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.

Matt if you want saturated colour without a sheen, and if the surface is rough or uneven. Semi-gloss where the material is smooth and is meant to shine as well. Both protect against water, oil and staining in the same way.

Is it suitable for a brick floor indoors?

Yes - brick on floors and walls is among the recommended substrates, indoors and out. Terracotta and brick are the materials where the deepening of colour shows most.

What happens if I apply too much?

Any excess that does not soak in dries on the surface as a glossy patch or as runs. So work thinly and in sections, not generously, and lift any excess before it dries.

Wet-look stone sealer, matt - ProtectGuard WL Mat

Deepens the colour of brick, terracotta, natural stone, sandstone and concrete with a matt finish - a wet-stone look without the shine. The acrylic sealer protects against water, oil and staining and forms no film, so the material stays vapour-permeable.

Natural stone

ProtectGuard WL Mat, from the Wet Look range, visibly deepens the colour of the material: brick, terracotta, sandstone and concrete look as they do after rain - except that here the effect stays.

The only thing separating it from its twin, WL Semi-gloss, is the finish. Matt gives a saturated colour without reflections and is the better choice on uneven surfaces: gloss on old brick or split stone picks out every irregularity, while matt softens it visually.

Coverage is 10 m² per litre, applied in two coats 15-30 minutes apart, depending on the porosity and temperature of the material. The surface is dry after a day, and the final appearance settles after 5-7 days - judging the colour earlier can mislead.

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.
