Characteristics
Maximum-Stretch® is a white elastomeric, acrylic, rubberized roof
coating and sealant with 650% elongation that resists cracking and
peeling. With 88% light reflectivity the bright white finish reduces
surface temperatures resulting in a reduced cooling cost and
thermal expansion and contraction. Designed for low-slope roof
maintenance on metal, built-Up roofing, rolled roofing, modified
Bitumen concrete, EPDM, and wood.

Surface Preparation
All surfaces must be sound and free of frost, dirt, grease, oil, spalled
areas, loose nails, screws, sharp protrusions, or other contaminants that
will hinder the adhesion of the membrane installation. Clean loose dust
and dirt from the surface by brushing or wiping with a clean, dry cloth
brush or broom. Do not cover wet or soft spots until dry or replaced.
Surface must be completely dry before coating.
Application Methods
Apply between 50° - 90° F on a warm dry surface. Surface temperature
must be 5° F higher than the dew point and rising
• Brush: Nylon/polyester
• Roller: 3/8" - 1/2" nap nylon/polyester
• Sprayer: Always use airless equipment (see spray application section
below for details)
Application Instructions
Review product Application Guide before proceeding. Conduct a test
patch to ensure proper adhesion.
Maximum-Stretch® should be applied on a properly and adequately
drained roof and the roof surface must be clean, dry and in savable
condition. Some areas may require periodic preventative maintenance.
Ames Research Laboratories Technical Service Representatives are
available to assist in determining the correct Maximum Stretch® Roof
System for your specific roof. All specifications are suggestions only.
• Spray or pour out Maximum-Stretch® onto surface. Spread in 1- or 2-
gallon increments if applying by squeegee, push broom or roller
• Even up the coating application with a roller as needed to maintain
a uniform thickness
• Work on manageable sections of roof allowing you time to properly
apply the materials prior to materials beginning to dry
• If spraying it may be advantageous to back roll through the first coat
during application to infill rough surfaces. Always contact Technical
Services when in doubt
Spray Application
• Airless Equipment sizing should be a flow rate of 1.0 – 2.0 GPM, 2500
to 3000psi, Heavy Duty Reverse-clean tip (without diffuser pin) sizes
629 (12” fan .029 orifice size) to 633 (12” fan -033 orifice size) Hose size
3/4” reduced to 1/2” before connection to gun swivel
• If airless has a machine filter in addition to the intake rock screen we
recommend either a 40-mesh filter or temporarily removing the
machine filter cartridge altogether.
• Airless equipment should be cleaned after use without delay
• Contact Ames Research Laboratories Technical Service Department
for more information, guidelines, and recommendations on spray
application.
