At Chiltern Blast Cleaning, we can provide a number of wet spray coatings and finishes, to both Trade and Domestic customers. With over 30 years experience in preparation and coatings, we have worked with most types of paint, applying a range of different products and paint systems to most surfaces in that time. We use both conventional air spraying, as well as airless, dependent on the paint/finish required
We are also approved applicators for Cromadex/Interpon & Zinga, amongst others.
Wet Spray Painting
What is wet spray painting and the process?
Wet spray painting is the process of applying a liquid coating to a substrate, using equipment that allows the user to spray the paint evenly over a surface.
In conventional spraying, this is done using compressed air. The paint is fed to a spray gun, where it 'meets' the compressed air to atomize the paint stream into tiny droplets, sprayed onto the surface it is sprayed towards.
Airless spraying uses a pump system, to deliver the paint to the gun at extremely high pressure, forcing it through a small hole. The tip & nozzle create a fan pattern of the stream of paint, as it exits the gun, to allow an even distribution of the paint onto the surface
There are advantages to both of these methods, that allow for different applications, but generally speaking, they both allow the user to apply a thin, uniform and professional finish, to the substrate. As with any painting process, the key to a high quality finish is in the preparation.
Wet spray painting is probably most commonly associated with automotive finishing/refinishing, and while this is one its primary and most functional applications, it is not the only time, or industry that it is relevant to.
It has a really important place in the work that we do, and we use several different wet paint products for our customers. This can be for protective and functional purposes, as well as the usual aesthetic finishing.
What are the benefits?
-
Wet spray painting is particularly useful for large, heavy or awkwardly shaped objects that cannot be hung for powder coating.
-
Where a professional, aesthetic finish is required
-
It is a cost-effective finish, significantly more economical than some alternatives – particularly for low production runs.
-
Colour selection is almost infinite, providing the opportunity to match branding or aesthetic requirements.
-
It can be applied to a range of materials and is ideally suited to heat-sensitive parts that cannot be powder coated.
-
The paint applied is a much thinner coating than other processes, which may benefit lightweight or precision parts.
-
Wet spray painting allows you to air-dry your product for finishing - ideal for hydraulic or engine powered items
-
Specific protective or functional coatings that have to be applied via solvent based products
What can you apply it to?/what work do we do it on
Primers for blasted steel
Once a metal substrate has been cleaned of all old paint & rust etc, the bare metal is then exposed to moisture and other contaminants. Particularly in the case of restoration work, time is often needed for other work and repairs to be carried out, so the bare metal needs to have protection from rust and corrosion that it is exposed to, even if only left for a couple of weeks.
We use a few different zinc based/ zinc phosphate primers, that can be used as ‘holding’ primers and are generally effective for 6-12 months while any work that is required can be carried out. They are semi-weldable, and can be used as a base for further coatings as projects progress, so are perfect for this purpose
Classic car bodyshell restoration
As we do a lot of work with restoration companies on car bodyshells, we can also offer primers specifically developed for this purpose, such as Mipa and Novol bodywork primer. They are water based products, that are fully workable, weldable and compatible with further coatings, used within automotive finishing & restoration
Kitchen units & furniture refinishing
2 pack primers and topcoats that are designed & formulated to provide a high quality and durable finish on a number of different materials - including wood, MDF & PVC as well as metal. Once prepped, the product is given 1 or 2 coats of primer to provide a base and build for smooth finish in topcoat. The final coat, in customers choice of colour, is then applied.
Plant and machinery painting & refurbishment
Material handling equipment such as trailer bodies, dumpers and diggers can be blast cleaned, and then repainted using anti corrosive primers, and 2pk acrylic topcoats designed for commercial/industrial uses.
Specialist paint coatings
Wet spray painting is also great for when specialist products need to be applied, as they often cannot be applied through other processes like powder coating due to the fact that they require a solvent base, in order to carry the chemical properties.They contain specific chemicals which provide important characteristics , such as high zinc content primers for protection from corrosion, intumescent / fireproof and high temperature resistant coaings.
