Expert Verdict — Reviewed by the SuperArbor Pro Desk
MBR Bonding Adhesive is the go-to when hot asphalt is prohibited, undesirable or impractical, such as on occupied or sensitive buildings. Because it is 100% solids, coverage depends on applied film thickness, so meter the mix carefully and follow the manufacturer's spread rate. Mix full kits and observe the fast set time to avoid waste.
Two-part chemical adhesives require gloves, eye protection and good ventilation during mixing and application; follow the safety data sheet.
