The Single Component (SC Series) coatings are designed to be installed by brush, roller, or sprayer. The Plural component (PC Series) can also be installed by brush or roller after the 2 components are mixed.
GRP offers 10-year labor & materials warranty (10 cents per square foot), 15-year labor & materials warranty (12 cents per square foot), and 20-year labor & materials warranty (15 cents per square foot)
Yes, GRP coatings can be recoated allowing for a warranty extension for 10, 15 , or 20 years
The process typically involves washing the substrate, applying a primer if necessary, and then applying the base and top coats. The coating forms a seamless, monolithic layer that adheres well to properly prepared substrates.
Yes, they are suitable for a wide range of roofing substrates, including BUR, aged TPO & PVC, concrete, metal, and modified bitumen.
They provide a durable, energy-efficient solution for flat and low-sloped roofs. Urethane coatings offer superior waterproofing, UV resistance, and strong hail resistance. They contribute to thermal performance by minimizing heat transfer and reducing cooling loads in hot climates.
Annual maintenance is crucial and required for all roof types. This includes drain cleaning, debris removal, and checking for any signs of damage or wear and applying any necessary repairs. Click HERE for more info.
There are two primary types: aliphatic and aromatic. Aliphatic coatings are UV stable and color-retentive, while aromatic coatings are more cost-effective but may yellow over time.
ALIPHATIC vs. AROMATIC SPRAY SYSTEMS
The main difference between aliphatic and aromatic coating systems lies within their chemical structure, which influences performance, durability, UV stability and cost.
CHEMICAL STRUCTURE
Aromatic: Based on aromatic isocyanates (e.g. MDI or TDI).
Aliphatic: Based on aliphatic isocyanates, which possess open-chain structures (e.g. HDI or IPDI).
UV RESISTANCE
Aromatic: Visually, aromatic systems have the tendency to change color and chalk when exposed to sunlight. A UV-stable topcoat can be applied to aromatic systems to provide UV stability.
Aliphatic: Aliphatic systems offer excellent UV resistance and maintain color and gloss even with prolonged sun exposure. Aliphatic coatings are recommended as a top surface for roofing applications.
DURABILITY AND PERFORMANCE
Aromatic:
• Very tough and impact-resistant
• Faster cure times
• Commonly used in roofing, industrial, and underground applications
Aliphatic:
• Excellent UV resistance with good physical properties
• Superior aesthetic and weathering properties
• Ideal for roofing, balconies, and decks
COST
Aromatic: More economical – used where UV resistance isn’t needed.
Aliphatic: More expensive due to a complex chemistry and enhanced weathering resistance – but it’s more bang for your buck.
TYPICAL USES
Aromatic:
• Roofing as a base coating
• Waterproofing
• Industrial tank coatings
Aliphatic:
• Roofing as a top coating
• Balconies, decks, parking structures
• Decorative outdoor applications or high-visibility surfaces
