Storage: Store all product in a clean, warm area where the temperature remains between 50-110ºF (10-43ºC). Cold products are very viscous and will be difficult to mix and apply. Products shipped during cold months can remain cold for many days even when stored as recommended. Paste or trowel applied products will remain cold longer than liquid or spray applied products. Heating of the individual components may be required to bring the products to the recommended temperatures.
Surface Preparation: SSPC-SP 13
All surfaces to be lined are to be clean, dry, and oil free. Refer to the DUROMAR Information and Application Guide for specific instructions for various surfaces such as concrete, metal fiberglass, etc.
- Minimum surface temperature during application - refer to Product Data Sheet.
- For Brush, Roller, or Spray Applied Products, the surface profile must be 3 mils minimum.
- For Trowel Applied Products, the surface profile must be 4 mils minimum.
Application Equipment:
- Brushes - short bristle, nylon, and non-shedding. Replace when products become hot or stiff.
- Rollers - short nap (3/8” max.) nonshedding, with a polyethylene core. Replace when products become hot or stiff.
- Airless Spray Equipment – Single, Plural recommendations are listed in the DUROMAR Information and Application Guide.
Mixing:
- Do not add solvent to any DUROMAR product. These 100% solids materials are formulated to be applied as shipped after proper mixing.
- The temperature of the Hardener (A) and Base (B) portions should be between 70-80ºF (20-25ºC). Mix them separately to insure a uniform consistency.
- Add the entire contents of the Hardener (A) to the Base (B) bucket. Use a brush or squeegee to assist in the transfer. These portions are accurately measured and best product performance will be obtained if all the Hardener and Base is combined. Pouring from one container to the other (boxing) during mixing is very helpful in insuring complete mixing.
- Mix the products until no streaking is observed and then for about one (1) minute longer.
Application:
- For hand application, immediately break down the full unit into smaller portions such as roller pans, small buckets, or trowel boards. This will keep the product cooler and improve the useable life.
- For spray application using a single or plural component airless system, see Section 4 in the DUROMAR Information and Application Guide. Make sure all components are working according to the airless equipment manufacturers’ instructions and the product components are at the recommended temperature before spraying.
Overcoating: When applying multiple coats of any epoxy products, always check for Amine Blush before applying the next coat. Amine Blush may occur when the epoxy surface is cool or in humid environments. It has the appearance and feel of a light oil film on the surface. When dry it has a white chalky appearance. If detected, wash the surface with a 2% hydrochloric acid solution followed by a water wash until the surface pH is between 6-8. Allow to dry before applying the next coat.
Clean Up: Most solvents and commonly used thinners such as MEK, acetone, xylene, I,I,I trichloroethane, and safety solvents such as Ensolv, etc., can be used for cleaning tools and equipment. However, as many of these materials are flammable or present other safety hazards, the user should read the MSDS for these materials before using. In no event should these materials be used to clean material from the skin, eyes or clothing.
