- Suggested Uses
Use primarily as a base coat, final, or intermediate clear sealer.
- Limitations
Contamination and surface defects: If contaminates including oil, silicone, mold release agents and/or other materials are present, resin systems may fish-eye or crawl away from the surface. All surface contaminates should be removed with a suitable detergent prior to application. Solvent cleaning of silicone based contaminates is NOT RECOMMENDED. Please contact Technical Service for additional recommendations. DC 1200 may amber slightly over time from UV exposure. CBT can recommend a UV protective coating that can enhance UV stability.
- Inspection and Application
Substrate:
The substrate must be free of curing membranes, silicate surface hardener, paint, or sealer and be structurally sound. If you suspect concrete has been treated or sealed, proceed with complete removal process. Consult your CBT representative for further instruction if silicate hardeners or membranes have been utilized.
Moisture:
Moisture and moisture vapor transmission rates are dynamic in nature and may change over time. Initial testing does not guarantee future results. If the relative humidity of the concrete substrate is over 75% (using ASTM F2170), CBT must be consulted and issue a written moisture mitigation recommendation prior to product use.
Vapor/ Contamination:
Testing for MVT does not guarantee against future problems. If there is no known vapor barrier or it is inadequate, there is a risk of bond failure. Other factors including the migration of oils, chemicals, excessive salts or Alkali Silica Reaction (ASR) from the concrete may also elevate the risk of adhesion difficulties.
Temperature and Humidity:
During application and cure of coating, substrate temperature, material temperature, and room conditions must be maintained between 65°F (18° C) and 90°F (32°C). Relative Humidity (RH) should be limited to 30-80%. DO NOT apply coatings unless the surface temperature is more than five degree over dew point.
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
- High quality short nap roller covers- Τ 1 4 - Τ 3 8 " nap
- Application Squeegee
- Graco M2K Plural component Pump for spray applications
Preparation:
Surface dirt, grease, oil and contaminates must be removed by detergent, scrubbing and rinsing with clean (clear) water.
Joints:
All non-moving joints (control joints) can be filled with a rigid or semirigid joint compound. Construction joints may be filled with semirigid joint filler and might need to be re-built and re-cut depending on conditions. Isolation or expansion joints must be filled with a flexible material designed for expansion and should not be coated over.
Mixing:
In bulk packaging containers such as 5-gallon and drums, pre-mix the Part A prior to in field metering. Mix ratio is 3 Part A to 2 Part B by volume. Mix both components together for 2-3 minutes with a Jiffy® ES mix blade attached to a slow speed drill. Mix only enough material at one time that can be applied without exceeding pot life. Once mixed, it can not be resealed for later use.
Application:
Apply to floor surface using a notched or flat squeegee depending on desired thickness. Material sitting in pail longer than five minutes will result in increased viscosity and reduce leveling properties. Back roll and spread evenly to wet coating using a 1Τ4 - Τ 3 16” inch nap nonshed roller. Care should be taken to not over roll the coating introducing air to the surface. For spray applications, a Graco M2K Plural Component Pump can be used to spray desired mil thickness.
Recoat:
Only topcoat with CBT urethanes or epoxies, and within 24 hours at 70- 75F 30% RH. If the re-coat window has expired, the prior cured coating surface must be sanded with 100 grit sandpaper or sanding screen installed on a swing-type floor buffer. Sand to a uniform dulled surface. Remove all sanding debris with a vacuum and damp mop. Surface must be dry before coating.
Curing:
Allow coating to cure for a minimum of 24 hours after application, at 75°F (24°C) and 50% RH before use (light traffic only), allow more time for low temperatures and higher humidity or for heavier traffic. Full coating properties may take up to 7 days to develop.

Disposal:
Dispose in accordance with federal, state, and local regulations. Read safety data sheet for safety and precautions. Use product as directed for industrial use only. Keep out of reach of children.
Maintenance Guidlines:
Allow floor coating to cure at least one week before cleaning by mechanical means (IE: sweeper, scrubber, disk buffer). 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 Poly- propylene (Tynex®) brushes.
Cautions:
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 pre- vent 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.
