Yes. Natural slate tiles must be sealed after installation and resealed every one to two years. Without sealing, the porous surface absorbs water and stains from oil, turmeric, and common household spills, leading to permanent discolouration that is difficult to reverse.
White salt deposits on slate cladding form due to moisture movement through the stone or the substrate behind it, carrying mineral salts to the surface. Clean with water and gentle scrubbing to remove surface residue. If deposits reappear, the underlying moisture source needs to be addressed this is a deeper issue than surface cleaning.
Natural slate with a cleft or textured honed finish provides grip on bathroom floors. Polished or over-honed slate surfaces become slippery when wet and are not suitable for wet floor areas. Specify the finish clearly when ordering and confirm it is rated for wet indoor use.
Yes dust and fine dirt settle into the textured surface of natural slate and cannot be removed by dry sweeping alone. Proper cleaning requires water and scrubbing. In indoor areas this means regular wet mopping, which is a practical consideration buyers should factor in before choosing natural slate for a living space.
Natural cleft is the raw split surface of the stone as it naturally separates along its layers rough, uneven, and highly textured. Honed finish is achieved by grinding the surface to create a smoother matte result. Natural cleft provides better grip outdoors but is harder to clean. Honed is easier to maintain and better suited to bathroom interiors.
Slate tiles handle weather and moisture exposure when properly sealed and installed. In very high-rainfall regions, sealing frequency should be increased and tile condition inspected annually. Delamination the natural stone layers separating is the key structural risk when tiles are left unsealed. Sealing immediately after installation and annually thereafter significantly reduces this risk in all outdoor conditions.
