Application methods: brushing, rolling, tipping, or spraying

Marine paint can be applied using a variety of methods, each with its own advantages and disadvantages. Here is a detailed guide on the four main application methods for BlueWater Supreme Urethane Marine Paint:

Brushing

Brushing is a common method for applying marine paint. Natural bristle or badger hair brushes are recommended for this process. When brushing, always work from the wet edge of the previously painted area into the new paint. This technique ensures a smooth and glossy finish.

Rolling

Rolling is another option for applying marine paint. It is recommended to use a solvent-safe 1/8" foam roller, which is designed to leave a glossy finish without any stipple or lint. The 'roll and tip' method, which combines rolling and tipping, can also produce excellent results.

Tipping

Tipping is often used in combination with rolling, in a technique known as "roll and tip." This method involves using a brush to tip off the paint after it has been applied with a roller. This helps to create a smooth and glossy finish.

Spraying

Spraying is an alternative application method for marine paint. It can be used to achieve a uniform and efficient coating. However, spraying equipment may require additional investment or rental.

Primer: use TotalBoat Topside Primer for best results

When applying BlueWater Supreme Urethane Marine Paint, it is important to use a compatible primer to ensure the paint adheres properly. TotalBoat Topside Primer is a great choice for this purpose, as it is designed for use with one-part polyurethane and enamel topside paints, as well as two-part polyurethane topside paints. This primer is easy to apply and dries quickly, forming a hard finish that won't lift or crack. It can be applied to wood, fibreglass, gelcoat, and previously painted materials above the waterline.

To achieve the best results with TotalBoat Topside Primer, follow these steps:

Prepare the Surface: Ensure the surface is clean and smooth. If there is existing paint, remove any signs of separation, cracking, or peeling by scraping and sanding down to the bare substrate. For previously painted surfaces or epoxy coatings, remove any amine blush with soap and water, rinse thoroughly, and dry completely. Then, lightly sand the surface and remove the sanding residue with a clean, lint-free rag dampened with TotalBoat Dewaxer and Surface Prep. Allow the surface to dry completely before proceeding.

Apply the Primer: TotalBoat Topside Primer can be applied by brush, roller, or spray. When brushing, thin the primer with TotalBoat Special Brushing Thinner 100. For spraying, use TotalBoat Spray Thinner 101, and use a 1.1mm tip. In cooler temperatures, Spray Thinner 101 can also be used for brushing. Remember to apply the primer thinly and evenly, as recommended by the manufacturer. A single coat is typically sufficient for most applications.

Allow Drying and Curing: The dry time for TotalBoat Topside Primer varies depending on temperature. It can take anywhere from 10 minutes to 1 hour to dry to the touch, and up to 4 hours to fully cure. The primer is sandable within 60-90 minutes at 65°F. Ensure the primer is fully cured before proceeding to the next step.

By following these instructions for using TotalBoat Topside Primer, you will create a strong and durable foundation for your BlueWater Supreme Urethane Marine Paint, resulting in a high-quality and long-lasting finish.

Painting tools: solvent-safe foam roller, natural bristle or badger hair brush

When applying BlueWater Supreme Urethane Marine Paint, it is important to use the right tools for the best results. In this case, the recommended tools are a solvent-safe foam roller, a natural bristle brush, or a badger hair brush.

A solvent-safe foam roller is designed to withstand solvents and paint thinners, making it ideal for use with urethane-based paints. Foam rollers provide a smooth finish and are commonly used in marine applications. They are also known for their ease of use and convenience, making them a popular choice for painters of all skill levels.

Natural bristle brushes, on the other hand, are made from natural animal hair bristles, typically boar or horse hair. These brushes offer benefits that synthetic brushes cannot provide, including improved hair and scalp health. Natural bristle brushes are effective when used on hair that is not freshly washed and can help lengthen the time between washes.

Badger hair brushes are another option, but they come with ethical concerns. Most badger hair is sourced from China, which has been associated with the unethical treatment of captive animals. Synthetic alternatives have improved significantly, offering comparable or even superior performance to natural hair brushes. Ultimately, the choice between synthetic and natural brushes depends on personal preference.

When applying BlueWater Supreme Urethane Marine Paint, consider the benefits of each tool and choose the one that best suits your needs. Whether it's the smooth finish of a solvent-safe foam roller, the natural qualities of a natural bristle brush, or the traditional choice of a badger hair brush, each option has its advantages for achieving a high-quality paint finish.

Number of coats: apply two coats of 1.5 to 2.5 mils WFT each

When applying BlueWater Supreme Urethane Marine Paint, it is important to note that the number of coats will depend on the desired finish and protection. For the best results, it is recommended to apply two coats of 1.5 to 2.5 mils WFT each. This will ensure that the paint job is uniform and provides adequate protection for the boat's surface.

It is important to allow adequate time for drying between coats. Approximately 16 hours should be allotted between the first and second coats. This will ensure that the paint has cured sufficiently and will result in a smooth and durable finish.

To achieve the specified thickness of 1.5 to 2.5 mils WFT per coat, it is recommended to use a wet film thickness gauge. This tool allows you to measure the thickness of the paint as you apply it, ensuring that you are within the specified range. A wet film thickness gauge provides accurate measurements and helps avoid applying too much or too little paint.

Additionally, proper surface preparation is crucial for achieving the desired thickness and a smooth finish. The surface should be clean, dry, and free of any contaminants. Depending on the substrate and its condition, appropriate primers or epoxy systems may be necessary. Following the manufacturer's recommendations for surface preparation and primer selection will ensure a successful paint application.

By following these instructions and allowing adequate drying time between coats, you will achieve the desired thickness and a high-quality finish with BlueWater Supreme Urethane Marine Paint. Remember to refer to the manufacturer's guidelines and safety instructions for the best results and to ensure your safety during the application process.

Time between coats: allow 16 hours between coats and sand with 280 to 400 grit paper

When applying BlueWater Supreme Urethane Marine Paint, it is important to allow ample time for the coats to dry and cure properly. The manufacturer recommends allowing 16 hours between coats. This gives each layer of paint sufficient time to dry and ensures that the subsequent coat can adhere properly.

During this 16-hour interval, you also have the option to sand the painted surface with 280 to 400 grit paper. Sanding between coats is an important step to achieve a smooth and uniform finish. It helps create a level surface by removing any minor imperfections, brush strokes, or bumps that may have formed during the previous coat's application.

The grit size of the sandpaper, ranging from 280 to 400, strikes a balance between effectiveness and gentleness. A finer grit, such as 400, will provide a lighter sanding, preserving the coat while smoothing out minor imperfections. On the other hand, a slightly coarser grit of 280 will offer more aggressive sanding, which can be beneficial if there are significant irregularities or if a more pronounced texture is desired.

By following these guidelines and allowing the recommended time between coats, you can ensure that your BlueWater Supreme Urethane Marine Paint project achieves a professional-looking and durable finish. Remember that factors such as temperature and humidity can influence drying times, so it is always advisable to refer to the manufacturer's instructions and recommendations for the best results.
