Do I need to seal my slate floor?

While slate is relatively good at resisting water (why it’s often used in roofing), it is still somewhat vulnerable to liquids, especially the acids found in food and drink. We would strongly suggest that a sealant is periodically applied to your slate floor. This will also help protect against scratches, to which slate is much more vulnerable. We’d suggest that you regularly and carefully sweep and vacuum to remove any dirt or grit that accumulates on the floor as this can leave scratches when trodden on. A sealant can create a protective layer, meaning that this barrier gets worn down by such erosion, rather than the stone itself. We can consult with you to find the best sealant for your slate floor.
