Product Use Instructions 

Surface Preparation

Concrete: Surfaces should be allowed to cure for a minimum of 20 days before coating. Excessive weak surface laitance must be removed by either acid etching or abrasive sweeping before coating. Aged, uncoated concrete surfaces are best prepared by abrasive sweeping. Contamination by oil or grease should be removed with an industrial degreaser before abrasive blasting or acid etching.

Steel: Most commonly used with fiber reinforced polymers (FRP) for structural reinforcement and sealing. When used with carbon fiber, it is recommended to apply an initial non-conductive seal coating or fiberglass layer to insulate the steel from possible cathodic effects. Prepare steel by abrasive blasting to SSPC-SP10, “Near White Blast” with a 2-4 mil anchor profile. Small areas may be prepared using mechanical tools such as needle scalers or abrasive discs.

Below Water: Remove marine biological settlement and corrosion by high pressure water jetting with or without abrasive. Conventional air/ abrasive blasting works well at shallow depths however efficiency falls off sharply below 10 feet. Hand held power tools such as needle guns or grinders can give good results in small areas. Apply within 45 minutes after surface preparation to minimize rusting or resettlement of biological fouling which interferes with adhesion.

Mixing Procedures.

This material is a two component product, premeasured to produce the desired kit size once part A and B are mixed. For small kits, a Jiffy type mixer with a high torque motor is recommended for proper blending. Pour the curing agent into the base and mix for about 1 minute, taking care to reach all corners and walls to eliminate unmixed material. Unmixed material will never harden. Material may immediately be used.

For larger areas, applications by heated plural spray should use the following equipment setup:

Mix ratio: 1/1 by volume

Fluid Pressure: 2,500 psi

Fluid Temp: 130-140F

Tip Size: .029″

Note: Pot life and reaction time is heavily depending on temperature. As a general guide, every 18F above 77F will half pot life and cure time.

Safety: This is a hazardous material if misused. Read and understand the Safety Data Sheets (SDS’s) before use
