Adhesion
Portland cement; minimum 200 PSI. Asphalt; dependent on tensile failure of substrate
Skid Resistance
Minimum 45 (ASTM E303) in units (British pendulum)
Reflectivity
200 millicandella minimum initial reading when applied per VANGUARD specifications
Composition
Comprised of resins, reactive monomers, pigments, glass beads, and fillers. Exact composition is at the manufacturer's discretion. The material is resistant to ultra-violet light.
Installation
Truncated domes and all related installed surfaces to be installed according to manufacturers specifications. All detectable warning surface installations shall be at minimum, at least as non skid as the surrounding pedestrian surfaces.

Asphalt surfaces shall be composed of oil based bitumen. Coal tar asphalt is not acceptable, nor warranted. Asphalt must cure minimum 25 days prior to VANGUARD installation to insure proper bonding of all surfaces. This allows tensile strength properties of both materials to more closely approximate each other. Any asphalt areas requiring detectable warning installations shall be compacted with vibratory rollers or approved compaction equipment in addition to standard local conditions to provide maximum compaction of asphalt allowing the greatest adhesion.
Seal Coat
VANGUARD products shall not be placed on asphalt or coal tar sealers. If surface has been sealed, grind entire area to be installed to remove all sealers.
Concrete
Minimum compressive strength 2,500 PSI. Concrete must cure for 15 days prior to VANGUARD installation to insure proper bonding. All concrete coloring/additives shall be integral, not surface applied. All “surface curing” compounds or sealers shall be removed by method of grinding on any concrete that is less than 6 months old before VANGUARD products are installed. Surface finish should be medium broom finish for maximum adhesion.
Surfaces
All surfaces to be clean and dry.
Temperatures
Surface temperatures should not exceed 88 degF, or be below 35 degF. Adjustments should be made in appropriate mixing ratios for extreme temperatures. Some regional adjustments may also be required due to climatological discrepancies.
Installation Warranty
VANGUARD Detectable Warnings are warranted to not lose more than 5% of their surface installation/adhesion, color retention or non skid characteristics over a 5 year period (occasional cleaning/pressure washing is recommended), assuming installation as per manufacturers specifications, and surface criteria. Detectable Warnings are not a driving surface, nor are they intended to be driven on. Any damage caused by "dry steering" or similar is neither implied or covered under this warranty. Surface coloring agents or sealers (see “concrete” section above) will alter this warranty.
