A concrete microtopping over radiant heat flooring system combines a thin layer of cementitious material with a radiant heating system beneath the surface. This method is commonly used to enhance the aesthetic appeal of floors while providing the benefits of radiant heating.What is Radiant Heating?Radiant heating involves embedding pipes or electrical elements beneath the floor. The use of Warmboard makes the process more efficient.Warmboard is a type of radiant heating system made of individual panels that are typically made of plywood or oriented strand board (OSB) with an aluminum surface. The aluminum layer serves as a highly conductive material to facilitate the efficient transfer of heat, thus providing efficient and comfortable heating to structures through the flooring.What is a Concrete Microtopping?A concrete microtopping, also known as a concrete overlayor microcement, is a thin layer of cementitious material that is applied over an existing concrete surface to achieve a decorative and revitalized finish. This technique is commonly used for interior and exterior surfaces and provides a cost-effective way to update and enhance the appearance of floors, walls, and other concrete structures.Duraamen’s Skraffino is one such microtopping. Skraffino is commonly used for renovating or restoring existing concrete surfaces. Skraffino is a cost-effective alternative to concrete replacement, providing a fresh and updated appearance to concrete and other substrates.Skraffino microcement is the perfect choice for creating a concrete floor with a radiant heating system. Skraffino is applied at 1/8 inch thick over the radiant heating system, thus allowing the efficient transfer of heat while providing a durable decorative surface.While Skraffino can represent the look of a polished concrete floor, numerous other decorative effects can be achieved through the creative use of a steel trowel, magic trowel, sponge, roller, or spray unit. Skraffino can be integrally colored, stained, or dyed, making for endless color options and a unique appearance for any interior design motif.Benefits of Skraffino Concrete Microtopping over Radiant Heat flooringOur Skraffino concrete microtopping offers several benefits when used in conjunction with radiant heat flooring systems.Thin Application and Even Heat Distribution:Skraffino’s thin application allows for more effective and uniform heat distribution from the radiant heating system, eliminating cold spots and ensuring consistent warmth throughout the space.Aesthetics and Design Flexibility:Skraffino offers a high level of design flexibility. It can be customized with various colors, textures, and patterns, providing a wide range of aesthetic options to suit different interior design styles.Versatility in Application:Skraffino can be applied to various surfaces, including floors, walls, and even furniture. This versatility allows for a cohesive design in spaces where radiant heat flooring is installed.Renovation and Updating:Skraffino is often used for renovating or updating existing concrete or flooring surfaces. It provides an opportunity to refresh the aesthetics of a space without the need for extensive removal or replacement of the existing substrate.Seamless and Smooth Finish:Skraffino can be applied to create a seamless and smooth finish. This not only enhances the overall appearance but also makes the surface easy to clean and maintain.Rapid Installation:The application of Skraffino is generally quicker compared to some traditional flooring materials. This can lead to reduced installation time and less disruption during the construction or renovation process.Cost-Effective Alternative:Skraffino is often a more cost-effective alternative to other high-end flooring. This is advantageous for projects with budget constraints.Durable and Wear-Resistant:When properly applied and sealed, Skraffino is durable and resistant to wear, making it suitable for high-traffic areas. Sealers enhance the longevity of the microcement finish and protect against stains.Compatibility with Radiant Heat Systems:Skraffino’s compatibility with radiant heat flooring systems allows for the integration of both technologies to create a visually appealing and comfortable living or working environment.Installation of Skraffino Concrete Microtopping over Radiant Heat Warmboard Flooring.Installing Skraffino over Warmboard involves several steps to ensure proper adhesion, even application, and a durable finish. Here’s a general guide:1. Warmboard Preparation & Cement Board Installation:Ensure that the Warmboard surface is clean, dry, and free from dust, debris, and contaminants. Repair any imperfections or irregularities in the Warmboard panels. Make sure the worm board is working and not leaking.Install cement board over the top of the Warmboard, completely covering the floor. The use of cement board is critical as it conducts heat well, unlike plywood.2. Priming Step 1:Apply Siderlath (fiberglass lath) over the top of the cement board. Embed the lath in Perdure E02 epoxy primer. Broadcast the primer with 30-mesh sand and let the E02 cure.3. Priming Step 2:Apply Duraamen’s CP1000 acrylic primer, over the cured Perdure E02 and broadcasted sand. It is crucial to use CP1000 with our Skraffino microcement to ensure the best results possible.4. Application of Microcement:Mix the Skraffino according to the product’s directions. Add an integral coloring like Colorfast Concrete Colorant if desired.Apply the Skraffino mixture in two or three layers totaling 1/8” think.Apply the first layer evenly over the CP1000 primed surface using a trowel or other appropriate tools. Work in small sections to ensure uniform coverage and do not exceed 1/16” thickness.Once the first layer is cured apply a second layer of Skraffino. Use a steel trowel to smooth and level the Skraffino and achieve the desired thickness of 1/8 inch. Ensure that the microcement is evenly distributed.A third layer of Skraffino may be applied if desired.5. Decorative Techniques (Optional):If desired, incorporate decorative techniques at this stage, such as color blending, texturing, or stamping. Follow the Duraamen’s recommendations for decorative additives and techniques.7. Curing:Allow the microcement to cure. Keep the area protected from foot traffic and other disturbances during the curing period.8. Sealing:Once Skraffino is fully cured, apply Perdure A03 Acrylic concrete sealer.Once the Perdure A03 is fully cured we recommend the application of a Polyurethane topcoat like Perdure U45 (matte finish) or Perdure U46 (gloss finish).The sealers and topcoats enhance the durability of the microcement, protect against stains, and provide a finished look. In high-traffic areas, a coat of epoxy and polyaspartic may be necessary.10. Final Inspection:Inspect the entire surface for any imperfections, bubbles, or irregularities. Address any issues promptly to achieve a high-quality finish.Note:It’s crucial to follow the specific product guidelines and recommendations provided by Duraamen and the Warmboard manufacturer.Working with skilled professionals experienced in Skraffino installation and radiant heating systems is advisable to ensure a successful and durable outcome.Where to buy radiant heat flooring suppliesSkraffino can be purchased through Duraamen.com or from one of its warehouse locations.
