Preparing slate coasters for engraving involves several important steps to ensure the best results. First, clean the surfaces thoroughly using a damp cloth or sponge to remove any dust, dirt, or grease. Allow the coasters to dry completely before proceeding to the next step.

Next, assess the slate coasters for any irregularities, such as rough edges or small chips. If necessary, use a fine-grit sandpaper to smooth out these areas, ensuring a flat and even surface for engraving. It’s crucial to handle the coasters gently to avoid causing further damage.

Once the coasters are smooth and dry, consider applying a coat of sealant or primer designed for stone surfaces. This can help enhance the contrast of the engraving and protect the slate from moisture or staining. Make sure to follow the manufacturer’s instructions for drying times and application methods.

Lastly, use a ruler or template to mark the area where you want to engrave. This will help you position your design accurately. With these preparations complete, your slate coasters will be ready for engraving, resulting in a clean and professional finish.
