No, DC315 is an alternative compliance product that is accepted under code provision 188.8.131.52.(1) of the NBC of Canada. Performance based testing completed by NRC and CCMC issued Report #14036-R conclude DC315 provides equivalent protection to that of ½” gypsum board or any Class B product tested to the CAN/ULC S124.
CCMC report #14036-R states DC315 serves as a thermal barrier over MD spray urethane foam insulation in Part 9 Buildings and that other applications are permitted where thermal barrier protection of medium density spray urethane is required as per NBC 2010/2015 and a similar level of protection is specified (i.e. 12.7mm gypsum board) and would be subject to approval by the authority having jurisdiction.
Always refer to the design listing or test report for the applicable thickness required for the Province you are applying DC315.
The application rate depends on the Province of end use. Testing results show that 3 mils of primer and 20 mils of DC315 will surpass generic barriers. An application rate of 3 mils of primer and 24 mils of DC315 will provide equivalent protection to ½” gypsum.
All applications in Canada require the use of a primer. Currently the only tested primer is DTM Bonding primer, available at Sherwin Williams.
National Building Code of Canada section 184.108.40.206 requires protection from mechanical damage. CCMC Report #14036-Rdocuments testing to ensure the long term durability and resistance to impact of the coating. Using a primer, DC315 has surpassed impact and durability testing of ½” gypsum board and provides and long term safe solution for protecting SPF.
DC315 can be tinted with up to 1 oz per gallon of standard tints. When deeper tones are required it is recommended to apply a top coat of alkyd interior paint that has been tinted to the desired color and finish.
DC315 does not require thinning. Normally 5 minutes of mixing is all that is required to return DC315 to its factory viscosity, however older material may have some evaporation in which case water (How much) can be added to bring the bucket up to the fill line, 3” below the top of pail. Ensure the product is mixed well for at least 5 minutes following the addition of water to ensure a consistent product.
When is a top coat required? – Alkyd interior top coats can be used when the desired color and/or finish is required. Tested top coats will not affect the intumescent properties of DC315. When DC315 is exposed to high humidity environments it is required to install a vapour barrier top coat over DC315. Always allow DC315 to cure a minimum of 4 hours prior to installing a top coat. Contact IFTI for a complete list of tested top coats to meet your application.
1 year in unopened containers
3000 psi and 1 gallon per minute with a 517 -523 tip size. (Graco 795 and higher). Removal of screens from machine and gun is required.
DC315 is designed for thermosetting (non-melting) type plastics like spray polyurethane foam and is not designed for substrates other than spray polyurethane foam.
No, DC315 is tested as a thermal barrier only. Confused
DC315 is an interior water-based acrylic and will freeze at temperatures below 0°C. Recommended installation temperature of a minimum of 10°CFull temperature range must be maintained for the duration of Install and curing. It is also important to monitor humidity and do not install DC315 when humidity is over 85% or temperature is within 3°C of the dewpoint.
Cold storage applications require specific application products and techniques. It is imperative that the installer contact IFTI for specific instructions.
