It is normal for steel structures to come into contact with moisture, air, salt spray, temperature fluctuations and industrial pollution on a daily basis. This can lead to corrosion of the steel surface and subsequently weaken the surface, shorten the service life, increase maintenance costs and may even pose a safety risk. Choosing the right anti rust paint is not simply a matter of selecting a product that will stop the metal from rusting. When choosing a coating contractors need to consider a number of factors such as surface preparation, application, properties of coating, drying time, site conditions and suppliers. KONAZ Anti Rust Paint is a metal coating, specifically designed to offer excellent adhesion to metal surfaces and to provide protection against corrosion as well as resistance to moisture, salt spray and oxidation. This article highlights the main points that contractors should take into account before coating steel and how to select an appropriate coating for a variety of applications.
Why Do Steel Structures Need Anti Rust Paint?
Steel is a strong metal and is one of the most commonly used building materials, for example in buildings, factories, bridges, workshops, warehouses, pipelines and other outdoor equipment. Unprotected steel that is exposed to the weather can, however, corrode as it reacts with water, oxygen and other aggressive environments.
Corrosion Can Reduce Structural Service Life
Rust is more than just a cosmetic issue. As the surface of the steel corrodes it can form a layer which can reduce the performance and reliability of the component. As well as normal aging in the atmosphere, rust can form much faster in industrial or coastal locations where it is exposed to moisture and salt. The oxidation process is speeded up in these situations.
For contractors, that could translate into an earlier than anticipated requirement for repainting, repair, or even full replacement of items. It could also translate into additional project complaints.
Protective Coatings Help Control Maintenance Costs
Anti rust paint forms a protective film on the surface of the steel. This film, or coating, helps to prevent moisture and other corrosive substances from coming into contact with the steel, potentially reducing the need for future repairs and extending the life of the steel structure.
Steel Projects Need Consistent Coating Performance
Large steel projects often include beams, columns, railings, frames, ladders, platforms, pipes, tanks, and outdoor components. Contractors need a coating that can be applied consistently across different parts while maintaining adhesion and protection.
What Should Contractors Check Before Applying Anti Rust Paint?
Make an assessment of the surface to be painted, the environment that the paint will be in and the project details before you even open the paint drum. The key to painting is preparation to achieve a durable finish or risk peeling or rust returning early.
Surface Cleanliness
Before painting the steel surface must be clean. If the surface is contaminated with oil, grease, dust, loose rust, weld spatter or old peeling paint then adhesion will be poor even with a good anti rust paint.
Contractors should clean the surface according to project requirements. Depending on the steel condition, this may include degreasing, sanding, grinding, wire brushing, or blasting.
Rust Level
Steel surfaces can differ quite significantly, including new steel, steel with light surface rust and steel that has already been subjected to considerable corrosion. This means that certain surfaces can be coated after simple mechanical cleaning, but others require far greater attention and care prior to coating in order to ensure adequate adhesion of the selected coating.
Painting over loose rust can be problematic. Initially the surface may look to have been painted ok but as the rust continues to expand the paint film will delaminate from the surface.
Dry Surface Condition
Steel should be dry before painting. Paint that is applied over moisture will blister, peel or cause the steel to rust. Paint should not be applied during rain, heavy fog or any situation where there is condensation.
How Should Contractors Choose the Right Anti Rust Paint?
The correct anti rust paint will depend upon the working environment, substrate, method of application and the required lifespan of the coating. Contractors must judge between the paint’s performance and its use on site.
Adhesion to Metal Substrates
One of the most important characteristics of anti rust paint is its adhesion. KONAZ Anti Rust Paint has a strong adhesion of paint film for metal substrates. It does not peel off if surface is prepared well.
Adhesion is of particular importance for steel structures at edges, welds, bolt contact, corners and highly loaded contact surfaces.
Resistance to Moisture, Salt Spray, and Oxidation
Many outdoor steel structures are exposed to rain, humidity and pollution. Coatings in coastal or marine environments may even be exposed to salt spray, which can increase the risk of corrosion even more. In order to counter corrosion and rust, a coating must be able to provide sufficient anti-corrosion and anti-rust protection.
KONAZ Anti Rust Paint is a protective paint which protects against moisture, salt spray and oxidation. This paint is particularly suitable for steel structures, pipelines, boats, machines and other metal parts that are exposed to the open air.
Application Flexibility
Depending on the area to be treated on a construction site, different application methods are preferred. For larger steel parts an overspray free coating can be applied by spraying. Smaller repair works are best carried out with a brush or roller.
A coating that can be applied with spray, brush or roller is far more flexible during new construction, repair and maintenance work.
Which Technical Details Should Be Checked Before Painting?
The technical data for our anti rust paints helps contractors to give a better estimate for the required quantities for the materials for the work to be carried out as well as for the planning of the work so as to avoid mistakes when applying the paint. Before ordering the paint, the buyer should check the coverage, the drying time, the color, the finish, the packaging as well as the storage.
Coverage and Material Calculation
KONAZ Anti Rust Paint has a theoretical coverage of 6–8㎡/kg per coat. It is possible to calculate the consumption for a project on the basis of this data, but the actual amount needed will also depend on other factors such as the roughness of the surface, the method of application, the thickness of the coating, and the amount of waste on site.
For large steel constructions it is advisable to calculate with a certain safety reserve as opposed to the theoretical coverage rate.
Drying Time and Work Schedule
Drying time affects the planning of your project. After applying KONAZ Anti Rust Paint it will be touch dry after 2 hours and hard dry after 24 hours at 25℃. This enables you to plan your recoating, handling, transport and installation work accordingly.
Real drying time may vary from information given in this chart due to effects of temperature, humidity, ventilation, film thickness, and site conditions.
Color and Finish Options
KONAZ Anti Rust Paint is offered in Grey, Red Oxide and any other color that you require. KONAZ Anti Rust Paint can be supplied with a Matte or Semi-Gloss finish. Please advise if the paint is to be a visible topcoat, a hidden primer or if to be used as part of a multi coat system.
For steel structures, Red Oxide and Grey are two of the most common colours. These colours are very practical as they can withstand in an industrial and construction environment.
