How to Regrout Wall or Floor Tiles
Renew failed grout properly without damaging tile edges, and recognise joints or moisture problems that need more than cosmetic regrouting.
- Inspect the tiled area first. Loose tiles, movement, water penetration behind the finish or repeated cracking need diagnosis before replacing grout.
- Confirm the tile type and choose a grout compatible with the joint width, location and exposure. Wet areas, heated floors and natural stone can have product-specific requirements.
- Remove failed grout to a consistent useful depth using a hand tool or suitable powered grout-removal tool while protecting tile edges and waterproofing beneath.
- Vacuum dust and debris thoroughly and clean the joints as required by the grout manufacturer.
How to Tile a Wall: Preparation, Layout, Adhesive & Grout
Prepare a sound, flat background, plan the layout and fix and grout wall tiles without treating adhesive, joints or movement details as one-size-fits-all.
- Inspect the background before tiling. It needs to be sound, sufficiently flat, clean and suitable for the tile, adhesive and room conditions; active damp or movement needs diagnosis first.
- Plan the tile layout from controlled datum lines so rows stay level and obvious edges do not finish with avoidable tiny slivers.
- Choose an adhesive compatible with the tile material and size, background and exposure. Wet areas and specialist tiles can require a particular system or primer.
- Spread only a manageable area with the trowel/notch specified for the adhesive and tile, keeping the bed consistent rather than allowing a dry skin to form.
