Angle grinders and rotary tools are effective for cutting tile already installed on a wall. Here's how to do it:
1. Preparation is Key:
- Mark the Cut Line: Use a marker or pencil to clearly indicate where you need to cut. Accuracy is important.
- Protect the Surroundings: Cover adjacent surfaces (walls, countertops, etc.) with plastic sheeting and painter's tape to prevent dust and debris from causing damage.
- Safety First: Wear safety glasses, a dust mask, and hearing protection. Cutting tile generates dust and noise.
2. Tools and Materials:
- Angle Grinder or Rotary Tool: Choose a tool with a diamond-cutting blade specifically designed for tile.
- Masking Tape: Apply masking tape along the marked cut line. This helps prevent chipping and provides a clearer line to follow.
- Wet Sponge: Have a wet sponge handy to cool the blade and reduce dust.
- Pencil/Marker: For marking the cut line.
- Safety Glasses, Dust Mask, and Hearing Protection: Essential safety gear.
3. The Cutting Process:
- Score the Tile (Optional but Recommended): Before making the full cut, lightly score the tile along the marked line with the angle grinder or rotary tool. This helps prevent chipping.
- Cut Gradually: Don't force the blade. Let the tool do the work. Cut slowly and steadily along the marked line, keeping the blade cool with the wet sponge.
- Use a Dust Collector (Optional): Attach a dust collector to your tool, if available, to minimize dust.
- Multiple Passes: It may be necessary to make several shallow passes to cut completely through the tile, especially with thicker tiles.
4. Post-Cutting:
- Smooth the Edges: Use a tile file or sanding block to smooth any sharp edges.
- Clean Up: Remove the masking tape and clean the area thoroughly.
Tips for Success:
- Practice: If you're new to cutting tile, practice on a scrap piece first to get a feel for the tool and technique.
- Control the Dust: Keep a wet sponge handy to control the dust and prevent it from spreading. A wet saw can also be used if the tile can be removed and placed on the wet saw for cutting.
- Avoid Overheating: Don't overheat the blade. Let the blade cool down periodically.
