I’m looking for a surfboard epoxy resin that will be good for my board. I’m wanting to make sure before I buy it, what is the best way to know how much I need?
There are so many different types of surfboard epoxy resins and they all seem like they would work similarly.
How much resin do I need for one board?
A good rule of thumb for a surfboard is to use about two liters or one quart per board.
If you do not have the exact volume at home, this would be a good amount to start with if your board needs repair.

How do you calculate resin for fiberglass?
The resin ratio for fiberglass is usually between 100-150 grams per square foot. To calculate the correct amount of epoxy, you’ll need to know how much area your board has so that can be converted into square feet.
The best way to do this is by measuring the length and width in inches (or centimeters) then multiplying them together to get square footage or cm squared x 0.3937 = square meters.
How much resin do I need for Fibreglass?
The amount of epoxy resin required for a Fibreglass surfboard depends on the weight and thickness, to give you an idea about how many liters can be used here are some general figures:
– Boards up to 220cm long x 50cm wide (820 cm^²) will take approximately 0.75 liters – this is sufficient for one layer application.
– If two layers or more are applied to these boards then they should take between 1250ml and 1500 ml per board depending upon their width & length etc…
For reference, 1000ml=0.264 Gallons = 0.22 Imperial Gallon / 37 US Fluid Ozs – so consider that when purchasing your resin!
How much resin do I need for a boat?
The amount of resin you need for a boat will vary depending on the size and type of boat.
In general, you will need about 0.75 liters of resin per square meter of surface area.
You may also want to add fiberglass cloth or other reinforcements to your project for added strength.
Consult with your local boat builder or epoxy supplier for more specific advice on how much resin you’ll need for your project.
If you’re working on a surfboard, you’ll need even less epoxy resin – about 0.35 liters per square meter.
Again, be sure to consult with a professional if you’re not sure how much resin to use.
Epoxy is an extremely durable adhesive and can withstand the harsh conditions of the ocean, but it’s important to use just enough resin for your project.
Moreover, you can always mix up a small batch of epoxy and try applying it to see how much you need before mixing up more than is necessary.
You’ll also want to be sure that your work area is well-ventilated when using epoxy since the fumes are harmful if inhaled or left in contact with skin too long.
Additionally, make sure you wear gloves while working with this adhesive – even after the curing process begins! If epoxy resin gets on your hands while uncured, wash them immediately with soap and water because once cured there will no longer be any adverse effects from exposure.
How much resin do I need for 1 surfboard?
In order to determine how much resin you will need, please follow these steps:
– measure the total weight of your surfboard. Make sure that board is not wet and it’s cleaned off before weighing. Soaking in water can add up to 15 lbs on this measurement.
Then dry with a towel or paper towels so surface moisture is gone but won’t cause problems with adhesion later on when applying epoxy resin.
After drying completely set the scale back on zero then reweigh board for an accurate reading.
The average surfboard full of foam weighs between 20-30 pounds depending upon the size of course—a larger longer heavier surfboard obviously weighs more than a smaller shorter lighter one like say a fish shape would weigh less.
– multiply this number by .07 to determine the weight of epoxy needed for your surfboard.
This is a good basic rule of thumb but can vary depending on how much glass or lamination you are adding to board if any at all—adding more fiberglass will make it heavier and require slightly less resin than before.
If you’re applying other materials like carbon fiber then there’s no need to add extra resin since only the wood needs reinforcing with that lightweight material which has its own adhesive properties already built-in as well as being water-resistant when cured properly using a heat gun or oven respectively.
For example, 30 lbs x .07 = 21 ounces so approximately two full bottles would be enough assuming else was added during construction process and is not included in this calculation.
But let’s say you added carbon fiber on deck and rails which add around half a pound per square foot then order one additional bottle for resin.
That would make two bottles or 42 ounces needed—three full bottles to be safe if building a nine-foot board with no other materials applied besides glass job already mentioned above.
What resin is best for surfboard?
Generally, surfboard epoxy resin is divided into two major types. The first type of resin is polyester resins and the second one is epoxied.
Polyester is cheaper compared to the later ones but its performance in terms of abrasion resistance isn’t very good.
On the other hand, Epoxies are much more expensive than polyesters but they have better strength which makes them an excellent choice for building a board that will be used all year round including wintertime when waves aren’t so big or frequent as during summer months.
How much does 2 gallons of resin?
Epoxy resin is typically sold in either quarts or gallons. Most surfboards require about two gallons of resin, but it’s best to consult with a professional if you’re unsure about how much you’ll need.
Resin is an important part of the surfboard-building process and should not be underestimated.
Make sure to get the right amount so that your board turns out exactly the way you want it.
How much resin will I need?
This is a difficult question to answer without knowing more about the board. A good starting point would be around 18 ounces, but you may need more or less depending on the size and shape of your board.
If you’re not sure how much resin to use, it’s best to overestimate and have too much than not enough.
Too little resin can cause problems like delamination and weak spots in your board.
How much does 1 gallon of fiberglass resin cover?
A gallon of resin will cover about 80 square feet. So, if you are making a surfboard that is six feet long and two feet wide, you will need about half a gallon of resin.
If you are using a fiberglass cloth with a weave size of 24 inches by 24 inches, then you will need four sheets of cloth.
Make sure to allow for enough extra material to wrap around the edges of the board.
You can use less resin if your surfboard is smaller or if you are using a smaller weave size on your fiberglass cloth.
how to glass a surfboard with epoxy?
The first step is to mix the resin and hardener according to the manufacturer’s instructions. You will need to use a ratio of two parts resin to one part hardener.
Next, you will need to apply a coat of epoxy resin to the entire surfboard. Make sure that the surface is even and free of any bumps or imperfections. Allow the resin to dry completely before moving on to the next step.
Finally, you will need to apply another coat of epoxy resin to the surfboard. Be sure to smooth it out evenly and allow it plenty of time to dry before using your new board!
how much to glass a surfboard?
Epoxy resin is used to make surfboard glassing easier. The epoxy helps the fiberglass adhere better to the wood, and it also adds structural integrity for when you are surfing at high speeds.
It comes in various weights according to density, which can vary from 100 grams per liter (g/L) to 500 g/L or more.
I recommend staying under 400 g/L if possible; anything above that makes it difficult for your board shaper to wet out properly with their heat gun because of its thickness.
