Fiber Fusion Data Sheet



FIBER FUSION Product Data Sheet

FIBER FUSION waterproof uncoupling underlayment provides a fast, durable and cost effective solution for tile installation.

FIBER FUSION'S technology works by absorbing subfloor movements and reinforcing mortar; while the fabric allows for shearing movement to take place by separating the subfloor from the tile or natural stone.

FIBER FUSION is an ideal product for plywood substrates providing both reinforcement and water protection using a laminate water resistant fabric. FIBER FUSION is designed to keep their durability for years to come.

Applications

  • Over plywood or OSB subfloors
  • Prior to installing tile or natural stone
  • Over concrete
  • Over radiant heat flooring

Packaging

  • 60 square feet roll
  • 4 ft. width x 15 ft. length / 9 lb roll

Material & Storage Requirements

Deliver and keep materials in original packaging until ready to use.

Benefits

  • Crack isolation protection
  • Water resistant
  • Strengthens wood substrate
  • Easy to install
  • Light weight
  • High compressive strength
  • Increases tensile strength
  • Reinforcement for mortar
  • High point load strength

Physical Characteristics

A geometrically shaped roll with entangled net bonded to water resistant fabric.

Floor Requirements for Installation Instructions

WOOD

FIBER FUSION may be applied over both plywood and OSB flooring. The flooring must be structurally sound and built to code with movement joints placed in accordance to industry standards.

Joist

  • For a 16" o.c. joist, I-joist, or floor truss, use a minimum subfloor thickness of 5/8" (16 mm). Tongue-and-groove with a 1/8" (3 mm) gap between sheets.
  • For a 19.2" o.c. joist, I-joist, or floor truss, use a minimum subfloor thickness of 3/4" (19 mm). Tongue-and-groove with a 1/8" (3 mm) gap between sheets.
  • For 24" o.c. I-joist, or floor truss, use a double layer of plywood. Use a minimum subfloor thickness of 3/4"(19 mm) and an added layer of 3/8" (10 mm) subfloor as a second layer.

Substrate Preparation

  • Verify subfloor is properly fastened, structurally sound and built to code. Must comply to TCNA substrate requirements, defined in 2014 TCNA Handbook for Ceramic, Glass, and Stone Tile Installation.
  • Clear any dust, paint, oil, wax or possible mortar bond breaker.
  • Subfloor should be flat and even. Any leveling must be done prior to installing FIBER FUSION.

Thin-set Mortar and Grout

A modified thin-set in accordance to ANSI A118.14 and/or ANSI 118.11 may be used as well as unmodified thin-set mortar in accordance to ANSI A118.1 when installing FIBER FUSION.

Note: Modified Thin-set is Recommended. However, any thin-set or grout can be used with FIBER FUSION.

Waterproof

FIBER FUSION may be used as a waterproof product with additional installation instructions. Without these steps FIBER FUSION acts to protect the area from most water due to the water resistant fabric.

Note: Please See Waterproofing Installation Instructions.

CONCRETE

FIBER FUSION may be applied over any structurally sound concrete. It may be applied over concrete that is cracked or pre-stressed.

Requirements:

  • Slab must be structurally sound.
  • Must be free of wax, oil, dirt or any other bond breakers.
  • Must be flat and prepared prior to install of FIBER FUSION.
  • Assure the relative humidity level is within accordance to ASTM F2170 Standard test Method for Determining Relative Humidity in Concrete Floor Slabs. FIBER FUSION may help reduce some relative humidity with the permeability of the fabric.
  • Cracks in the concrete subfloor must exhibit in-plane movement only.

Thin-set Mortar and Grout

A modified thin-set in accordance to ANSI A118.14 and/or ANSI 118.11 may be used as well as unmodified thin-set mortar in accordance to ANSI A118.1 when installing FIBER FUSION.

Note: Modified Thin-set is Recommended. However, any thin-set or grout can be used with FIBER FUSION.

Movement Joints:

Movement joints must be installed in accordance with normal industry standards.

HEATED FLOORS

FIBER FUSION may be installed over electric thin mat or wire heating floor systems. Follow heated floor manufacturers instructions for the heated mat installation.

Preparation

For wood and concrete floors refer to the above flooring requirements. Prepare floor in accordance to the heating systems manufacturer. FIBER FUSION may be installed over the radiant heat mat in the same manner as it would be over a concrete or wood surface.

TOOLS

  • 1/4" or V- notch trowel for installing FIBER FUSION
  • Appropriate Thin-set Mortar
    • - 50 lb bag for 150-200 ft2 when installing FIBER FUSION
    • - 50 lb bag for about 30-40 ft2 when setting tile
  • Carpet knife
  • Tile float or roller
