- Inspection and Application
Application equipment:
- Use equipment/clothing as called for in Safety Data Sheet Jiffy® Mixer Blade model ES
- Clean container for mixing material
- Low speed high torque drill motor - 300 to 500 rpm
- High quality short nap roller covers1Τ4- 3Τ8” nap
- Application Squeegee
Substrate:
Mixing and Application must adhere to Material, Ambient and Substrate temperatures listed below or a decrease in product work- ability and slower cure rates will occur.
Temperature and Humidity:
Substrate Between 50°F min and 85°F max. (4°C min., 30°C max.) At least 5˚F (3˚C) above measured Dew Point
Ambient Air Temperature Minimum between 50°F (10°C) and 85°F (30°C)
Surface Temperature Minimum between 50°F (10°C) and 85°F (30°C)
Precondition Material At least 24 hours between 65° to 75°F (18° to 24°C)
Relative Humidity (RH) Limited to 30-75% (during application and curing)
Beware of condensation! Do not apply coatings unless the surface temperature is more than 5°F over dew point. This will reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.
Pot Life:
Material Temperature Time 50°F 40 minutes 68°F 30 minutes 86°F 20 minutes Preparation:
Surface must be clean, structurally sound, and dry. Remove contaminants, such as but not limited to, dust, laitance, grease, curing compounds, bond inhibiting impregnations, waxes. All projections, rough spots, etc. should be removed to achieve a level surface prior to the application. Concrete should be cleaned and prepared to achieve a laitance-free and contaminant-free, open textured surface by shot blasting or equivalent mechanical means (CSP-3 to CSP-4 as per ICRI guidelines). Sweep and vacuum any remaining dirt and dust with a wet/dry vacuum. Removing residual dust will help ensure a tenacious bond between the primer and substrate. Whenever “shot-blasting” is utilized, be careful to leave concrete with a uniform texture. “Over-blasting” will result in reduced coverage rates of the primer and/ or subsequent topcoats. The “shotblast” pattern may show through the last coat, known as “tracking”. The compressive strength of the concrete substrate should be at least 3,500 psi (24 MPa) at 28 days and at least 250 psi (1.7 MPa) in tension at the time of application. For other substrates, please contact Coating & Binding Technology’s Technical Services.
Mixing:
Do not hand mix Coating & Binding technology’s materials. Mechanically mix only. Do not thin this product. Addition of thinners (e.g. water, solvent, etc.) will slow cure and reduce ultimate properties of this product. Use of thinners will void any applicable Coating and Binding Technology warranty. Premix each Component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes using a low speed drill (300 - 500 rpm) and Jiffy style mixer suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.
Application:
Squeegee and back roll PC 4000 to provide a uniform coverage without ponding at a thickness of greater than 20 mils (80 ft2 /gal). If required, repeat this procedure for a second coat.
Recoat:
Before applying a second coat of PC 4000, wait a minimum of 90 minutes to a maximum of 24 hours with the ambient and substrate temperature at +68°F (20°C).
Curing:
Allow coating to cure for a minimum of 4 hours after application (for foot traffic only), 8 hours after application (for light traffic only), with the ambient and substrate temperature at +68°F (20°C) before use. Full coating properties may take up to 5 days to develop.
- Limitations
Measurement and confirmation is needed for the following components prior to application:
- Substrate Moisture Content
- Ambient Relative Humidity
- Ambient and Surface Temperature
- Dew Point
During installation, confirm and record above values at least once every 3 hours, or more often whenever conditions change (e.g. Ambient Temperature increase/decrease, RH rise/fall, etc.).

Disposal:
Dispose in accordance with federal, state, and local regulations.
Maintenance Guidlines:
Allow floor coating to cure at least one week before cleaning by mechanicalmeans(IE:sweeper,scrubber, disk buffer).
Care:
Increased life of the floor will be seen with proper maintenance and will help maintain a fresh appearance of your new CBT floor. Regularly sweep to avoid ground in dirt and grit which can quickly dull the finish, decreasing the life of the coating. Spills should be removed quickly as certain chemicals may stain and can permanently damage the finish. Only soft nylon brushes or white pads should be used on your new floor coating. Premature loss of gloss can be caused by hard abrasive bristle Polypropylene (Tynex®) brushes.
Caution:
Heavy objects dragged across the surface will scratch all floor coatings. Avoid gouging or scratching the surface. Pointed items or heavy items dropped on the floor may cause chipping or concrete pop out damage. Repair gouges, chip outs, and scratches as soon as possible to prevent moisture and chemical under cutting and permanent damage to the floor coating. Plasticizer migration from rubber tires can permanently stain the floor coating. If a rubber tire is planned to set on the floor for a long period of time, place a piece of acrylic sheet between the tire and the floor to prevent tire staining. Rubber burns from quick stops and starts from lift trucks can heat the coating to its softening point causing permanent damage and marking.
