Care, Upkeep and Maintenance
After installation, thorough cleaning must be carried out to remove excess grout, cement, stains, dust, soil and other kinds of dirt.
All excess grout, cement or paste must removed and cleaned from joints.
For cleaning, only clean water and neutral detergents and other kinds of cleaning materials.
Cleaning must be carried out immediately after installation, before grout, cement and other kinds of setting materials are dry.
Acids, whether pure or diluted, should never be used.
Only grout, cement, sealants, impregnators and cleaning materials from reliable manufacturers should be used.
The selected sealant, whether water-based or solvent-based, must be able to enhance the color and texture of the stone and make it impervious to oil, grease, fat, dirty water, and stains.
Floor wax or polishing wax should never be used on slate since it alters the color of the stone and makes it more prone to the accumulation of dust and dirt.
