Surface preparation not only cleans away undesirable contaminants like mill scale or grease, but also introduces a suitable profile for the coating.
How to use water in a blaster?
The conventional method is to use the same pressure as with dry blasting with the addition of the water being introduced behind the nozzle so that it is atomised and accelerates through the nozzle alongside the air and abrasive substance. Alternatively, the water can be added in controlled amounts at the base of the blast pot before mixing with the air and abrasive as they pass along the blast hose. A lower pressure system is also available whereby the water is injected into the air stream. The water then shrouds the abrasive/air mixture to prevent dust from escaping from the stream. However, the low pressures mean that fine abrasive particulates can remain on the surface and will need to be washed away. In some instances, inhibitors are used as part of the wet abrasive process to prevent the cleaned surface from rusting. In these instances it is worth checking that any leftover traces of the inhibitors will be compatible with any coating that is to be applied after. Alternatively, light dry blasting can remove any surface rusting following wet abrasive cleaning. It should be noted that the substrate must be dry prior to coating.
Why do coatings have pinholes?
Wet surfaces can cause pinholes to develop during the curing process as moisture evaporates from between the surface and the coating, forming small holes. Although some coatings use a second layer to cover these pinholes, moisture can also negatively impact drying times.
What is a jet of particles used for?
This method of cleaning uses an abrasive jet of particles in a compressed air stream which impacts on the surface, removing impurities, mill scale, old paint and rust. Widely used in shipbuilding and repair , it is particularly effective in removing oxide corrosion. It is also widely used in the aerospace and medical sectors prior to the application of thermal sprayed coatings, and many other industries.

It is important to clean surfaces just before painting as they can accumulate dust, concreting grout leaks, blast cleaning products, or the products of bolting and welding.
How to clean a surface with solvents?
The simplest form of solvent cleaning is to use soap and water with a rag to wipe the surface down. However, this is also the least effective as the rag can end up just smearing the substance across the workpiece. Soap can also inhibit coating adhesion and other processes, so needs to be thoroughly washed off.

How to dry abrading paper?
When dry abrading, don’t push down on the paper. Apply a light touch and let the paper do the work. For a more consistent surface, don’t just sand in one direction, use an even, circular motion to give the adhesive a good surface to “key” into. When wet abrading, apply a little bit of pressure and short strokes.

Do you need a clean surface?
Cleaning. Of course, you need a clean surface. If you’ve got a layer of dirt on both surfaces, all you’re doing is sticking dirt to dirt. The main task at hand is just removing any dust, grease or mould, so anything that gets the job done is fine. Know your surfaces and how to clean them.
Can you wet an adhesive?
In order for an adhesive to effectively bond to a substrate, it must be able to “wet” the surface. Some surface treatments affect the surface energy. In non-technical terms it is the difference between water on a freshly waxed car which beads up and rolls off or water on an old unwaxed car that wets the entire car.
What is inadequate surface preparation?
Inadequate surface preparation results into majority of paint failures. Surface preparation techniques vary according to the type of surfaces. Interior and exterior surfaces even cannot follow the same procedure. Similarly, it would vary considering its fresh painting or repainting.

Paint Adhesion
When it comes to surface prep, using an eye test won’t cut it. Though your surface may appear to be clean, very small traces of dust, dirt, and mold can hinder the paint from properly adhering to the surface. This can cause paint to chip, peel, flake, and rub off. This causes an assortment of problems.
Even painting
Part of surface prepping is laying down a base of primer properly. Without a proper base of primer, your painting could end up looking uneven. A good coat of primer helps the paint absorb more evenly across the entire wall.
Durability
To extend the longevity of your paint job, surface prep is crucial. Damp walls, dirt, and cracks can shorten the life of your paint job, even if the quality of the pain you are using is good.
Remove Old Paint
It is important to remove the old paint. Especially if this paint is flaking, chipping, or rubbing off. Old paint can easily accumulate dust, dirt, grime, mold, and other hindrances to a new paint job. In some cases, old paint can contain lead or asbestos.
Quality Paint
This one is important. It may be tempting to use cheaper paint, but with cheap paint, you get what you pay for. You may wind up having to sink more time or money into repainting much sooner than if you use quality paint.

Identifying Imperfections
Bond Failure at The Substrate
- Bond failure at the substrate occurs when the coating or flooring system delaminates at the bond line, which leads to the finish being easily removable from the substrate. This can be identified through peels, chips or separation in the floor coatings. These chips or cracks can be a trip hazard, as well as being epicentres for dirt, dust and bacteria. Causes of this failure could be du…
Preventing Bond Failure
- The foundation of any coating or flooring system is surface preparation. The purpose of surface preparation is to create a surface profile that will promote mechanical adhesion by removing all contaminants.
