Mixing Resin and Aggregate: Why It Must Be Thorough and Prompt

← Back to How do you put resin on the floor?

Properly mixing resin with aggregate and pouring promptly are the foundations of a long-lasting, attractive resin floor. Ignoring either step could lead to unsatisfactory surfaces, uneven curing or weak structure.

Why Thorough Mixing Matters

Mixing resin and aggregate carefully ensures each stone is coated with binder. This not only creates a uniform look but also locks the entire system together, preventing loose patches and weak points. Use a mechanical mixer or a cement mixer (for larger areas) to avoid dry spots, and double-check that all aggregate is evenly wetted before proceeding.

The Need for Prompt Pouring

Once mixed, the resin begins to react and will gradually thicken, restricting workability. Pour the mixture onto your prepared surface as soon as possible, and spread it evenly using a trowel or rake. Delays make the blend harder to level and could prevent the aggregate from settling properly, especially when aiming for a smooth, permeable finish such as those achieved with the Flowstone kit.

Practical Tips for Getting It Right

• Use the correct resin for your chosen aggregate (e.g., UV-resistant polyurethane for light stones, transparent epoxy for coloured pebbles).
• Ensure your substrate is clean and, where required, primed using a suitable product.
• Mix only as much as you can lay in the resin’s open time—work in manageable batches to avoid wastage.

When This Matters Most

If installing on driveways, footpaths, or public spaces, thorough mixing and prompt pouring are essential for the durability and safety of the finished floor. High-traffic areas demand a consistently bound surface, which starts with these steps.
