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.
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
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
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
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
