Resin-bonded and resin-bound flooring sound very similar, so it’s no surprise that people often mistake them for being the same thing. Often, they are incorrectly used interchangeably. However, they are in fact completely different resin flooring systems, so it is important that you understand the differences between resin bonded and resin bound.
While both resin bound and resin bonded systems share similar features, in that they both use resin and aggregates to form the surface, there are a couple of key differences between resin-bound and resin-bonded systems that you should be aware of.
Application
One of the key differences between resin bound and resin bonded is the method used to apply it to a surface.
Resin Bound Application
In resin bound surfacing, the resin and stone are mixed together before being trowelled into place. This forms a smooth finish, with no loose aggregate.
Resin Bonded Application
In a resin bonded flooring system, the resin is spread across the prepared surface or base, and then loose aggregate is scattered on top. The majority of the aggregate will adhere to the resin, some will remain loose. This gives a finish that more closely resembles a loose gravel surface, but with less of the aggregate being able to move.
Porosity
The difference in application means that resin bound and resin bonded have different properties once installed and cured.
One primary difference between the two is their porosity. A resin bound system will allow water to pass through to the ground beneath. However, a resin bonded system is not permeable which means that rain water will not pass through. A resin bonded system will need to have drainage planned, and potentially a system installed to carry away surface water.
The primary distinction between resin-bound and resin-bonded flooring is that resin-bound flooring offers a smooth, permeable, and decorative finish, while resin-bonded flooring provides a textured appearance and is less permeable.
Aesthetics
The difference in application between these systems also gives a different look and feel.
A resin bonded finish will look more like a traditional loose-gravel surface. This makes it a good option for areas where the look and feel of a resin bound system would not be a good fit. For example, older properties or listed buildings will generally match the appearance of a resin bonded finish better than a resin bound one.
A resin bound system offers more options for decorative finishes. The seamless finish achieved with resin-bound surfaces imparts a sleek and modern aesthetic. This aesthetic versatility enables the creation of intricate patterns, logos, or colour gradients. Having a range of design options makes resin bound surfacing a great choice for commercial flooring, where branding is important.
Durability
The properties of resin bound and resin bonded flooring have an effect on their overall durability.
A resin bonded system is made up of partly loose aggregate, which means that some will be displaced over time. This can sometimes happen unevenly, which risks leaving the flooring area with a bald patch which needs to be repaired.
On the other hand, a resin bound system is much more durable. Because of its seamless finish, you don’t have stones displaced and it is also resistant to weed growth, frost and has UV stable colours that won’t fade over time. This makes resin bound much more suitable for areas where longevity and low-maintenance is a priority.
Cost
There can be significant differences in the cost of a resin bound installation versus resin bonded installation.
Typically, a resin bonded system will cost less to install than a resin bound system. This is because bonded surfaces require less resin and are laid to a more shallow depth. Whereas a resin bound system requires a greater amount of resin, and may take longer to install, therefore increasing the costs of materials and labour.
Although resin bonded systems will cost less to install, bear in mind that a resin bound system may last longer and require less maintenance which could work out less over the course of its entire lifetime.
Should I Choose A Resin Bound Or A Resin Bonded System?
Ultimately, the decision on whether resin bound or resin bonded is best will be a personal one. We believe that resin bound is usually the better option for surfaces that require vehicle use, are more durable and aesthetically pleasing for commercial or modern residential areas, and can drain surface water.
Here’s a recap of the advantages and disadvantages of both systems:
Advantages of Resin Bonded Flooring:
- High durability and wear resistance: Resin bonded flooring is renowned for its exceptional durability and wear resistance. Making it a reliable choice for high-traffic areas such as driveways, pathways, and commercial spaces
- Cost-effectiveness: The thin layer of resin and aggregates covers a significant area, making the most out of the materials used. The installation process of resin-bonded flooring is relatively straightforward and can cost less in time and labour.
- Quick installation process: The quick installation process is advantageous for projects that need to be completed promptly, such as commercial spaces that can’t afford extended downtime.
Limitations of Resin Bonded Flooring:
- Limited water permeability: Unlike resin-bound flooring, where water can easily drain through the gaps between the fully coated aggregates, resin-bonded flooring doesn’t offer the same level of water drainage capability. This means that in areas with poor drainage and heavy rainfall, water can pool on the surface of resin-bonded flooring.
- Prone to UV degradation over time: Resin-bonded flooring is susceptible to UV degradation over time, especially if it’s exposed to direct sunlight for extended periods. To mitigate this issue, applying UV-resistant coatings or sealants periodically can help prolong the lifespan of the flooring’s appearance.
Benefits of Resin Bound Flooring:
- Permeable surface for effective water drainage: resin-bound flooring has interconnected gaps between the aggregates, allowing rainwater to pass through and permeate into the underlying substrate to prevent water from pooling.
- Contemporary and elegant appearance: The seamless finish achieved with resin-bound surfaces imparts a sleek and modern aesthetic. The aesthetic versatility of resin-bound flooring enables the creation of intricate patterns, logos, or colour gradients.
- UV stable and resistant to colour fading: The clear resin binder used in the mixture is formulated to withstand exposure to ultraviolet radiation from the sun. This UV stability ensures that the colour of the aggregates remains vibrant and consistent over time, without the risk of fading or discolouration.
The Limitations of Resin Bound Flooring:
- Installation complexity and time: The process demands attention to detail to ensure that the surface is level and free from imperfections.
- Cost considerations: If the existing surface requires extensive preparation, repair, or levelling, additional costs might be incurred. Intricate designs or custom patterns can also increase the labour and time required for installation.
