Some clients specify unique designs that include motifs, logos or custom designs.

Sophisticated designs can be cut commercially using laser or water jet technology.

But it is also possible for a skilled installer to cut many designs by hand on-site.

You should always lay out the tiles in a dry run before applying the adhesive, especially when the design is complex.

This will let you make sure that each tile is in the right place before you stick it down.

It also helps you to ensure that the surrounding tiles are cut correctly and fitting properly around the motif.

Computer generated plans

Complex designs are generally developed with the aid of a computer-generated plan.

If you haven't been given a copy of the plan, ask the client or architect to supply a copy so you can take it to the jobsite for reference.

As you carry out the installation, re-check the details constantly to make sure the patterns are being laid exactly as specified.

Scribing a circle

To scribe a large circle in carpet tiles, you will need some form of marking gauge that can be fixed at the centre point and rotated around the radius of the circle.

This could be a piece of timber or even vinyl flooring, as long as it will keep its shape and not stretch.

Fasten one end of the marking gauge to the subfloor floor with a concrete nail (or screw, if the subfloor is timber).

Insert a scribing pin or knife (such as an X-acto knife) into a hole at the other end, measured to the precise length of the radius.

Rotate the marking gauge around the arc of the circle.

Cut the tiles from the back with a utility knife and dry lay the pieces in position to check the fit.
