You hear (read) my stories and how I discuss the importance of fire resistant deck coatings being used in the construction of homes, offices and hotels/motels etc. We are often asked to compare our product to competitors products, what the differences are, costs, warranties etc.
While those are important to discuss, even more important is building and life safety. Stairs and walkways on second floors are means of escape for occupants to escape from in the event of a fire. Rood decks and balcony decks must be fire resistant too.
ICC-ES, the leading authority in building materials and construction, has developed many standards to be able to objectively and scientifically test building components for their intended use. Walking decks is one component that has specific acceptance criteria (AC-39 Click to read it) that manufacturer’s products MUST meet to be “approved” as a walking deck system.
Our Desert Crete decking system has one. Read it here – ICC-ESR-1661 . The report proves what the manufacturer claims-it’s fire resistant as per ASTM E-108 and it’s rated as One Hour as per ASTM E-119.
Here is the list of all the tests Desert Crete must pass to be approved as a walking deck system per AC-39.
3.1 Weatherometer Test: See Section 4.1.
3.2 Accelerated Aging Test: See Section 4.2.
3.3 Fire-classified Roof-covering Test: See Section
3.4 Tensile and Elongation Test: See Section 4.4.
3.5 Bond-strength Test: See Section 4.5.
3.6 Abrasion Test: See Section 4.6.
3.7 Percolation Test: See Section 4.7.
3.8 Water-absorption Test: See Section 4.8.
3.9 Chemical-resistance Test: See Section 4.9.
3.10 Freeze-thaw Test: See Section 4.10.
3.11 Low-temperature Flexibility Test: See Section
3.12 Concentrated Load Test: See Section 4.12.
3.13 Wind-uplift Test: See Section 4.13.
3.14 One-hour Fire-Resistance Rated Construction
(Optional): See Section 4.14.
3.15 Impact Resistance: See Section 4.15.
3.16 Physical Properties: See Section 4.16.
As you can see, there’s a lot to pass…it’s a tough series of tests that many can’t meet.
One coating notably absent from the ICC-ES list of walking deck manufacturer’s is a local competitors manufacturer. Nevada Coating Systems of Rancho Mirage is the coating system of choice for DeckTech, Inc of Grover Beach. So imagine my surprise when DeckTech launched their newly redesigned website and at the page linked to above, they say ” Decktech utilizes the NCS Granite II system, which is unlike any other, and offers a class A fire rating and…” I am not aware of any Class A ratings as defined by ASTM’s E-108 standard or UL’s 790 standard or any reports at ICC-ES that NCS has, at least, that is recognized by a building authority. NCS Granite Deck is unlike any other, just read their hazardous material warnings like this one below at their website here. Nevada Coating Systems does not say anywhere on their website that their materials are Class A. So where does DeckTech get that information from to make such a claim? We want to know and so should you…
2. Hazards Identification
CAUTION! Color: Yellow Form: liquid Odor: Slight.
Toxic gases/fumes are given off during burning
Special Fire Fighting Procedures: Firefighters should be equipped with self-contained breathing apparatus to
protect against potentially toxic and irritating fumes.
Toxic fumes? Really? Ask yourself if you want a deck coating that emits toxic fumes during burning…Desert Crete does not burn, much less emit toxic fumes.
Another concern-toxicity to the environment…doesn’t sound “green” to me…
12. Ecological Information
Ecological Data for Aspartic Ester
Biodegradation: 30 %, Exposure time: 28 d, Not readily biodegradable.
Acute and Prolonged Toxicity to Fish: LC0: > 87 mg/l (Zebra fish (Brachydanio rerio), 96 h)
Acute Toxicity to Aquatic Invertebrates: EC0: 96.8 mg/l (Water flea (Daphnia magna), 48 h)
Toxicity to Aquatic Plants: EC50: > 41.2 – < 84.2 mg/l, (Green algae (Scenedesmus subspicatus), 72 h)
Toxicity to Microorganisms: EC50: > 10,000 mg/l, (Other bacteria)
Ecological Data for Aliphatic Carboxylic Ester
Acute and Prolonged Toxicity to Fish: 38 mg/l (Fathead minnow (Pimephales promelas), 96 h)
15. Regulatory Information
United States Federal Regulations
OSHA Hazcom Standard Rating: Hazardous
US. Toxic Substances Control Act: Listed on the TSCA Inventory.
US. EPA CERCLA Hazardous Substances (40 CFR 302):
So here is a simple challenge; ask for their ICC-ES Report for pedestrian traffic decks. You can get ours for Desert Crete at the link above…ask DeckTech for their ICC report. If they don’t have one, it’s not Class A rated for walking decks as per AC-39 requirements for an ICC-ES report.
If you don’t think fire resistant construction is important, ask your building code official if it is to them and ask them what system they’ll accept for your deck. Desert Crete with an ICC report, or Granite Deck, without a report.
Should we have somehow missed their report at ICC, we’ll apologize. But we won’t have to apologize for selling you a proven traffic coating system like Desert Crete. You make the decision-keep your home safe with Desert Crete, or risk letting it burn when embers land on a deck that may ignite.
The first question for deck coatings should be “Got an ICC report?” When they say “No.” You should say” Thank you, but no thank you. ”
Call us and see the difference between concrete based fire resistant decking from Hill Brothers and Decktech’s Nevada Coating Systems Granite Deck.
Call me, Bill Leys at 805-545-84300. I’ll bring samples of their product and ours, then you decide.
Don’t get burned, be sure
