AM257P Novolac Epoxy Primer Anti-Microbial

AM257P is a two component novolac epoxy primer with exceptional resistance to a variety of chemicals, solvents and acids designed for application as part of a protective coating system where splash and spills of acids, chemicals, and solvents occur.  AM257P offers high solids, good substrate penetration and low odor.

The AM257P Primer reduces air release generation from the substrate when applying higher solids novolac topcoats such as AM253 AM257P Novolac Epoxy Anti-Microbial Primer contains an antimicrobial chemical agent to prevent microorganisms from growing on the surface and are specially formulated to resist mildew growth on the coating film.   The dry coating film of these products are mildew resistant, resists mold fungus and resists stains by mold, In addition, the dry coating film inhibits the growth of bacterial odors, resists microbial odor development and  retards the growth and action of bacterial odors. As part of routine building maintenance, areas should be inspected for visible mold and the conditions causing the mold should be corrected to prevent mold from growing.

Recommended for priming concrete and cement substrates prior to applying other novolac topcoats.  This will result in fewer surface imperfections in high build and self leveling type coating.

Available in 3 gallon and 15 gallon kits and three colors: light gray, medium gray and tile red options.

PRIMER: None required

TOPCOAT: Many novolac products are suitable including our AM253 Novolac Anti-Microbial Epoxy

MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material room temperature before using.  Continuous storage should be between 60 and 90 degree F.  Low temperatures or great temperature fluctuations may cause product crystallization.

SURFACE PREPARATION: The most suitable surface preparation would be a fine brush blast (shot blast) to remove all laitance and provide a suitable profile. All dirt, foreign contaminants, oil and laitance must be removed to assure a trouble free bond to the substrate. A test should be made to determine that the concrete is dry; this can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

PRODUCT MIXING: Each 3 gallon kit of this product has a mix ratio of 2 gallons Part A to 1 gallon B by volume. Standard packages are in pre-measured kits and should be mixed as supplied in the kit.  Before the two components are mixed together, mix the part A and part B separately to insure they are uniform before they are combined.  After the two parts are combined, mix well with slow speed mixing equipment (recommend jiffy mixer) until the material is thoroughly mixed and streak free. This material has a high viscosity – mix well. 

Improper mixing may result in product failure. For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer. 5)

PRODUCT APPLICATION: The mixed material can be applied by brush or roller. Maintain temperatures and humidity within the recommended ranges during the application and curing process. Improper mixing or applying the product too thick can result in product failure.

RECOAT OR TOPCOATING:  This product is a primer, we recommend a topcoat. When you recoat or topcoat this product, you must first be sure that all of the solvents have evaporated from the coating during the curing process.  It is best to test the coating before recoating or topcoating. This can be done by pressing on the coating with your thumb to verify that no fingerprint impression is left. If no impression is created, then the recoat or topcoat can be started. Always remember that colder temperatures will require more cure time for the product before recoating or topcoating can commence. Before recoating or topcoating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film, or deglossing.) If a blush is present, it can be removed with any standard type detergent cleaner prior to topcoating or recoating. The primary choice of topcoat will be other novolac epoxy coatings. Multiple coats of this product are suitable prior to topcoating. 7)

CLEANUP: Use xylol.

FLOOR CLEANING: Caution!  Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique.  If no ill effects are noted, you can continue to clean with the product and process tested.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure).  It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

LIMITATIONS:  

  • Colors may be affected by high humidity, low temperatures or chemical exposure.
  • For best results use a 3/8” nap roller.
  • Substrate temperature must be 5°F above dew point.
  • All new concrete must be cured for at least 30 days prior to application.
