Tiling a Floor on Floorboards: A Comprehensive Guide

Embarking on a tiling project on existing floorboards can transform your space, adding durability and style. However, it's crucial to understand the unique challenges and best practices involved in this process. This guide will walk you through the steps of tiling a floor on floorboards, ensuring a professional finish that lasts.

Understanding the Surface: Floorboards vs. Concrete

Floorboards present a different substrate than concrete or plywood. They're less stable, can shrink and expand with humidity changes, and may not be perfectly level. Therefore, it's essential to prepare the surface correctly and choose the right tiles and adhesive.

Choosing the Right Tiles and Adhesive

Opt for smaller tiles (600mm x 600mm or smaller) as they're less affected by movement and easier to install. Porcelain or ceramic tiles are suitable, but avoid natural stone tiles, which can crack due to movement. Choose a flexible, high-performance adhesive designed for wooden substrates, such as a cement-based adhesive with added polymers.

Preparation: Inspect and Prepare Your Floorboards

Before you start, inspect your floorboards for any damage, rot, or squeaks. Repair as necessary. Ensure the floor is clean, dry, and free of any contaminants that could hinder adhesion. If the floorboards are not level, consider using a self-levelling compound to create a smooth surface.

Ventilation and Safety

Proper ventilation is crucial when working with adhesives and grouts. Ensure your workspace is well-ventilated, and consider using a respirator. Always wear safety glasses and gloves to protect against debris and chemicals.

Laying the Tiles

Start tiling from the center of the room, working outwards. This helps to minimize waste and ensures a balanced layout. Use a tile cutter or wet saw to cut tiles to fit around obstacles like door frames and pipes.

Spreading the Adhesive

Spread the adhesive evenly across the floorboards using a notched trowel. Hold the trowel at a 45-degree angle to the floor and use the notched edge to create grooves in the adhesive. This helps to create a better bond with the tiles.

Laying the Tiles

Press the tiles firmly into the adhesive, using a slight twisting motion to ensure full contact. Leave a 2mm gap between tiles for grouting. Use tile spacers to maintain even gaps. Allow the adhesive to cure according to the manufacturer's instructions before proceeding with grouting.

Grouting and Sealing

Mix the grout according to the manufacturer's instructions. Apply the grout to the tiles using a rubber float, working diagonally to the tiles to force the grout into the gaps. Allow the grout to set slightly, then clean the tiles with a damp sponge. Once the grout is completely dry, apply a suitable sealer to protect the tiles and grout.

Post-Installation Care

Allow the tiles and grout to cure completely before subjecting them to heavy traffic or moisture. Follow the manufacturer's guidelines for cleaning and maintenance to ensure the longevity of your tiled floor.

Regular Inspections

Regularly inspect your tiled floor for any signs of movement, cracking, or lifting. Address any issues promptly to prevent them from becoming more significant problems.
