Rust-Oleum 5401 Epoxy Impregnation Primer

Rust-Oleum 5401 Epoxy Impregnation Primer – Deep Penetrating Primer for Porous Floors

Rust-Oleum 5401 Epoxy Impregnation Primer is a solvent-free, deep penetrating epoxy primer designed to strengthen and seal porous or brittle floors. Perfect for concrete and other mineral surfaces, it can be applied even on slightly damp substrates, making it highly versatile for real-world conditions. It's also an ideal base for concrete repair systems, ensuring optimal adhesion and durability.

Key Features:

• Deep Penetration – Reinforces porous and brittle substrates

• Solvent-Free Formula – Low odour and safe for interior use

• Can Be Applied to Damp Surfaces – No need to wait for complete drying

• Ideal Primer for Repairs – Perfect base for concrete repair products

• For Concrete & Mineral Surfaces – Versatile use across substrates

Application Details:

• Surface Types: Porous concrete and other mineral-based substrates

• Use Areas: Floors in industrial, commercial, and domestic environments

• Formulation: Solvent-free epoxy

Surface Preparation

New concrete should cure and dry for at least 30 days prior to the application of the
product. Remove oil, grease and all other surface contaminations by alkaline or high
pressure-(steam)cleaning in combination with appropriate detergents. Remove all laitance,
loose or unsound concrete by vacuum-blasting or etching with Surfa-Etch 108 Etching
Solution. Remove concrete curing compounds completely. Large surfaces should
preferably be prepared by abrasive blasting (vacuum blasting) or flame cleaning. Profile
maximum 0.5mm. Defects in the concrete should be repaired with 5180 Epoxy Repair
Mortar. Small (hair) cracks and air-pockets should be repaired with Epoxy Putty 5412. The
surface should be clean and dry during application.
