What makes Dec-Tec unique?
Dec-Tec membranes are waterproof, slip-resistant, and fire-retardant. They undergo strict quality control and are tested to ensure UV stability, long lifespan, and minimal maintenance.
What are PVC single-ply vinyl decking and roofing membranes?
These are PVC-based products that act as both a roof and a walking surface. They waterproof and protect structures while offering design appeal and durability.
What warranty is provided with the Dec-Tec membrane?
Dec-Tec membranes come with a 10-year product warranty and an optional 15-year warranty when installed by certified professionals.
Who installs Dec-Tec?
Certified installers across North America are trained by Dec-Tec to ensure correct installation and long-lasting performance.
Where do I buy Dec-Tec?
Dec-Tec products are available through their dealer network. Customers can find local dealers or contact Dec-Tec directly for support.
How do I obtain samples of Dec-Tec membranes?
Samples can be requested directly through Dec-Tec’s website.
What are acceptable substrates?
Acceptable substrates include:
- Plywood (APA-rated)
- OSB (Oriented Strand Board)
- Structural Concrete Decks
- Lightweight Concrete with APA-rated underlayment (plywood/OSB)
- Cementitious Boards
- Rigid Insulation Panels (with approved cover board)
Can Dec-Tec adhere to itself?
Yes, it can. Dec-Tec can overlap and weld itself to ensure watertight seams.
How do you apply the Dec-Tec system?
The membrane is adhered using a solvent-based adhesive, heat-welded at the seams, and flashed at edges. This ensures waterproofing and slip resistance.
Is the metal drip-clad flashing mechanically fastened or adhered to the substrate?
It must be mechanically fastened (screwed/nail fixed), not glued.
Can you use adhesives other than Dec-Tec for this system?
No. Only Dec-Tec approved adhesives should be used for warranty and performance assurance.
How do you attach the substrate to the wall so the vinyl should not break at corners?
Use an APA-approved underlayment installed flush against the wall. Dec-Tec must be properly flashed and welded at corners to prevent breaks.
In what temperatures can the glue be applied?
Dec-Tec adhesives can be applied in temperatures as low as -6°C (20°F) but work best in moderate weather.
Does the deck have to be dry to put the glue down?
Yes, the surface must be clean and dry before applying adhesive.
Should the glue be dry before you put the membrane down? How long does it take to dry?
Yes. Adhesive must be tacky-dry (not wet) before membrane installation. Drying time depends on temperature and humidity, typically 10–20 minutes.
What is the spread/rot system?
This is the system Dec-Tec uses to protect against rot and water damage by ensuring proper water drainage and preventing moisture buildup under the membrane.
Can Dec-Tec membranes withstand foot traffic?
Yes. Dec-Tec is durable and designed as a walking surface, suitable for decks, balconies, and walkways.
Is the membrane slip-resistant?
Yes. Dec-Tec membranes are slip-resistant and meet international safety standards, making them safe for residential and commercial use.
