![]() Let the Pros at Hard Rock Concrete Coatings Help With proper installation and maintenance, overlays are extremely durable and can last for decades, even in harsh climates. Common mistakes are failing to clean the concrete properly or to profile it adequately. Another factor is the preparation before applying the overlay. As mentioned above, if the underlying concrete is severely damaged and cracking, it is only a matter of time before any concrete resurfacing also cracks. The key factor in the longevity of an overlay is the quality of the surface it is applied to. Cement overlays can also be applied indoors, adding a modern texture to walls, fireplaces, and other surfaces. Other types of overlay methods include microtopping, spray-down, and self-leveling. Stamping an overlay, for example, can create interesting textures with the finished appearance of stone, wood, brick, tile, or slate. If you have standard, dull grey concrete, you can apply an overlay to spice things up. Whatever is causing the concrete to crack or surface up is going to have the same effect on the concrete overlay.Īnother reason you might choose to resurface your concrete with an overlay is for aesthetic purposes. It’s important to note, however, that if the concrete is cracked or uneven due to surfacing up, these are symptoms of bigger issues. This is a much more affordable alternative to completely redoing the concrete. For smaller, cosmetic flaws in the concrete, a thin layer of concrete can fill in and smooth out the imperfections. One way these overlays are used is to repair existing damaged concrete. With such a wide range of products, there is naturally an equally wide range of applications, and you can select the blend you need for your desired look, texture, or purpose. The polymer is a key component, as it is the magic ingredient that helps bind everything together and makes the overlay stick to the underlying surface. There are many different manufacturers with varying products, each with a proprietary blend of portland cements, aggregates, polymer resins, and polymer additives. When it comes to concrete, an overlay is simply a thin coating of concrete applied to a surface. Let’s take a look at what concrete overlays are, how they can be used, and how long they last. Over time, exposure to water, freezing, and other harsh conditions can start to break down the surface of the concrete, especially if it is unsealed. m² of floors and overlays.Our concrete patios, driveways, and sidewalks take a beating, and if they’re looking worse for wear, a concrete overlay could be the solution.Īlthough concrete is a very durable, tough material, it is also very porous. Reduced long term floor maintenance costs.ĭuring our more than 25 years’ experience we have casted more than 20 mil. No detrimental effect on shrinkage, curling is eliminated This also means there are no joints to fill or maintain. ![]() ![]() Improved abrasion resistance due to inherently reduced crazing and bleeding.įor bonded overlays on situ cast concrete, there are only heavy armored steel joints (with no or very limited openings) that eliminate the problems with joint edge rupture. No risk of failure due excessive curling and crackingĬost competitive solution while also providing higher performance due to better design materials and executionĮxcellent overall impact resistance of the floor due to the smart steel fiber reinforcement overlay design Factories / Distribution buildings - Refurbishing floorsĪ much better usage profile than traditional overlays.Typical applications of overlay solutions include finishing layers on prefabricated elements, or casting another layer at damaged industrial floors in facilities such as: These include both bonded and unbonded overlays for use with or without floor covering.Īs in all PrīmX installations, we use PrimeQuality, our online quality system used to ensure perfect quality and real-time project monitoring. Several variations are available depending on the needs. Our long-term experience in design, execution, and the engineered shrinkage properties of the PrīmX Overlay solution results in less cracking and helps overcome most of the common on-going maintenance problems. PrīmX system features high amount of evenly distributed steel fiber reinforcement and special anti-shrinkage, anti-cracking additives allowing creation of ductile, seamless concrete that is so strong it does not need traditional steel rebar reinforcement. This means the floors have the lowest possible maintenance cost, lowest damage to equipment, best productivity, best serviceability and greatest long-term value. Our Overlay solution is a reliable, non-curling solution, ensuring smooth, flat and durable surfaces with minimum or no joints. Traditional concrete overlays are extremely prone to cracking and curling, far more than other concrete structures. PrimekssLabs Concrete Research and Development Center.
