Marine Epoxy Fairing Compound
Smooth Almost Any Surface


#4114 Marine Epoxy Fairing Compound is a smooth, creamy paste system for fairing large surface imperfections on fiberglass, wood, aluminum, and steel. This tough Marine Epoxy Fairing Compound is UV stable, weather resistant, and can be used above or below the waterline. This Marine Epoxy Fairing Compound is versatile and can be used for fairing or surface repair on wooden marine vessels, wood cabinets, fiberglass structures, and architectural items. It is even used for finishing surfaces in clean room applications. #4114 can be sanded to an excellent finish, meaning there is no need for a finish coat.

When mixed at an easy 1:1 volumetric ratio, this creamy paste can be spread easily onto damaged or rough areas to create a smooth, cosmetic surface. This color coded kit (white resin/brown hardener) indicates when a complete mix has been achieved. Apply this compound up to 1" thick with very little shrinking or sagging during cure. When cured, Marine Epoxy Fairing Compound can easily be sanded and can accept most types of primers and paints.
Styrene Thinner
General Purpose Styrene


Styrene is primarily used to thin polyester resin and gel coat before use. This is not a necessary step for the resins or gel coat on FibreGlast.com, but simply a preference for handling purposes.
  • When added to polyester resin, it enables and speeds the resin infusion process for vacuum bagging.
  • Fabricators may thin gel coat 2–5% with styrene to make them more suitable for heavy spray equipment.
Red LDPE Infusion Flow Media
Controlled Resin Channels

Our #1405 Red LDPE Infusion Flow Media is used for small to medium resin infusion projects, up to 50sqft, that require predictable, controlled resin flow. This flow media is designed to assist resin flow through your composite part during the resin infusion process.

In addition to having a high degree of conformability, this LDPE does not fray or roll up when cut, making it easy to position within your vacuum bag. This flow media can also be used on larger projects if multiple resin ports are installed on a single part. With a service temperature of up to 160 degrees Fahrenheit, #1405 is compatible with most composite manufacturing techniques and all of our resins. It is available in multiple roll lengths, all rolls are 60" Wide.
6K, 5HS Weave Carbon Fiber Fabric
10.9 oz/sq yd, 50" Wide, 0.024" Thick, 6K, 5HS Weave Construction


With twice the fiber density of 3K fabric selections, the 5-Harness Satin Weave builds quickly to form lightweight structural applications that feature virtually no flex. Its unique satin weave features carbon fibers bundled and woven repeatedly to float over four bundles, then under one. As a result, the fabric is flatter and more easily draped over the most complex shapes, especially compared to plain or satin weaves.

Because of its unique satin weave, one side of the fabric will look different than the other. Fabricators will usually invert half the plies when looking to produce a symmetrical laminate.

To maximize fabric properties, use with an epoxy resin, like our #2000 system, or a vinyl ester, although polyesters will bond to the fabric.>

Fibre Glast is committed to ensuring that every roll of fabric we handle is First Quality and manufactured to the highest standards, so that you can expect the same properties and handling characteristics every time you order.

Typical full roll length is 100 yards.
Chopper Gun
Quick Glass Build Up

Our 1171 is a hand held, variable speed air powered chopper gun that is primarily used for coating molds or parts with fiberglass or carbon fiber reinforcement. Continuous glass roving is fed into the rear of the gun. The gun then chops the roving into short pieces and deposits them onto the mold. Resin is then applied by brush, roller or sprayed on using a cup gun.

By altering the number and location of chopper blades, the length of the fibers can be varied from 4" down to 5/16". This gun will deposit the equivalent of one layer of 1 oz mat onto a vertical surface without fall-off before wet-out. Ideally suited to quick mold or part build-up once the first layer or two are in place.

Use a fiberglass saturation roller to remove trapped air. New design increases cutter head surface by 32% and increased quantity of chopped material between blade replacements by 33%. Our 1171 chopper gun is compatible with our #522 Gun Roving and #2293 24K Carbon Tow.
6K, 2 x 2 Twill Weave Carbon Fiber Fabric
10.9 oz/sq yd, 50" Wide, 0.017" Thick, 6K, 2x2 Twill Weave


This twill weave fabric features a tight weave and a cosmetically perfect 2x2 twill pattern. As a mid-weight carbon, it is a bit stiffer than 3K, meaning it is best used on flatter surfaces requiring less drapability. It retains the signature appearance that is highly desirable for modern composite parts in the auto, marine, and sporting goods industries. This fabric is frequently used for structural applications, offering improved economics to fabricators when compared to multiple layers of lighter fabrics.

Some considerations when creating composite parts with the #1073:
  • To maximize strength properties, use with an epoxy, like our System 2000 Epoxy Resin (#2000).
  • For added conformability, lay up the fabric at a 45-degree bias inside molds.
  • Once cut, twill fabrics are prone to unraveling due to the looser weave. Be sure to use our #1735-A Perfect Line Tape, or Dritz® Fray Check, #1713-A.

Fibre Glast is committed to ensuring that every roll of fabric we handle is First Quality and manufactured to the highest standards, so that you can expect the same properties and handling characteristics every time you order.

Vinyl Foam: Divinycell 4 lb. Density
Balanced Weight and Strength

Due to their outstanding structural properties, DIAB® closed cell vinyl foams are an excellent choice for sandwich core material in a composite part. When used as a structural sandwich core, 4lb vinyl foams strike a balance between strength and weight, while offering insulative properties. Vinyl foam sandwich cores significantly reduce weight and increase stiffness while maintaining or increasing strength compared to a thick reinforced laminate. 4lb foam is used extensively in marine (leisure, military and commercial) and automotive applications.

Applications vary for the different thicknesses we offer. Commonly used for vertical supports and walls, 3/8" thick foam offers additional strength and impact resistance to a composite laminate without adding significant weight. 1/2" thick foam offers significant strength to a part with a limited impact on overall weight. Applications for 1/2" vinyl foam include boat hulls, exterior panels, and other structural components. Many customers experiment with various thicknesses and densities of foam to find the correct balance between part weight and strength.

Vinyl Foams are compatible with all of our resins and can be easily thermoformed with a heat gun or oven. DIAB® Divinycell H60 4 Lb. Density, 32" X 48" Sheets.
KEVLAR<sup>®</sup> Tape
5 oz/sq yd, Various Widths, 0.0100" Thick, 17x17 Plain Weave


KEVLAR® tape is ideal for selective reinforcement of KEVLAR®, fiberglass, or carbon laminations and repairs. Its plain weave pattern matches our #2469 fabric and offers uniform strength and drapability for wrapping or laying in strips, particularly for applications of unique shape. They are ideally suited for marine and sporting goods applications. KEVLAR®, generally, is not suitable for applications that call for compressive strength.

KEVLAR® tape is called tape only for appearance and width—it is not adhesive backed. It is made to be used with a resin, like epoxy or vinyl ester. Finished edges make for ease in handling and keep them from unraveling. They make a great alternative to cutting strips from a larger piece of fabric.

Before starting your project with KEVLAR®, consider:
  • KEVLAR® is difficult to cut, sand, and machine. Consider a dedicated pair of serrated scissors, like our #1731-A.
  • Our KEVLAR® is not meant to be sewn.
  • Unused KEVLAR® should be stored away from UV light.


Fibre Glast is committed to ensuring that every roll of fabric we handle is First Quality and manufactured to the highest standards, so that you can expect the same properties and handling characteristics every time you order.
