Natural stone sealer, wet look EI-10 EKSIL

A water-based film-forming sealer for mineral surfaces that brings out the colour of stone, brick and concrete. The manufacturer classifies it as a mixture that is not hazardous. A second coat strengthens the effect.

Block paving

The surface the manufacturer intends this preparation for.

Block paving

EI-10 is the water-based route to a wet-stone look: a film-forming product based on a copolymer dispersion that brings out the colour of stone, brick and concrete.

You choose it where the wet-look effect has to be achieved without solvents - working indoors, for instance, or among planting. The manufacturer classifies it as a mixture that does not meet the criteria for a hazardous one, with no pictograms required.

A second coat is applied to strengthen the effect, not for protection. The product is available from 0.1 l, so a sample can be bought to check the shade before a larger order.

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.

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

New paving has to season first. Manufacturers state that period on the data sheet - usually around 28 days from the date the block was made. The figure for each product is under "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.

Will the sealer change the colour of my paving?

That depends on the finish given in the technical data. An invisible product leaves the colour alone, a wet-look version deepens it permanently, and a colour sealer gives it a new shade. Each product's finish is listed under "Technical data".

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. We do not quote a number of years, because it depends on traffic, sun and whether the drive is salted in winter.

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 - products that allow slight surface dampness - say so in their technical data.

How much do I need to buy?

Use the calculator under the product description: it takes the manufacturer's coverage figure, the number of coats and the absorbency of the substrate, and turns them into pack sizes. On older, thirstier paving, work to the lower end of the coverage range.

Will sealing make the paving slippery?

Penetrating products form no film on the surface and do not change its grip. Where a manufacturer says something about slipperiness, we quote it in the technical data. If the surface is already slippery, the right product is an anti-slip treatment, not a sealer.

Can I buy a sample to test the colour?

The manufacturer lists a 0.1 l pack in the GPSR record. The sizes available in our shop are shown when you choose a variant.

Is it suitable for brick and roof tiles?

The manufacturer lists concrete, brick and roof tiles among the uses. On a roof, as always, what decides is the state of the covering and how clean it is before application.

The technical sheet and safety data sheet will be available after approval.

Coverage calculator

This product has no stated coverage yet, so we cannot work out the requirement.

The calculator starts once the manufacturer states the coverage.

Prepare the surface first

An impregnation will not bond to a surface with anything left on it. This is the most common cause of complaints.
