Resin bound surfaces are a popular choice for driveways, patios, and pathways, known for their durability, permeability, and aesthetic appeal. However, like any natural material, they are not entirely immune to occasional imperfections. One such issue is the appearance of rust spots on resin bound surfaces, which can sometimes occur due to the natural properties of the aggregate used in the mix.
Why Do Rust Spots Appear?
The aggregates used in resin bound surfaces are sourced from natural materials such as pebbles, quartz, and granite. While these materials are carefully selected for their strength and appearance, they can occasionally contain small amounts of iron residues. Over time, exposure to moisture and air can cause these iron particles to oxidize, leading to visible rust spots on the surface.
When Does This Happen?
Rust spots are a relatively rare occurrence and often affect lighter-colored aggregates, where the contrast makes the rust more noticeable. While suppliers take steps to identify and avoid aggregates with iron content, it is not always easy to spot during the selection process. Despite rigorous quality checks, the natural variability of aggregates means that rust spots can sometimes appear after installation.
Is It a Workmanship or Material Issue?
The good news is that rust spots are not an indicator of poor workmanship or issues with the resin binder. The problem is inherent to the aggregate itself and is unrelated to the quality of the installation or the resin product used. Even with the best practices in place, the natural properties of aggregates make it difficult to entirely eliminate the potential for rust spotting.
Can Rust Spots Be Permanently Fixed?
So far, a permanent solution to rust spotting on resin bound surfaces has not been found. However, the issue can be managed effectively using specialist cleaning products designed to remove rust stains. These chemicals are widely available on the market and can help restore the surface’s appearance without damaging the resin or the aggregate.
Preventative Measures and Solutions
- Aggregate Selection:
- Once rust spotting is identified as an issue with a particular batch of aggregate, it is typically excluded from future use. Suppliers and installers work diligently to minimize the risk of rust-prone aggregates being included in resin bound mixes.
- Specialist Cleaning:
- Regular cleaning with specialist rust removal products can effectively reduce the visibility of rust spots. It is important to follow the manufacturer’s instructions to ensure the resin surface is not damaged during cleaning.
- Understanding Expectations:
- Homeowners should be aware that rust spots, while rare, are a natural characteristic of certain aggregates and do not compromise the functionality or durability of the resin bound surface.
Rust spots on resin bound surfaces are a seldom-seen issue that arises from the natural properties of the aggregates used. While not a defect in workmanship or materials, they can be managed with appropriate cleaning methods. At present, there is no permanent solution, but specialist cleaning products provide an effective way to address the problem and maintain the surface’s appearance.
