1. Why Are Movement Joints Non-Negotiable?

Tiles and their substrates (e.g., concrete, cement board) expand and contract due to temperature changes, moisture fluctuations, and structural loading. Without adequate space to relieve this stress, pressure builds within the tiling system, ultimately causing:

• Tile tenting

• Grout cracking

• Tile fracture

2. Step-by-Step Installation Guide

Step 1: Planning & Layout
According to industry standards (e.g., ETAG 022, BS 5385), movement joints MUST be placed at:

• All structural joints and changes in substrate.

• Regular intervals: every 3-5 meters for walls, 6-8 meters for floors.

• Internal corners (where walls meet).

• Perimeters of door and window openings.

• (More frequent intervals are required for exterior applications).

Step 2: Substrate & Tile Preparation
During tile installation, a continuous, unobstructed gap (typically 5-10mm wide, as per engineering calculation) must be left at the planned joint locations. Ensure this gap is clear of tile adhesive and debris.

Step 3: Selecting the Correct Movement Joint System
A complete system comprises three components:

1. Backing Material: Insert a high-density, closed-cell polyethylene foam backer rod into the gap to control the sealant's depth and provide a backing surface.

2. Elastic Sealant: Use a high-quality, high-movement capability (±25% or more) polyurethane or silicone sealant designed for building materials. The width-to-depth ratio should follow manufacturer specs (often 1:1 or 2:1).

3. Metal Edge Trim Protection (Key Step): Install our professional metal movement joint profiles over the sealant or in place of wide-sealant-only solutions. They:

   • Protect the underlying sealant from abrasion, traffic, and UV degradation.

   • Provide a clean, straight, and aesthetically pleasing finish.

   • Distribute stress from foot traffic and movement, significantly extending the joint's life.

Step 4: Installation

1. Thoroughly clean the joint, ensuring it is free of dust and grease.

2. Install the backer rod to the recommended depth.

3. If using sealant alone, apply the sealant and tool it to a concave finish.

4. (Recommended Solution) Install our metal movement joint trim. These profiles often have anchoring legs that embed into the tile adhesive. Ensure the top of the profile is flush with or slightly below the tile surface.
