Acrylic floor paints should not be applied to newly laid concrete or screed until the substrate has sufficiently cured and dried. Residual construction moisture can lead to adhesion loss, blistering or patchy drying. As a guide, concrete should be allowed to cure for a minimum of 28 days, with moisture levels verified where conditions are uncertain. Surfaces must be clean, laitance removed, and any curing compounds mechanically eliminated. Where porosity is high or inconsistent, a suitable concrete primer should be used to regulate absorption.

Dense or power-floated concrete presents limited mechanical key and can significantly reduce adhesion if not prepared correctly. The surface should be mechanically abraded, diamond ground or shot blasted to create a uniform, open texture. Acid etching alone is rarely sufficient on tightly closed concrete. All dust and debris must be removed prior to coating. On very smooth substrates, the use of a compatible primer is strongly recommended to improve bond strength and ensure more uniform film formation.

Acrylic systems are UV stable and suitable for external use on concrete and similar mineral substrates where light to medium traffic is expected. They offer good colour retention and are appropriate for pedestrian routes, light vehicle areas and general refurbishment. However, they are not designed for constant heavy traffic, high point loading or areas exposed to prolonged standing water. Adequate surface drainage and thorough cleaning prior to application are essential to support durability outdoors.

In domestic garages, acrylic floor paints are suitable for foot traffic and light vehicular use such as cars and small vans, provided the concrete is sound and properly prepared. They are not intended for frequent heavy vehicle movement, pallet trucks or high point loading from axle stands. Tyre heat and turning movement may increase wear over time. Where higher mechanical resistance is required, a two pack epoxy or polyurethane system should be considered.

Acrylic floor paints offer limited resistance to incidental spills of oil or light automotive fluids if cleaned promptly. They are not designed for sustained chemical exposure or aggressive solvent contact. Prolonged contamination can soften or stain the film, particularly in higher temperature environments. In plant rooms or workshops where chemical exposure is frequent or heavy, a higher build epoxy or polyurethane system provides more appropriate chemical resistance and film durability.

Acrylic floor paints should be applied in dry conditions with substrate and air temperatures typically above 8–10°C and stable during curing. High humidity, low temperatures or poor ventilation can extend drying times and affect film integrity. The substrate must be dry and free from surface condensation. As a quick drying system, over-application should be avoided, as excessive film thickness can delay through-cure and reduce overall performance. Always follow specified coverage rates to maintain balance between build and durability.
