When Stamped Concrete Turns Dull
The use of an acrylic sealer is a popular choice for decorative outdoor concrete because they are UV resistant, enhance the appearance by forming a high-gloss, “wet look” and are highly water-repellent. Acrylic sealants can be readily purchased from local hardware stores, and are relatively easy to apply.
The disadvantages of using acrylic concrete sealers are that they are soft, less durable, susceptible to hot-tire pickup, and have a short lifespan. Depending upon climate and the amount of surface traffic, acrylic-based sealers can wear away quickly, unevenly. This exposes the surface to tannin stains, freeze-thaw, oil slicks, deicing chemicals, leaf stains, and road salts. All of which will slowly degrade the color and overall appearance of your stamped concrete surface.
When reapplication of the sealant is ignored, the glossy surface appearance will turn spotty and dull. If a concrete stain was applied to refresh a color, the susceptibility of the stain peeling becomes much greater. Thus, making the biennial application of a sealant crucial for the continued protection, luster, and aesthetic of the surface.
