Penetrative Epoxy Primer FAQs

Penetrative Epoxy Primer is a two-pack, solvent-based epoxy primer for concrete surfaces. It is applied before a compatible floor coating to prepare the concrete and create a suitable base for the subsequent coating.

Its low-viscosity formulation penetrates deeply into the concrete, helping seal porous surfaces and re-strengthen weak substrates. It also contains an adhesion promoter to improve bonding between the concrete and subsequent PU or epoxy topcoat.

Penetrative Epoxy Primer is specifically formulated for concrete floor surfaces. It can be used for both interior and exterior flooring applications where a compatible coating system is specified.

The concrete must be properly prepared before application, with contaminants and unsound material removed and defects properly repaired.

Yes. Penetrative Epoxy Primer is designed to provide strong bonding between concrete and compatible PU or epoxy topcoats.

It can also be used as a tie coat between concrete and suitable solvent-based topcoats, helping the subsequent coating adhere more effectively to the prepared substrate

Yes. Penetrative Epoxy Primer is a two-pack epoxy product and requires the specified hardener for proper curing. The base and hardener must be mixed according to the recommended ratio before application. Once mixed, the product should be used within its specified pot life.

Concrete can be porous, which may affect how well a floor coating bonds to the substrate. Weak or poorly prepared concrete can also compromise the performance of the subsequent coating.

Penetrative Epoxy Primer is formulated to penetrate deeply into prepared concrete, seal its porosity and re-strengthen weak areas. Its adhesion promoter also improves bonding between the concrete and subsequent coating, helping create a more reliable base for the floor coating system.

Penetrative Epoxy Primer has a low-viscosity formulation designed for deep penetration into concrete. This allows the primer to penetrate into the substrate rather than simply remaining on the surface, helping re-strengthen weak concrete before a polymer overlay is applied.

However, cracks, hollow spots and other defects should still be properly repaired before applying the primer.

Penetrative Epoxy Primer is modified for deep penetration and enhanced with an adhesion promoter. This helps create strong bonding between the prepared concrete substrate, primer and subsequent coating.

Refer Technical Data Sheet

The concrete surface should be properly prepared and free from contaminants such as oil, fat, grease, existing paint residue, chemicals, and algae. . Cracks and hollow spots should also be properly repaired before application.

It is advisable to use acid using approximately 5% sulphuric acid solution, followed by thorough washing with clean water. The concrete should then be allowed to dry completely before applying Penetrative Epoxy Primer.

The substrate moisture should not exceed 4% by weight when measured electrically using a Tramex CME.

Refer Technical Data Sheet

The recommended application is one coat, with a theoretical coverage of approximately 7 m² per litre per coat at 50 microns dry film thickness.

Actual coverage can vary depending on factors such as surface roughness, application method, atmospheric conditions and applicator technique.

Refer Technical Data Sheet

Yes. Penetrative Epoxy Primer can be used as the primer layer within a suitable epoxy flooring or floor coating system. It prepares the concrete substrate by sealing its porosity, penetrating into the surface and improving adhesion before the subsequent coating is applied.

It is also suitable as a tie coat between concrete and solvent-based topcoats.

Refer Technical Data Sheet

Yes. Penetrative Epoxy Primer can be applied using either a brush or roller.

Because it is a two-component epoxy product, the base and hardener should be thoroughly mixed according to the specified ratio before appl

Penetrative Epoxy Primer does more than provide a layer between the concrete and topcoat. Its low-viscosity formulation penetrates deeply into the concrete, helping seal porous surfaces and re-strengthen weak substrates.

It is also enhanced with an adhesion promoter for excellent bonding, helping prepare the concrete for a durable subsequent floor coating.

Yes. Penetrative Epoxy Primer is specifically formulated to seal porous concrete and re-strengthen weak concrete substrates before polymer overlay.

Its low viscosity allows deeper penetration into the prepared substrate, while its adhesion promoter improves bonding with the subsequent coating.

Penetrative Epoxy Primer is formulated with a long open time, providing a suitable working period during application before the material cures.

Once the base and hardener are mixed, the product has a pot life of approximately 4 hours at 25°C, allowing applicators time to apply the mixed primer within the recommended working period.

Yes. Penetrative Epoxy Primer is suitable as a tie coat between concrete substrates and compatible solvent-based topcoats.

Nippon Paint specifically recommends it as the primer for concrete when using EA4 Finish, a two-component epoxy topcoat designed to resist abrasion and mechanical damage.

Penetrative Epoxy Primer can be used as the primer on properly prepared concrete floors before a compatible solvent-based epoxy topcoat, making it relevant to warehouse epoxy flooring systems where such a coating specification is suitable.

The primer itself is not the final wear layer. Its role is to penetrate and seal the concrete, re-strengthen weak substrate and improve adhesion before the selected topcoat or polymer overlay is applied.
