Accolades and Thank You's

I recently read a great article on the subject (of decks).  Small world?  site It is your article in my February 2010 issue of The Journal of Light Construction. In fact I color scanned it and may risk violating copyright laws by distributing copies to boards who are plagued with elastomeric deck problems and need to think about tearing them out and starting over.  Attorney Glenn Youngling 2/21/2010

     "Never underestimate the power of wind driven rain to penetrate the building envelope."
    "The common law of business balance prohibits paying a little and getting a lot.  It can’t be done.  If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better."

    "Wood decks are just organized kindling" -firefighter in YouTube video

    Need a new deck? Replacing a wood or composite deck? Is your old waterproof roof deck needing repairs or replacing? recommends the use of solid surface Division 7 Pedestrian Traffic Coatings/decking.

    Solid surface decking offers considerable advantages over traditional wood decking and composite decking.

    There have been a long history of recalls of various brands of composite decking, that fail in the sun and rain.

    pe and exotic wood decking is expensive.  Redwood decking is expensive and these wood decks need a lot of maintenance-sand and seal every year...who wants to do that? Add in the risk of splinters...and solid surface splinter free low maintenance decks look very favorable. 



    Solid surface decking-concrete based systems offer Class A fire resistant ratings as well as "One Hour" fire ratings (some not all do) as per ASTM E-108, UL790 and or ASTM E-119 requirements. 

    Solid surface Pedestrian Traffic coatings offer waterproofing for roofs over living spaces as well as being able to be walked on. Using wood or composite decking requires a waterproofing system AND the deck for traffic.   

    Solid surface pedestrian coatings are far easier to maintain and less expensive to own. A typical wood or composite deck has an estimated life span of 15-20 years. A solid surface decking system made of concrete is expected to last 25-30+ years.

    Solid surface pedestrian traffic coatings don't need yearly dreaded maintenance of sanding and staining and sealing. No splinters, no nails popping out to catch bare feet. With a solid surface deck system, you'll need to have most painted about every 3-5 years.

    Come explore the ways Division 7 Pedestrian Traffic coatings can make your home safer from fire, easier to maintain and help maintain or even increase it's value!
