Frequently Asked Questions

Q1: How do you mix CIM materials?

CIM coatings have two components: CIM Premix and CIM Activator. Each container has a color-coded label in order to assist with identifying the appropriate combination of CIM Premix and CIM Activator. One-gallon cans should be mixed with a 3” spiral blade. Five-gallon pails must be mixed with an 8” mud mixer. All CIM products are to be mixed for three (3) minutes by mechanical means before being applied. IG-8: Instruction Guide Mixing CIM Premix and Activator has more detailed information regarding mixing CIM.

Q2: Can I break-down a unit of the CIM Premix and CIM Activator?

Each CIM Premix and CIM Activator is pre-measured. It is critical that the appropriate amount of CIM activator be mixed with the appropriate amount of CIM Premix. Therefore, CIM does not recommend breaking down units of the material. CIM 1000TG and CIM 1061 come in one (1) gallon units for smaller projects and we also sell the CIM 1000TG as a dual cartridge.

Q3: What are the package sizes for CIM products?
  • 4 1/2-Gallon Units: CIM 800, CIM 1000 and CIM 1061
  • 5-Gallon Pails: CIM 1000TG
  • .8-Gallon kits: CIM 1000TG and CIM 1061
  • 850ml Dual Cartridge: CIM 1000TG

For larger jobs the CIM material can be sold as drums or totes. Please contact us for more information.

Q4: Do your coatings come in different colors?

CIM products are available in black (CIM 800, CIM 1000, CIM 1000TG and CIM 1061).
The CIM system can be top-coated to change the color by using colored aggregates and epoxies in immersion applications and color urethanes and acrylics in non-immersion applications. Please review the CIM Instruction Guide IG-7 TOPCOATS for additional information.

Q5: Can CIM products be applied to wet or green concrete?

CIM products should be applied to dry concrete with less than 5% moisture. We recommend that two different types of moisture tests be conducted to ensure the concrete is dry before applying our coating. Please refer to the CIM Instruction Guide IG-2 Application of CIM to Concrete under section 4.4 Testing for Moisture has additional information regarding the test methods. CIM EMT Primer can be used over green concrete or concrete that does not meet CIM’s standard moisture content requirements.
If you have additional questions please contact Chase Corporation.

Q6: Are CIM products suitable for shower pan linings?

CIM products are excellent for use in shower pans. CIM products adhere tenaciously to substrates commonly found in shower pans including, stainless steel, galvanized steel, concrete, fiberglass, PVC, cast iron, wood, copper, and previously coated surfaces. Unlike other coating systems CIM materials are cold applied and can be easily installed, It cures in as little as 4-hours. It does not require dangerous hot kettles or the need to transfer hot materials to a location for use. CIM materials are also VOC compliant and have very low odor.

CIM can also be applied with a tack-coat and broadcast of sand to accept mortar beds and thin set for tile applications

Advantages of CIM Products: All CIM products are UPC and Building Code Approved as a shower pan liner, Low Odor, VOC Compliant, Cold Applied, Easy to Apply, Stops Leaks, Chemical Resistant, Elastomeric, Cures Quickly, Impermeable, Abrasion Resistant, Easy to Clean, Easy to Repair, Expands Life Expectancy

Q7: Can CIM products be used in green roof applications?

CIM is an excellent waterproofing coating with the toughness and flexibility to extend the life of an existing roof or new construction for many years. CIM has been tested as a root barrier and passed the FLL Test for green roof membrane.

Q8: Can CIM products help you attain LEED points on a job?

CIM industrial coatings can help gain LEED Points in the following sections:

Sustainable Sites

  • SS Credit 6.2: Storm water Design – Quality Control (1 point)– The CIM polyurethane coating can be used to help implement a plan to infiltrate and capture storm water.
  • SS Credit 7.1: Heat Island Effect – Nonroof (1 point) – The CIM polyurethane coating can be used to waterproof green roof applications.
  • SS Credit 7.2: Heat Island Effect Roof (1point) – The CIM polyurethane coating can be used to waterproof green roof applications.

Water Efficiency

  • WE Credit 2: Innovative Wastewater Technologies (2 points) – The CIM industrial coating can be used to capture rainwater and recycled gray water.
Q9: Are CIM products suitable for exposure to H2S gas (hydrogen sulfide)?

CIM products have excellent chemical resistance to H2S gas. The CIM 1000 Chemical Resistance Chart has a list of other chemicals that CIM materials resist. Please contact Chase Corporation if you have a chemical question that is not listed on the chart.

Q10: Which product should be used for a cooling tower basin?

CIM 1000, CIM 1000TG and CIM 1061 are all appropriate to coat and protect cooling tower basins. Unlike other coating systems for cooling towers, CIM products can be applied in a single application and may be placed into service within 24 hours. CIM products are not affected by water treatment chemicals and will not affect water chemistry. CIM materials adhere tenaciously to substrates commonly found in cooling towers including stainless steel, galvanized steel, concrete, fiberglass, and previously coated surfaces.

Q11: Are CIM materials approved for potable water contact? Where can I find the approval?

CIM material is approved for potable water for tanks of 5,000 gallons and greater. CIM 1061 has the NSF/ANSI 61 Potable Water approval through Underwriters Laboratories and Water Quality Association.

Q12: Do CIM materials come in rolls?

CIM materials are liquids and do not come in preformed rolls. CIM products can be applied using conventional methods (brush, roller, and squeegee) and cures to form a rubber-like lining. Because it is a liquid applied coating, it will easily conform to irregular shapes and around complex penetrations. CIM products, unlike sheet goods, will not permanently deform, rather they are tolerant to greater stress and require less initial site preparation. CIM material leaves no seams, thus leaving no potential for seam failure.

Q13: How can I buy CIM products?

CIM materials can be purchased through stocking distributors. To find the distributor nearest you please contact Chase Corporation.
