Adhesion testing is essential before painting surfaces like self-storage roll-up doors to ensure coating integrity. This article covers two quick methods: the Simple Tape Test and the Cross Hatch Adhesion Test. These tests assess paint adherence, identifying potential issues with paint bonding. Results can be compared to ASTM standards for evaluating adhesion quality, ensuring a durable finish.

This guide provides step-by-step instructions on how to properly prepare and paint roll-up doors with wide-spread peeling paint. From cleaning with Zap-It! to priming with Bond-All and applying durable coatings like Chem-Bake or Endura-Crylic, you'll learn how to repair peeling areas and protect your doors from future damage.

This guide offers professional painters a comprehensive approach to evaluating, preparing, and painting roll-up doors using the Chem-Bake® system. It addresses the challenges of SMP coil-coated surfaces, provides tips on surface preparation, adhesion testing, and correct application techniques for achieving a durable, smooth finish on self-storage roll-up doors.

Coil coated steel is a versatile and durable building material widely used in the self-storage industry. This pre-painted sheet metal forms over 90% of structures, including roofs, walls, and doors. Commonly coated with silicone modified polyester (SMP), it offers excellent durability, UV resistance, and weathering. Its smooth surface can be challenging to repaint but ensures long-term performance.

Properly preparing an SMP (Silicone Modified Polyester) coated surface is crucial for achieving a lasting finish. This guide walks you through the essential steps of cleaning and abrading your substrate, from pre-rinsing to applying Zap-It! and inspecting the final surface. Ensure your next painting or clear coating job is a success with these expert tips on substrate preparation.
