Tiling Guide: Wall & Floor Tiling in the North West
Everything you need to know before starting a tiling project — from choosing the right tiles and preparing the substrate to waterproofing, large-format installation and long-term maintenance.
Choosing the Right Tiles
Selecting the right tile is the foundation of a successful tiling project. Porcelain is the most popular choice for North West homes and businesses because it is dense, water-resistant and available in large-format marble, stone and wood-effect finishes. Ceramic offers an affordable option for kitchen splashbacks and feature walls, while natural stone such as travertine, limestone and slate brings character but demands sealing and ongoing maintenance. For bathrooms and wetrooms, large-format porcelain with a marble-effect finish creates a seamless, modern look with fewer grout lines and easier cleaning. Always choose a tile rated for its intended use — wall tiles are thinner and should never be used on floors, while floor tiles must carry a suitable PEI wear rating for foot traffic.
Substrate Preparation & Self-Levelling
A flawless finish starts beneath the tile. Proper substrate preparation is what separates a lasting installation from one that cracks or lifts. Before any tile is laid, the subfloor must be assessed for level, soundness and moisture. Timber floors may need overboarding with tile backer board to eliminate flex, while uneven concrete subfloors benefit from a self-levelling screed to create a perfectly flat surface — essential for large-format porcelain up to 1200x1200. Skipping this step leads to lipped tiles, hollow spots and premature failure. At Avenza Tiling we never compromise on preparation: every floor is cleaned, primed and levelled so the finished surface is true, flat and built to last.
Waterproofing & Wetroom Tanking
In bathrooms, shower areas and wetrooms, waterproofing is non-negotiable. Tanking systems — using liquid membranes or sheet membranes — seal the floor, walls and all junctions before tiling, preventing water from penetrating the substrate and causing rot, mould or structural damage. A correctly tanked wetroom routes water straight to the drain with the right falls, keeping the rest of the room dry. Grout alone is not waterproof; even epoxy grout will not stop water passing through the tile bed. That is why professional tanking, properly applied to clean, primed substrates and sealed at every corner, is the single most important step in any bathroom tiling project.
Large-Format Installation
Large-format tiles — 600x600, 600x1200 and larger — are increasingly popular for modern, seamless interiors, but they demand skill and the right equipment. Lipping between adjacent tiles must be kept to a minimum, which requires a flat substrate, full-bed adhesive and the use of levelling clips. Tiles this size also expand and contract with temperature, so movement joints and the correct flexible adhesive are essential, particularly over underfloor heating. When installed correctly, large-format porcelain delivers a premium, almost grout-line-free surface that suits open-plan kitchens, hallways and contemporary bathrooms across the North West.
Grout, Sealing & Maintenance
Grout choice affects both appearance and longevity. Epoxy grouts are highly water- and stain-resistant and ideal for wet areas, while cementitious grouts suit most domestic applications and should be sealed in bathrooms and kitchens. Matching grout to the tile colour creates a seamless look, while a contrasting grout highlights the tile layout and pattern. After installation, seal natural stone and cementitious grout to protect against staining, and re-seal periodically. Regular cleaning with a pH-neutral cleaner — avoiding acidic products on natural stone and grout — will keep tiled surfaces looking new for years.
