SURFACE PREPARATION FOR PROTECTIVE COATINGS


Three


approaches to surface preparation Different


techniques for the cleaning and preparation of industrial surfaces.


Surface preparation is the process of treating surfaces chemically or mechanically prior to the application of coatings to ensure further treatments are successfully applied. Techniques can be used to smooth a rough surface, roughen a smooth surface or to remove coatings and contaminants depending on the methods and abrasives used.


SURFACE PREPARATION TOOLS A huge range of tools are available for surface preparation, from hand-held tools to heavy-duty floor machines, pneumatic to electric. Trelawny SPT Ltd is an independent manufacturer of pneumatic tools and surface preparation equipment designed for the removal of deck coatings, paints, corrosion and rust from steel structures such as offshore platforms, bridges, large ships & vessels.


The company has supplied their ever evolving product range into the global offshore industry for many years now and in recent times, under its designated trade mark Vibro-Lo, have become a market leader in reducing vibration across this type of equipment reducing vibration related injuries. Innovations such as their tool and vacuum system (TVS) for the containment of paint, rust and debris has proved successful in recent years as well as providing additional operator options such as cold-spark cutting media, fall arrester brackets, whip check safety hoses and the new development of their ATEX rated needle scaler range.


Many of these tools, especially heavy duty scabblers, can be used as a pre- preparation to break down hard coatings before the surfaces are blast cleaned. This combined use of two surface preparation techniques can reduce costs by reducing the amount of expendable blast media used.


BLAST EQUIPMENT


Blasting equipment forms a vital part of the surface preparation industry, providing means to clean and prepare surfaces of almost any size or shape. Blasting typically uses an abrasive material, such as garnet, with a high pressured outlet of fluid or air which is ‘blasted’ directly at the surface to remove contaminants or until the desired surface texture is achieved.


Founded in 1959, Hodge Clemco are recognised as market leaders in this area and have consistently set the benchmark in the manufacture and supply of abrasive blasting and surface treatment equipment. Their product portfolio includes an extensive range of portable abrasive blast machines, hand blast cabinets and blast rooms plus abrasive recovery systems. A recent acquisition means an expanded offering of abrasives, from plastic mediums
