REDUCE SAGGING IN YOUR
WATERBORNE COATINGS

How to Solve Sagging Challenges IN
Waterproofing, Metal & Wood Coatings 

Are sagging edges and uneven finishes affecting your coating quality?

In waterproofing and metal coatings, sag resistance is critical—especially when working with high film builds or vertical applications. Without the right rheology control, your coatings can slump, drip, or dry unevenly, leading to rework, customer complaints, and wasted materials.

 

The Challenge: Sag resistance without sacrificing flow

Waterproofing and metal coatings often require high-build applications—but formulating them without sagging, cracking, or poor drying is difficult:

  • Thick layers tend to slump before curing.
  • Spray applications on vertical or uneven metal surfaces lead to inconsistent coverage.
  • Traditional thickeners can interfere with flow and levelling, creating application headaches.
  • Many conventional additives are petroleum-based, raising sustainability concerns.
