Check it suits your joints

Two minutes here saves a return. The Grout Buster 3000 is built for straight grout lines on standard-to-wide joints - confirm your joint width and material before you buy.

✓ Works with
✓Cement / cementitious grout - sanded and unsanded
✓Epoxy grout - slower, in short sections, with a heavier blade
✓Standard-to-wide joints (roughly 2-6mm+)
✓Floor and wall tiles - long straight runs shine
✓Bathroom, kitchen and commercial re-grouts
✓Mortar, grout, epoxy and loose concrete on brick and masonry
✕ Does not suit
✕Hairline / very narrow joints under ~1.5mm - use hand tools
✕Mosaic and small-format tiles with tight, uneven joints
✕Delicate tiles - glass, soft stone, hand-painted or already chipped
✕Silicone or caulk in corners - that isn't grout, use a silicone remover
✕Internal corners and tight curves - finish these by hand
i Working around corners, curves or mosaics? A straight blade can't reach cleanly - stop short and finish by hand with a grout pick. Call us if you're not sure it suits your joints.

Replace the blade, not the machine

When cutting slows or the blade starts running hot, swap it for a fresh diamond blade. Match the thickness to your joint - 1.2mm for fine joints through to 2.7mm for heavy-duty grout and epoxy.

Frequently asked questions

  • Will it damage my tiles?

    Not if the blade is narrower than the joint and the stainless guide wheels keep it centred on the grout. Work a shallow pass first and ease off near edges. Chips happen when the blade wanders onto the glaze - the guide wheels are designed to stop exactly that.

  • Can it remove epoxy grout?

    Yes, but epoxy is much harder than cement - go slower, work in short sections to avoid heat build-up, and use a thicker heavy-duty blade (the 2.7mm).

  • Does it handle cement grout?

    Yes - that's its ideal material, sanded or unsanded. It gives the fastest removal and the longest blade life on cementitious grout.

  • How deep does it cut?

    Up to 13.5mm maximum. Rake to at least around 3mm - deeper for crumbling or mouldy grout - so the new grout keys into a firm base.

  • How does it control dust?

    It has an integrated vacuum and a dust collection bag that capture debris at the cut. For silica compliance, still wear a P2 respirator, pair it with a suitable dust extractor where required, and follow your site's WHS requirements.

  • How long does the blade last?

    Diamond blades outlast carbide many times over on grout. Replace the blade when cutting slows or heat and vibration rise. Replacement diamond blades are available separately.

  • Can I use it on both walls and floors?

    Yes - both. Floors and long straight runs are where it's fastest.

  • What joint widths does it suit?

    It's best on standard-to-wide joints (roughly 2-6mm+). It's too wide for hairline or mosaic joints under about 1.5mm - use hand tools there.

  • Can it follow curves or get into corners?

    Straight lines, yes. Tight curves, mosaics and internal corners are better finished by hand with a grout pick - a straight blade can't reach cleanly.

  • Can I remove silicone with it?

    No. Silicone in corners and change-of-plane joints isn't grout - remove it with a knife or silicone remover, never a grout blade.
