Installation Guide

Mosaic Tile Installation Guide

At World of Mosaic, we supply high-quality mosaic tiles designed for kitchens, bathrooms, pools, and outdoor areas. Correct installation is essential to achieve the best appearance, durability, and long-term performance. This guide provides general installation advice for porcelain, marble, and glass mosaic tiles.

Important: We always recommend using a qualified professional tiler, especially for pools, wet rooms, and outdoor installations.

Before You Start

Check the Tiles

  • Inspect all mosaic sheets before installation
  • Ensure colour, size, and finish match your order
  • Install tiles from multiple boxes to avoid shade variation
  • Do not install damaged or faulty tiles

Once tiles are installed, claims for appearance-related issues cannot be accepted.

Surface Preparation

Proper surface preparation is critical.

  • Substrates must be clean, dry, level, and structurally sound
  • Remove dust, grease, paint, or loose materials
  • Repair cracks or uneven areas before tiling
  • For wet areas, ensure proper waterproofing is in place
  • External surfaces must be weather-resistant and fully cured

Suitable substrates include:

  • Cement backer boards
  • Rendered walls
  • Concrete floors
  • Tile backer boards

Adhesive Selection

Use the correct adhesive for your mosaic type and application:

  • Porcelain Mosaic: Flexible cement-based adhesive (C2 rated)
  • Marble Mosaic: White flexible adhesive to prevent staining
  • Glass Mosaic: White, highly flexible adhesive suitable for glass

For pools and outdoor areas, use waterproof and frost-resistant adhesives.

Always follow the adhesive manufacturer’s instructions.

Tile Installation

  1. Apply adhesive using a small-notched trowel (usually 3–6mm)
  2. Spread adhesive evenly over a manageable area
  3. Press mosaic sheets firmly into place
  4. Use a rubber float to ensure even contact
  5. Maintain consistent spacing between sheets
  6. Regularly check alignment and level

Avoid excessive adhesive between tile joints.

Cutting Mosaic Tiles

  • Use a wet tile cutter or mosaic tile nippers
  • Cut from the back of the sheet where possible
  • Take extra care with glass and marble mosaics
  • Wear appropriate safety equipment

Grouting

Allow adhesive to fully cure before grouting (usually 24 hours).

  • Choose a grout suitable for the tile material and environment
  • Use non-sanded grout for glass and polished marble mosaics
  • For pools and wet areas, use waterproof or epoxy grout
  • Apply grout diagonally across joints
  • Clean excess grout with a damp sponge before it dries

Sealing (For Marble Mosaic)

Natural stone mosaics should be sealed:

  • Apply a suitable stone sealer before and after grouting
  • This helps prevent staining and moisture absorption
  • Follow the sealer manufacturer’s guidelines

Porcelain and glass mosaics generally do not require sealing.

Aftercare & Maintenance

  • Avoid heavy use for at least 24–48 hours after installation
  • Clean tiles using pH-neutral cleaners only
  • Avoid harsh chemicals or abrasive cleaners
  • Reseal marble mosaics periodically if required

Special Applications

Kitchen Mosaics

  • Ensure splashback areas are heat-resistant
  • Allow adequate curing before exposure to water or steam

Bathroom & Wet Rooms

  • Waterproofing systems are essential
  • Use anti-slip options for floors

Pool Mosaics

  • Use pool-approved adhesives and grout
  • Allow extended curing time before filling the pool

Outdoor Mosaics

  • Ensure frost-resistant tiles, adhesives, and grout
  • Install only in suitable weather conditions
