Find the Right Repair Product

Search by Material, Brand, or Repair Type

Use focused search terms such as epoxy putty, fairing compound, fiberglass cloth, reinforced filler, release fabric, plastic spreader, Awlfair, Interlux fairing, or West System epoxy.

Repair Planning

Choose the Product Around the Job, Not Just the Surface

Fiberglass repair can involve grinding, drying, cleaning, laminating, filling, fairing, sanding, priming, and finishing. Structural areas usually need reinforcement, while cosmetic areas may only need filling and fairing.

Mixing & Compatibility

Keep Systems Matched

Two-part products must use the correct base, converter, hardener, or catalyst. Check mix ratio, working time, cure time, temperature range, sanding window, and whether the product is meant for bonding, filling, fairing, or finishing.

Epoxy Hardener Fairing Converter Mixing Cups Spreaders
01

Prep Matters

Remove loose material, clean the area, dry the laminate, and sand or grind as needed before applying repair products.

02

Reinforce When Needed

Cracks, holes, tabbing, corners, and structural repairs may need cloth, mat, tape, or layered reinforcement.

03

Fair Before Finish

Use fairing compound to shape and smooth repaired surfaces before primer, paint, gelcoat, or final finishing.

Tools & Prep Supplies

Get the Supporting Supplies Before the Resin Is Mixed

Good fiberglass work depends on preparation and timing. Have spreaders, cups, rollers, sandpaper, masking supplies, gloves, cleaning supplies, and release materials ready before mixing resin, filler, or fairing compound.

Plastic Spreaders Mixing Cups Fiberglass Rollers Sandpaper Release Fabric
Before mixingConfirm the product system, mix ratio, working time, tools, surface prep, and environmental conditions.
During applicationWork cleanly, wet out reinforcement correctly, remove trapped air, and avoid mixing more product than you can use in time.
After cureSand, shape, inspect, fill low spots, clean dust, and continue with primer, paint, gelcoat, or finish work.

Resins & Fiberglass FAQ

Choosing Repair Materials

What is the difference between filler and fairing compound?

Fillers are often used to rebuild, fill voids, or add strength. Fairing compounds are used to smooth and shape a surface before sanding, priming, and finishing.

When should fiberglass cloth or mat be used?

Use reinforcement when the repair needs strength, spans a crack or hole, supports a structural area, or ties surfaces together. Cosmetic filling alone is not enough for many damaged areas.

Why do two-part products need matching components?

Two-part materials rely on the correct base, converter, hardener, catalyst, or mix ratio. Mismatched components can affect cure, strength, sanding, and adhesion.

What should be ready before mixing resin or filler?

Have the surface prepared, tools laid out, spreaders, rollers, cups, gloves, masking, abrasives, and cleanup materials ready before mixing so the product can be applied within its working time.
