Basic nuances and common details
Stability
FT Synthetics products are designed with the GRIPSPOT™ technology for better skid protection for the roofer but product may become slippery due to high moisture, frost, rain, water, dust, debris or other conditions.
Applications
PLATINUM HT-SA must be covered by a primary roof (Asphalt & Synthetic Shingles, Metal Roofing, Tiles, Slate, and Cedar Shakes) within 180 days. For best results HT-SA should be installed on a dry deck when the air, membrane, and substrate temperature is over 40°F (4.4°C).
HT-SA is recommended for roof slope applications 2:12 and above. For steep slope applications (6:12 or greater) or when installing at temperatures greater than 100°F (38°C) it is recommended to blind nail the overlap area as instructed above for cold weather applications.
Installation
The GRIPSPOT™ walking surface features raised fibrous traction spots and smooth channels for shedding water. This provides faster dry times while offering unmatched slip resistance in all types of weather and surface conditions; dry, wet, frozen, and dusty. Platinum HT-SA comes with a silicone treated split-release liner for ease of removal during installation.
