AVM Industries AVM Primer 570 SB

Over new or existing concrete substrates, masonry, existing mortar, exterior grade plywood, metal and gypsum.

• Do not use over ponding or standing water, snow or ice. Use in well-ventilated areas and avoid breathing vapors. The solvent in the primer attacks polystyrene insulation.
• Do not apply AVM Primer 570-SB when rain is imminent. Do not allow AVM Primer 570-SB to puddle, as this will lengthen drying times. Cold weather will extend drying times.

Project Conditions

• All surfaces to which the AVM Primer 570- SB is applied to must be sound, stable, dry, with an even finish and free from dust, loose debris, grease, curing agents, etc. Concrete surface profile (CSP) should be 6 or smoother. If necessary, grind or apply a parge coat using AVM Crete 6200. Do not apply to frozen substrates.
• Structural concrete must be cured for at least 72 hours. Lightweight structural concrete must be cured for at least 14 days. Install the AVM Primer 570-SB over smooth concrete blocks (CMU). If the blocks are rough or the mortar joints are tooled, a parge coat may be necessary. If needed, parge with AVM Crete 6200 to make surfaces smooth. Allow parge coat to dry before the substrate is primed and the membrane is installed.

System Application

Application instructions

Vary based on type of application and the type of surfaces it’s being applied to.

• Ready to use – do not dilute
• Solvent Based – use with adequate ventilation
• Light mixing is recommended before use.
• Apply materials in dry weather, when ambient temperatures are between 25°F and 100°F. Do not leave exposed to U.V. Cover with membrane as soon as possible.
• Apply AVM Primer 570-SB at the rate of 350-450 sqft per gallon with a low pressure sprayer. Do not pour the AVM Primer 570-SB directly onto the substrates.
• Application of the AVM Primer 570-SB should be limited to an area that will be covered by a waterproofing membrane the same day. If the application area is not covered by a waterproofing membrane the same day, Primer 570-SB must be reapplied before installation of the waterproofing membrane.
• Allow AVM Primer 570-SB to completely dry before applying the membrane. The entire surface should be dry, but tacky. High humidity, cooler temperatures and porous substrates will need additional drying times.
• Warn personnel against hazards of materials to skin and eyes. Note other hazardous conditions on the job that might require special protective gear and or any other special protective or safety procedures.
• Protect adjacent surfaces which could be damaged during the application procedure.

Quality Control

• Visually inspect all coated surfaces to ensure a full and proper coating application, especially at corners, drainage scuppers and hard-to-reach areas.
• All unsatisfactory areas shall be re-primed prior to waterproofing system application.
• If over 24 hours, re-prime.

Protection of Installed Work

The completed section shall be protected from all pedestrian traffic for the first 24 hours after application and until the surface is sufficiently cured. (The amount of drying time may vary depending on temperature and humidity conditions) Typically, light foot traffic may resume after 4-6 hours. Clean Up Tools may be cleaned with solvent.
