SpECtop Primer F1

Two-part low viscosity epoxy resin floor primer.

SpECtop Primer F1 is a high-performance, two-part low viscosity epoxy resin designed specifically for priming concrete surfaces. It enhances the bond between the substrate and various epoxy floor toppings, ensuring optimal adhesion and durability.


This primer is essential for creating a strong foundation, allowing subsequent applications to achieve their full potential while maintaining the integrity of your flooring system.

Technical Details

SpECtop Primer F1 is versatile and suitable for various applications:

  • Excellent bond between cementitious surfaces and SpECtop epoxy resin floor toppings.
  • Primer for SpECbuild EM epoxy mortar.

Product FAQ

SpECtop Primer F1 can be used on concrete surfaces and cementitious substrates, providing an excellent bond for epoxy floor toppings and epoxy mortar applications.

To apply SpECtop Primer F1 effectively, first ensure the substrate is clean and free from grease, oil, and loose materials. Repair any damaged areas with SpECbuild repair mortars. Mix the two components until uniform, then use a stiff brush to apply the primer evenly on the prepared surface. Avoid over-application, and if absorption occurs, a second coat may be necessary once the initial coat is tack-free.

The coverage rate of SpECtop Primer F1 is 10 – 15 m²/litre.

Using SpECtop Primer F1 offers several benefits: it provides excellent adhesion between concrete surfaces and epoxy toppings, enhancing the overall durability of the flooring system. Its low viscosity allows for deep penetration into the substrate, ensuring a stronger bond that exceeds the cohesive strength of concrete. Additionally, it prepares the surface effectively, reducing the risk of delamination and extending the life of the applied flooring system.

The curing time for SpECtop Primer F1 varies depending on environmental conditions, but it typically requires several hours to become tack-free before applying subsequent layers.

When using SpECtop Primer F1, ensure adequate ventilation to avoid inhaling vapors. Avoid contact with skin and eyes; if contact occurs, rinse thoroughly with water and seek medical attention if necessary. Use protective gear such as gloves and goggles. Keep away from flames and sources of ignition, as the product is flammable. Store in a cool, dry environment and follow all applicable safety guidelines when handling.
