Spray applied polyurethane waterproofing membrane
ULFCAR® Polycoat CFM is a solvent free, two component, coloured waterproofing membrane. It is reactive and can only be applied by special, two component spray equipment.
- Fast reacting
- High build capability
- Application to vertical surface without runs
- Easy application to complicated details
- Fast installation
- Monolithic - no laps, welds or seams
- Fully bonded
- High water vapour permeability – low risk of blistering
- Excellent mechanical properties
- Excellent crack bridging capability
- Resistant to puncture
- Resistant to standing water
- Thermoset – does not soften at elevated temperatures
- Remains elastic at low temperatures-Tg approx. - 45°C
- Solvent free
Areas of application:
Ulfcar® Polycoat CFM is intended for use in general waterproofing applications such as car park decks, podium decks, cut and cover tunnelling, bridge decks under asphalt and concrete, and other areas where there is no requirement for a fire retardant system.
Using the appropriate primer, Ulfcar® Polycoat CFM can be applied to most substrates including concrete, galvanised steel, aluminium, UPVC, glass reinforced polyester etc.
Ulfcar® Polycoat CFM is normally applied at 1.6 – 2.1 kg/m2.
This corresponds to a thickness of approx. 1.5 – 2.0 mm.
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 re-coating 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.
Ulfcar® 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 Ulfcar® technical representative.
Ulfcar® Polycoat CFM should only be applied to properly prepared substrates.
Ulfcar® Polycoat CFM is available with the Part A coloured and the Part B unpigmented. This results in a uniform grey colour 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. Ulfcar® 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.
Ensure primer has cured to a ‘tack-free’ state prior to the application of Ulfcar® Polycoat CFM. Use the following guide to select the appropriate primer:
Top Coats and Wear Coats:
Ulfcar® 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 Ulfcar® representative office for details.
Note: if rain falls or dew occurs on the surface of Ulfcar® 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 Ulfcar® Polycoat CFM must be treated as above if left overnight.
