How to Choose The Best Gel Coat For Boats

Premium isophthalic NPG (n-gluene propylene glycol) based polyurethane gel coat is more durable than regular orthophthalic gel coat for various boat repair and restoration projects. Formulated for attractive results with hand and spray-on applications only. Easy to apply, cured, and durable gel coat provides a high-quality finish with superb coverage. Cured gel coat sands to a hard, durable finish and is easily cleaned with soap and water.

A pre-cured gel coat prevents leakage or bubbling during any boat repair or renovation project. It seals the mold surfaces and helps reposition the mold, increasing the mold flow rate. Ideal for all-weather boat coverings, it provides good coverage and durability. Curing agents are usually applied over the gel coat, which penetrates and bond to the mold surface. The curing agent penetrates and bonds to the mold because it is cured at low pressure.

Boat gels provide a one step finish to marine structures. It is a simple process that makes this an economical choice for protecting and lengthening the life of sailboats, dinghies and powerboats. It is a very effective marine solution for any repair and finishing needs.

Painters love it for easy maintenance and versatility. It is an excellent sealer that helps protect the surface of boats from acid deterioration, preventing flaking. It is ideal for protecting metal from corrosion, rust and flaking. It can be used for any type of paint application including electroplating, electrohydraulics, die cutting and bonding, providing an increased protection to the structure.

Its smooth application and seamless mixing allows easy application on any size of vessel. It is an economical choice that is ideal for boat repair and painting. One step finish offers a fast drying time and reduced cost with greater flexibility and durability. It comes in a variety of colors and finishes. Its low cost and quick drying makes it a great choice for any type of restoration.

It comes in many forms, including sheets, tiles, films, plasters and rolls. It is a versatile product that enhances the visual appearance of boats while providing additional protection against moisture and corrosion. Boat owners and designers use it for hull restoration, protection and lengthening the life of sailboats. Many manufacturers choose this flexible product for boats, boatswainships and other watercraft.

Its high heat setting and flexibility make it a good choice for any type of watercraft repair and painting. It is a waterproof, durable and pliable surface coating that provides protection from rust, moisture, mildew, chemicals, corrosion and weathering. The coat can be applied in many different configurations including flat, textured and gloss, making it ideal for any type of vessel. It comes in both solid and hollow components. Rigid versions are suitable for use in boats and rigid plastic versions are good for vessels that require a heavy-duty marine paint.

It is important to note that when applying a gel coat for boats, the boats must not contain any oily or waxy coatings or waxes. Allowing any of these materials to remain on the boat may lead to adverse effects, such as a hardening and cracking of the composite materials. In the past, epoxy resins were the only choice because it contained oils that made it suitable for marine applications. However, recent technological advances have allowed manufacturers to develop unsaturated polyester resins that are as effective and reliable as the acrylic versions. Both types of resins are equally suited to repairing scratches, abrasions and damage caused by exposure to the elements.

Although epoxy resin is the most common choice for boats, its durability makes it a poor choice for vessels that see high-stress environments. In fact, it is an acknowledged marine application that using epoxy resins on a boat that experiences a lot of motion or is frequently exposed to harsh weather conditions, may actually degrade its overall quality. In addition, epoxy resins are sensitive to temperature fluctuations; over heating can actually accelerate chemical reactions that can lead to accelerated deterioration of the vessel's surface. There are marine grade products that have been developed specifically to address issues related to chemical exposure, thermal damage, wind and salt spray protection and mold growth.

If you own a boat that experiences regular exposure to sunlight, a good quality marine grade gel coating will not degrade over time. If you live in a climate where the sun's rays are powerful, a high SPF coating is advisable. An appropriate coating will help to block the ultraviolet (UV) rays from reaching the inside of your boat. Ultraviolet light has been shown to cause a variety of marine disorders, including blistering and cracking of the hull. Sunlight, although powerful, is not the only thing that causes damage to a boat's interior.

Boat repair professionals recommend the incorporation of a high-quality epoxy resin on a regular basis. A majority of boats will experience some type of repair or maintenance at some point. Typically, this will involve painting the surface and applying a sealer. Although most people do not think about the role that conditioning and sealing play in preventing further deterioration, sealing the surfaces of the boats keeps future damage from being able to happen. If you decide to go down this road to protect your investment, be certain to consult with your repair technician so that you will receive the most effective product.
