How we do it
We sue specialised Sandblasting systems including automatic CNC sandblasters, Cabinet systems or Mobile onsite dustless blasters.
Couple that with ProBlast Sandblasting vinyl masking or PhotoMask Polymer Resist creating precision stencils with high point accuracy. The Photomasks allow for sharp detail at small sizes allowing fine detail work including great-looking photographic images.

What we can engrave
We can engrave any type of stone regardless of finish - Honed or exfoliated.
Granite, Marble, Quartz, Limestone, Basalt, Slate, Sandstone, Travertine, River Stone, and Stone Tiles. If it is not listed here we can probably engrave it.
We can engrave anything into stone such as text, logos, drawings, and photographic images.

How deep is the engraving?
We normally etch to about 1mm but can etch deeper upon request. 1mm is actually pretty deep even though it does not sound like it. As a general rule, you should not engrave deeper than the etching is wide.
Let’s say your font is about 2mm wide. If you etch to 3mm depth it can look distorted. We are experts at stone engraving and consider the best solution for your engraving needs.

The contrast effects of different coloured stone
When you etch into stone the colour of the etching is usually lighter than the surface. It comes out a frosted finish. If you have a dark stone the etching comes out lighter and contrasts nicely.
If you have a light coloured stone the etching comes out lighter and doesn't contrast with the stone surface and engraving can be hard to read. We recommend paint filling for light-coloured stone.

Coating stone etching
We use quality outdoor-grade epoxy paints for paint filling your projects when paint filling is required. We can PMS colour match any colour. We lay a sealer down first to ensure a good bond.
Another option available is to apply a slip-rated sealer onto a wide area of stone etching for when the stone is going to be walked on.
Gold Leaf Gilding is also an option (albeit and expensive option)

How big a piece can we engrave?
Pretty much any size can be etched as long as we can move it. We don’t use cranes, just forklifts and strong trolleys.
Our sandblasting equipment size limitation is about 1200mm wide buy almost any length. Sizes larger than 1200mm wide can still be etched with our portable sandblasting equipment
