Before you start

Prepare for a clean installation.

  • Check the base and layout

    Confirm the stone, tile or paver is 30–40 mm thick and the planned grout joint is 3 mm. Prepare a clean, flat, level base for the chosen installation.

  • Use the right adhesive

    Choose adhesive or bedding material suited to the installation. Apply it with the appropriate trowel, following the manufacturer’s instructions.

  • Have compatible wedges ready

    Use a compatible Regular Wedge where suitable, or the 30 mm Stone & Paver Wedge setup where the extra height is needed. Confirm the fit against your material thickness before laying.

Using the product

Place. Tighten. Remove.

Follow the three stages for your clip and compatible wedge.

  1. Place the clips and adjoining pieces — 3 mm stone clips · 30–40 mm

    Place the clips and adjoining pieces

    Set the first piece firmly, then slide the clip base under its exposed edge. Keep the upright part of the clip at the joint.

    Position the adjoining piece against the clip so the base sits beneath both edges. Check joint spacing as you continue.

  2. Insert and tighten the wedges — 3 mm stone clips · 30–40 mm

    Insert and tighten the wedges

    Push a compatible CLIP-IT® wedge through the clip opening to hold adjoining edges in alignment.

    Use a compatible Regular Wedge where suitable, or the 30 mm Stone & Paver Wedge setup where the extra height is needed. Confirm the fit against your material thickness before laying. Check adjoining surfaces as you tighten the compatible wedge.
    Example shown: 35 mm material with a Regular Wedge.

  3. Let the installation cure, then remove — 3 mm stone clips · 30–40 mm

    Let the installation cure, then remove

    Wait until the adhesive or bedding material has cured, following the manufacturer’s curing instructions.

    Remove the cured clips along the grout line. The DE-CLIP-IT Hammer can knock these larger clips off, but its slotted end does not fit over them. Recover the wedges for reuse.

A few useful answers

Get the details right.

Material thickness, wedge fit and clip removal.

What do 3 mm and 30–40 mm mean?

3 mm is the grout joint spacing. 30–40 mm is the thickness of the stone, tile or paver the clip is designed to suit.

Which wedge should I choose?

Use a compatible Regular Wedge where suitable, or the 30 mm Stone & Paver Wedge setup where the extra height is needed. Confirm the fit against your material thickness before laying.

Does the hammer slot fit these clips?

No. The slotted end does not slide over 3 mm 30–40 mm Stone Clips. Use the tool as a hammer to knock off cured clips along the joint.

When can I remove the clips?

After the adhesive or bedding material has cured. Follow its manufacturer’s curing instructions; there is no single curing time for every product and job.

Why is a clip not breaking cleanly?

Excess adhesive around the clip legs can interfere with removal. Keep that area clear during laying, allow curing, and remove along the grout line. Contact CLIP-IT® if a clip remains stuck.

Can the wedges be reused?

Yes. Recover the compatible wedges after clip removal and keep them for the next installation. The clips are designed to break at the base during removal.
