Paints & Coatings Application Guides

Surface preparation ensures the coating can properly bond to the substrate. Whether working on wood, metal, masonry or previously coated surfaces, contaminants, weak material and smooth finishes must be addressed before application. Without proper preparation, coatings will fail regardless of product quality.

Yes. Wood may require sanding and knot treatment, metal requires rust removal and degreasing, while masonry often needs cleaning and stabilisation. Each substrate behaves differently and requires a tailored preparation method.

Only if the existing coating is sound and properly prepared. Loose or failing material must be removed, and glossy surfaces must be keyed to ensure adhesion.

Yes. Dirt, grease, dust and environmental contaminants can prevent coatings from bonding properly and must be removed before application.

Poor preparation is the leading cause of coating failure, resulting in peeling, flaking, poor coverage and reduced durability.

Not always, but primers are recommended in most cases to improve adhesion, regulate absorption and provide a stable base for topcoats.

Primers prepare the surface for coating by improving adhesion, sealing porous substrates and ensuring a consistent base for finishing coats.

Skipping primer can lead to uneven coverage, poor adhesion and reduced durability, particularly on porous or difficult substrates.

Most systems require a primer followed by one or more topcoats. The exact number depends on the product and application.

Yes. Correct layering ensures the coating performs as intended, providing durability, protection and finish quality.

Selection depends on substrate type, exposure conditions and required performance. For example, exterior surfaces require weather resistance, while metal surfaces require corrosion protection.

Not always. Different substrates require coatings designed for their specific properties, such as flexibility, breathability or corrosion resistance.

Incorrect product selection can lead to poor adhesion, premature failure or inadequate protection.

No. Some coatings are not compatible with existing systems, which can lead to adhesion failure or reaction between layers.

Check product specifications and ensure the system is suitable for both the substrate and any existing coatings.

This depends on the product and surface. Brushes, rollers and spray systems may all be used depending on the application.

Apply coatings evenly, maintain correct coverage rates and use appropriate tools. Consistent technique is essential.

No. Over-application can lead to poor curing, surface defects and reduced performance.

Yes. Multiple coats build up the required film thickness and improve durability.

Incorrect application, poor preparation or unsuitable conditions can all affect the final result.

Drying times vary depending on product type, temperature and humidity. Always follow product-specific guidance.

Temperature, humidity and airflow all influence drying and curing. Poor conditions can lead to defects or reduced durability.

Some systems are designed for these conditions, but many require minimum temperatures and dry substrates.

Initial drying allows light use, but full curing is required before exposing the surface to heavy use or stress.

Incorrect conditions can cause slow curing, poor finish, adhesion issues and reduced coating lifespan.
