Slate is a foliated, layered stone that can flake and hold mineral deposits. We clean slate gently and apply a stabilising sealer to protect its rich, layered colour.

Slate is foliated — it sheds thin layers, especially when unsealed or cleaned with harsh products, leaving a rough, dusty surface.
White, powdery mineral salts (efflorescence) and hard-water scale collect on the layered surface and are hard to remove safely.
Without an enhancing sealer, slate's rich colour fades unevenly and the surface looks tired and inconsistent.
We clean slate gently to remove scale and efflorescence without forcing layer shedding, then stabilise the surface and apply a penetrating or enhancing sealer. An enhancing sealer deepens the colour to a rich, true-to-stone finish while protecting against moisture and future flaking.
Slate needs a penetrating sealer and gentle, pH-neutral cleaning to prevent flaking and efflorescence.
Slate needs a maintained penetrating or enhancing sealer and gentle, pH-neutral cleaning. Avoid acidic products and abrasive scrubbing that force flaking, and reseal every 1–2 years to keep the colour rich and the surface stable.
