SKU: ProPOXY-CR-F-HARDENER Category:
ProPOXY CR F-Hardener is part of a chemical-resistant flooring system. Used in a 3:1 ratio with ProPOXY CR Resin, it delivers improved resistance to acids, solvents, and aggressive chemical environments. This fast-cure hardener supports quicker turnarounds without sacrificing performance under harsh conditions. Commonly used in laboratories, cleanrooms, and processing facilities, CR F-Hardener enhances the flooring system’s ability to withstand exposure to caustics and corrosive agents while delivering excellent durability and wear resistance.

DESCRIPTION

ProPoxy WB is a uniquely versatile, high solids, low odor, water-based floor and wall coating system. At a 3:1 mix ratio, its higher viscosity makes it ideal as a primer for porous concrete and block walls, or as a grout coat over decorative flake. Diluted in the field with 1 part, clean water (3:1:1) reduces its viscosity for deeper substrate penetration and better flow and leveling. ProPoxy WB is semi-permeable, tolerating high moisture vapor conditions as a breathable material.

FEATURES & BENEFITS

  •  Primer, Sealer, Base, & Grout Coatu  Water-Reducible for Lower Viscosity-u  Semi-Gloss Finish
  •  Up to 20+ Minutes Working Time, with Fast Dry & Recoat Time
  •  Clear Film @ 5-20 Mil Thickness
  •  Moisture Tolerant - Can be applied to  green concrete in as little as 2-3 days as a  concrete sealer
  •  Semi-Permeable - Allows moisture through the concrete coating without failure

STORAGE

Materials should be stored indoors between 60°F (16°C) and 90°F (32°C).

SHELF LIFE

One (1) year from date of manufacture.

LIMITATIONS

This product is best suited for application in temperatures between 50°F and 90°F. The presence of surface contaminants such as  oil, silicones, or other agents may cause  ProPoxy WB to fisheye or crawl. Surface contaminants should be removed with a suitable detergent and/or mechanical preparation prior to application.ProPoxy WB should not be applied greater than 20 mils (WFT). All divots, cracks, spalls, or voids should be pre-filled to ensure there is a hard cure of the material. ProPoxy WB will cure quicker in drier conditions when the relative humdity is below 50% at 70ºF, and there is some air movement in the application environment to facilitate evaporation rate. The coating will cure at a slower rate with higher humidity & lower temperature conditions, and with little or no air movement for evaporation. 

PRODUCT GUIDE

1. ProPoxy WB Resin is a water-based epoxy resin offering good viscosity for body and flow so it can be easily applied when combined at  1 part resin and 3 parts ProPoxy WB hardener. 2. ProPoxy WB Hardener is a water-based epoxy hardener balancing reasonable working time with a 3-4 hour cure (70°F, 50% RH) when combined with ProPoxy WB Resin.

COVERAGE RATE

If applied as a primer/sealer, a gallon of ProPoxy WB will vary in spread rate with surface irregularities and greater porosity in the concrete substrate. A minimum application of 5 mils (WFT) will cover approximately 320 s.f. per gallon. As a body or grout coat, do not exceed more than 20 mils (WFT) in a single application. 

PRELIMINARY FLOOR INSPECTIONS

CHECK THE CONCRETE: Concrete must be structurally sound, dry, and free of dust, laitance, curing compounds, paint, sealers, or other contaminants. If you suspect that the concrete has been previously sealed, call ProREZ technical support for further instructions.CHECK THE TEMPERATURE AND HUMIDITY: Floor temperature and materials should be between 55°F and 90°F. Excessive humidity above 75% will significantly reduce evaporation rates and overall cure of the material. With higher humidity, proper air movement is recommended. 

SURFACE PREPARATION

This product requires preparation in order to perform as expected. Substrate must be mechanically profiled (ASTM 4259-83), clean, sound, and dry. Removing any residual dust will help ensure a tenacious bond between ProPoxy WB and the substrate.

JOINT GUIDELINES

Depending on preference, joints may or may not be filled. If the joints are filled, non-moving joints, i.e. construction or control joints can be treated by using FlexPoxy with ProThickener FX.Note: Coating applied over filled joints may crack if there is concrete movement.

MIXING INSTRUCTIONS

Application Equipment:

  •  Personal Protective Equipment (PPE) & clothing per SDS (Safety Data Sheet)
  •  Jiffy® Mixer Blade (ES Model)
  •  Clean Mixing Container
  •  Low Speed /High Torque Power Drill
  •  Shed-Resistant Roller Cover- 3/8” Nap
  •  Application SqueegeeMix ratio for ProPoxy WB is 3 parts Hardener to 1 part Resin by volume. When combining, be sure to add the hardener into the clean mixing container first. Then add the resin scraping out the container. Always pour into the center of the mixing container. Add 1 part, clean, potable water to reduce viscosity, if desired. Mix the components thoroughly for 1-2 minutes with a Jiffler ES style mix blade. ProPoxy WB has an extended pot life of 1 hour at 70°F, 50% RH in 1 gallon volume mass.ProREZ Coatings, LLCP.O.

CARE

Proper maintenance will increase the service life and help maintain the appearance of your new ProREZ floor coating system. This product is considered to be a low maintenance coating system, however, certain textures and service environments require specific procedures. SEE “CLEANING GUIDELINES” for more information.

CAUTION

Avoid scratching or gouging the surface. All floor coatings will scratch if heavy or sharp objects are dragged across the surface.

Do not drop heavy or pointed items on the floor as this may cause chipping or concrete pop-outs in the case of a weak substrate cap.

Rubber tires can permanently stain the floor coating from plasticizer migration. In warehouse & industrial settings, the use of non-marking tires is highly recommended to prevent discoloration. Rubber burns from quick stops and starts can heat the coating to its softening temperature, causing permanent marking.

REPAIRS

Repair gouges or scratches or chip outs as soon as possible to prevent potential  chemical contamination.

DISPOSAL

Dispose in accordance with federal, state and local regulations.
