Armorgard 505
Form Coating

  • Extremely Tough Surface
  • BGE Free
  • Single Coat Application
  • VOC Free
  • Adhesion to Wood, Concrete and Steel
  • Bonds to Damp Forms
  • Armorgard 505 is a 100% solids, self-leveling, primerless, odorless epoxy form coating for precast, tilt-up, slip form or cast-in-place applications. Armorgard 505 is formulated to provide a hard, tough coating for wood and metal concrete forms. Use of Armorgard 505 transforms a “rough” form into a hard, smooth surface, creating an “architectural” quality cast.

    Armorgard 505 provides a convenient work life, rapid tack free time, and adhesion to damp surfaces. Armorgard 505 was designed from conception to be the ideal form coating.

    Armorgard 505 can be easily applied with a squeegee or roller. Normal application thickness is 15-30 mil (0.38-0.76 mm). Application varies depending on the porosity and roughness of the surface. A single build may be applied to horizontal surfaces up to 1/8" thick (125 mil or 0.3 cm). Armorgard 505 is conveniently packaged in 4 gallon, pre-measured kits, or bulk 5 gallon, 55 gallon and 275 gallon totes.

    Surface Preparation
    To achieve excellent adhesion, the substrate should be free of all loose and foreign material and should be clean.

    Oils, grease, waxes or other contaminates must be removed prior to coating. These can be removed with a solvent wipe using isopropyl alcohol or acetone or an application of warm (120-140 °F or 50-60 °C) caustic detergent followed by a hot water rinse. Repeat this procedure until the water does not "bead up" on the form. Armorgard 505 will not bond to a contaminated surface.

    Ambient Conditions
    Relative humidity and dew point must be determined before application to avoid adhesion failures. The dew point is used to predict the substrate temperature at which air begins to condense, in the form of water, on the substrate. Never apply a coating unless the form surface temperature is 5 °F (2.5 °C) above the dew point. This temperature difference must be observed until the epoxy coating is cured to a tack-free state. A dew point calculation chart is available from a Copps Technical Representative.

    Armorgard 505 will soften when exposed to extreme precast temperatures. A service temperature of no greater than 110 °F (43 °C) is recommended when removing forms coated with Armorgard 505.

    Mixing
    Mix 2 parts A (resin) to 1 part B (hardener) for 3 minutes using a Jiffy Mixer and a slow speed drill. Mix at slow speed (less than 850 rpm) to avoid air entrainment. DO NOT mix more material than can be used within the stated working time. REMEMBER - you will have less working time at higher temperatures.

    Application
    Armorgard 505 can be applied with a squeegee, brush, non-shedding roller or a grooved fiberglass roller. Re-coating a used form requires a light sanding to remove concrete residue and improve surface profile and adhesion.

    Clean-up
    Armorgard 505, before it is fully cured (hard), may be removed from tools with Copps Enviro Kleen solvent or warm soapy water.

    Safety Precautions
    Avoid breathing of vapors. Forced local exhaust is recommended to effectively minimize exposure. NIOSH approved, organic vapor respirators and forced exhaust are recommended in confined areas, or when conditions (such as heated polymer, sanding) may cause high vapor concentrations. Do not weld on, burn or torch Armorgard 505 or any epoxy material. Hazardous vapor is released when an epoxy is burned.

    Avoid skin or eye contact. Wash skin with soap and water if contact occurs. If eye contact occurs flush with water for 15 minutes and obtain medical attention.
    Read and understand all cautions on can labels and material safety data sheets before using this material.

    Armorgard K 315 Repair Kits

    Armorgard K-315 Repair Kits are a fast, easy and economical way to repair damage to an Armorgard coated deck. This material is a two-part epoxy that is designed to cure quickly so you won’t have any down time. It is available in a two part cartridge with a static nozzle as well as 2 gallon kits.

    How it works:

    The two part cartridge is fitted into a special gun (also available from Fister) and a screw-on static nozzle. Once fitted into the gun, with static nozzle attached, simply point over damaged area and press trigger. The material will cure in 15-20 minutes. The two gallon kits are mixed by hand at a ratio of 1:1. And applied by trowel or putty knife.
