Preparing your slate coasters before engraving is essential for achieving a clean and professional result. First, you should start by cleaning the surface of the coasters thoroughly. Use a damp cloth or sponge to wipe away any dust, dirt, or grease. Allow them to dry completely before proceeding to the next step.

Next, it’s important to inspect each coaster for any imperfections. If you find rough edges or chips, consider lightly sanding them with fine-grit sandpaper. This will not only smooth the surface for better engraving but will also help the engraving tool glide more easily during the process.

After sanding, wipe the coasters again with a damp cloth to remove any dust created from sanding. Once fully dried, apply a thin layer of painter’s tape or masking tape over the area where you plan to engrave. This will protect the surrounding areas and help mark the engraving spot for accuracy.

Lastly, ensure your engraving design is ready and properly sized. Align the design on the tape and secure it in place, so you have a clear guide to follow while engraving. By following these steps, you’ll set up your slate coasters for successful and beautiful engraving.
