Visual Guide: Preparation and Priming

See examples of substrate cleaning, priming, and the importance of proper surface preparation for resin flooring projects. Preparation is the key to long-lasting results in any resin floor install.

Step 1: Prepare the Surface

A strong, dry, and level substrate is critical for a flawless resin floor. Remove all previous floor coverings and thoroughly clean the base to eliminate dust, oil, or debris. Check for cracks, loose areas, or moisture—repair any defects and allow concrete to fully cure before proceeding. Surfaces such as tiles, screeds, or timber should be checked for movement, as instability may cause future cracking. For external applications, ensure that the area is properly drained and structurally sound to bear the intended load.

Always check substrate stability before applying resin. A poorly prepared base can lead to failures such as bubbling or delamination.

Step 3: Mix and Lay the Resin Aggregate System

The resin and aggregate must be combined seamlessly to ensure a permanent, attractive finish. Select your binder based on the stone type: use “Polirock” – Polyurethane Binder for White Stones for clear, non-yellowing results with white/natural stones, or “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits for coloured or dark aggregates. In outdoor drainage applications, an all-in-one kit such as “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin simplifies the process.

Blend the resin and hardener according to the provided instructions, then add the washed and dried pebbles or grits, mixing thoroughly to coat every stone. Pour the mixture onto the primed surface and distribute evenly using a trowel or screed bar, working in manageable sections. Target the required thickness for intended use: thinner for footpaths, thicker for driveways or car parks.

Maintain correct mixing ratios to avoid curing issues. Incorrect mixes can lead to soft spots, discolouration, or poor bonding.

Tips and Common Mistakes

Resin floors are durable but can be tricky on damp or unstable substrates. Always wait for surfaces to dry and cure fully. Avoid over-trowelling, as excess force can bring resin to the surface and increase slipperiness. Never neglect personal safety: wear gloves and protective clothing, and ensure good ventilation if working indoors. If bubbles or cloudiness appear, these may indicate moisture or incorrect mixing—remove affected sections and repair promptly.

Curing times vary with temperature and humidity. Cool or damp conditions will slow the process and may compromise adhesion. Plan your project during stable weather if working outside.
