A water-based decorative sealer that gives the surface a glittering finish without changing the colour of the substrate. Penetrating the material, it limits the uptake of water and soiling and the formation of carbonate efflorescence.
Surface
Block paving
The surface the manufacturer intends this preparation for.
EI-12 is a decorative product: it gives the surface a glittering finish. In the clear version it does so without changing the colour of the substrate - the concrete or paving keeps its own shade and only gains the light effect.
Besides decoration the product works as a sealer: penetrating the material, it limits the uptake of water and soiling and the formation of carbonate efflorescence. Coverage 4-6 m² per litre, drying 60-120 minutes.
The manufacturer provides for two coats, with a third to increase gloss. The excess has to be removed before it dries - runs show clearly on a glitter finish.
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 We do not quote a number of years, because it depends on traffic, sun and whether the drive is salted in winter.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.
The effect is one of light and depends on the angle it falls at - it shows most in sunshine and under directional lighting. The manufacturer requires a test patch before the full job precisely because the effect is hard to predict from a description.
The clear version leaves the substrate colour unchanged and adds only the glitter. The pearl versions (graphite, anthracite, grey) change the shade of the surface. This product is the clear glitter version.
The manufacturer lists wood among the absorbent and porous materials covered. As always with timber, the test decides - species and finish vary more than mineral substrates do.
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.
A third coat increases gloss and coverage. Consumption depends on how absorbent the substrate is.

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