Basic Application Guide

For more information on applying Jotun Pioner topcoat please see our detailed application guide here

Step 1 - Surface Preparation

• Pioner topcoat can be applied over a range of primers or existing Pioner coats.
• Ensure surfaces are clean, dry, and free from contaminants.

Step 2 - Primer Application

• Apply a compatible primer such as Jotun Vinyguard, Pilot QD Primer, or 2-pack products from the Jotamastic and Penguard ranges.  Pioner should be aplied within 24 hours of after 7 days.

Step 3 – Mixing and thinning

• As a single-component product, Jotun Pioner Topcoat requires thorough stirring before application.
• In hot or windy conditions, you may also want to consider adding up to 10% thinners to compensate for increased evaporation.  Jotun Thinner No.7 should be used

Step 4: Application Conditions and Methods

• Temperature - Apply when ambient and surface temperatures are between 10°C and 30°C.
• Humidity - Ensure relative humidity is below 85% to promote proper curing.
• Brush - Suitable for small areas and touch-ups.
• A roller can be used
• High-Pressure Airless Spray - Recommended for large areas

Step 5 - Drying and Recoating

• Surface Dry - Approximately 2 hours at 23°C.
• Number of coats will depend on application method.  We recommend that 2 coats are applied if using a brush or roller
• Minimum Recoat Interval – Provided the surface is clean & dry there is no time limit between coats.

Step 6 - Cleanup

Clean tools and equipment immediately after use with Jotun Thinner No. 7 or SML Xylene Thinner.

The FAQ's below are for general guidance only.  For specific questions, please refer to the application guides and data sheets on our product pages or give us call and we will answer any questions that you have.

Q. What substrates can Jotun Pioner Topcoat be applied to?
A. Jotun Pioner Topcoat is suitable for steel, aluminium, and previously painted surfaces. It provides excellent adhesion when applied over a compatible primer and offers durable protection in commercial marine, industrial, and general maintenance applications.

Q. Is a primer necessary before applying Jotun Pioner Topcoat?
A. Yes, using a compatible primer such as Jotun Vinyguard, Pilot QD Primer(apply Pioner within 24 hours or after 7 days), a Jotamastic or Penguard product is recommended. This will ensure better adhesion, corrosion protection, and overall longevity of the topcoat.

Q. How long does Jotun Pioner Topcoat take to dry?
A. At 23°C, the coating becomes surface dry in approximately 2 hours. Drying times may vary depending on temperature, humidity, and ventilation. Recoating times depend on ambient conditions and should be checked in the technical data sheet.

Q. Can Jotun Pioner Topcoat be applied over existing paint?
A. Yes, it can be applied over existing, well-adhered, well weathered coatings after proper surface preparation, such as cleaning and light sanding, to ensure good adhesion. However, compatibility with existing coatings should always be tested first.

Q. What application methods are suitable for Jotun Pioner Topcoat?
A. It can be applied using brush, roller, or airless spray. Airless spray is recommended for larger  areas,

Q. How should the surface be prepared before application?
A. Surfaces should be clean, dry, and free from oil, grease, rust, and loose coatings

Q. Is thinning required for Jotun Pioner Topcoat?
A. Thinning is not usually necessary.  However, when applying with brush or roller in hot or windy conditions, some thinning with Jotun Thinners No. 7 or SML Xylene Thinner may improve the useability

Q. What is the coverage rate of Jotun Pioner Topcoat?
A. The natural spreading rate when applied by brush or roller is approximately 10 m² per litre. Actual coverage will vary according to application method and surface roughness.

Q. Can Jotun Pioner Topcoat be used in marine environments?
A. Yes, it is suitable for marine applications, particularly on topsides, decks, and superstructures. However, for continually immesed below-the-waterline applications, a dedicated antifouling or epoxy system should be used instead.

Q. How should tools and equipment be cleaned after use?
A. Tools and spray equipment should be cleaned immediately after application using Jotun Thinner No. 7 or SML Xylene Thinner.

Q. How durable is Jotun Pioner Topcoat in harsh environments?

Q. How long should I wait before exposing the coating to full service conditions?
A. Jotun Pioner Topcoat reaches full cure in approximately 24 hours at 23°C

Q. Is Jotun Pioner Topcoat resistant to UV exposure?
A. Yes, it has good UV resistance, making it suitable for exterior applications where exposure to sunlight and weathering is expected. However, polyurethane coatings offer even better gloss and colour retention in extreme UV conditions.

Q.  Are there any limitations to Pioner Topcoat?

A.  Pioner Topcoat is best suited to a commercial environment.  It is ideal for use on workboats and other commercial vessels, when touch-up or repainting with a minimum of preparation is required as it bonds to itself without requiring a “key”.  It has thermoplastic properties and softens at temperatures over 35˚C.  We do not recommend it for leisure use.
