Ensuring The Success Of A Project Through The Optimal Selection Of Coating Techniques

Reviewing NACE,-SSPC, ISO Surface Preparation Standards so the owner knows what they’re getting, the contractor knows what they’re supplying, and the paint manufacturer knows what they’re warranting

Exploring the three components of a perfect surface preparation to ensure performance

Understanding the logistics of removal of thick coal tar (coating) and tape to identify the most time-effective technique

What is Flash Rust, Rust Back, and Rust Bloom?

Two new posts on Rust Back, Rust Bloom, and Flash Rust were added in March, 2014, along with flow charts and new pictures.

How do you know when to paint?

Test Protocol for Corrosion Inhibitors or Cleaners for Flash Rust

A Test Method for Corrosion Inhibitors or Cleaners for Flash Rust has been posted on flashrust.org.

Dr. Frenzel prepared this protocol from a Proprietary Inhibitor and Cleaner in a generic form. Specific concentrations should be changed to those of the inhibitor/cleaner under consideration.

This document provides guidelines for testing Proprietary Inhibitor and Cleaner used according to its manufacturer’s instructions. These test guidelines are necessary because applicable ASTM test procedures specifically require that tests be conducted in a manner consistent with the manufacturer’s instructions for use of the product tested. Since the performance of the product is application sensitive, this step by step test procedure should be helpful in the evaluation of its performance in various surface preparation methods.

Panel Preparation

Steel test panels should be used when testing for rust formation. The size of the panels may vary but generally are 3″ x 5″ x 0.25″. Ten panels per coating is generally adequate to test for both salt removal and coating adhesion.

All panels, with the exception of the control panel, should be immersed for 100 hours in an 8-10% weight by weight (w/w) sodium chloride solution to accelerate rust development. The control panel which was not immersed in salt water solution will establish the baseline reading for salts and other contaminants levels.

In addition to the control panel, leave one test panel out of the blast sequence to measure the salt levels deposited after 100 hours of immersion. The other eight panels will be blasted to SSPC-SP10 (NACE 2)(Near White) using the either the water-abrasive blasting method or the dry blast method.
