- Where to Use
Premier Rubber Membrane® is recognized as a Ballast Tank maintenance coating by Lloyds Register under Certificate No. MATS/3780/1. This premier material is also recommended for use on grade, above and below grade, interior and exterior applications. Premier Rubber Membrane® was designed to bond to most known substrates found in the construction, civil, water utilities, waste water, mining, agricultural, aquaculture, automotive, safety, industrial, military, protective and commercial/residential industries.
- Substrate Preparation
- Substrates must be free of all dirt, dust, grease, oil, sealers, curing compounds, form release agents, laitance and loose toppings.
- Only proceed with application when the temperatures remain between 40°F and 90°F (4°C and 32°C) and protect from freezing for 24 hours after application.
- All surfaces to be coated should be dry (damp is acceptable with no standing water). Hot surfaces should be cooled and shaded while cold surfaces should be heated and sheltered.
- For proper adhesion, concrete substrates must have a minimum CSP−3 Concrete Surface Profile as per ICRI Guideline No. 310.2-1997 (Formerly Guideline No. 03732).
- All loose particles and/or flaking coatings must be removed by sandblasting, water-blasting or other mechanical means.
- All detail work and tape application must be completed before application of membrane can be started.
Mixing:
For best results, mechanically mix for no less than 30 minutes for a 55 gallon drum and 45 minutes for a 275 gallon tote. Mix at slow speeds (not exceeding 500 rpm) to prevent air form entering the mix.- Application
Premier Rubber Membrane® is applied using a specifically designed piece of equipment that allows the material to atomize mid-air and start to catalyze before coming in contact with the substrate. The material must be mixed prior to and during its application to ensure proper disbursement of the elastomeric components added.
Curing:
Dries to the touch almost immediately and reaches a full cure within 72 hours at 70ºF with a relative humidity of 50%. While curing, water droplets will form on the membrane, this is the Calcium Chloride expelling the water that was used to carry it to the atomization of the two components.
Clean-up:
Promptly wash hands with baby oil. Clean tools and equipment with Mineral Spirits before material dries. Cured material must be removed mechanically.

Safety & Health
- Safety
Premier Rubber Membrane® contains zero V.O.C.s yet it is still that proper protective clothing, gloves and breathing filters are used when applying and handling this material.
First-aid:
Wash off with soap and water or use baby oil to remove from skin. If ingested consult a Physician. Never use gasoline for any clean up. For more information, consult Cantex Material Safety Data Sheet.
Note:
Proper application is the responsibility for the user. Field visits by Cantex personnel are for the purpose of making technical recommendations and not for supervising or providing quality control on-site.
