Assessment: Preparing Your Tiled Surface for Permeable Flooring

Thinking of installing a permeable flooring system over existing tiles? Proper assessment before starting is crucial to achieve strong adhesion and a long-lasting finish. Here’s how to evaluate your tiled base for the best results.

Check Surface Condition and Stability

Begin by closely examining your tiled area. Ensure that all tiles are well-bonded, flat, and free of visible cracks or movement. Loose, hollow-sounding or severely damaged tiles should be removed and repaired to prevent future failures.

Remove any broken or unstable sections.
Check for signs of underlying moisture or past water damage.
Confirm the tile surface is clean and free from oil, wax, or other contaminants.

Assess Adhesion and Drainage Potential

While permeable flooring systems like the Flowstone Kit are designed to manage water runoff, the substrate beneath your tiles still matters. Tiled surfaces generally offer little natural drainage, so it’s important to:

Confirm the existing substrate can support the intended load and traffic.
Roughen glossy or glazed tiles by mechanical means to improve resin or primer adhesion.
For outdoor areas, consider the drainage properties of what lies beneath the tiles, as trapped water may cause long-term issues.

Preparing for Installation

After assessment, preparation is key. Once repairs are made and the tiles cleaned, use the right primer or binder for your system. For instance, pairing washed pebbles with a suitable resin binder, such as the “Polirock” polyurethane binder for white stones, ensures an effective, attractive, and permeable result. Always follow step-by-step guidance from your kit instructions for optimal outcomes.
