Cutting brick slips is one of those jobs that looks straightforward but can quickly go wrong if the wrong method is used. Brick slips are designed to look like full bricks, which means their texture, density and finish need to be respected during cutting. Get it right, and the finished wall looks seamless. Get it wrong, and chipped edges or uneven cuts can undermine the entire installation.
The most reliable method for cutting brick slips is using a wet tile cutter fitted with a diamond blade. This approach offers the best balance of accuracy, control and finish, especially when working with brick-faced materials rather than ceramic tiles. The continuous flow of water keeps the blade cool, reduces dust and prevents the brick from overheating and cracking during the cut.
Dry cutting tools, such as angle grinders, are often tempting because they’re quick and widely available. However, they come with drawbacks. Brick slips are more brittle than standard masonry, and the vibration from a grinder can cause chipping along the face. Dry cutting also produces fine brick dust, which is messy, hazardous to inhale and more likely to stain the surface of lighter-coloured slips. A wet cutter avoids these issues almost entirely.
Preparation is key before making the first cut. Brick slips should be measured carefully and marked using a pencil or chalk line rather than a marker that could bleed into the brick face. It’s worth double-checking measurements before cutting, particularly around sockets, corners and returns, where small inaccuracies are far more noticeable.
When using a wet tile cutter, patience matters. Forcing the slip through the blade increases the chance of breakage or rough edges. A slow, steady feed allows the blade to do the work, producing a clean cut that blends naturally once the slip is installed and pointed. This is especially important for cut edges that will remain visible, such as external corners or feature details.
For corners, many installers prefer to mitre brick slips at 45 degrees using the wet cutter rather than using pre-formed corner pieces. When done accurately, this creates a sharp, realistic edge that closely mimics traditional brickwork. The wet cutter’s precision makes this possible, while dry methods often struggle to achieve consistent angles.
After cutting, it’s good practice to lightly smooth any sharp edges with a fine sanding pad or rubbing stone. This doesn’t alter the appearance of the brick but removes fragile points that could chip during installation. Care should be taken not to overwork the surface, as brick slips are valued for their natural texture.
Ultimately, the best cutting method is one that protects the integrity of the brick slips. A wet tile cutter may take slightly longer to set up, but the results speak for themselves. Clean cuts, minimal waste and a professional finish all contribute to a brick slip wall that looks intentional, balanced and built to last.
