Application Specification


PRODUCT NAME
DC333 Fireproof Paint, Paint To Protect ™
MANUFACTURER
International Fireproof Technology, Inc.
 
Surface Preparation: All surfaces to be painted must be clean, cured, firm, dry and free of dust, dirt, oil, wax, grease, mildew, efflorescence, loose flaking paint, etc. Glossy surfaces should be dulled by sanding.  Patch nail holes, cracks, blemishes etc., with appropriate patching compounds and sand smooth.   For best results rough, irregular surfaces should be sand feathered.  Remember, the quality of any paint job is only as good as the surface preparation that precedes the paint application. While our product has excellent bonding characteristics, even the best coatings will fail to bond over time, if sub-surfaces are inadequately prepared.
  • Priming:
    • New Work: While DC333 may be used as the primer on many surfaces such as wood and sheetrock, for best results it is recommended that all new work is primed with standard primers designed for each surface and our coating be applied as an intermediate coat before top coating. Ask your paint dealer for recommendations of appropriate primers for each substrate.
    • Repaint Work: Our coating has excellent bonding characteristics and will adhere to most sound, clean, matte surfaces. If the surfaces are suitable for ordinary house or wall paints to adhere to, then they are suitable for our coating.  Hard glossy surfaces should always be sanded for best adhesion.  If the previous paint was an oil-based coating, always sand and prime with a suitable oil-based primer, or specialty acrylic bonding primer, before proceeding with our coating. Your local paint dealer can recommend an appropriate primer.  If in doubt, feel free to contact our office for further assistance.
    • Mildew: should be removed by scrubbing with a 25% solution of household bleach water. Tri-sodium phosphate (TSP), or common laundry powder such as Tide™ may be added to solution to assist removal. Always rinse with clear water.
    • Efflorescence: is a white powdery alkaline crystal growth sometimes found on plaster or masonry walls. It is a condition caused by excessive moisture in the walls forcing alkaline salts to the surface of the wall. Efflorescence must be removed and neutralized with an acidic solution (white vinegar works well). 
    • Caution: the presence of efflorescence indicates that a moisture problem has occurred behind the wall at some point in time.  If the source of excessive moisture is not corrected, the efflorescence will return and push any coating, including ours, off the wall. 
  • Material Preparation:
    • DC333 Fireproof Paint must be thoroughly mixed before application. Failure to do so will seriously compromise our coating’s ability to perform. We recommend mechanical stirring with a high speed drill and a paddle appropriate for the size container you are working from. Contents should be stirred from the bottom up, making sure to scrape the bottom and sides with a paint stick as you go. Contents should be stirred to a creamy consistency with no lumps. Thinning is usually not needed or recommended. 
    • DC333 is a water based product and slight thinning will not hurt the product, however, thinning increases the likelihood of not applying the proper thickness of paint thus diminishing our product’s fire proofing ability. Ultimately, it is your responsibility to make sure that the proper thickness of material has been applied so our product can do its job. Except for tinting with universal paint tint, never mix our product with other materials. Helpful suggestion (When applying two coats of DC333 slight tinting of first or second coat will assist in making sure all surfaces are recoated.)
Wood, Gypsum Board and Foam (see individual test reports for various thickness)
  • UL-723 - Class A Flame Spread & Smoke Production.
  • ASTM E 84 – Class A Flame Spread & Smoke Production.
  • UBC-26-2 - Thermal Barrier.
  • NFPA-286 - Contribution to Room Combustibility.
  • ASTM E 119 - the standard time-temperature curve based on post flashover conditions. The test measures the ability of wall and partition systems, floor ceiling and roof ceiling systems to stop flame or hot gases, penetrating thru the assembly.
Application Equipment: DC333 can be applied by brush, roller or airless sprayer.
Brushing: Use top quality polyester/nylon blend brushes such as those supplied by Purdy™, Wooster™, or equivalent.
Rolling: 3/8” polyester blend nap roller covers generally work well when applying DC333 by roller.
Spraying:
  • Pump:  For best results use a piston pump airless sprayer with a minimum 1GPM rating at 3000psi.
  • Tip: 517 – 521, or equivalent.
  • Filter: 60 mesh
  • Hose: Use minimum size of 3/8” airless spray line for the first 50’ from pump.
  • Use of a dedicated spray line is required.  

Airless Spray:

  • Fluid Pressure:.........................2100 PSI or higher
  • Strainer:....................................60 Mesh
  • Fluid Hose: .............................3/8" diameter with a ” whip
  • Tip: ..........................................017 - .021 

Recommended thickness depends on the substrate and the level of protection needed. See test data for recommendations, or call the manufacturer for technical assistance.

Application Temperatures:

Temperature of substrate and application must be 50 F and rising. 68 to 90 F are recommended temperatures for applying. Do apply if temperature will fall below 50 within two hours of application. It is the sole responsibility of the applicator to ensure that DC333 has been applied in accordance with the application directions. Application should not proceed if surface or air temperatures exceed 90 F.

Workmanship: 

General:
Apply DC333 fireproof paint according to manufacturers written instructions.  Use applicators and techniques best suited for substrate and type of material being applied.
Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to forming a durable paint film.
Paint surfaces behind movable equipment and furniture the same as similar exposed surfaces.
 
Coverage:
Apply at a rate of approximately 8 wet mils @ 200 square feet per gallon application. Dry film thickness (DFT) will be approximately 5.38 mils. The final (DFT) will vary and depends on the substrate of the specific assembles.
 
Cleanup:
At the end of each workday, remove rubbish, empty cans, rags, and other discarded materials from Project site.
After completing painting, clean glass and paint-spattered surfaces. 
Remove spattered paint by proper methods. Be careful not to scratch or otherwise damage adjacent finished surfaces.
Provide "Wet Paint" signs to protect newly painted finishes.
After completing painting, remove temporary protective wrappings provided by others to protect their work.

Health & Safety

All work carried out under this specification shall be in tradesman-like manner, with due regard to prevention of contamination of the site and associated work.
Appropriate steps are to be taken to protect the health and safety of any person who has reason to be on the site.
Refer to the governing Health and Safety regulations and minimise the hazards on site by using the proper trade approved equipment and techniques. Ensure supply and appropriate use of protective clothing and equipment.

Lead: Existing coatings may contain lead. Test surfaces accordingly. All necessary precautions must be taken with existing painted surfaces that contain lead.

Asbestos: Contractors need to comply with local regulations and guidelines before commencing any work on surfaces and substrates that may contain asbestos.

Quick Check

Prior to starting DC333 application:

Check
 
check1 Temperature – Is temperature within limits (68 to 90 F)
check1 Humidity – Is the relative humidity less than 85%?
check1 Consistency – Are the contents thoroughly mixed?
check1 Surface – Are all substrates clean, dry and sound?
check1 Measurement – Wet film gauge on site?
check1 Safety – Are Health and Safety checks complete?
check1 Need help – Call 949.724.5056
 
Wet Mil and Dry Mil:
During Application, the wet film thickness should be checked using a wet film thickness gauge. To use the gauge insert the teeth into the wet DC333 wet base coat, the last tooth to be coated indicates the thickness achieved. This is very important so you can achieve the required dry film thickness (DFT) of the specific assembly.
During the drying process, DC333 will shrink due to evaporation.

Loss Factor
For actual coverage rates, allowances must be made for such factors as surface irregularities, anchor pattern, film thickness, variance, loss, overspray, and incomplete usage.
The following factors have been found in actual use to be reasonable estimates of the loss factors which can be expected:
  • Brush Application .............3-5%
  • Roller Application .............3-6%
  • Spray Application .............8-10%
