Protective Coatings FAQs Answered
DO YOU HAVE REFERENCES?

WHAT KIND OF PAINT OR COATINGS DO YOU USE?
We use coatings supplied by world leaders like Jotun Paints, PPG, Sigma Coatings and Technical Services most of the time. Sometimes customer preference, the nature of the job and other factors warrant other brands. Whichever brand we use, we make certain it’s the best that manufacturer offers and appropriate for your project.
ARE YOU SUPPLIERS OF PROTECTIVE COATINGS OR ARE YOU PAINTERS / APPLICATORS OF COATINGS?
We offer a comprehensive range of coatings in the Western Cape Industrial Coatings market. We are Applicators of Coatings and supply the coatings. Specifications are graded on a site specific basis taking in consideration the site location, environmental and exposure conditions, and strict adherence to supplier application directives.
WHAT WE DO TO PREPARE BEFORE APPLYING ANY COATINGS?
Substrate preparation is critical to the long term performance of coatings. The floor, wall, steel structure and any other surfaces must be clean of all contaminants, including paint, dirt, dust, loose debris, oils and sealers. Preparation is done in accordance with coatings suppliers directives. We always apply a sample of the material to the substrate to determine coverage rate and adhesion. Even brand new floors have contaminants, such as oil and dirt that must be removed prior to flooring installation.
WHY DOES ONE NEED TO USE A PRIMER?
Primers are specially formulated coatings that perform several functions.
- A quality primer has the ability to bond topcoats to different substrates, seal substrates, promote adhesion and protect topcoats from flaws.
- Primers help the topcoat to adhere to the substrate being painted. They do this by making the surface more uniform and accepting for the topcoat, so that when the paint is applied, it can get a better “grip” than it would on a bare surface.
- Primers give a topcoat a more uniform appearance in terms of colour and sheen, thereby making it more attractive. This is especially true when the surface being painted is porous/uneven.
- Primers also protect the substrate (especially ferrous surfaces) from corrosion. These primers contain special pigments e.g. zinc phosphate which prevents the surface from rusting.
DO YOU GIVE ADVICE FOR HOUSE PAINTING COLOUR SELECTION?
Yes, we give expert advice on what colours to choose. You also have the option to test sample house painting colours on your walls before making your final decision.

WHERE CAN WE FIND REPUTABLE APPLICATORS OF PROTECTIVE COATINGS?
We are approved applicators for our coatings. With our wide range of experience we can develop a solution for your unique operational environments.
HOW MANY COATS OF PAINT SHOULD BE APPLIED?
It depends on the circumstances and the paint we are using. We believe in strict adherence to supplier application directives.
HOW UV RESISTANT IS FLOOR PAINT?
Epoxy paints are not ultraviolet resistant and will “chalk” when exposed to UV light for a period of time. Chalking is a white powdery residue that comes to the surface of the paint. It is cosmetic only and will not affect the performance of the paint. This being one of the main reasons why epoxy primers are over coated with a topcoat, resulting in a better cosmetic appearance. Two pack polyurethanes are the most UV resistant and will retain their gloss and colour for at least twice as long as the best single pack topcoats.
WHAT IS THE COVERAGE OF PROTECTIVE PAINT IN SQUARE METRES PER LITRE?
This depends both on the type of paint and the method of application. Using a brush or roller, coverage will be around 8m² per litre per coat for the primers and 10m² per litre for the topcoats. The thicker the paint is, the more you will be able to pick up with a brush or roller, which will reduce the coverage. With thinner paints, you will pick up less and the coverage will be more.
CAN PROTECTIVE COATINGS BE SPRAYED?
Yes, with Primers, only use a high pressure airless spray as the paint is too thick for a conventional air spray. Airless spray is the best method of application as it is possible to lay down high film thicknesses at a minimum of coats. In the case of Topcoats, you can achieve very good results using a conventional air spray. For high quality work, air spray is preferable to airless spray as the spray mist is finer resulting in a smoother finish. Important, in cold weather it may be necessary to thin the paint by 5-10%.
HOW LONG WILL THE PAINT TAKE TO DRY?
This depends on the type of paint and the surrounding temperature. Refer to the data sheet for the particular paint you are using. This gives details on drying times at various temperatures. This also gives details on minimum over coating times at various temperatures – how long you have to wait before applying a second coat.
