Priming concrete floors

Why is it important to ensure proper priming of concrete floors?

Properly priming the substrate for resin floors has a significant impact on the quality, durability, and appearance of the topcoat. Using the right primer will reduce the substrate's absorbency and strengthen the surface.

We offer solvent-based, water-based, and solvent-free primers. This category also includes primers for unusual substrates, such as tiles or fresh/damp concrete.

FAQ: Priming concrete floors

When choosing a primer for concrete paint, we need to pay attention to two factors: 1. The primer's compatibility with the chosen paint/flooring resin. The technical data sheet for each flooring resin will provide information on the primers that can be used with it. As a rule, epoxy primers can be used under any flooring resin (epoxy, polyurethane, polyurea) and are usually a safe choice. It's best to choose system primers from the same manufacturer, as this will ensure no damage (assuming proper application). 2. The condition, quality, and type of substrate to be primed. We have a variety of primers to choose from, each tailored to the specific substrate's needs. While a dry, high-quality concrete substrate is no problem, fresh concrete or concrete subject to capillary action are a completely different story. Below, we present several resin primers and the situations in which they perform best. Epoxol Primer SF-P - a standard, solvent-free epoxy primer. Apply to dry, seasoned concrete substrates without moisture problems. Epoxol Primer – as above, but the product is solvent-based. Suitable for reinforcing absorbent, unstable substrates. Neopox Primer WS – a solvent-free epoxy primer for damp and/or fresh concrete (minimum 14 days old). Suitable for moisture that has penetrated the concrete from above, for example, from rainfall or frequent surface washing, if the surface has not been allowed to dry. Neopox Primer AY – a solvent-free epoxy primer that seals off capillary moisture, for example, in the event of missing or damaged subsurface waterproofing. Neodur Fast Track PR – a fast-drying polyurea primer, recommended where time is of the essence. Also suitable for use at low temperatures (minimum +5°C).

In the case of a wet subfloor, we must distinguish between situations based on the source of the moisture. Moisture from the outside, from above, refers to moisture, for example, from rainfall or from frequent washing of the floor and the inability to dry it. In such cases, we use Neopox Primer WS. Moisture rising from below the floor by capillary action, from the ground beneath the floor, when there is no waterproofing or it is damaged. In such cases, we use Neopox Primer AY.

With a few exceptions (e.g., Neopox Special applied to good-quality concrete "without problems"), priming the substrate for resin flooring is essential. The substrate should be primed for several reasons: - to close pores, which is particularly important for resin self-leveling screeds - to equalize absorbency, which translates into greater resin performance and a uniform appearance - to improve the durability and adhesion of the entire system.
