Sustainable concrete repair products can extend the time in between repair cycles and increase the service life of a structure. This will discuss the fact that based on 10+ years of field and laboratory testing, organofunctional silane corrosion inhibitors are effective at corrosion mitigation, thus decreasing the frequency and extent of repairs. Evaluation on new concrete also showed a predicted increase in time to corrosion initiation when compared to untreated reinforced concrete specimens. Modeling results were verified in a 2-year laboratory study.

This presentation will outline the results and conclusions of a number of years of testing and experience in surface preparation for high-performance coatings. Testing has shown that there are a number of important surface preparation variables that are not routinely monitored and controlled on coating projects. These variables will be identified and guidance will be provided on appropriate treatment to achieve coating results.
The use of climate control is commonly perceived as an additional cost and the energy consumed is often substantial. A closer look at the real impact can uncover economic and environmental benefits that may offset and even exceed the initial costs. These benefits include life cycle costs of the coating system, efficiencies in the project sequencing and minimizing coating and solvent waste
The paper is an overview of the National Shipbuilding Research Program (NSRP) Surface Preparation and Coating Panel’s (SP&C) mission to reduce the cost of construction, maintenance, and repair of US Navy ships. The Panel’s “Specs to Decks” approach; research, evaluate, develop, and sustain current and emerging technologies that will reduce cost and maintain or enhance quality, serves as a rudder that guides the Panel’s performance. This review will provide a summary of the Panel and a look at some of its implemented, current, and proposed projects.
This paper introduces a novel method for chemical surface preparation of concrete surfaces that has been recognized by ASTM under a recent revision of ASTM D4260. Contractors will learn current methods used to prepare concrete in order to receive coatings. The objectives of the presentation are: to understand the current methods for surface preparation of concrete, to identify the current standard for chemically etching concrete and the new materials that have been developed that meet the revised standard, and to present the environmental advantages of the new product in a real world project example.
It is well understood that unless a surface is properly prepared prior to the application of a coating or surface treatment, adhesion and the expected lifetime of the material is quite minimal. Preparation generally falls under one of two options: either utilization of particle or grit-blasting, or the use of waterjetting. Typically, waterjetting of surfaces in preparation for application of coatings or surface treatments is only conducted on metal substrates that contain a previous profile from either operational wear (corrosion pitting) or previously abrasive blasted surfaces.
The intent of this presentation will be to briefly analyze the evolution of the steel surface preparation market by focusing on three common methods for steel surface preparation used today (i.e., dry abrasive blasting, wet abrasive blasting and ultra-high-pressure blasting (UHP)) and the effects of water and additives on cleanliness, degree of surface preparation, coating integrity and coating adhesion. This presentation will include test results comparing the effects and results of different forms of surface preparation and the resulting coating application characteristics.
Zinc rich primer coatings, both organic and inorganic, are extensively used in highly corrosive environments and they are part of a high performance coating system in the Protective Coatings Industry. During the 60’s and the 70’s, zinc rich epoxy primers dominated the market. Later, zinc ethyl silicate primers took over mainly due to their higher potential to corrosion protection. Nowadays however, new developments in zinc epoxy primers are setting the two categories of Zinc rich primers on the same level in terms of anticorrosion performance while adding the advantages of Epoxy based primers.
Concrete will crack – that is a fact. When cracks appear, they are dynamic or static, and structural or non-structural. If the crack is static, non-structural, and does not leak, epoxies are great to restore design strength. However, since concrete constantly shrinks, expands, and often leaks, the use of a flexible polyurethane resin to permanently seal active leaks is the optimum choice to create a leak-free environment.
The objective of surface preparation is to create proper adhesion of a coating over the substrate. Proper surface preparation is vital to the long life and effectiveness of a coating applied in corrosive service. In some projects, the owners ask for the additional water jet cleaning prior to blasting work.
