Application
Before starting, have your PPE ready, as our paint is oil-based and will not wash off easily with soap and water.
Ensure you have good ventilation to allow vapour to escape; ventilation is also necessary to maintain drying times. Without air movement, the coating won’t dry properly.
Be sure to stir the paint well before use.
Painting Bare Metal:
Step 1 - Prep: Ensure the substrate is completely dry and free of any dirt, oil, or grease by using a degreaser.
Step 2 - Prime: Apply one coat of this primer.
Step 3 - Topcoat: Once the previous steps are complete, apply your first coat of top coat within 12-24 hours. Wait another 12-24 hours before applying the second coat.
Painting Over Existing Paint:
Step 1 - Preparation: Check the suitability of the product for the existing paint. We recommend trying a sample area first.
Step 2 - Clean and Abrade:
- Ensure the existing paint is in good condition prior to painting, then lightly abrade to provide a key for good intercoat adhesion.
- If there is flaking paint, it must be removed before painting.
- Ensure the substrate is dry and clean of any dirt, oil or grease.
Step 3 - Prime: Apply one coat of this primer.
Step 4 - Topcoat: Once you have completed the previous steps, 12-24 hours after applying the primer, you can add your first coat of topcoat. Wait another 12-24 hours before applying the second coat.
Painting bare Wood:
Step 1 - Clean and Prep: Ensure the substrate is dry and clean of any dirt, oil or grease. If there is any moisture in the wood, it can cause delamination and lead to a loss of adhesion.
Step 2 -First Coat: Apply one coat of this undercoat.
Step 3 - Top coat: 12-24 hours after applying the first coat, you can apply the first coat of your top coat.
Two coats of topcoat are recommended for optimal coverage.
Mixing
Always stir any paint well before use, as our coatings are heavily pigmented and separation can easily occur. You may experience colour float; for example, a green paint can appear blue before mixing. This is one of the reasons why mixing your paint before use is essential.
- Use a mixer on a slow-running drill or a palette knife on smaller cans to mix the paint. An egg whisk, screwdriver, or small stick that doesn’t reach the bottom of the can is insufficient for proper mixing.
- Mixing should take place for 3-5 minutes.
- If you are adding thinners; they will need to be added once stirred.

Spraying
Ensure you have the correct RPE, to protect against atomised particles that are being generated when spraying.
If applying with a pot gun:
Use a 1:8 to 2:0 tip setup and thin by 10% if required. More thinners may be added to achieve good atomisation and improve the flow of the paint, resulting in a better finish.
Air-assisted or Airless system:
Use an 11-13 thou tip (no thinners are usually required). If thinning is necessary, use around 10%. Set air and paint pressures until good atomisation is achieved and fingering (lines in the spray) have blended in.
