- Product Highlights
- CIM 500 is a tough, durable membrane specifically formulated to meet waterproofing demands in a buried and non-UV exposed application.
- It adheres to most materials to form a permanent, seamless barrier to water.
- It is well suited for plaza and podium decks, curbs, and areas containing multiple penetrations or irregular shapes, as well as split-slab applications.
- Available in both a vertical and horizontal grade.
Applications & Uses
- Markets
- Surface Preparation
General
- Substrates must be clean and surface dry with no oils, grease or loose debris.
- Perform adhesion tests to confirm adequacy of surface preparation.
Concrete
- Use of CIM epoxy primer is recommended to limit outgassing and maximize adhesion
- The substrate must be clean, surface dry and free of contaminates.
Steel
- SSPC-SP6 / NACE No. 3 Commercial Blast.
Other Metals
SSPC-SP1 solvent clean and abrasive blast to roughen and degloss the surface..
Wood- Substrate must be clean, dry and free of surface contamination.
- Use of CIM epoxy primer is recommended to limit outgassing and maximize adhesion.
Glass
Thoroughly clean. CIM VOC Compliant Bonding Agent must be used for proper adhesion.
Previous Coatings and Linings
CIM 500 may be applied over some existing coatings and linings. Perform adhesion tests to confirm adequacy of surface preparation. CIM VOC Compliant Bonding Agent can be used to achieve higher adhesion properties. C.I.M. Industries does not accept responsibility for determining the suitability of an existing coating or lining as a substrate for CIM products. Owner shall perform adhesion tests on any existing coating or lining to determine suitability.
Earth : Use CIM Scrim
UV Exposure
CIM 500 is not designed for long term UV exposure, exposure should be limited to no longer than 180 days.
- Temperature Conditions
Surface should be at least 50°F (10°C) and must be 5°F (3°C) above the dew point. Do not apply when the substrate or ambient temperature is rising or the applied coating is in direct sunlight. CIM 500 should be at least 50°F (10°C) when mixed and applied. CIM 500 may be preheated to facilitate application at low temperatures however working time will be reduced.
- Mixing
DO NOT THIN. DO NOT HAND MIX. Begin mixing each pail of CIM 500 Premix using a power mixer (e.g., 1/2” drill and an eight-inch mud mixer). Do not draw air into the mix. The premix and activator are packaged and supplied in the proper mix ratio. Failure to mix CIM 500 as provided will result in off-ratio or uncured coating. While mixing, slowly add one full jug of CIM 500 Activator to one full pail of CIM 500 Premix. Mix thoroughly for 3 full minutes. Mixing Jigs and Timers are available from C.I.M. Industries to help eliminate mixing errors and increase productivity on the job.
- Application
Apply CIM 500 directly to a clean and dry substrate. Vertical surfaces will require the use of CIM 500 Vertical Grade (VG) to achieve 60 wet mils in one application.
Equipment
Suitable for application with a roller, brush, squeegee, trowel, or spray equipment. Spray equipment requires large diameter hose and air supplied mastic gun. Airless pump may be used to provide fluid side pressure.
Working Time
Working time depends on temperature and method of application, typically 35-45 minutes. Working time for spray application requirements will be significantly shorter.
Priming
Porous substrates such as wood and concrete may be primed with CIM epoxy primer to minimize outgassing. CIM 500 must be applied within 48 hours of primer application.
Recoating
If multiple coats are needed to achieve 60 wet mils, CIM 500 should be recoated as soon as practical, typically within 2 hours from mixing. If the coating has cured longer than this, the
surface must be severely abraded using surface grinder or other mechanical means. The surface must be made free of dust and debris and then use CIM VOC Compliant Bonding Agent before applying the CIM 500.Recommended Minimum Thickness
The recommended minimum thickness of the coating is 60 wet mils.
Curing Time
Curing Time Typically, CIM 500 can be placed in service within 24-48 hours.
Clean-up
Use mineral spirits for clean-up of uncured material. Spray equipment must be flushed regularly during application to prevent material from setting up in the hose and pump. Cured material is very difficult to remove. Soaking in solvent will soften the material and may assist in its removal.

Safety & Health
- Precautions
Avoid contamination with water or moisture. Keep all pails and jugs tightly closed until ready for use. All equipment, air supplies, and application substrates must be ABSOLUTELY DRY. Do not apply in wet weather or when the CIM 500 or substrate may become wet within 6 hours after application. Use caution when applying CIM 500 in confined spaces
- Safety Information
Adequate health and safety precautions should be observed during storage, handling, application and curing.
