A solvent-based sealer that deepens the colour of paving and concrete for a wet-look finish. The manufacturer specifies two thin coats at least 24 hours apart.
Surface
Block paving
The surface the manufacturer intends this preparation for.
EI-15 is the classic wet look for paving: a solvent-based product that deepens the colour of concrete distinctly rather than subtly.
The price of that effect is discipline in application. The manufacturer specifies two thin coats at least 24 hours apart, at an ambient and substrate temperature of 5-25 °C. One thick coat does not substitute for two thin ones - the excess stays on the surface.
Coverage 8-10 m² per litre for one coat, full durability about a day after the last coat. Also available in 20- and 30-litre containers, which matters on large areas.
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.
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.
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".
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 We do not quote a number of years, because it depends on traffic, sun and whether the drive is salted in winter.
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.
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.
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.
Because the first has to release its solvent and bond with the concrete. A second coat applied too early dissolves the first instead of resting on it, and the result comes out patchy.
The manufacturer gives 5-25 °C for both the air and the substrate. On paving warmed by the sun the solvent evaporates before the product can penetrate.
No. Deepening of colour is always relative to the substrate - on dark paving the effect is more pronounced. That is why the manufacturer requires a test before the full job.
The technical sheet and safety data sheet will be available after approval.
Enter the area and how absorbent the substrate is. We work out the litres and the packs.
Consumption depends on how absorbent the material is and on how it is applied.

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