Application and removal methods
· Air and surface temperature must be 50°F (10°C) and rising. Between 40°F (5°C) and 50°F (10°C) ATM Removable Primer must be used.
· Surface must be completely dry. Moisture bag test should be used to confirm.
· Surface must be free of any contaminants, which may include but not limited to, oils, grease, sand, dirt, dust, loose aggregate, curing compound mud, soil and salt.
· Portland cement concrete curing compound must be completely removed by sandblasting, water blasting or grinding of the road surface. *If water blasting method is chosen a minimum of 24 hours drying time is required before tape installation.
· Do not apply tape directly over deteriorating markings or substrates, or lane delineation devices.
· Tapes or Rumble Strips applied directly over seams or joints must be cut through 1" on both sides of the seams or joints to prevent de-bonding of large sections of tape. New asphalt should be allowed to cool to a minimum temperature of 100°F before installation.
· Always use butt splices.
· Firmly tamp longitudinal tape in the same direction as tape was applied on the initial pass. A minimum of three passes total are required. Use a tamper device with a minimum 200 lb. (90kg) load and a tamping surface a minimum 2" wider than the width of tape being applied. Never twist the tamper device during tamping. Repeat tamping as necessary to insure tape has completely conformed to the road surface.
· Road surface must be completely dry for a minimum of 24 hours prior to installation of ATM products. The road surface must remain completely dry for a minimum of 24 hours after installation.
· ATM Removable Primer should be used under the following marginal conditions:
1) When air or surface temperatures are expected to fall below 40°F (5°C) 24 hours after installation.
2) Rain is expected within 24 hours after installation.
3) When road surfaces are marginal.
· When removing tape, pull tape at a 90° angle to the pavement.
· Marked roadway can be open to traffic immediately.
If an installer has questions concerning the types of surface that preformed polymer tape can be applied or weather conditions not referred to above, they may contact their local ATM Regional Manager or 252-536-2574 ext.5138.
