The different uses for Hawk Epoxy

If you’re a boat owner, there’s a good chance you’re familiar with Hawk Epoxy by SeaHawk Paints; however, did you know there are several diverse ways to use it? In this post, we’ll take a look at some of the different ways Seahawk Hawk Epoxy can be used to keep your boat in top condition. So, whether you’re a beginner or an experienced boater, read on for some helpful tips!

What is epoxy?

Epoxy is a type of adhesive that is commonly used to bond two surfaces together. It is made up of a resin and a hardener, which are mixed together to form a tough, durable bond.

Unlike other sealants, epoxy is able to form a strong bond with the surface it is applied to, making it an ideal choice for sealing concrete, metal, and glass. Epoxy is also resistant to temperature changes and UV light, making it ideal for use in outdoor applications. In addition to its practical benefits, epoxy can also be used to create interesting visual effects. When applied to a surface in thin layers, epoxy can create a marbled or even tie-dye effect. As a result, epoxy is a versatile material that can be used for both functional and decorative purposes.Epoxy is typically used for repairing metal, plastic, and glass.

It can also be used for bonding wood, concrete, and ceramic. Epoxy is available in both liquid and powder form. The liquids are typically used for small repairs, while the powders are better suited for larger projects. Epoxy is typically applied with a brush or roller. Once it has been applied, it needs to be allowed to cure for 24 hours before it can be used.

Hawk Epoxy can be used as a sealant to protect surfaces from water and other elements.

How To Patch a Hole in a Fiberglass Boat

A fiberglass boat is a great investment. They are durable and can last for years with proper care. But like anything else, they are not indestructible and will eventually need to be repaired. One of the most common repairs is patching a hole in the hull. Fortunately, this is a relatively easy repair that can be done by anyone with basic fiberglass repair skills.

The first step is to clean the area around the hole. This will remove any dirt or debris that could prevent the patch from adhering properly. Next, cut a piece of fiberglass cloth that is slightly larger than the hole. Apply a generous amount of fiberglass resin to the cloth and then place it over the hole. Use a roller or brush to smooth out the cloth and remove any air bubbles. Allow the resin to cure for 24 hours before sanding down the area and painting over it. With a little time and effort, you can have your fiberglass boat looking like new again.

A major fiberglass repair, such as patching a hole, can be a daunting task. Watching a professional do the job can help you get on the right track and be confident in doing the repair yourself.

Which Resin Should I Choose?

When it comes to boat repair, epoxy and polyester resins are both popular choices. But which one is the best option? Epoxy resin is known for its strong bonding properties, making it ideal for repairing cracks and holes. It also has excellent waterproofing qualities, making it ideal for boats that spend a lot of time in the water. Polyester resin, on the other hand, is a bit more flexible than epoxy, making it better suited for repairs that require some give. It’s also less likely to yellow over time, making it a good choice for boats that will be spending a lot of time in the sun. Ultimately, the best choice of epoxy or polyester resin for boat repair depends on the type of project you are tackling. 


General Purpose Repair Epoxy Resin Kit

Hawk Epoxy KitEvery household should own a Hawk Epoxy Kit like this. You can use it to repair anything around your home or own your boat. This kit comes with the resin, catalyst and your choice of filler. Just mix them together and you have an excellent bonding, filling, or adhesive paste.

FGCI General Purpose Resin is used for laminating with fiberglass, kevlar and carbon reinforments. It can be tinted with pigment up to 3% and best results are when used at 70-85 degrees F. Hardener varies depending on thickness of fiberglass, the more fiberglass the less hardener as you will generate more heat-never go below 1%. Complete cure needs sanding aid added to resin or PVA while still hot.

Polyester Resin:

MARINE ResinPolyester resins are unsaturated resins that are combined with hardeners, such as MEKP.

Polyester resin is used more for fiberglass lay-up or if you’re going to finish a repair with gelcoat, as the polyester resin will bond to the gelcoat better than epoxy. It is also cheaper than epoxy and a great choice when casting deep molds.

Various Types of Polyester Resin:

Boatyard Polyester Resin is a non-specified resin that contains different types of polyester resins and wax. Boatyard Polyester Resin is not recommended for use below the waterline. The material may cure hard and tack-free due to the included wax. If so, the product will need to be sanded prior to adding another layer in order to promote good bonding.

Clear Casting Polyester Resin is used to cast small objects into a mold. This method can be used to create sculptures, crafts, or industrial prototypes.

Surfboard Polyester Resin is Clear & wax free. It is ideal for building & repairing surfboards because it cures to an almost clear color when applied in a film. Also it highlights underlying graphics.

Iso Marine Resin is based on isophthalic acid. This resin is a step above the general purpose polyester resin and that is reflected in the price. Iso Resin is stronger, more durable, and is the best choice when applying in corrosion environments or elevated temperatures.

Vinyl Ester Resin:

Vinyl ester resins are formulated with a base of polyester resin strengthened with epoxy molecules (a hybrid form of polyester and epoxy and aiding for gelcoat to bond with epoxy) and also use peroxides, such as MEKP, for hardening. These are cheaper than epoxy resins and more expensive than polyester. Ideal temp for use is 77 F, not applied over 1/8th thickness or it will generate too much heat.

Vinyl esters are more tolerant of stretching, less likely to show stress cracking and more resistant to water penetration. Vinyl ester is the choice when improved resistance to moisture is the goal (like repairing a blistered hull).

Long term water exposure (hull or water tank) or if impact resistance is important vinyl ester is usually chosen.

Epoxy Resin:

Epoxy resins are cured with the addition of a hardener. Unlike the polyester and vinyl ester resins, cured with a small amount of catalyst, epoxy resins usually require a lot more, often 1:1 or 2:1. A epoxy resin is the most expensive of these.

Epoxy resin has the best bonding strength as it will bond dissimilar or already cured materials for strong, reliable repair work. This is the most expensive resin but offers the most in its ability to flex, prevent delamination and ease of repair work.

If doing a repair and not overlaying with gelcoat then the epoxy will perform best as it tends to act as a stronger “glue” for the patch to the surrounding surface.

Laminating Epoxy Resin is the correct choice for repairing boats. It is super durable and has high resistance to water. Also, it has very good adhesion to a variety of surfaces including metals, plastics, fiberglass, wood, and glass.  The ratio is well suited for use with high-solids marine, maintenance coating and bonding agents.  The cure time is three days in the sun or a week if it is not. Set time changes with activator and film thickness.  If there is an excessive amount of activator applied , the laminating epoxy will be soft and rubbery. In contrast, if there is not enough activator, the epoxy will not cure hard. Laminating Epoxy is available in 3 different ratios that provide different working and cure times.


Epoxy Resin (Bar Top Epoxy Resin):

A Premium Commercial Grade Clear Epoxy Resin – Klear Kote Epoxy Resin is used extensively in coating surfaces and in table tops where a clear, hard and durable coating is required. Commonly seen on bar tops and restaurant tables. Easy to use 1:1 mixing ratio of resin and hardener.  Items coated with it will become permanently preserved and protected for your enjoyment throughout a lifetime. The epoxy resin will not exhibit blushing or sweat out under high humidity conditions.

Epoxy Resin Kits

epoxy resin kit

Epoxy resin kits are sold in two parts, A and B, which should be applied in two stages. The first stage is referred to as the seal coat. The seal coat is brushed on in a thin layer and is used to seal any pores on the surface and prevent air bubbles from forming in the following flood coats. This stage is followed by the flood coat, which will flow and self-level, clean brushes or squeegees can be used to help spread the epoxy. Flood coats are applied in 1/8″ layers at a time, as many as desired can be applied, however, one to three coats is average for most table or bar coatings. Resin kits are often applied on bar tops and tabletops in many bars and restaurants.

Superbond Standard Epoxy Glue

Superbond Standard Epoxy Glue is a two-part, 1:1 epoxy adhesive that has a Vaseline consistency. The product adheres to nearly everything and is a favorite among woodworkers. It’s offered in a fast curing agent, giving 8-15 minutes of working time; a medium, giving 20-30 minutes, and a standard, offering 30-45 minutes. SuperBond is offered in sizes from ½-pint tubs all the way to 5-gallon pails.

Rot Stop Epoxy

Rot stop epoxy is a 2-part epoxy that is 1:1 ratio and is very simple to mix. The coverage is similar to other epoxies, and like other epoxies, the product does vary in thickness based on temperature. The advantage of Rot Stop is it is NOT affected by moisture, making it excellent for deck or flooring and cracking repair, especially moisture damage.

See catalyst chart for mixing guidance:

MEKP Chart
The weight of MEKP is 1/125 grams per CC. 30 Drops is approximately equal to one CC (Cubic Cementer)
NOTE: Using drops for catalyst is only an estimate. In Critical applications MEKP should be measure by using CC’s or Fluid Ounces which are volume measurements. The percentages in the chart: 1% thru 2% are percentages of gelcoat by weight.The CC’s and OZ’s values in the chart have been converted from weight of MEKP to volumes of MEKP.

Resin guns

Gelcoat and resin spray guns are ideal for large surface spraying, such as new mold construction, composite refinishing and large boat surfaces.  Look for a resin gun with a blue die cast body which will ensure a long life. Most HVLP cup guns use nylon flat seal just behind the threads that the air cap attaches to.

If you have used a spray gun with a nylon flat seal just behind the threads that the air cap attaches to and cleaned it with acetone, the seals disintegrate so it is best to use one with a plastic seal.
