Our customers recognise that no matter how good SELEMIX® paint is or how well they apply it, failure to properly prepare their surfaces before the painting process starts will most likely result in sub-optimal performance.
A coating is only as good as the preparation of the underlying surface.
Indeed poor initial surface preparation has been estimated to account for up to 80% of subsequent paint problems.
One of the most common methods used to prepare surfaces for painting is Abrasive Blast Cleaning. This method involves propelling abrasives at high speed towards the surface to be cleaned.
Blast cleaning readily removes oxides formed at high temperatures (mill scale) and those formed at room temperature by corrosion (rust). It can also remove soldering, welding or foundry residues and is an excellent way of providing an anchor pattern on the substrate to support better coating adhesion.
It is an extremely effective way of preparing a surface, but we’ve also seen it cause problems if done incorrectly.
With the benefit of many years experience in supporting our Selemix customers, we thought it may be helpful to provide some tips to get the best out of Abrasive Blast Cleaning:
The key to getting the perfect Selemix finish is to ensure that the surface to be painted is thoroughly prepared. This is never more true than when using abrasive blast cleaning. We hope the above tips will help you ensure you get the best out of our products.
