DIY Carpet Installation Guide

Skip the Installer - Lay Premium Carpet Tiles Yourself

Traditional carpet needs a professional with power stretchers and tack strips. Modular Carpet tiles need you, a utility knife, and a free afternoon. Here's exactly how to do it.

What You'll Need

  • Utility knife with spare blades
  • Straight edge or T-square
  • Chalk line
  • Tape measure
  • Carpet roller (optional but recommended)
  • Short-nap paint roller or notched trowel (for adhesive)
  • Knee pads (for comfort)

Materials

  • Modular Carpet tiles (+ 10% extra for cuts/spares)
  • Pressure-sensitive carpet tile adhesive
  • Levelling compound (if needed)

Pro Tip: Order 10% more tiles than your calculation says. This covers edge cuts and gives you spares for future replacements.

1

Prepare Your Subfloor

A clean, level subfloor is the foundation of a beautiful carpet tile installation. The good news? Our breathable felt backing is compatible with most existing hard floors.

  • Sweep or vacuum the entire subfloor thoroughly
  • Fill any cracks, holes, or divots with levelling compound
  • Ensure the surface is dry (our breathable backing tolerates moisture-affected slabs, but standing water should be addressed)
  • Remove any existing carpet, underlay, or loose flooring material
  • Concrete, plywood, existing vinyl, and existing tile are all suitable subfloors

Run a straight edge across the floor to find high and low spots

Allow new concrete to cure for at least 28 days before installing

2

Apply Pressure-Sensitive Adhesive

Pressure-sensitive adhesive (PSA) is the secret to easy, repositionable installation. Unlike wet-set adhesive, PSA stays tacky permanently - so tiles can be lifted and repositioned even years later.

  • Pour adhesive and spread evenly with a short-nap roller or notched trowel
  • Work in manageable sections (about 3–4 metres at a time)
  • Allow adhesive to 'tack up' - it should feel sticky but dry to the touch (30–60 minutes depending on conditions)
  • The adhesive remains tacky indefinitely once dry - don't rush this step
  • Coverage: approximately 5–7 m² per litre

On hot days the adhesive tacks up faster; on cold or humid days it takes longer

Don't apply adhesive over dusty or oily surfaces - it won't grip

3

Lay Your Carpet Tiles

This is the satisfying part. Starting from the centre of the room, lay your tiles in an ashlar (brick-bond) pattern for a seamless broadloom look. Each tile presses firmly into the adhesive and grips immediately.

  • Find the centre of the room by snapping chalk lines between opposite walls
  • Start laying tiles from the centre outward
  • Use an ashlar (brick-bond) layout - offset each row by half a tile length (500 mm)
  • Check the arrows on the back of each tile - all arrows should point the same direction
  • Press each tile firmly into the adhesive with your hands or a carpet roller
  • Butt tiles tightly together - the seamless look depends on tight joins

Dry-lay a row first (without adhesive) to plan your cuts at the edges

Work outward in a pyramid pattern to keep everything square

4

Trim, Finish & Enjoy

The felt backing cuts cleanly with a standard utility knife. Trim edge tiles to fit, tidy up the perimeter, and you're done. Walk on your new floor immediately - no drying time required.

  • Measure edge tiles by flipping the tile upside-down against the wall
  • Score the backing with a sharp utility knife using a straight edge
  • Snap the tile along the score line for a clean cut
  • Press edge tiles firmly into adhesive
  • Replace furniture carefully - use felt pads on heavy items

Change utility knife blades frequently - a sharp blade makes cleaner cuts

Order 10% extra tiles for edge cuts and future replacements

Important Notes

  • Allow tiles to acclimatise in the room for 24 hours before installation
  • Room temperature should be between 18°C and 28°C during installation
  • Keep spare tiles from the same batch for future replacements
  • For best results, use a carpet roller after installation to ensure full adhesion
