3 best gel coat

Gel coat is a specialized type of coating commonly used in the boating and marine industry for the protection and finishing of fiberglass boat hulls and other fiberglass-reinforced structures. Here's what you need to know about gel coat:

  1. Protective Layer: Gel coat is applied to the outer surface of fiberglass structures to create a protective, waterproof layer. It helps shield the underlying fiberglass from the harmful effects of water, UV rays, and environmental factors.

  2. Appearance: Gel coat is available in various colors and finishes, allowing boat owners and builders to customize the appearance of their vessels. It provides a glossy and attractive finish that enhances the aesthetics of the boat.

  3. UV Resistance: Gel coat is highly resistant to ultraviolet (UV) radiation, which is essential for maintaining the appearance of boats exposed to sunlight. It prevents the fiberglass from becoming faded or discolored over time.

  4. Waterproofing: Gel coat is impermeable to water, preventing water penetration into the fiberglass laminate. This is crucial for preventing osmotic blistering, a common issue in fiberglass boats where water can get absorbed into the hull.

  5. Repair and Restoration: Over time, gel coat may become scratched, faded, or damaged. In such cases, it can be repaired or restored by sanding and reapplying new gel coat, making it a durable and long-lasting finish.

  6. Application: Gel coat is typically applied in multiple layers, with each layer being allowed to cure before applying the next. It is often sprayed or brushed onto the fiberglass surface during the boat manufacturing process.

  7. Thickness: The thickness of gel coat can vary depending on the specific application and manufacturer. A thicker gel coat layer provides better protection but may require more skill to apply evenly.

  8. Maintenance: To maintain the appearance and protection of gel coat, regular cleaning and waxing are recommended.Waxing can help to restore shine and provide an extra layer of protection.

  9. Availability: Gel coat products are readily available in marine supply stores and online retailers, making it accessible to boat owners and enthusiasts.

It's important to note that while gel coat is highly effective at protecting fiberglass surfaces, it can still become damaged over time through normal wear and tear. Proper maintenance and occasional reapplication may be necessary to keep the gel coat in optimal condition and ensure the longevity of your boat's appearance and structural integrity.

User questions & answers

Question: can this be sprayed on? And how many square feet does it cover
Answer: This is a thick lotion like liquid that needs to be applied and worked by hand or machine and then wiped off. Please feel free to give our Solutions Hub a call at (800) 347-5700 to discuss the specifics of your job. Any of our reps will be happy to help you figure out the best process and products with you.
Question: Can this gelcoat be tinted with pigments
Answer: Oxidation remover is more of a rubbing compound that cleans deep down to new fiberglass and has enough wax to leave a shine. 'One Step' is also a cleaner but not nearly as aggressive and has more wax. Both are superb, but for different degrees of oxidation.
Question: I have a jetski with pits in hull,can i just paint this on and apply a couple of coats,after prepping it and what would be best,with or without wax
Answer: I tried to remove oxidation from the sides of my Cougar fifth wheel trailer with little to no success. I tried to rub it out both by hand and with a power buffer. I am having more success with TR3 but the product I have is old and I have been told the formulation has changed and the new product is not as effective. It is a lot of work regardless of what you use and the end result for me was disappointing.
Question: Will this product run, or can it be molded to hold the desired shape
Answer: Hi i bought. A gal of it i have a 38 ft fifth wheel it is 12'6''tall we used about 2/3of it the hole thing is glass ,it was the best i ever used ,easy on easy off ,shines like a cats butt,it workes great !!!!!

TotalBoat ISO/NPG Gelcoat is Stronger, More Flexible, More Durable, and Easy to Apply.

TotalBoat marine-grade ISO/NPG Gelcoats are the choice of pros for many boatbuilding and boat repair applications due to their greater strength, flexibility, and resistance to weather, water, and chemicals than standard orthophthalic polyester gelcoats. Available with and without wax, TotalBoat Gelcoat With Wax cures tack free to a hard, sandable finish perfect for air dry applications, such as coating. Cured gelcoat can be wet sanded, buffed, and polished to a protective, head-turning, high-gloss finish. TotalBoat Gelcoat Without Wax remains tacky. It's commonly used as the initial layer in polyester resin layups. Our premium Gelcoat comes in White and Neutral colors that are compatible with colorants (pigments / tints) for gelcoat and polyester resins. For best results, be sure your gelcoat and your work area are between 70°F and 95°F.

Adjust the Amount of Catalyst from 1-3% to Control the Setup Time in Different Temperature Conditions.

With polyester gelcoat, proper catalyzation is critical for a proper cure. Cool temperatures may require adding a higher percentage of MEKP catalyst than warm conditions. The more catalyst added, the faster the gelcoat cures. Because air and surface temperatures also affect dry times, take care not to over-catalyze or under-catalyze. We recommend a trial batch to determine final catalyst ratio.

Can be Tinted with Pigments Suitable for Gelcoat and Polyester Resins

Adding color to white gelcoat creates lighter, pastel colors. Adding color to neutral gelcoat creates bold, darker colors. TotalBoat White Gelcoat (with wax or without wax) can be tinted by adding up to 1% colorant. TotalBoat Neutral Gelcoat can be tinted by adding up to 10% colorant (up to 12% for red, yellow, purple, orange, and light green).

IMPORTANT: Always mix in colorant before adding MEKP.

Ideal for Coating

TotalBoat Gelcoat With Wax cures to a hard, durable coating that can be wet sanded and buffed to a super high gloss finish. Use on powerboat and yacht hulls, RVs, composite parts, and much more.

Great for Layups

Apply TotalBoat Gelcoat Without Wax to a mold prepared with mold release agent, then apply a fiberglass laminate over the tacky gelcoat. Works great for spray-up or hand layup techniques to create molded fiberglass boats or composite parts.

Compatible with Colorants

TotalBoat Gelcoats can be tinted to achieve a desired color. TIP: When tinting, always mix in coloring agent before adding MEKP.

  • Tinting TotalBoat White Gelcoat (with wax or without wax) creates lighter, pastel colors. Add up to 1% polyester resin or gelcoat colorants.
  • Tinting TotalBoat Neutral Gelcoat (with or without wax) creates bold or darker colors. Add up to 10% polyester resin or gelcoat colorants (up to 12% for red, yellow, purple, orange, and light green).

Perfect for Cosmetic Repairs

TotalBoat Gelcoat repairs cosmetic damage easily. It can be applied over cured polyester or vinyl ester fairing compounds, then wet sanded and buffed to a high-gloss finish, for a repair that blends in with the surrounding gelcoat. But what if you used an epoxy fairing compound?

Can you apply TotalBoat polyester Gelcoat DIRECTLY over a repair faired with an epoxy-based fairing compound? The answer depends on a few things.

• If the repair area is small, if the damage is cosmetic only (not structural), and with proper surface preparation—yes, TotalBoat Gelcoat can be applied directly over cured epoxy-based fairing compound.

• If the repair area is large, and if the damage compromises structural integrity—the answer is no. In these cases, you would fill the damage with an epoxy-based fairing compound such as TotalBoat TotalFair, allow it to cure, then apply TotalBoat 2-Part Epoxy Primer or TotalBoat TotalProtect Epoxy Barrier Coat Primer over TotalFair, before applying Gelcoat.

It all started simply enough. As boaters, we wanted better stuff for our own boats.

Even our favorite products, the ones we'd come to rely on, had room for improvement. It'd be nice if they could hold up longer, cure faster, coat better, apply easier, and—since we all know boat ownership creates a mini maelstrom in your pocket—cost less. So we took everything we knew from 35 years of customer feedback, combined that with our own boating knowledge, and after a few years of rigorous R&D, TotalBoat was born. Launched, rather. By boaters, for boaters.

User questions & answers

Question: Does this come with hardener
Answer: Yes it does.
Question: Can it be applied with a roller
Answer: Yes, it can be applied with a roller.
Question: Does this require that you cover it with plastic in order to cure it
Answer: No, the wax “floats” to the surface and promotes curing. Gelcoat without wax needs to be covered with a thin film like PVA.
Question: I'm looking to refinish a cultured marble counter-top. Is this a hard surfaced coating that will hold up in a sink
Answer: I would doubt that this would hold up in a sink application. Try the manufacturer.
