Tiling can look hard at first. Still, a simple wall or a small-to-medium floor is very doable for a careful DIYer. You need the right tools, a flat surface, and enough time. This guide walks through the job in order, from measuring the room to sealing the grout. It also points you to the products we would use ourselves.

Tools and materials you’ll need

• Tile adhesive rated for your surface and tile type we recommend Gel-Tec S1 Flexible Tile Adhesive for most porcelain and ceramic jobs.
• Grout. Use sanded grout for wider joints and unsanded grout for narrow rectified joints.
• Notched trowel. Choose the size based on tile size, because larger tiles need a bigger notch.
• Tile spacers or a levelling clip system for large-format tiles.
• Manual tile cutter or wet saw. A wet saw helps a lot with thick porcelain.
• Spirit level, tape measure, and chalk line.
• Rubber grout float, grout sponge, mixing bucket, and paddle mixer attachment.
• Tile primer or sealant. This is useful for marble-effect or natural stone finishes.

Step one: prepare the room

Start by clearing the space. Then check the subfloor or wall surface. It must be flat, dry, clean, and sound. Any flex in a timber floor should be fixed before tiling, because movement can crack grout or lift tiles later.

Check the surface

Run a level over the area. If the surface dips or rises, fix that first. A good base makes the whole job easier. It also makes the finished tiles look much better.

Measure the room

Measure length and width. Then work out the total area. Add 10% for waste, and more if you plan a diagonal or herringbone layout. Our tile calculator can do this for you.

Step two: plan the layout

Dry-lay the tiles before any adhesive goes down. This shows you where cuts will land and helps you avoid narrow slivers at the walls. It also lets you check the pattern at full size.

Mark a straight line

Snap a chalk line through the centre of the room, or from the most visible doorway. This keeps the layout square. Most rooms are not perfectly straight, so this step matters.

Choose the pattern

Straight lay is the easiest choice. Brick bond gives a softer look. Herringbone adds movement, but it takes more care. Pick the pattern before you mix the adhesive.

Step three: apply adhesive

Mix Gel-Tec S1 to a firm, ridged consistency. Then spread it in small sections with a notched trowel. Work in areas you can cover before the adhesive skins over.

Keep the layer even

Press the trowel at the same angle each time. This gives a more even bed of adhesive. As a result, the tiles sit better and look flatter.

Back-butter large tiles

If the tile is large, add a thin skim of adhesive to the back of the tile too. This helps coverage and reduces hollow spots. It matters even more with large-format porcelain.

Step four: lay the tiles

Set each tile into the adhesive with a slight twist. Use spacers or levelling clips to keep the joints even. Check level as you go. Do not wait until the end, because small errors build up fast.

Cut the edge pieces

Measure each edge gap on its own. Do not assume every side is the same. Walls are often slightly out of square. A wet saw gives the cleanest edge on porcelain, especially with rectified tiles.

Work in small sections

Do not spread adhesive over the whole room at once. Work in short runs. That gives you more control and keeps the adhesive fresh.

Step five: grout the joints

Let the adhesive cure first. In many cases, that means waiting 24 hours. After that, mix the grout and press it into the joints with a rubber float. Work diagonally across the tiles so you fill the gaps fully.

Clean the surface

Wipe away excess grout with a damp sponge before it hardens. Rinse the sponge often. Keep the pressure light so you do not pull grout back out of the joints.

Seal where needed

Natural stone and some matt marble-effect tiles may need a sealant. Most glazed porcelain does not. Always check the product page before you skip this step.

Step six: finish and inspect

When the grout has cured, buff the surface with a dry cloth. Then check the joints for any pinholes or weak spots. Fix those before you move furniture back in. This final check saves time later.

Choosing the right adhesive and grout

When to call a professional

If your project includes any of the above, a pro may be the better choice. The same is true if the subfloor has movement or damage. On large-format porcelain, one mistake can be expensive. In that case, professional labour often pays for itself.

Aftercare and cleaning

Do not walk on a newly grouted floor for at least 48 hours. Also avoid harsh acidic cleaners on natural stone or marble-effect finishes in the first month. For daily cleaning, use a pH-neutral tile cleaner and a microfibre mop. That keeps both matt and polished porcelain looking fresh.
