Scratched slate hearth, can anyone help?

[Ramatea]

Hi,

Just wondering if someone knows how to remove a scratch from a slate hearth?

We have just had one put in and I have very carelessly scratched it, I would really like to get it perfect again.

Many thanks for any help.

Mix mild detergent with water, dip a cloth on it, and wipe the cloth on the hearth to remove dirt and grease. Rinse with water. Next, apply oxygen bleach solution to disinfect the slate. Rinse with water. Wipe it dry with old cloth. Let it dry completely.

Apply acetone stripper on the entire hearth. Sand lightly with grit sand paper. Brush off powdery residue with paint brush.

Select the areas that need repairing. Use masking tape to create a perimeter around the "for repair" areas.

Using a portable electric polisher, select the proper disc to use (the grit number) for honing. Usually, you start with a lower grit number, particularly 100-grit, and up the level of the disc's grit gradually to achieve a consistent polish, and back to lower grit number for finishing.

If it's just a light scratch then skip that last part. Use the proper disc for polishing light scratches. Sometimes mechanical grit sandpaper can do the job.

Using sandpaper or a wet polisher, buff the entire hearth one last time to even out the color of the slates.

Remove pulverized remains (from honing) using a paint brush, putting extra attention on uneven areas. Wash the stones with a natural stone cleanser to remove traces of acetone stripper and to neutralize the Ph level of the slates. Rinse with distilled water. Don?t use mineral water as the last rinsing solution as this may cause staining. Let it dry overnight. Use a fan to hasten the drying process.

You might want to finish with a sealant, but that's up to you.

I use WD40 to hide small scratches on my polished slate hearth. It works a treat but I wouldn't use it on non polished slate.

Rub a small bit of linseed oil into the scratched slate should do the trick.

The person who installed the hearth might be able to help?

I've been told wet and dry sanding paper works.
