SURFACE PREP SIMPLIFIED
The Preparation Group demystifies some of the common queries their technical team receives on surface preparation, equipment and the hiring/buying process.
Here at The Preparation Group, you may be surprised to know that 35% of our incoming calls are purely for technical advice across our range of products and services. Enquiries range from: ‘how do I polish concrete?’ to ‘which nut and bolt is needed to attach my cup discs to my drive plate?’ and even ‘I have 2500m² of concrete to prep in readiness for a resin floor, can you help?’. The huge amount of technical knowledge gained in the 30 years we have been trading is paramount to the excellent customer service we deliver and enables us to provide the answers to all these questions and many more.
Through continuous Research and Development, we are continually providing new equipment that is robust and designed to effectively withstand the rigours of mechanical surface preparation. Ideally placed to design and manufacture equipment through experience and use within our contracting department and training school, we manufacture some of our ranges here in the UK. Having just gained Made in Britain accreditation for these ranges we are proud to be able to offer quality British-made machines helping to revive the UK economy in these strange times.
Did you know that mechanical surface preparation is a prerequisite to obtaining a full warranty on newly laid floors? The wording in most small print warranties state that the area must be mechanically abraded before any application is laid. Another word that is often used is blastracking. The main areas of mechanical surface preparation are; laitance removal, adhesive/bitumen removal and coating/paint removal. It is important to understand that getting it wrong can be costly and selecting the correct methods at the outset is imperative.
The key here is understanding what is required and what the words may mean. For example, the word blastracking is not a process and purely refers to a brand, a bit like saying you are going to hoover up. The correct terminology, which should be used, is shotblasting.
WHAT IS SHOTBLASTING? All shot blasting machines work on the same principle of shot
36 | MACHINERY, TOOLS & ACCESSORIES
steel abrasive being propelled inside the machine at a high velocity onto the background surface to clean and create a profile/key or remove surface coverings and contaminants. Our machines are environmentally friendly and have a greater tip speed than other machines for maximum production. All feature even weight distribution for ease of operation and uniform blast pattern. And, they come with simple electronics, heavy duty bearings, hydraulic cooling system, high quality motors, and the wear parts are simple designs for quick changing to you keep working for longer. Our shot blasters are made from a high-grade manganese steel exterior as are their compatible filtration systems, fitted with hydravane technology for maximum suction and large high particle containment.
PREPARATION VIA
MECHANICAL ABRASION This wording incorporates many different types of surface preparation equipment which we have included in our Surface Preparation Method Guide. Broken down into easy-to-read elements it shows the type of coatings that may require removal and indicates what type of machine we supply to do the job along with the appropriate tooling/consumables.
We can provide a simple chart which allows at an easy glance to determine what solutions there are for your surface preparation requirements. This is a guide which can also help you to understand and demystify the equipment hiring/buying process not only for machines, dust extraction but the required consumables for the appropriate machines.
On our website, we have produced a fantastic jargon buster which covers all types of surface preparation, the equipment used and the different types of tooling and consumables required for each individual job.
