Where Thin Film Develops

Edges, welds, bolt heads, nuts, corners, pits, crevices and cutouts can receive less effective film than broad flat surfaces. These locations are common early corrosion points.

What a Stripe Coat Does

A stripe coat is applied deliberately to designated details using a brush, roller or other approved method. It works with the full-coat sequence; it is not a substitute for complete system coverage.

Sequence Is Specification-Driven

The contract may require stripe coating before a full coat, after a full coat or at multiple stages. Timing must respect cure and recoat windows, and the stripe material must be compatible with the complete system.

Surface Preparation Still Controls

Stripe coating cannot compensate for inaccessible rust, sharp fabrication defects, weld spatter, oil or inadequate preparation. Fabrication corrections and preparation acceptance occur before coating.

Inspect the Details

Visual inspection should confirm continuity around the required geometry. Dry-film measurement on small or irregular features may require project-specific methods and experienced interpretation.

Document Required Areas

The quality plan can define which details receive stripe coats, product, color where useful, method, sequence and repair expectations. Photographs provide a useful record before full coverage hides the work.
