Applications & Uses
- Markets
- Compatible Substrates & Surfaces
- Intended Uses
- Primer for horizontal and vertical concrete surfaces.
- Increases bond of coating system over surfaces that may be contaminated with oils.
- Limitations
- This product may not cure properly in temperatures below 50 F (10 C) All epoxies will show chalking/yellowing on exterior exposures.
- Application of epoxy coatings in cool temperatures and high humidity can result in the formation of amine blush. Blush may appear as a milky, white, tacky residue on the surface of the cured coating and must be removed before the application of another coat.
- Intercoat adhesion problems may occur if blush is not removed.
- Surface Preparation & Application
Surface Preparation
New Concrete – Concrete must be properly cured for a minimum of 28 days before application of coating. Surface must be entirely free of oil, grease, dirt, detergent, surface water, laitance, curing compounds, coatings or other contaminants that may interfere with adhesion. The concrete must be abrasive blasted to provide an anchor pattern (similar to 60-80 grit sandpaper min.) for adhesion. Final prepared surface should be clean and rough. Consult SSPC-SP13 – Surface Preparation of Concrete. Old Concrete - Surface must be entirely free of oil, grease, dirt, detergent, surface water, laitance, curing compounds, coatings or other contaminants that may interfere with adhesion. The concrete must be abrasive blasted to provide an anchor pattern (similar to 60-80 grit sandpaper min.) for adhesion. Final prepared surface should be clean and rough. Consult SSPC-SP13 – Surface Preparation of Concrete. Do not use NSP 100 as a primer over tightly adhered old coatings.
Mixing Instructions
This is a two-component system. Complete unit must be mixed and applied at one time. Do not mix partial quantities from containers or proper component ratios may not be obtained. Prior to mixing, components a resin and b hardener should be at room temperature (60-75 f/16-24c). Pour part b hardener into part a resin. Mix for 3 minutes using a jiffy mixer head and a mechanical drill. To ensure complete mixing, scrape sides and bottom of container and continue mixing for an additional minute. Do not hand mix. Begin application immediately – no induction time.
Mixed Ratio - 5 Parts A (Resin)1 Part B (Hardener) by volume Do not partial mix.Application
Air and surface temperature should be between 50-90F/10-32C. Do not begin application if air, substrate or material temperature is below 50 F/10C or expected to fall below 50F/10C within 12 hours of application. Do not begin application if dew point is within 5F/3C of the temperature. Variations in temperature can affect pot life of this material. Clean up using Acetone or other Ketone Solvent.
Method of Application: Brush, Phenolic Core Roller, Airless Spray
