Water-repellent sealer for absorbent paving and concrete

Water sinks into the surface, stains stay, and the colour dries unevenly after rain. A water-repellent sealer reduces that uptake without closing the pores, so paving, concrete and stone absorb less and are easier to keep clean.

How to protect absorbent paving

An absorbent surface takes in water along with whatever the water carries. That is why it darkens unevenly after rain and why stains go deeper and are harder to shift.

A water-repellent sealer reduces that absorption without closing the pores. Water and dirt no longer get into paving, concrete or stone as easily, and routine cleaning takes less time. You choose a clear finish that keeps the natural look or a wet-look finish that deepens the colour.

Apply it to a clean, dry, fully cured surface. If there is efflorescence or staining, remove it first, because a sealer locks in whatever it finds. Sealing is periodic maintenance that you repeat from time to time.

Frequently asked questions

Does a paving sealer close the pores?

No. A water-repellent sealer reduces water uptake without closing the pores. The clear version keeps the paving's natural look, and the wet-look finish deepens its colour.

Will a sealer remove stains from paving?

No. A sealer does not remove existing dirt, it locks it in. Wash off stains, efflorescence and green growth with the right cleaner first, and seal a clean, dry surface.

How often should paving be resealed?

Sealing is periodic, and how often depends on the product, the surface and the traffic it carries. Check the renewal guidance in the sealer's technical data before you buy.

Is it worth sealing paving under a carport or in a garage?

Yes, if a car stands there. Rain matters less under a roof, but oil, grease and tyre marks remain, and a sealer limits how far they soak in.
