Deck Tech of Grover Beach, Their Granite Deck Burns In Fire Test, Our Desert Crete Doesn’t.

A local competitor in San Luis Obispo puts down Nevada Coating Systems Granite Deck . The manufacturer claims it can be put down on decks, which you could if you didn’t know better…

One of my clients had received a bid from Deck Tech, Inc of Grover Beach. They specified “Granite Deck” (oooooh, it sounds like tough stuff doesn’t it?) to install for the client. The client was almost sold that day, but did call Central Coast Waterproofing for a bid.

We came and looked at the job, discussed the products and showed the client our ICC report for Desert Crete. We left a sample of the Desert Crete so they could compare it to the NCS Granite Deck…I told the client that Granite Deck has no testing or evaluation to certify it’s use a as a deck coating, only manufacturer claims…(it is not listed at ICC-ES’ website as a Fire Resistant Traffic coating)

The client is a smart guy, he did some research, investigating my claims and I got an email back from him, he did his own “testing” of the NCS Granite Deck and Desert Crete…here are the clients own results.

“I tried to reach the fire department about fire-proof ratings, etc, but was unable to get through. So, I tried lighting the sample you gave me and also the sample from decktech: the decktech material catches on fire after exposure to a flame from a cigarette lighter; your material does not. This is a very important consideration for us.”

If having deck coating materials that don’t catch on fire is important to you, please call Central Coast Waterproofing today at 805-545-8300.

We have asked the manufacturer of Granite Deck some questions…here’s a link to their NCS Granite Deck  info sheet at their website. Open the tab that says material safety and read that closely regarding firefighting safety.

I sent this quick email to Nevada Coating Systems, I’m waiting for their answer…

A client is considering Granite Deck installed by Deck Tech here in Grover Beach. I showed them Desert Crete to compare and we discussed fire resistance of the 2 materials. He did his own “test”…

“I tried to reach the fire department about fire-proof ratings, etc, but was unable to get through. So, I tried lighting the sample you gave me and also the sample from decktech: the decktech material catches on fire after exposure to a flame from a cigarette lighter; your material does not. This is a very important consideration for us.”

Why are you selling a product that goes on decks over living spaces that can catch on fire? Class A decking/roofing is typically required.

Do you have any fire tests showing the product complies with ASTM E108?

Could you please send some finished samples that we can do our own fire tests on?

Please send to PO BOx 14438 San Luis Obispo CA 93406  Thanks, Bill Leys

As of 4/26/2011 I haven’t heard anything back from Nevada Coating Systems. I think it’s safe to say that their safety sheet says it all and without a ICC-ES Report that certifies deck coating’s fire resistance; why take a chance?
