Rustoleum 5412 - Epoxy Repair Putty is a solvent free, two component epoxy putty for repair of small cracks, air-pockets and/or blowholes in concrete walls, ceilings or floors.

Features:

• Extremely strong: 3x stronger than concrete
• Solvent-free and shrink-free
• Easy 1:1 mixing ratio Low odour
• For indoor and outdoor use

Recommended Use

5412 should be used for repair of small cracks, air-pockets and/or blow-holes in concrete walls and floors and is applied with a filling knife or a trowel. Can be applied directly on horizontal and vertical areas. Very porous substrates are to be primed with RUST-OLEUM 5401 Impregnation primer. Can be recoated with 9100, 5500, 9400, Pegakote etc.

Surface Preperation

Remove oil, grease and all other surface contaminations by alkaline or high pressure (steam) cleaning. Remove loose and unsound concrete until a sound surface is obtained. New concrete or masonry should dry and cure for at least 30 days before applying 5412 or a coating system. The surface should be clean and dry during application.

Directions For Use

Mix base and activator carefully with a filling knife, preferably not in the can but on a flat substrate alike a piece of hardboard..

Application  Conditions

Temperature of air and substrate between 10 and 35°C and relative humidity below85%. The substrate temperature must be at least 3°C above dewpoint.

Application & Thinning: Rake/Trowel

Apply a slight over-amount of the Epoxy Putty with a filling knife or trowel; after drying reshape the surface by abrading the excessive amount. Do not add any thinner to the product.

Theoretical Coverage

1.5 kg/m² per 1 mm thickness.

Practical Consumption

Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.
