When it comes to creating visually appealing and durable surfaces, resin bound has gained significant popularity in recent years. With it’s seamless finish, customisable designs and long-lasting qualities, resin bound surfaces are ideal for various applications, including driveways, walkways, patios and even commercial spaces. However, achieving the perfect resin bound surface requires more than just the resin itself.
Choosing the right surface for Resin Bound
The stability and overall success of a resin bound surface heavily rely on the underlying substrate. While resin bound is a versatile option, it’s essential to ensure that the base it is laid on is up to scratch, as any cracks will soon mirror on to the surface of the resin bound.
Concrete – Concrete is one of the most suitable surfaces for resin bound, its flatness and stability provides an excellent base for the resin and aggregate mixtures. Only requiring the use of a resin bound primer to ensure that its bonded and unable to shift away from the base. In order to remain SUDS compliant, we always recommend the use of porous no fines concrete, if not, ensure there is a suitable soak-away so no puddles can form within the Resin Bound system.
Asphalt – Asphalt surfaces can also be suitable for resin bound, but they must be in good condition. A smooth and stable can provide a solid foundation for the resin bound system. We recommend 50mm porous open graded asphalt in order to remain SUDS compliant, if not, ensure there is a suitable soak-away to avoid puddles forming in the resin bound system.
The Role of Resin Bound Primers
Resin bound primers are specifically formulated coatings that are applied to the base surface before the resin and aggregate mixture is laid. Their primary functions include:
Promoting Adhesion – Resin bound primers create a strong bond between the base surface and the resin-aggregate mixture. This ensures that the finished surface remains intact and resilient over time.
Reducing Porosity – Some resin bound primers reduce the porosity of the base surface, preventing excessive absorption of the resin binder. This can result in amore consistent resin-to-aggregate ratio during application.
Enhancing Durability – By providing an extra layer of protection to the base surface, resin bound primers contribute to the overall durability and longevity of the resin bound surface.
Prevent Moisture Issues – Resin bound primers can help prevent moisture from seeping through the base surface, which is crucial for maintaining the stability and appearance of the resin bound system.
Application of Resin Bound Primers
Surface Preparation – The base surface must be thoroughly cleaned, free from debris, and any existing coatings or sealants should be removed.
Primer Application – The resin bound primer is applied evenly using a roller or sprayer. The number of coats and drying times will vary, we recommend following the manufacturers instructions.
Curing – Once the primer has dried, the curing process begins. THis usuall takes a few hours, depending on environmental conditions.
Resin Bound Mixture Application – After the primer has fully cured, the resin and aggregate mixture can be applied to the surface. The primer’s strong adhesion ensures a secure bond between the mixture and the base.
Resin bound primers are a vital component in the successful installation of resin bound surfaces. They ensure adhesion, durability and long-lasting beauty by creating a solid bond between the base surface and the resin-aggregate mixture. When choosing a surface for resin bound, consider factors such as stability, porosity and drainage capabilities to achieve the best results. By understanding the significance of primers and their role in the installation process, you can create stunning and enduring resin bound surfaces that stand the test of time!
