Will the sealer change the colour of my paving?

Only if you want it to. An invisible product leaves the colour alone, a wet-look sealer deepens it permanently, and a colour sealer gives it a new shade.

How do I know when to seal again?

By how the water behaves. While it still beads on the surface, the treatment is working. Once water starts soaking in and dark patches return after rain, the protection has worn out.

Can I apply sealer to wet paving?

No. Water occupies the pores the product is meant to enter, and stays trapped under the film. The result is often a milky bloom that cannot be removed without stripping the coat. The exceptions are the few products that tolerate slight surface dampness.

Will sealing make the paving slippery?

Not if you choose a penetrating product - it forms no film on the surface and does not change its grip. If the surface is already slippery, choose an anti-slip treatment rather than a sealer.

Can I apply semi-gloss over a surface already treated with the matt version?

Not without advice first. A penetrating product needs open pores, and after the matt version they are already filled, so the new coat may not bond. Before changing the finish on a sealed surface, write to us and we will tell you how to proceed.

Will the gloss dull over time?

The product is UV and frost resistant, so it copes very well outdoors. How fast the sheen fades depends on the traffic the surface takes and how it is cleaned.

Wet-look stone sealer, semi-gloss - ProtectGuard WL

Gives brick, terracotta, stone and concrete a semi-gloss wet-stone look. It protects the surface against water, oil and staining without forming a film - the material stays vapour-permeable. Apply the next coat after 15-30 min.

Block paving

The semi-gloss version of the Wet Look range. It deepens the colour exactly as WL Mat does, but leaves a gentle sheen on the surface - the material looks slightly damp.

This is the ideal choice for smooth, even surfaces: terracotta, porcelain, power-floated concrete, facing brick in good condition. On rough or damaged material the gloss picks out the irregularities instead of hiding them - there the matt version does better.

Application is identical to the matt version: two coats, 15-30 minutes apart, 10 m² per litre, final appearance after 5-7 days.

The usual reason a sealing job fails is not the product but the substrate. A sealer will not bond to a surface with grease, lime efflorescence or an old coating on it.

Wash the paving. Lift oil stains with a degreasing cleaner - water alone, even under pressure, will not shift them.
Remove lime efflorescence with a product made for it, not with hydrochloric acid from the builders' merchant.
Make good the joints and let them set. Sealer applied over an empty joint runs straight into the sub-base.
Wait until the paving is dry all the way through, not just on top. Moisture trapped under the film can bloom it white.
Check the forecast. Rain within a day of application will wash off a fresh coat.

New paving has to season first - usually around 28 days from the date the block was made. You will find the exact time for each product in its technical data.

Before sealing the whole area, test on a patch hidden by a planter or in a corner of the patio. The same product can read differently on two batches of the same material, and on a surface with old coating left on it, it will not bond at all.
