Applications & Uses
- Applications
- Coating Type
- Typical Areas of Installation
Polycoat CFM is intended for use in general waterproofing applications such as car park decks, podium decks, cut and cover tunneling, bridge decks under asphalt and concrete, and other areas where there is no requirement for a fire retardant system. Using the appropriate primer, Polycoat CFM can be applied to most substrates including concrete, galvanized steel, aluminum, UPVC, glass reinforced polyester etc.
- Substrate Preparation
The substrates to be coated have to be firm, dry and loadbearing, free of loose and brittle particles as well as substances which impair adhesion such as oil, grease, rubber skid marks, paint or other contaminants. Pretreatment of the substrate by grit or shot blasting, highpressure water jetting, grinding or scarifying is only necessary when the primer or scratch primer is very dirty or, when the recoating interval has been exceeded. After pre-treatment of the substrate the bond strength of the substrate must be at least 1.5 MPa. The temperature of the substrate must be at least 3°C above the current dew point temperature. The substrate to be coated must be protected against rising damp (back pressure), if required. Polycoat CFM can only be applied by means of a suitable two component spray machine. The choice of machine depends to a large extent on the type and size of work contemplated. For advice, please contact your local Nivapol technical representative. Polycoat CFM should only be applied to properly prepared substrates. Polycoat CFM is available with the Part A colored and the Part B unpigmented. This results in a uniform gray color of the sprayed material thus giving the sprayer a visual control of the quality of the mixing as machine faults become immediately obvious. This can reduce costly clean up time and material wastage. Due to the fast reaction it is possible to rapidly build thicknesses from 1.0 to > 6 mm. Surrounding areas should be protected from overspray by masking off with e.g. polyethylene sheet. or paper. Care should be taken to prevent spray mist being carried by wind by erecting suitable barriers. Polycoat CFM should be applied within the recommended temperature and relative humidity limits. The temperature of the substrate should be min. 3ºC above the dew point.
- Primer
Ensure primer has cured to a ‘tack-free’ state prior to the application of Polycoat CFM. Use the following guide to select the appropriate primer:
Substrate :Concrete
Primer: Standard EP Primer
Substrate: Other substrates
Primer:Contact your local Nivapol technical representative- Top Coats and Wear Coats
Polycoat CFM does not have sufficient UV and weather resistance to be used in permently exposed applications without protection. A number of top coats and wear coats are available which can be broadcast with dry silica sand to provide a hard wearing, non-slip surface Other top coats may be more suitable for specific applications, contact your local Nivapol representative office for details. Note: if rain falls or dew occurs on the surface of Polycoat CFM then the membrane must be dried and the primer applied prior to the application of any wear coat or top coat (even if the re-coat interval has not been exceeded). In the tropics any exposed Polycoat CFM must be treated as above if left overnight.
- Post Application Quality Control
1. Adhesion test
2. Thickness control test
3. Visual test for pinholes and blisters

Safety & Health
- Warnings and Precautions
Wear safety gloves, goggles and protective clothing. Avoid contact with the skin and eyes. In case of eye contact, seek medical attention. Avoid inhalation of the fumes. Respiratory protection must be worn when spraying or when in the vicinity of the spraying operation. When working well ventilated areas combined charcoal filter and particle filter masks (A-P2) should be worn. When working in less well ventilated and in confined spaces, air-fed helmets are to be worn by sprayer and assistant(s). When working with the product do not eat, smoke or work near a naked flame. The regulations of the local trade association and/or other authorities, regulating safety and hygiene of workers handling polyurethane and isocyanates must be followed. For the full health and safety hazard information and how to safely handle and use this product, please make sure that you obtain a copy of the Material Safety Data Sheet (MSDS) from our office or our website
