What Does It Cost to Seal a Concrete Base Before Resin Bound Gravel?

Sealing your concrete base is a vital first step before installing resin bound gravel. It protects your new surface and contributes to a professional, long-lasting finish—yet it’s a modest investment compared to the overall project.

Why Seal a Concrete Base?

Concrete is naturally porous and can absorb moisture from the ground or atmosphere. Using a purpose-made sealant, such as Resinstone methacrylic resin, helps block moisture ingress, minimises the risk of surface bubbling, and strengthens the adhesion of subsequent resin layers. This step safeguards the base from oils, chemicals, and weathering.

Typical Costs and Coverage

Sealing concrete generally represents a small portion of total resin bound gravel installation costs. For example, Resinstone comes in 5kg or 10kg sizes, and guidance is provided for surface coverage—letting you accurately calculate requirements based on area size. Material costs typically range from around £30 to £60, varying with thickness and surface condition.

How to Apply for Best Results

Ensure the concrete is dry, clean, and free from dust or loose debris before application.
Apply the resin evenly using a roller or brush, following product directions for drying time (usually under 12 hours for Resinstone).
Once sealed and cured, your concrete base will be ready to receive resin bound systems such as the Flowstone Complete Permeable Floor Kit.

When Sealing Matters Most

Sealing is crucial if your base is exposed to frequent freeze-thaw cycles, heavy traffic, or standing water. Proper sealing prevents premature deterioration, reduces future maintenance, and supports a flawless resin gravel finish.
