Any roofing project, whether new or existing, will need preparation and a definite plan to implement. Lava 20 is a very user friendly product for waterproofing your roof space but here are come of the application guidelines that will ensure a successful result.
Flat roofing is gaining popularity in various types of buildings, but when it fails, it can pose risks to residents or occupants. Repairing flat roofs is essential, and it can range from minor patch repairs to complete renovations, especially for roofs that have exceeded their waterproofing system’s lifespan. When considering flat roof repair work, here are some crucial considerations:
Applying Lava 20 is a straightforward process that delivers professional-grade waterproofing with minimal effort. The first step in the application process is to prepare the surface. Ensure that the area is clean, dry, and free from any debris, dust, or old sealant. This preparation is crucial for achieving a strong bond between Lava 20 and the substrate, whether it’s concrete, wood, metal, or tiles.
Once the surface is prepped, you can begin with the primer. Applying a suitable primer enhances the adhesion of Lava 20, ensuring it bonds effectively and creates a durable waterproof layer. Use a brush or roller to evenly spread the primer across the entire area, paying special attention to corners and edges where water might seep through. Allow the primer to dry completely before proceeding to the next step.
With the primer set, it’s time to apply the first layer of Lava 20. Using a brush, roller, or sprayer, coat the surface with a generous layer of Lava 20, ensuring even coverage. For areas prone to movement or where joints are present, applying a narrow strip of Lava 20 and embedding a 100mm polyester tape into the wet coating can provide additional reinforcement. This step is particularly important for new OSB or plywood roofs, as the tape adds strength and flexibility to the joint areas.
After the first layer has dried, it’s time to incorporate any necessary safety features. For non-slip flooring, sprinkle silica sand onto the first coat while it’s still wet. This will embed the sand into the coating, creating a textured surface that improves traction and reduces the risk of slipping. Once the first coat is dry and the sand is securely in place, you can proceed to the topcoat.
The final step is to apply the second layer of Lava 20. This topcoat seals the surface, covering the embedded polyester tape or silica sand, and ensures a smooth, durable finish. Apply the topcoat evenly across the entire area, making sure to cover all seams and edges thoroughly. This layer not only enhances the waterproofing capabilities but also provides a seamless, aesthetically pleasing finish.
Allow the topcoat to cure fully before exposing it to water or heavy use. The curing time can vary depending on environmental conditions, so refer to the product guidelines for specific drying times. Once cured, Lava 20 creates a robust, flexible, and waterproof membrane that protects your surfaces from water ingress, ensuring long-lasting performance and peace of mind.
When compared to traditional flat roofing products like ‘torch-on felt’ and ‘fibreglass’, Lava 20 stands out for its ease of application. Unlike torch-on felt, which requires heating and specialised tools to melt and adhere the material, Lava 20 can be applied cold with a brush, roller, or sprayer, eliminating the need for dangerous equipment and reducing application time. Fibreglass, on the other hand, involves mixing resin and hardener and can be quite tricky to apply, especially in awkward or smaller spaces. Lava 20’s single-component system makes the process much simpler, offering a straightforward and efficient waterproofing solution without the hassle of complex tools or techniques. Its flexibility also means fewer issues with cracking over time, a common problem with more rigid materials like fibreglass.
In addition to its easy application, Lava 20 is also highly user-friendly when used for roof repairs. It’s ideal for patching leaks, sealing joints, or addressing wear and tear on older roofs. Because Lava 20 adheres well to a variety of surfaces, including concrete, metal, and wood, it can be applied directly over the existing roof material without the need for extensive surface preparation. Its flexibility allows it to move with the building, preventing cracks or splits from developing, even in extreme weather conditions. For both minor repairs and larger refurbishment projects, Lava 20 provides a quick, reliable, and cost-effective solution, making it a go-to product for both professionals and DIY enthusiasts looking to extend the life of their roof.
The application of Lava 20 is a simple yet effective process that involves surface preparation, priming, applying a base layer, reinforcing with polyester tape if needed, adding non-slip features, and finishing with a topcoat. Each step is designed to ensure maximum adhesion, durability, and waterproofing, making Lava 20 the ideal choice for protecting a variety of surfaces in both residential and commercial settings.
