditions or an unhappy color application. However, the result of resurfacing can be just about anything a contractor needs it to be. The color was achieved simply by troweling multiple colors of material together. Kingdom Products’ Rosalia Microtopping System was used on this kitchen floor and countertop, including the waterfall edge. That’s critical for the ultimate success of resurfacing.” It also does an adequate job removing oil, grease and other contaminants that could prevent a permanent bond. “That will take off any concrete that’s delaminating. “We really recommend a 3,500-psi pressure washer,” he say. This makes up for any potential problems that might arise through poor surface preparation or materials handling.įor instance, Owens says Quikrete recommends spending at least as much time in surface prep as in applying the actual product. Owens says research has continued in the development of polymers. This is a coating that can easily yield 9,500 psi.” “Then, you add the powdered cement and sand aggregates into it, and the matrix is being increased. “The resin alone can yield more than 8,500 psi,” he says. However, his company’s new GSPEC (Green Self-leveling Polyurethane Epoxy Cement) product goes well beyond that. He says a typical concrete job may have a tensile strength of 3,000 psi. Kummer agrees there’s nothing weak about these overlay products. ![]() As a result, the concrete will fracture before the bond to Re-Cap will break. However, continued research by Quikrete over the years led to the use of proprietary polymers in its current resurfacer, called Re-Cap, which has a bond strength that’s about four times the strength of the concrete itself. ![]() This will take the color back to gray or white while leaving the texture. Some overlays can be rolled on a textured surface. One, of course, is for concrete in need of repair. Scott Kummer of Los Angeles-based Green Chemistry Innovations (GCI) says there are several different reasons for using overlays. In a perfect world, every client would love every job, and the durability of every installation could be measured in decades. Installing an overlay is an affordable alternative to tearing out old and worn concrete driveways, sidewalks and patios and replacing them. All of these advantages are bringing them to the forefront of a contractor’s bag of tricks. However, that’s only one of the advantages these products offer. Concrete contractors have a similar option with overlays and an unsightly slab: The overlaid section not only looks better, but the chemistry behind today’s concrete overlays often create a much more durable surface than what was already there. However, sometimes a little bit of icing can go a long way toward redemption. Photo courtesy of Green Chemistry InnovationsĪ baker knows when there’s a disaster in the kitchen. It is as durable as terrazzo without the busy aggregate-look. Contractors use it to breathe new life into the lobby of this residential high-rise in downtown Los Angeles. However, the products today are much more long-lasting and hardier than those offered in the past. Concrete overlays are not new to the industry. ![]()
