Powder Coating Specialists
We have over 50 years experience in powder coating, offering a 5-7 day turnaround on most projects, with quality checking at every stage of the process. A one-stop-shop for coating, with 100+ BS & RAL Shades in stock available in matt, gloss, satin and textured finishes.
Blast Cleaning Services
At Mastercote we have two blast containers where we use chilled iron or steel grit to blast surfaces clean of scale, rust, old paint and other contaminates. In order for a coating system to work properly in the field it is essential that the surface is properly cleaned, and blasting is the most effective method on most substrates, particularly if the customer is concerned about longevity of the paint finish. Unless specified otherwise by our customers, we always blast clean to the International ISO-8501-1 standard SA 2 ½ − “Very Thorough Blast Cleaning”.
For coated items it is often necessary to use a pyrolysis oven to heat the metal to over 400 degrees prior to blast cleaning. This process causes the paint/powder coating to peel and greatly reduces the time taken to blast the items, thus saving the customer money. It is imperative that customers inform us of anything that might not withstand such temperatures before it arrives with us.

Anti-Corrosion Priming
We made the decision a few years ago to apply an anti-corrosion powder or wet primer to all products likely to either spend time outside or come into contact with contaminants that might affect the lifespan of the coating. Steel products are blast cleaned and are then coated once with an anti-corrosion powder or wet primer before being coated for a second time using the customer’s colour and finish of choice.
Hot Zinc Flame Spraying
Being used increasingly as an easier and cleaner alternative to hot-dipped galvanising, zinc offers excellent corrosion resistance in some of the harshest environments. Unlike galvanising there is no risk of heat distortion, and no need to fettle runs and sharp edges.
Before applying the zinc spray we blast clean the substrate to provide a roughened surface free of any oil or debris that could cause contamination. Molten zinc is then hand sprayed onto the surface of the substrate, generally to around 60-80 microns though thicker coats would be required for offshore work.
Once applied the zinc must be sealed or painted to give additional protection. For gates, railings and other items to be powder coated we always apply an anti-corrosion primer before adding the customer’s required colour coat which gives three layers of excellent corrosion resistance.

Non-Chromate Aluminium Pretreatment
Our six stage aluminium pretreatment system involves immersing the aluminium or alloy in 7.5 metre long baths of a variety of chemicals and rinses and produces an excellent base for coating, ensuring a hard-wearing, corrosion-free surface.
After being dipped in an acid etch cleaner to remove oils or any other contaminants from the surface, the aluminium is placed in three separate rinse tanks (two towns, one demineralised) before being immersed in the conversion coating. This forms a bond with the clean, etched aluminium and once it has been through a final demineralised rinse and dried in an oven it is ready to be coated, subject to the necessary QC checks.

Powder Coating
We only use the very best architectural grade powders and have 100s of colours in various gloss levels in stock. We have two on-line coating plants that can handle material up to 7.5 metres in length, and two box ovens that cater for wider, taller or heavier items.
Powder coatings are applied by a process called electrostatic spray deposition. The application method uses a spray gun which applies an electrostatic charge to the powder particles which are then attracted to the (grounded) metal substrate. After application the parts enter a curing oven where, with the addition of heat up to 200 Celsius, the coating chemically reacts − melting and adhering to the substrate. It is imperative that customers inform us of anything that might not withstand such temperatures before it arrives with us.

Wet Painting
We’re specialists in the coating of uPVC windows, doors, fascia’s, guttering and all other goods for the home improvements trade. With manufacturers generally supplying in a very limited choice of colours, and operating with a largely extended lead-time for anything bespoke, we are able to transform them with an almost unlimited choice of colours within 5-7 working days.
Many people are now choosing to keep the inside of their frames white whilst showing a more personalised colour to the outside world. This is something we’re experts at, using a range of high quality paints and masking tapes to give you the finish you desire.
We can also wet paint for the automotive, manufacturing and construction industries, with wheels, frames, tools, gates and railings regularly passing through our spray-bake unit.

Our Services Include:
Blast Cleaning
At Mastercote, we utilise two blast containers equipped with chilled iron or steel grit to thoroughly clean surfaces of scale, rust, old paint, and contaminants. Proper surface preparation is crucial for effective coating systems, particularly for ensuring paint finish longevity in the field. As standard practice, unless otherwise specified by our clients, we adhere to the International ISO-8501-1 standard SA 2 ½ for "Very Thorough Blast Cleaning." Additionally, for coated items, we employ a pyrolysis oven to heat metals above 400 degrees prior to blast cleaning, facilitating paint or powder coating removal and significantly reducing blasting time and cost. We emphasise the importance of customers informing us about any materials that may not withstand such high temperatures before processing.
Anti-Corrosion Priming
A few years ago, we opted to enhance the durability of our products by applying an anti-corrosion powder or wet primer to items expected to be exposed to outdoor elements or contaminants that could impact coating longevity. After blast cleaning steel products, they receive an initial coating of anti-corrosion powder or wet primer before being coated a second time with the customer's chosen colour and finish, ensuring enhanced protection and longevity.
Hot Zinc Flame Spraying
Zinc, increasingly favoured over hot-dipped galvanising for its simplicity and cleanliness, offers superior corrosion resistance, even in harsh environments, without the risk of heat distortion or the need for post-coating adjustments. Prior to zinc spray application, we meticulously blast clean the substrate to ensure a debris-free, roughened surface. Molten zinc is then hand-sprayed onto the substrate, typically reaching 60-80 microns thickness, although thicker coats are necessary for offshore applications. Following application, the zinc requires sealing or painting for additional protection. For items like gates and railings intended for powder coating, we apply an anti-corrosion primer before adding the customer's chosen colour coat, providing three layers of robust corrosion resistance.
Non-Chromate Aluminium Pretreatment
Our comprehensive six-stage aluminium pretreatment process involves immersing the aluminium or alloy in 7.5-meter-long baths of various chemicals and rinses, resulting in an outstanding base for coating and ensuring a durable, corrosion-resistant surface. Following immersion in an acid etch cleaner to eliminate oils and contaminants, the aluminium undergoes three rinse tanks (two towns, one demineralised) before immersion in the conversion coating, which bonds with the clean, etched aluminium. After a final demineralised rinse and drying in an oven, the aluminium is ready for coating, pending necessary quality control checks.
