Think Fiberglass is a family-run company with over 25 years of hands-on experience in fiberglass waterproofing, repair, and fabrication. From showers and decks to pools, ponds, and industrial tanks, we’ve built a reputation for doing things once and doing them right.

We specialize in waterproofing services for showers, decks, and pools, as well as custom fiberglass fabrication and restoration. We also offer our proprietary FyberLok waterproofing kits, a ready-to-use system for builders and DIY installers.

We service the Tri-State area & more (NY, NJ, CT, MA, PA) and work with contractors and builders nationwide through our FyberLok product line.

We’ve been working with fiberglass for over two decades — perfecting the process, materials, and techniques that make our system the strongest in the industry.

FyberLok is a proprietary waterproofing system engineered by Think Fiberglass. It’s the same proven leak-free technology Think Fiberglass has been using to perfect showers, balconies, pools, ponds & more — now available in a ready-to-use kit for showers.

Each kit includes premium FyberMat, Proprietary resin & hardener, gloves, and mixing tools — all pre-measured for your project size. You also get exclusive access to step-by-step video tutorials and installation support.

• Standard: 20–40 sq. ft.
• Plus: 40–60 sq. ft.
• Deluxe: 60–80 sq. ft.
• Ultimate: 80–100 sq. ft.
  Each kit is sized to fit common shower footprints with extra material for overlap and peace of mind.

Membranes and coatings sit on the surface — FyberLok becomes the surface. The FyberLok System chemically bonds to the structure, forming a permanent, seamless waterproof shell that can’t peel, bubble, or fail at seams.

No, if you can paint a wall, you can apply FyberLok. The kit includes detailed instructions and QR-code access to private videos that guide you through each step. Most installs are complete in a few hours.

Depending on temperature and humidity, FyberLok fully cures within 12-24 hours and can be tiled or top-coated the next day.

FyberLok bonds to plywood, concrete, cement board, and certain foam substrates. It’s compatible with most modern building materials and doesn’t rely on primers or adhesives.

We don’t use membranes or roll-ons that fail over time. Our fiberglass systems create a structural, watertight shell bonded directly to your substrate — a system proven through thousands of leak-free installs.

Most residential showers or decks are completed in 1 day. Larger or multi-surface projects may take longer depending on prep and scope of the project.

Yes, fiberglass can be applied over concrete, cement board, or plywood — and we can also restore or reinforce existing fiberglass systems for long-term protection.
