DiamondKote®, a division of AMT Enterprises, LLC are concrete contractors based in Middletown, CT. Since 1999, our mission has been to beautify ugly concrete for our customers while saving them thousands of dollars in replacement costs. Generally speaking, it costs about half the price to repair and resurface concrete than it does to remove and replace it. In addition, the finished look can be highly artistic. In some cases, when the repair costs approach the cost of replacement, DiamondKote®, can perform this task as well. Our concrete treatments can range from a small residential stoop repair to a heavy duty industrial epoxy floor coating.

Why Do An Overlay?

Concrete, although a rigid and hard product, does have it's weaknesses. For starters, the concrete surface is pourous and can retain stains and moisture and often promotes mold and mildew growth. The porosity of concrete also lends itself to freeze-thaw damage called "spalling". Spalling is separation of the thin cream finish layer that lies just above the stone aggregate mix in the concrete. Expansion from freezing moisture blows apart this layer, it resembles flaking and peeling. Left untreated, it will continue deteriorating until it becomes a trip hazard and an insurance claim candidate. The DiamondKote® overlay system will protect both new and old concrete surfaces from this moisture penetration and freeze-thaw damage. The overlay will also create a stain resistant barrier that mold and mildew cannot root into, thus making it an easy clean up.

What Is The DiamondKote® System?

Common Mistakes

Stained and deteriorated concrete is ugly. A common mistake is covering it up with concrete paint. There is No Paint that will permanently bond to concrete. Please don't paint your concrete. It will always peel off due to weather, moisture, and traffic and will become a continuing maintenance project. Painting concrete will end up costing you more in the long run because paint removal is done by diamond grinding, chemical removal or sand blasting. All of which are very messy and expensive. Your only solution is a Cementitious overlay system. The DiamondKote® system bonds permanently and is resistant to traffic wear, weather, and staining. The only maintenance needed for DiamondKote® is periodic cleaning and Resealing every 4-6 years at a minimal cost. With proper care, your DiamondKote® overlay will last 40+ years!
