Expert Verdict — Reviewed by the SuperArbor Pro Desk
Butter-grade consistency is designed for trowel or hand application in vertical and detail work, making it a good choice for flashing terminations, curbs and penetrations. Apply to clean, dry surfaces and tool the mastic to feather edges for a watertight seal. For extensive seam work, pair with a compatible reinforcing fabric per the project specification.
Follow the product label for ventilation, skin and eye protection, and disposal precautions when applying solvent-free or silicone mastics.
