Description
1k Polyurethane Paint is a high-quality, single-pack polyurethane-based enamel specially formulated for boats, barges, and other marine vessels. Designed for durability and versatility, this boat enamel creates a strong, flexible paint film that resists cracking and peeling while offering excellent chemical resistance.
The advanced polyurethane-modified resin system ensures long-lasting protection, even in harsh marine environments, while the inclusion of premium-quality pigments enhances UV resistance, weathering durability, and color retention, maintaining a vibrant, professional finish over time. Perfect for marine applications, Universal PU Enamel is ideal for protecting and beautifying hulls, decks, and other surfaces exposed to the challenges of water, weather, and wear.
Like any painted surface, this coating can become slippery when wet; however, we offer a non-slip version for enhanced safety.
About This Item
- HIGH PERFORMANCE: High coverage with excellent UV resistance and weathering durability, ideal for marine applications.
- AVAILABLE FINISHES: Gloss, Semi-gloss, and Matt. The Semi-gloss and Matt finishes have anti-corrosive properties, allowing them to be applied directly to metal.
- VERSATILE APPLICATION: Suitable for use both above and below the waterline. (Prolonged submersion may cause the coating to soften over time.)
- DRYING TIME: Touch dry in 2-4 hours, overcoat in 12-24 hours, full protection properties after 7 days, so the substrate should not be submerged in water until this period has elapsed.
- COVERAGE: Approximately 8 square metres per litre. This does not account for the method of application, absorption of substrate or wastage.
- APPLICATION: Apply by brush or solvent-resistant medium pile rollers. This can aslo be sprayed.

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.
Full curing takes 7 days, so the substrate should not be submerged in water until this period has elapsed.
Be sure to stir the paint well before use.
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: This step is down to personal preference. Depending on the condition of the existing paint or if you are changing a dark colour to a light one, you may want to add one coat of primer.
If the material you are painting is fibreglass or metal and is showing you will need to spot prime with the appropriate primer. If there is rust this will need removing and spot priming.
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 substrate, it can cause delamination and lead to a loss of adhesion.
Step 2 -First Coat: Thin the first coat by 20% with T0001 White Spirit to ensure the paint impregnates the Wood, this will act as the primer/sealer.
Step 3 - Top coat: 12-24 hours after applying the first coat, you can apply the second coat of topcoat. Be sure to stir the paint well before use.
Painting bare Metal or Fibreglass.
Semi-gloss and Matt finishes have anti-corrosive properties, allowing them to be applied directly to metal. However, for complete protection, we recommend using a primer.
Step 1 - Clean and Prep: Ensure the substrate is dry and clean of any dirt, oil or grease. If there is any moisture on the substrate, it can cause delamination and lead to a loss of adhesion.
Step 2 - Prime:
Metal - If there is rust this will need removing and then priming with our High Build Zinc Phosphate Metal primer. If the substrate is exposed to harsh environmental factors, you can prime it with either Zinc Rich or our two-pack epoxy primer systems for optimal protection
Fibreglass/GRP/Gel Coat - Apply one coat of our Single Pack Fibreglass primer, as the topcoat will not adhere directly.
Step 3 - Top coat: Wait 12-24 hours after applying the primer before applying the first coat of topcoat. Then, after another 12-24 hours, apply the second 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 1:2 to 1:4 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.
