Tiling Basics: Foundation Skills for Quality Work

Tiling is a skill that takes practice to master, but understanding the fundamentals helps whether you're learning or instructing others.

Surface Preparation

Good tiling starts with surface prep:

• Surfaces must be flat, clean, and stable
• Prime porous surfaces
• Use tile backer boards in wet areas
• Check walls are plumb and square

Planning the Layout

Think before sticking:

• Find the centre of the area
• Dry-lay tiles to check layout
• Avoid thin slivers at edges
• Symmetry usually looks better

Setting Out

1. Mark vertical and horizontal centre lines
2. Use a batten to establish first row level
3. Work from centre outward
4. Check levels constantly

Adhesive Selection

• Ready-mixed: Convenient for walls
• Powdered: Better bond, essential for floors
• Flexible: For movement-prone substrates
• Rapid-set: When you need to grout quickly

Applying Adhesive

• Use correct notched trowel size
• Apply at 45-degree angle
• Back-butter large or heavy tiles
• Only spread what you can tile before it skins

Cutting Tiles

Different cuts need different tools:

• Manual cutter: Straight cuts in ceramic
• Wet saw: Accurate cuts in any tile
• Grinder: Complex shapes and angles
• Hole saw: Circular cutouts

Grouting

• Wait until adhesive has set
• Mix grout to thick paste consistency
• Force into joints with float at 45 degrees
• Clean excess before it dries hard
• Shape joints with profiler or finger

Common Mistakes

• Insufficient adhesive coverage
• Not using spacers (or using wrong size)
• Rushing and losing level
• Grouting too soon
• Not sealing around baths and trays

Finishing

• Seal grout lines in wet areas
• Use silicone at corners and junctions
• Clean tiles thoroughly when complete
• Wait before exposing to water
