AL Flex Waterproofing System for Plywood Decks ICC ESR-2701
Life Deck AL Flex (Acrylic Flexible Lath) is a metal lath reinforced deck system installed with a series of three separate applications. AL Flex combines a flexible, waterproofing, resin bonding fiberglass between two cementitious applications. The AL Flex waterproof system is recommended in lieu of the AL System where flexibility is essential during new construction settling, or where soft soil exists, to resist cracking. It is bonded together with specially formulated acrylic emulsion and sealed with Life Deck 10 Series, or Heat Reflective 28 Series, 100% acrylic top coat. When using the 28 Series top coat, the surface temperature can be reduced by up to 30% as compared to the 10 Series.
The AL Flex works only on plywood walking decks. It is recommended for the discriminating contractor or building owner who demands the finest in design, strength and durability. The AL Flex deck is ideal for areas with heavy traffic or in cases where elimination of plywood seams is essential. Life Deck AL Flex has been designed for balconies, corridors, stairs and landings.
It is regularly specified for hotels, condominiums, apartments and office buildings. It can be stapled through most old deck systems to provide an excellent method for the rehabilitation of problem surfaces.
Life Deck AL Flex System Advantages
Note: Should deck coating not be completed in one phase or to allow for other construction trades, deck should be covered to avoid being damaged and to keep clean. It may be necessary to power wash the deck to dislodge any construction debris or any other foreign matter.
Plywood decks must be at least 5/8” CDX exterior grade. The deck should be tongue and groove and properly blocked and nailed (glued & screwed is best) and meet local building codes. Plywood shall have a maximum span of 16”. Slope must be a minimum of 1/4” per linear foot. Please refer to Notice to Customer for Deck Coatings.
Flash at wall-to-deck with 4” x 4” facia with 2”x4” minimum 26 gauge bonderized sheet- metal overlapped at least 4” and caulked in front and back with a Life Deck approved sealant such as RainbusterTM 900 or equivalent. If the flashing is not bonderized it must be etched so that coating will bond . Nail all flashing every 4”.
Be sure the surface is clean, dry and free of grease, paint, oil, dust or curing agents.
Option: Plywood Joints and Seams Cracks or seams should be cleaned out, dry and free of debris. Life Deck Seam Tape (self adhering) should be laid out over all cracks, seams, plywood joints and at flashing.
After the slurry coat is dry, you may lay out a pattern using 1/2” or 3/4” Life Deck pattern tape. Spray texture over tape and remove within 24 hours. This will leave an impression in the surface. The pattern can be used to enhance the look and create a tile or flagstone effect.
Temperature/Weather: Do not install Texture Crete if the temperature is below 55 degrees. Rain will wash away Life Deck acrylic products. If inclement weather threatens, cover deck to protect new application. Do not allow any Life Deck product to freeze.
Maintenance: Most stains clean up with TSP and water. Use only a bristle scrub brush. The Life Deck AL System textured deck should have annual inspections and be resealed with Life Deck 10 series top coat every 2 to 3 years depending upon ultraviolet exposure from the sun or sooner if recommend by your applicator.
Repairs: Repairs may be done by grinding off the damaged area and replacing the material as written in this spec. Plywood must be replaced if necessary and lath must be restapled to integrate into the remaining surface.
Life Deck AL has a five + five year limited warranty. After 5 years, a Life Paint Representative must be contacted to inspect and recommend maintenance to the project before an additional 5 years are given.
It is valid only if the complete AL system is installed by a factory trained, licensed contractor and maintenance specifications are followed along with annual inspections. Life Paint will replace any defective AL product proven to be the cause of deck failure.
Warranty shall not exceed the replacement cost of the defective material and does not include labor. All claims regarding product defects must be presented to Life Paint within 90 days of the alleged defect. The absence of a written claim during this period will constitute a waiver of all claims against the manufacturer.
