Installing natural stone flooring involves carefully placing each piece with a strong adhesive or mortar to secure it in place. A notched trowel helps distribute the adhesive evenly, and spacers ensure consistent grout lines. Once the stone is set, grout is applied, and excess is wiped away with a damp sponge. Sealing the stone after installation helps protect against stains and moisture infiltration. The floor should be left undisturbed for at least 24-48 hours to allow the adhesive and grout to cure fully. Regular maintenance, including gentle cleaning and periodic resealing, will keep natural stone floors looking beautiful for years to come.
