Tile Quick Tips

Keep these essentials in mind when shopping for your tiles.

Make your selection early and check stock availability.

Most tiles are priced per metre unless specified otherwise. Purchasing, however, is per carton.

Have your measurements handy. Add 10–15% for cutting and wastage. Keep a box of tiles for spares.

Ask if sealing is required and if there are any tile care recommendations.

Check if there are any delivery costs. Sometimes there’s a freight charge on products coming from suppliers.

Research PEI ratings and the MOHS scale and assess the product’s suitability for the project.

Tile Types

Tiles are manufactured from various materials and each type has its own benefits. Consider your personal style, budget and functionality requirements when selecting.

Glazed porcelain marble-look tiles

Glazed Porcelain

Much harder and more wear-resistant than non-porcelain ceramic tiles, making them suitable for any application from light traffic to the heaviest residential and light commercial traffic.

Full bodied porcelain bathroom tiles

Full Bodied Porcelain

Colour throughout the entire tile body, not just on the surface. This makes chips and scratches less visible and is ideal for high-traffic commercial and residential areas.

Handmade ceramic wall tiles

Ceramic & Handmade

Typically used for wall applications and lighter traffic areas. Handmade tiles offer unique character with slight variations in colour and texture that add warmth and personality.

Natural stone tiles in kitchen

Natural Stone

Includes marble, travertine, limestone and granite. Each piece is unique with natural variations. They typically require sealing but offer unmatched natural beauty.

Green Moroccan zellige decorative tiles

Decorative & Mosaic

Mosaics, feature tiles and patterned designs add character and visual interest. Perfect for splashbacks, feature walls, bathroom niches and borders.

Rectified porcelain tiles in luxury bathroom

Rectified

Precision-cut after firing so that all tiles are exactly the same size with perfectly straight edges. Allows for narrower grout joints and a more seamless, contemporary look.

Always remember the golden rule: a floor tile can be used on a wall, but never use a wall tile on a floor.

Understanding Ratings

These industry standards help you choose the right tile for the right application.

PEI Ratings

The Porcelain Enamel Institute scale determines wear expectations for ceramic tiles.

  • PEI 1 Wall tiles only, no foot traffic
  • PEI 2 Light foot traffic (bathrooms, bedrooms)
  • PEI 3 Light to moderate traffic (residential areas)
  • PEI 4 Moderate to heavy traffic (all residential, light commercial)
  • PEI 5 Heavy foot traffic (commercial, high-traffic areas)

Slip Ratings

Indicates how slip-resistant a tile is when wet. Important for outdoor areas, bathrooms and pool surrounds.

  • R9 Minimal slip resistance (dry internal areas)
  • R10 Normal slip resistance (bathrooms, kitchens)
  • R11 Good slip resistance (laundries, wet areas)
  • R12 High slip resistance (outdoor, pool areas)
  • R13 Very high slip resistance (commercial wet areas)

MOHS Hardness

Rates the hardness of tile surfaces from 1 (softest) to 10 (hardest).

  • 1–3 Soft (not suitable for floor use)
  • 4–5 Moderate (light residential use)
  • 5–6 Medium (standard ceramic tiles)
  • 7–8 Hard (porcelain tiles, most applications)
  • 9–10 Very hard (heavy commercial, rare in tiles)

Tile Calculations

Arming yourself with all the information you need when you get to the tile store is the first place to start. You should have a clear idea of the area you wish to tile and the amount of foot traffic it will be exposed to.

How to Calculate How Many Tiles You Need

  1. Measure the area — Measure the length and width of each area to be tiled in metres.
  2. Calculate square metres — Multiply the length by the width to get the total area in m².
  3. Add wastage — Add 10–15% to your total to allow for cutting, breakage and future spares.
  4. Check carton coverage — Tiles are sold by the carton. Divide your total m² by the carton coverage to determine how many cartons you need, rounding up.

Selecting a Tiler

Choosing the right tiler is just as important as choosing the right tile. Here are some tips to help you find a qualified professional.

1. Qualifications & Experience

Find out what qualifications and experience the tiler has and ask for their BSA number.

2. Written Quotations

Knowing the total cost up front makes it clear what you’re spending. Clarify any ambiguity before agreeing to proceed.

3. Compare Quotations

Get multiple quotes, but remember that tiling is a long-term investment and the lowest price may not give the best result.

4. References

Most tilers are happy to let you contact recent customers to verify the quality of their work.

5. Trust Your Instincts

Go with the tiler that gives you confidence they will do a professional job.

6. Key Questions to Ask

  • Can you easily get a hold of the tiler?
  • Did the quotation cover all the work?
  • Were they punctual and reliable?
  • Did they appear keen to do the work?

Cleaning & Maintenance

Ceramic tiles are a practical, low-maintenance flooring material. However, it is important to clean them regularly so that dirt doesn’t build up. Your number one enemy is dirt — trapped dirt can be very abrasive, and sand and gritty dirt is likely to damage any tiled surface.

General Care Tips

  • Use a mat or rug at the entrance to doorways to reduce dirt tracking.
  • Sweep or vacuum regularly to remove loose dirt and grit.
  • Mop with warm water and a mild, pH-neutral cleaner.
  • Avoid harsh chemicals, steel wool or abrasive pads.
  • Clean up spills promptly to prevent staining, especially on natural stone.
  • Reseal natural stone tiles periodically as recommended by the manufacturer.

Grout Haze & Residue

After installation, a light haze from the grouting process may remain on the tile surface. This is normal and can usually be removed with a grout haze remover available from your tile retailer. Always test on a small area first and follow the product instructions.
