Paint Defect Diagnosis Guide
A structured way to investigate peeling, blistering, sagging, poor adhesion and other coating problems.
Source-first buying rule
Use this guide to narrow the right product family. For exact coverage, dilution, drying time, compatibility, warranty, safety and other product-specific specifications, use the current manufacturer product page and TDS/PDS/SDS where applicable. If a value is not verified, this website does not invent it.
Diagnose before buying another coating
A visible defect is not automatically proof that the product is wrong. Record the substrate, previous coating, preparation, application method, environmental conditions and when the defect appeared.
Peeling / poor adhesion
Start with substrate condition, contamination, preparation and intercoat compatibility.
Sagging
Check application build, viscosity, application technique and drying conditions.
Blistering
Investigate moisture, substrate condition and the coating system before recoating.
Surface appearance
Check preparation, application technique, film formation and the product's own instructions.
