Auto Life 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 Auto-life 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 Auto-life 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 Auto-life evenly over the entire deck resulting in a 14 ± 2 dry mils (355 ± 51 microns) thick membrane. Allow Auto-life to cure a minimum of 16 hours.

 Phase 4: Over ramps, turn radii, and other heavy traffic areas only, apply catalyzed Auto-life 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 Auto-life to cure a minimum of 16 hours. Apply a second coat of catalyzed Auto-life 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 Auto-life to cure a minimum of 16 hours and a maximum of 48 hours.

Phase 6: Apply the third coat of catalyzed Auto-life or Lifeglaze Topcoat at the rate of 1 gallons/100 sq. ft. (0.41 liters/mÇ) over the cured Auto-life 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 Auto-life 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.

As a Finished System:

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.

1. Do not apply Auto-life coating systems or products over the following: split slabs with buried membrane, sandwich slabs with insulation, slabs over unvented metal pan, suspended pool decks, swimming pools, magnesite, lightweight concrete, asphalt surfaces, asphalt overlays and where chained or studded tires may be used.
2. Concrete must exhibit 3000-psi minimum strength. Concrete surfaces to be coated must be trowel finished in compliance with the American Concrete Institute (except that hand troweling is not required), followed by a fine hair brooming, left free of loose particles, and shall be without ridges, projections, voids and concrete droppings that would be mechanically detrimental to coating application or function.
3. New concrete must be cured for 28 days. Concrete cleaning (see General Guidelines). Equipment should be cleaned with an urethane grade environmentally safe solvent, as permitted under local regulations, immediately after use.
4. Life Deck Coating Systems should not be subjected to rising water tables or hydrostatic pressure on slab-on- grade decks. Uncured materials are sensitive to heat and moisture. A continuous coating application should ensure a deck with no lines or streaks. The substrate must be structurally sound and sloped for proper drainage.
5. Life Deck assumes no liability for substrate defects. Field visits by Life Paint personnel are for the purpose of making technical recommendations only and are not to supervise or provide quality control on the job site.
