The PPC Help Desk

June 13, 2016 Posted by David Hanna Brochures, NEWS No Comments

The PPC Help Desk is designed to provide you with the fundamental principles and practicalities of Protective Coatings. We at Patterson Protective Coatings Ltd will assist you with everything you need, from technical expertise from the project outset to completion. It’s our duty as suppliers of brands such as Jotun, Rustoleum, Tor Coatings, Remmers & Flexcrete to provide you with the knowledge to ensure that the product specified is suitable from the outset.

We pride ourselves on the relationship we have with our clients, so please contact our office and have a chat about any projects you may have relating to Protective Coatings.

In the meantime, we hope you find these links useful.


This table will be an excellent guide for the estimator to accurately predict the volume & cost of the coating.

  • Coatings Calculation Guide

Surface preparation is the essential first stage treatment of a substrate before the application of any coating. The performance of a coating is significantly influenced by its ability to adhere properly to the substrate material. It is generally well established that correct surface preparation is the most important factor affecting the total success of surface treatment. The presence of even small amounts of surface contaminants, oil, grease, oxides etc. can physically impair and reduce coating adhesion to the substrate.

  • Surface Preparation for Coatings

The purpose of this guide is to explain, in terms of modern concepts, the basic requirements for protecting structural steel with paint and metallic coatings, the systems commonly used and their significance in relation to the protective properties required. The emphasis is on the protection of onshore structures, such as buildings, bridges, factories, and industrial plants in which the process environment contributes to the corrosion hazard.

  • UK Guide for Coating Structural Steel

Unprotected steel in the atmosphere, in water and in soil is subject to corrosion that may lead to damage. Therefore, to avoid corrosion damage, steel structures are normally protected to withstand the corrosion stresses during the service life required of the structure.

There are different ways of protecting steel structures from corrosion. ISO 12944 deals with protection by paint systems and covers, in the various parts, all features that are important in achieving adequate corrosion protection.  The attached table will summarise the process that Specifiers should consider when specifying the correct protective coating.

  • Introduction to ISO 12944

COATINGS SUFFER DEFECTS AND FAILURES for a number of reasons. These could include formulation, surface preparation, application, drying and curing times and conditions, and environmental exposure, with more than one contributing factor often being involved. Failures and defects can manifest themselves at various times in the life of a coating. Prior to application, they can take the form of settlement and skinning, during application as runs and sags, shortly after application as solvent popping and orange peel, and during service as blistering and rust spotting. This guide will explain each defect/failure, showing examples that will help you the contractor/inspector evaluate your coating to the root cause of the problem.
