A Step by Step Guide to installing carpet tiles

Carpet tiles are one of the easiest floor coverings to fit yourself. There is no need for underlay, no awkward wall-to-wall stretching, and very little specialist kit. Whether you are refreshing a busy office, kitting out a retail space or laying a home office floor, a bit of care and preparation will give you a professional, hard wearing finish.

Follow the steps below and you will have your carpet tiles down in an afternoon.

What you will need

Before you start, gather a few basic tools:

• Tape measure
• Chalk line or pencil and a straight edge
• Sharp utility knife with a fixed blade
• Metal ruler or steel straight edge
• Double sided carpet tape, or carpet tile tackifier adhesive for larger areas
• A vacuum cleaner or brush for cleaning the subfloor

For bigger commercial areas, tackifier adhesive is the better choice. It holds the tiles firmly in place while still letting you lift and replace individual tiles later on.

Step 1: Prepare the subfloor

A good floor starts with a clean, dry and level base. Carpet tiles will sit directly on concrete, screed, timber or stone, so there is no need for underlay.

Sweep or vacuum the whole area to lift any dust and grit. Remove any existing carpet, underlay or floor covering completely. If old carpet has been glued down, score it into strips with a hook blade and lift it away.

Deal with any problems before you lay a single tile. Seal damp floors with a suitable damp proof sealer, and fill dips or damage with a self levelling compound. Time spent here pays off in the finish.

Step 2: Acclimatise the tiles

Carpet tiles need time to settle to room temperature before fitting, especially in colder months. Tiles delivered on a cold day can arrive chilled, and laying them straight into a warm room can cause them to expand and lift at the edges.

Take the tiles out of their boxes and stack them loosely around the room, allowing air to circulate between them. Leave them for at least 24 hours before you begin. Handle them carefully so you do not knock the corners.

Step 3: Find the centre and plan your layout

Working from the centre of the room gives the most balanced result and keeps your cut tiles even around the edges.

Measure the length and width of the room, then mark the midpoint of each wall. Snap a chalk line between the marks so the two lines cross at the centre. This gives you a clean starting cross to work from.

Before committing, dry lay a row of tiles in each direction from the centre. Check how the tiles fall at the walls. You are aiming for at least half a tile at the perimeter, so nudge your centre point if you end up with a thin sliver on one side. Never start against a wall with a full tile, as you can be left with an awkward narrow cut opposite.

Step 4: Choose your pile direction

Look at the back of each tile and you will see directional arrows showing the pile. How you lay them changes the look of the finished floor.

• Monolithic: all arrows point the same way. This hides the joins and gives the appearance of a continuous, traditional carpet.
• Quarter turn: each tile is turned 90 degrees to its neighbour. This creates a subtle checkerboard of light and dark shades and a more contemporary look.

Neither method affects how the tiles wear, so choose the effect you prefer. This is also where you can get creative with borders, patterns or inset shapes using different colours.

Step 5: Lay the tiles

Start at your centre cross and work outwards with whole tiles, building up the floor one quarter at a time.

If you are using tackifier adhesive, read the instructions on the tub first. It goes on like a thin, off white glue and can be rolled or brushed onto the floor. The key point is to wait until it turns from white to completely clear before laying tiles onto it. Laying too soon can bond the tiles permanently and stop you lifting them later.

If you are loose laying instead, run double sided carpet tape along the centre rows and around the perimeter to stop the tiles shifting as you work.

Butt each tile up tight against the last, taking care not to trap any pile in the joints. Keep checking as you go that the tiles are square and tight, as a loosely fitted floor can creep and open up over time. As a rule of thumb, do not loose lay more than around 100 tiles in a single room without adhesive.

Step 6: Cut the edges

Once all the whole tiles are down, turn to the perimeter and any cuts around pipes or fittings.

Measure each gap and mark the cut on the back of the tile. For pipes and awkward shapes, a profile gauge or a card template makes light work of it. Always cut from the back, and keep your fingers clear of the blade.

To cut, score the back two or three times with a sharp knife, then snap the tile like plasterboard. Run the knife along the fold to release the pile cleanly. If the blade clogs, wipe it with a little white spirit on a cloth.

Step 7: Finish and maintain

When every tile is laid and cut, give the whole floor a final vacuum to clear any debris from fitting. Walk the room and check the tiles are still tight and aligned.

To keep your carpet tiles looking their best:

• Vacuum regularly to lift dirt before it settles into the pile.
• Blot spills straight away with a damp cloth rather than rubbing them in.
• Use a suitable carpet cleaner for stains, and avoid bleach or petrol based products.
• Keep a few spare tiles back. One of the biggest advantages of carpet tiles is that you can swap out a damaged tile in seconds rather than replacing the whole floor.
