Expert Verdict — Reviewed by the SuperArbor Pro Desk
Plastic cement is a helper, not a fix: use Pro-Grade #151 to back up flashing membranes and seal laps in horizontal details, never as the primary waterproofing on vertical surfaces or ponding areas. Match the grade to the weather - summer grade in heat, low temperature grade for cooler work. Keep trowel coats thin and feathered so the cement does not soften or bleed through modifiers.
Asphalt-based cement: keep away from open flames and ignition sources, and follow the safety directions on the label during trowel application.
