Acrylic Patching Compound Built for Real-World Roof Repairs
When you need a fast, flexible fix that holds up—1881 delivers.
QUIK-SHIELD® 1881 is a high-performance, butter-grade acrylic patching compound formulated for pros who demand results on the job. Designed to seal, bond, and flex under pressure, it’s the field-tested go-to for filling gaps, joints, cracks, and seams on roofing substrates.
Engineered with 100% acrylic polymer resins, this water-based, non-toxic formula cures into a water-resistant membrane with serious staying power—even in harsh environments.

Passes 180° bend over ½” mandrel at -5°F—holds strong where other patchers fail. - Fast, Clean Application
Brush, trowel, or hand-apply. Smooth texture, butter-grade feel, and low mess. - Buildable & Reinforceable
Compatible with polyester fabric for reinforced patching where needed. - Weather-Resistant
Once cured, forms a durable membrane that resists water, shrinkage, and cracking.
