AdSeal Stone & Slate Protector

AdSeal Stone & Slate Protector has been uniquely designed to give outstanding results on natural materials such as Stone, Slate, Travetine, Terracotta, and even Clay (in clay paviors)
Geological materials have different physical and chemical structures from man-made products which is why they need special treatment.

A natural, sympathetic look

For a MATT, colour enhancing finish, apply one coat or, if a delicate sheen is required, apply two coats.

Indoors and light to medium trafficked areas; with correct maintenance and depending upon surface type, potentially 10 years plus. Externally colour will remain for 1 – 2 years although protective effect will remain for longer, potentially 4 – 6 years, depending upon surface type.

A major design feature of this product is that it is easily re-coatable and does not need stripping before future treatment as maintenance coats cross link into original forming a monolithic layer. Down time is minimised with rapid cure additives. Fading of the colour and reduction in protective effect take place more rapidly in heavily trafficked areas and these areas can be easily ‘touched up' without the need to strip the original coat. Lower trafficked areas will only need retreating very occasionally, if ever.


Sweep regularly to remove abrasive dirt and grit from the surface and rinse down weekly with a hose (not jet washer) externally or internally mop weekly using a mild detergent if required. Spills and marks should be wiped up as soon as possible and not allowed to dry on. Heavy stains can be removed using AdSeal Orange Degreaser.

Should signs of wear appear a maintenance coat can be applied. Clean and thoroughly dry surface to be treated. Apply single ‘tight' coat in accordance with standard application instructions. The new coat will cross link into earlier coats so there is no need to strip unless resin build up or blemishes are an issue.
