Description
AIM #1
High-Performance Urethane Waterproofing & Protective Membrane
AIM #1 is a liquid-applied, moisture-cure urethane coating engineered to deliver exceptional waterproofing and chemical resistance in demanding environments. Once cured, it forms a tough, rubber-like membrane that maintains flexibility and strength under stress, making it ideal for surface applications, buried membranes, and below-grade waterproofing.
Designed for concrete, asphalt, metals, and a wide range of substrates, AIM #1 provides long-term protection against water intrusion, chemical exposure, and environmental attack.
Key Benefits
- Continuous Waterproof Membrane: Forms a seamless barrier against moisture intrusion
- Chemical Resistance: Resists penetration of de-icing salts, gasoline, oils, antifreeze, and many industrial chemicals
- High Tensile Strength & Elongation: Rapidly develops durability with excellent elasticity
- Stress-Resistant: Retains performance after substrate movement or structural stress
- Versatile Installation: Suitable for vertical, horizontal, and pitched surfaces
- Below-Grade Performance: Effective as a buried membrane or below-grade waterproofer
- Fast Curing: Minimizes downtime
- Repairable: Can be easily repaired if damaged
- Reinforcement Option: Compatible with K-CATALYST to increase strength and durability
Typical Applications
- Waterproof basecoat for concrete parking structures
- Buried membrane beneath pavers in plazas, balconies, and recreation areas
- Waterproofing under tank bottoms and fixed equipment
- Protection of chemical dikes and wash-out basins
- Waterproofing for basements, crawl spaces, tunnels, junction boxes, and shower pans
- Coating of gullies, docks, marinas, tile and concrete pipes

Preparation and Application
Surface Preparation
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion. Do not apply if the substrate or air temperature is predicted to drop below 35°F (2°C) within 4 hours after application. The application surface must remain at least 5°F (3°C) above dew point during the application and curing process.
Application
Do not apply AIM #1 to wet, damp, or frozen surfaces. Do not apply if the area cannot be protected from precipitation for at least 4 hours after application. AIM #1 is applied directly out of the container after at least 2 minutes of low speed drill stirring. Do not thin the product. Apply in 2 coats using a soft brush, medium nap roller, or airless sprayer in a smooth, even technique.
Spray Application
Utilize a 45:1 airless pump, a 1/2″ hose, 3/8″ whip and a 31 width tip
Recommended Thickness
40 mils Dry Film Thickness (DFT)
Drying Time
To walk on: Approx 24 hours at 80°F (27°C) and 70% RH
To walk on: With the addition of Andek Accelerator. Approx 3 hours at 80°F (27°C) and 70% RH
Total Cure: Approx 72 hours (to 55 degree Shore ‘A’) at 80°F (27°C) and 70% RH
Total Cure: With the addition of Andek Accelerator. Approx 24 hours (to 55 degree Shore ‘A’) at 80°F (27°C) and 70% RH
Clean up
Equipment may be cleaned after use with xylene or toluene before AIM #1 begins to dry
Storage
Store in a dry area and protect from direct sunlight and freezing. Protect from moisture and foreign materials. Keep container tightly sealed. Shelf life is 2 years from date of manufacture when stored in a factory sealed container between 50ºF (10ºC) and 90ºF (27ºC).
Disposal
Waste disposal must be in accordance with existing federal, state and local environmental control laws. Incineration is the preferred method of disposal.
Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
