Materials Needed

If you’re new to surfboard making, you may be wondering what materials you need in order to get started. Fortunately, many of the essential materials for making a surfboard are widely available. The most common materials for making a surfboard are foam, fiberglass, resin, and wax.

In this section, we will break down the materials needed in detail so you can get the best possible start on your surfboard making journey:

  • Foam – used to create the surfboard’s core.
  • Fiberglass – used to reinforce the foam and create the surfboard’s shape.
  • Resin – used to provide additional strength and waterproof the surfboard.
  • Wax – used to provide grip on the surfboard.


Plywood is a versatile building material with many advantages. It is lightweight yet strong, relatively inexpensive and easy to work with. While there are many types of plywood available, marine grade plywood is the best choice when constructing a surfboard. It is constructed from high-grade wood that has been treated with waterproof glue for greater durability and resistance to moisture. An exterior marine finish (polyurethane or paint) should also be applied for further protection from the elements.

Generally, three layers of appropriate plywood should be used for optimal strength and durability. The top two layers should be carefully sanded and sealed to create a smooth surface before the board’s fiberglass cover is applied.


Using resin for a craft or other project requires certain materials, depending on the type of resin used. Both two-part epoxy and polyester resins are available in liquid form and must be mixed together prior to use. Additionally, there are other items necessary for the successful completion of any project which utilizes resin.

Both epoxy and polyester resins can be bought in two different forms: pre-mixed and hardener that needs to be mixed prior to use. Pre-mixed resins are ready to go right out of the container, while those requiring hardener need to have a specified amount mixed with them before they can be applied. In both cases, an accurate measuring device is paramount; even small differences in amounts can have disastrous results with these types of resins.

Besides the resin itself, fiberglass cloth or matting may also need to be purchased depending on the project. Project instructions will specify what amount should be used; generally speaking, at least two layers of cloth should be employed when using resin in any capacity as reinforcing material for strength. If a clear finish is desired sanding or buffing compounds can also aid in preparation for painting or coating afterward as desired. Proper masking and finishing materials should not be overlooked as well although these types of things vary from task to task so it’s best just to read up carefully on what is needed beforehand if unsure how much supplies will cost before starting a job utilizing resin material.


Fiberglass is the most commonly used material for surfboard construction. Most modern surfboards are made with a two-part process: a foam core and layers of waterproofing resin and fiberglass fabric.

It is important to choose the right type of fiberglass and resin for your surfboard project. There are several types of fiberglass, including E-Glass, S-Glass, Kevlar reinforced fabrics, and carbon fiber reinforced fabrics. The type used depends on the strength and flexibility desired in the finished board.

When selecting the correct resin system, there are several types suitable for use on foam boards such as polyester resins, epoxy resins, vinylester resins, or urethane resins. In addition to their physical properties, each has its own distinct characteristics in terms of working time (pot life), cure time (as it air dries) as well as how much dirt or dust gets picked up as it cures (called outgassing). It’s important to understand which product works best with your board before beginning your build process.

The tools required for a successful build can range from simple hand tools to more advanced power tools depending on the skill level of the builder. Basic items needed include a cutting tool for fabric (e.g., scissors, blade or utility knife) along with sandpaper or other abrasives needed for finishing edges or contours on your board shape such as those found around fins and nose/tail blocks. To help ensure even coverage on large surfaces during lamination processes spray applications with an HVLP spraygun might be necessary while thicker materials may require vacuum bagging equipment to ensure good resin penetration into fabrics during curing cycles.

Finally some basic safety equipment like gloves, goggles and respirators should always be worn when using these materials to help minimize exposure potentials when working with liquid li


Sandpaper is a general name used for a group of abrasive materials that consist of sheets of paper or cloth with abrasive material attached to one face. Sandpaper is commonly used to smooth wood, prepare it for painting, and remove minute amounts of material. Depending on what you are sanding, from wood to metal or plastic, the types and grits needed can vary significantly.

For light-duty home repairs involving wood surfaces such as furniture, cabinets and doors made from soft woods like pine or oak – use 80–150 grit sandpaper for fine sanding and stripping finishes. For medium-duty hobbies or repairs that involve sanding softwoods like cedar or redwood use 120–220 grit sandpaper for prepping surfaces for a finish. For harder woods such as maple or cherry use 180–320 grit sandpaper to create the smoothest possible surface prior to staining and finishing.

When using on metal surfaces such as tools, cars, trucks and other machinery – use 80–180 grit sandpaper if there are heavy rust spots; 150–220 if lightly oxidized; 250–320 if there are scratches; 400+ if only polishing is required.

Sandpaper grades can also be helpful when removing paint from indoor/outdoor surfaces including decks and walls made from plasterboard (drywall). Use coarse 40-80 grit material for thick layers of paint mixed with primer; medium 100-180 grit paper on trimming areas; finer 220+ grit paper when you get down to brightening the surface prior to refinishing.

The grade of sandpaper used can make all the difference between a successful project outcome versus mediocre results – so make sure you have the right type before starting any job!


When planning for a project, it’s important to make sure you have all of the necessary materials on hand before beginning. Finishing materials are the finishing touches that impart a finished appearance to the project, such as trim, fixtures, and hardware.

Here is a brief overview of the finishing materials you may need for most projects:

  • Trim – Trim includes molding, baseboard, window/door sills and casings. Trim adds definition to an interior space and often helps connect multiple elements together in a room.
  • Fixtures – Common fixtures include door knobs, cabinet pulls, drawer handles and hinges. Choose hardware that is appropriate for its function (i.e., whether it will support weight).
  • Hardware – Nails and screws come in many different sizes and finishes to fit your application specific needs; smaller gauge ones are suited for light-duty tasks while larger ones are better for heavy-duty use. Make sure you have enough!
  • Adhesives/Caulk/Putty – For repairs or installation projects that require adhesives or gap fillers such as caulk or putty; proper application will help secure items in place while adding extra aesthetic detail to your finished piece.
  • Paints/Stains/Varnishes – The type of paint finish desired affects how the wood material looks after being applied; stain and varnish may also be used for different types of protection or color accents depending on what type of look is desired.
  • Tapes & Fabrics – Tapes like electrical tape or duct tape provide additional structural strength where needed; fabrics can also add insulation qualities depending on the needed use (i.e., upholstery fabrics used in furniture pieces).

These items can help take any project from ordinary to extraordinary with just a few simple details! Be sure to always follow safety instructions when using any type of chemicals or materials mentioned above.

Preparing the Board

This guide walks you through the entire process of making a surfboard, from picking out the right materials to shaping the board. In this section, we will go over the steps you need to take before you begin to shape the board. It is important to get the board prepared correctly to ensure a quality board.

This includes:

  • Picking the materials
  • Marking the foam
  • Sanding the foam
  • Forming the stringers
  • Attaching the fins

Let’s dive in!

Designing the Board

Surfboards are designed to fit your needs and abilities. The design of the board will depend on your size, weight, surfing style, and wave conditions of your area. To decide how you want to design the surfboard, consider the following factors:

  • Length – Longer boards are more stable and easier to paddle but less maneuverable. Shorter boards are great for smaller waves, more practice turning tricks, and better mobility on bigger waves;
  • Width – Wider boards offer maximum stability while narrower boards give more performance in wave size;
  • Thickness – More thickness creates a slower but stable ride. Less thickness makes speedier turns;
  • Type of BoardChoosing a fish surfboard or hybrid surfboard depends on wave size personal preference;
  • Fin Set-Up – Research fin set-up for your board as it can make all the difference in performance.

Once you’ve considered these factors, it’s time to sketch out a few ideas for what kind of shape you’d like the board to have and any modification that is desired. Keep in mind that modifications can drastically change the way your board rides; be sure this is something you are 100% comfortable with before going forward. Additionally, remember that some shapes may require special tools or require extra skills that you may not have as a beginner shaper/surfer.

Cutting the Plywood

It is important to take your time when cutting plywood for any project. Plywood is a manufactured wood panel comprised of several thin layers, or plies, of wood veneer compressed and glued together. To ensure an accurate and clean cut, use a quality saw equipped with a sharp blade and make sure the blade is aligned with the line that you want to cut along. When cutting plywood at home, it’s recommended to wear safety glasses and a dust mask.

When making straight cuts, it’s ideal to use either a circular saw or a table saw because they provide greater control over the board and create neater edges. However, if you don’t have access to these tools, you can still make quality cuts using either a handsaw or powered miter saw.

For curved cuts in plywood pieces under one inch thick, use either an adjustable jigsaw blade or small handheld router following carefully drawn guide lines. For thicker plywood pieces (over one inch thick), use a band saw or saber saw with a fine-toothed cutting blade for smooth curves and angled cuts without tearing the wood grain apart.

Sanding the Board

Before you begin to sand your board, make sure you have the right equipment. Ideally, you should use an orbital hand sander with a 120-grit piece of sandpaper for the initial sanding. Do not use any kind of power grinder, as this could cause damage to the board.

When sanding, use light pressure along the grain of the wood. Work from one end to the other in a fluid motion and go over every area several times to even out any irregularities. After that, switch up to a 220-grit piece of paper and give it one last pass for extra smoothness.

When finished sanding, go over it again with a broom or vacuum cleaner to ensure that all the dust has been removed before applying your finish coatings.

Applying the Resin

Applying the resin is an important step in learning how to make a surfboard as it acts as a layer of protection. The resin will provide a waterproof and protective layer to ensure that the board will last. It’s important to apply the resin correctly in order to ensure that the board is strong and protected.

For this step, you’ll need a few tools and materials to help you achieve this. Let’s get into the details:

Mixing the Resin

Mixing resin correctly is a key component to achieving a successful, long-lasting finish. The ratio of hardener to resin should be carefully followed and all mixing should be done with proper care. Mixing systems such as those used in automotive refinishing may be used with industrial processes; however, these are not necessary in the home environment.

The resin is most often available in a two-part system with the hardener in either liquid or powder form. Before you begin, put on gloves and make sure you have adequate ventilation for the fumes that will be created during mixing. Always mix part A (resin) first then add part B (hardener).

Follow these steps for mixing:

  • Start by measuring out your desired amounts according to the manufacturer’s specifications and pour them into a clean container.
  • Slowly begin stirring and use an up-and-down motion – not a circular motion – for roughly six minutes or until it becomes uniform throughout with no clumps remaining.
  • Continue stirring for an additional two minutes.
  • Finally, allow it to stand for another five minutes before pouring it onto the surface you are applying it to.

Applying the Resin

Once the surfboard foam has been cut to the desired shape and form, it is time to apply the resin. This step is a critical part of building a surfboard, as the resin helps create the strength and structure that will give the board its shape and strength.

When applying resin, begin by using a plastic spreader or brush to evenly coat one side of the foam in glass resin. Glass resin creates strong bonds with fiberglass, which is what makes this material so popular for building surfboards. Avoid over-saturating your fiberglass with resin as it can lead to an uneven surface and increased weight from extra layers of material.

Take care when sanding your edges as well during this process; sand too much and you could end up weakening your board’s structural integrity. When you are done spreading out your glassed layer, lay down layers of fiberglass atop it to add strength to your board’s framework. You may need multiple layers of fiberglass depending on how much strength you would like in your board.

After applying multiple layers of fiberglass atop each another, add in a layer of epoxy-based wax between both sides of your board’s frame (top/bottom) for added protection against water damage or UV rays caused by extended sunlight exposure over time. Finally, finish off by adding a layer of glossy clear coat over top that not only seals off any moisture from getting through but also provides a smooth glossy finish for aesthetics as well as general hydrophobic qualities that help improve speed across waters when surfing!

Finishing the Resin

When you are ready to finish the resin, you need to prepare your surface by sanding it with very fine paper (600-grit). Then use a damp cloth to wipe away the dust. Next mix the resin according to manufacturer’s instructions and pour it into any low spots or divots that were in your board. Then spread a layer of clear finish over the entire surface with a roller, squeegee, or brush. Make sure you seal the entire board from nose to tail with one constant stroke.

Afterwards, run a heat gun over the fin box areas or use a hair dryer on high heat to remove any air bubbles under the surface. Finally, let your board sit overnight so that it can cure completely before proceeding with your project. It is essential to allow enough time for curing; otherwise the resin will not adhere properly and could weaken your surfboard’s integrity down the line.

Applying the Fiberglass

Applying fiberglass to a surfboard is an important step in the production and build process as it reinforces the integrity of the surfboard and makes it more durable. This process requires experience, knowledge and consideration for safety precautions.

Let’s dive into the details of applying fiberglass to a surfboard!

Cutting the Fiberglass

Cutting the fiberglass is one of the most important parts of making a surfboard. To properly cut the fiberglass, you will first need to lay it out and measure it according to your desired surfboard dimensions. It’s important to use a straight edge or ruler when measuring and cutting the fiberglass in order to get a clean, even edge. The exact method for cutting will depend on whether you are using woven or non-woven glass cloths.

For non-woven glass cloths, use a pair of sharp scissors to make long cuts across the grain of the material from one end to another without any sudden stops or turns. Make sure that all cuts are parallel with each other so that your finished product has evenly distributed fibres throughout its surface.

For woven fabrics, use either a regular Stanley knife with several replacements blades or an electric cutter powered by an electric drill. When using either method, take care to keep the blade as close as possible to the edge being cut so that you achieve an even finish around your entire board shape. Be careful when putting pressure on your cutter not to force it since this could cause mistakes in your shapes if they become distorted while cutting them out.

Applying the Fiberglass

Now that the foam has been shaped to create a surfboard, it’s time to begin adding the fiberglass cloth. The reason for the fiberglass cloth is to provide strength and rigidity so that the board can be used in water.

Fiberglass is a type of plastic made up of small, thin strands woven together. Fiberglass cloth will typically come in either a 6-ounce or 4-ounce weave size, which should be enough for most surfboard builds.

In order to properly apply the fiberglass cloth onto your surfboard, start by cutting the sheet into strips or swaths that fit over each section of foam. It’s best to cut pieces large enough so they can be draped over sections without much overlap and still completely cover each foam panel.

Next, wet out each sheet with resin until it’s completely saturated using a paintbrush or roller. Be sure to manage any pooling of resin on your building surface by applying it on an incline as you add more layers of resin/fiberglass alternately until you get the desired amount of layers desired- usually four-six layers depending on what size board you’re making. That way, any additional resin will flow away from the board instead of pooling beneath it and degrading its strength and integrity over time. Allow plenty of time (24 hours) for this layup period since waiting helps ensure full cure time for all four components: cloth, hardener, gelcoat, and sandpaper/finish gloss topcoat.

Finally, trim off excess edges with scissors or razor blade after curing in place to make sure all edges are even before proceeding to sanding and finishing process phase.

Finishing the Fiberglass

Once all the fiberglass layers have been applied, it’s time to finish the fiberglass. This is done by wet sanding the board with a sanding block and incrementally finer grades of sandpaper until you achieve a glossy and smooth finish.

  • Start with 80-grit paper and work your way up to 320-grit.
  • Make sure to use a finer grade if needed and keep the sandpaper moving over the surface at all times for even results.
  • When finished, wipe off any dust with a clean rag or towel and lightly spray the surface with some rubbing alcohol.
  • This will remove any trapped dust in the glass from the process of wet sanding and leave you with an ultra-smooth, shiny finish!

Finishing the Board

Finishing the board is the final step in making a surfboard and it is an important one. The finish will serve to protect the board from the elements but it will also make a huge difference to the appearance of the board. You will need to decide on the right type of finish for the board and you will need to execute it properly.

This section will provide all of the details on how to complete the finishing process:

Sanding the Board

Once the final shape of your surfboard has been determined, it’s time to start sanding. Sanding is important to take care of any imperfections and surface blemishes that have been byproduct of the shaping process. It will also help ensure a smooth surface so that the fiberglass, resin, and other coatings you may use adhere well to it.

The best way to sand a surfboard is with an orbital sander. This type of sander is circular and oscillates rapidly in order for it to create an even finish and reduce the amount of effort involved in sanding. When sanding a surfboard, it’s important to start out with coarse-grit paper (usually 80 grit) in order to remove most of the imperfections quickly but without creating too many scratches or gouges. Once most of these have been removed, you can move on up in grits from 100 – 100 – 180 – 220 – 320 in order to achieve a completely smooth surface finish prior to applying glass or other coatings.

It’s vital that pressure isn’t applied while using an orbital sander because this could cause irreparable damage; always let the machine do its work and slowly but surely you’ll get a perfectly polished board ready for its finishing touches!

Installing the Fin

The fin, or skeg, is one of the most important elements of the surfboard. It provides directional stability, allowing for maneuverability, speed, and control. Choosing a fin that matches your board size and design is important for optimal performance.

Installing the fin usually involves inserting the fin box into a drilled hole from the bottom of an already-shaped board. The process consists of measuring and cutting out shapes for the provided templates, then positioning them over each drill trace before finally positioning and gluing down the fin box in place. Be sure to wear protective gloves when performing these steps to avoid unnecessary cuts or scrapes from sharp materials.

Once installed, it’s time to slide in the actual fins. If you are using glass-on fins rather than FCS or Futures systems, you will need to use epoxy resin specifically formulated for adhering surfboard components such as fins securely in place along with fiberglass cloth if necessary. Hardening takes around 24 hours after which installation is complete! With FCS or Futures systems simply insert fins as indicated in each system’s instructions and snap into position securely – no extra glue necessary!


The process of making a surfboard can seem intimidating, but it doesn’t have to be. With the right materials, tools, technique and patience you can make a beautiful custom board for your own surfing pleasure. Just remember that the most important part of the process is planning; spend time researching various shapes and designs that will work best for your goals and abilities.

Be sure to take your time throughout the entire process to ensure quality craftsmanship and safety. Starting from a template or kit will reduce the risk of error, but don’t be afraid to customize components as you go along. With care and practice you can make a great board that you’ll be proud to take in the water with confidence!
