Abrasive-Sweep-Standards-For-Shop-Primed-Steel-Surfaces

Product catalog summary

Foreword
The document outlines the importance of the type and condition of shop primers on steel surfaces, which affect the performance of subsequent paint coatings. The degree of surface preparation required varies based on the vessel area and paint type. The standards illustrated in this document are derived from intact shop primers and recommend using abrasives with a particle size of 1.0mm to 0.2mm.

Preparation of Shop Primed Surfaces Before Abrasive Sweeping
1. Fresh water wash to remove dirt and salt contamination.
2. Degrease using SSPC-SP1 solvent cleaning.

Treatment of Corrosion
Corroded areas should be prepared according to recognized standards such as ISO 8501-1:1988 (Sa 2½), SSPC-SP10, BS 4232 Second Quality, or JASh2.

Pictorial Standards - Abrasive Sweeping
The document provides pictorial standards for three grades of abrasive sweeping:
- STANDARD AS.1: Light abrasive sweeping
- STANDARD AS.2: Medium abrasive sweeping
- STANDARD AS.3: Heavy abrasive sweeping

Pictorial Standards for Different Primers
The standards are illustrated for untreated and treated surfaces with Red Oxide, Green, and Grey primers, showing the effect of each abrasive sweeping standard.
