How FyberLok Works
FyberLok is a hand-applied waterproofing system beneath tile.
It covers the prepared shower floor, lower surrounding walls, curb and built-in features, and connects to the drain. Think Fiberglass brings more than 25 years of fiberglass installation experience to the system.
The System
FyberMat™ is the fiberglass reinforcement used with the system.
FyberLok™ Part A and Part B liquid components saturate the reinforcement to form the waterproofing layer over the prepared shower.
FyberFil™ Powder is used in preparing corners and transitions. Follow the preparation and application videos included with your kit.
What Happens In The Shower
The shower must be prepared first, including the final mud pitch. FyberLok waterproofs the prepared surfaces; it does not create the slope.
Reinforcement is applied and saturated over the floor, lower walls, curb and planned features. Overlaps bond together. The drain connection needs to be planned before application.
FyberLok is typically tile-ready in 12–24 hours, depending on temperature and site conditions. Follow the Install Portal guidance before tiling.
Waterproofing Beneath the Tile
The finished tile covers the hand-applied waterproofing. FyberLok follows the shower layout, including the lower walls, curb, seats and other planned features.
Preparation, construction stability, application and the drain connection all matter. Review the Shower Layout Guide and the Install Portal steps before starting.
Good to Know
Prepared mortar, cured concrete, sound and dry wood or plywood, cement-based backer boards and existing cured fiberglass may be suitable. Confirm the specific board and preparation requirements with us first.
FyberLok connects to a standard three-piece clamping drain. Linear-drain arrangements need a review of the connection before ordering. Use a thinset suited to the prepared fiberglass surface; the Install Portal includes our recommendations.
