TI-ProBoard Underlayment for Exterior Deck Installations
Step-by-Step TI-ProBoard Installation Video Guide
This installation video demonstrates how TI-ProBoard structural composite underlayment is installed for exterior tile deck systems, rooftop terraces, balconies, and elevated outdoor tile applications.
TI-ProBoard is designed to create a durable tile-ready substrate that installs directly over joists without requiring traditional plywood decking or additional subfloor layers.
Exterior Tile Deck Installation System
TI-ProBoard helps simplify exterior tile deck construction while creating a strong and stable surface for porcelain tile, ceramic tile, natural stone, and outdoor flooring systems.
Popular applications include:
- Exterior tile decks
- Balconies and rooftop terraces
- Outdoor entertainment areas
- Walkways and elevated decks
- Poolside tile installations
- Commercial exterior flooring systems
The low-profile system design helps reduce overall floor height while improving installation efficiency and long-term durability.
Direct-to-Joist Structural Underlayment
TI-ProBoard installs directly onto deck joists, creating a stable 3/8" structural substrate without the need for traditional wood decking or cement backer boards.
This installation method helps:
- Reduce installation complexity
- Lower overall assembly height
- Improve moisture resistance
- Create durable tile-ready surfaces
- Simplify exterior deck construction
Interior Floor Applications
TI-ProBoard may also be used for interior tile flooring applications installed directly over floor joists.
With a total assembly height under 1 inch when combined with standard tile installations, TI-ProBoard helps create smoother transitions between tiled surfaces and adjacent flooring materials.
This lower-profile installation method can help minimize height differences compared to traditional plywood and subfloor assemblies.
