Surface preparation is the essential first stage treatment of a steel substrate before the application of any coating, and is generally accepted as being the most important factor affecting the total success of a corrosion protection system.. The performance of a coating is significantly influenced by its ability to adhere properly to the substrate material.
Standards referenced in the NCC, BCA and PCA fall under the deemed-to-satisfy provisions and compliance with these Standards represents the most common method of satisfying the performance requirements which covers both Commercial and Residential sectors.
Material Laboratory of the Construction Section. Methods of testing fall into four main groups: 1. Those which follow a national standard (not included in this manual). 2. Those which mainly follow a national standard but have been modified for use in our laboratory (only the modifications are in this manual). 3.
