Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose SBS Polybase where a robust, elongation-friendly base ply is required and cold adhesive application is preferred over torching, since it bonds with hot asphalt or Elevate Multi-Purpose MB Cold Adhesive. Verify that the deck or substrate is a solid, moisture-controlled foundation before installation. Order rolls based on field area plus a lap allowance, and keep the cold adhesive within its stated storage and application conditions.
When applying with hot asphalt, use heat-rated gloves and protective clothing and follow safe kettle and mop-handling practices to prevent burns.
