The Autolife vehicular deck system is an urethane, liquid applied, moisture cured waterproof system. The system utilizes an epoxy primer and one easy to use high tensile aromatic urethane to complete the system. The Autolife System is a user friendly application of an elastomeric coating that is tough and durable. The Autolife System can be applied to protect surfaces against spalling, freeze/thaw damage, and chemicals commonly encountered on vehicular traffic decks. It is designed to expand and contract with normal structural movements and will not soften in heat nor embrittle in cold. Installed and maintained properly, the Autolife Vehicular Deck System will ensure years of service and high performance as a waterproofing system.
Phase 1: Check area of application to ensure that it conforms to the substrate requirements. Apply a two part paste consisting of LD-220 and LD-50 (0.9 18.9 liters). Mixing ratio is 1/2 pint of LD-50 to 1 gallon of LD-220 (0.24 liters per 3.78 liters) or 1 quart LD 5 gallons of LD-220 (0.9 liters per 18.9 liters). mix more material than can be used in 20 minutes. Bridge the joints, cracks, and flashings with 3″ (7.5 cm) Polyester Tape, pushing it into the paste with a trowel. Over Polyester Tape, apply a stripe coat of the LD-220 and LD50 mixture (or compatible sealant) and taper it onto the adjacent surface. Allow the surface to cure for 6 to 8 hours.
Phase 2: Prime the surface with LD PRM Autolife Primer at a rate of 1 gallon (mixture of Part-A & Part B) /300 sq. ft. (0.14) liters/mÇ). Apply using a brush or phenolic core roller. This will result in a 3 dry mils (76 microns) thick membrane. Allow to become tack free before proceeding to Phase 3.Steel flashings should only be primed with LD PRM2180.
Phase 3: Apply catalyzed Autolife to substrate at a rate of 1 gallon/80 sq. ft. (0.51 liters/mÇ). For best results use a notched trowel or squeegee. A phenolic core roller may be used but extra care should be taken to prevent air bubbles Spread mixed Autolife evenly over the entire deck resulting in a 14 ± 2 dry mils (355 ± 51 microns) thick membrane. Allow Autolife to cure a minimum of 16 hours.
Phase 4: Over ramps, turn radii, and other heavy traffic areas only, apply catalyzed Autolife at a rate of 1 gallon/100 sq. ft. (0.41 liters/mÇ). Immediately broadcast washed, dry, rounded, crystal silica sand, 16 or 20 mesh (0.0331-0.0469 in.; 0.84-1.19 mm), 6.5+ Moh’s minimum hardness at a rate of 10 lbs/100 sq. ft. or to refusal. This coat will result in an additional 11 ± 2 dry mils (279 ± 51 microns) thick membrane, exclusive of aggregate. Before proceeding to
Phase 5: allow Autolife to cure a minimum of 16 hours. Apply a second coat of catalyzed Autolife over the entire surface, including heavy traffic areas, at a rate of 1 gallon/80 sq. ft. (0.51 liters/mÇ). Immediately broadcast washed, dry, rounded, crystal silica sand, 16 or 20 mesh (0.0331-0.0469 in.; 0.84-1.19 mm), 6.5+ Moh’s minimum hardness at a rate of 10 lbs/100 sq. ft. This coat will result in an additional 14 ± 2 dry mils (355 ± 51 microns) thick membrane, exclusive of aggregate. Before proceeding to Phase 6 allow Autolife to cure a minimum of 16 hours and a maximum of 48 hours.
Phase 6: Apply the third coat of catalyzed Autolife or Lifeglaze Topcoat at the rate of 1 gallons/100 sq. ft. (0.41 liters/mÇ) over the cured Autolife with aggregate. This coat will result in an additional 11 ± 2 dry mils (279 ± 51 microns) thick membrane. At 70°F (21°C) and 50% relative humidity, allow 24 hours before permitting light foot traffic. Keep all vehicular traffic off the finished Autolife vehicular deck system for at least 72 hours.
The use of LD-51 Hardener will shorten cure time to 6 to 8 hours for each coat.
When applied as directed above, the Autolife vehicular deck system will provide 40 dry mils, (ramps, turn radii, and other heavy traffic areas: 50 dry mils) exclusive of aggregate, of superior waterproofing protection and the assurance of a Class A Fire Rating.
The products in this system contain Isocyanates, Solvent, Epoxy Resin and Curatives.
