Visibly deepens the colour of concrete patio slabs and strongly lowers their water uptake. Once dry it gives a wet look, without making the patio more slippery or closing the pores of the concrete. A ready-to-use, water-based siloxane and silane sealer.
Concrete and floorsHBP-2 is an excellent sealer for concrete patio slabs with a wet-look finish. A multi-component siloxane and silane product that strongly lowers water uptake and permanently deepens the colour of the concrete.
On a patio the difference shows most after rain: a slab sealed with HBP-1 returns to its pale shade, a slab with HBP-2 stays darker for good.
The product does not increase slipperiness. Like the colourless version it is water-based, alkali and UV resistant, and does not close the pores.
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 - 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.
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.
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.
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.
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.
Composition and finish. The -1 versions are single-component, based on siloxanes alone, and dry colourless. The -2 versions are multi-component - siloxanes with modified silanes - and give a lasting wet-look finish. Both meet PN-EN 1504-2 tab. 3 and both leave the pores open.
It depends on how absorbent the slab is, because the product is applied to saturation - so the simplest way to work it out is to seal one square metre, measure what it took, and multiply by your area with a small margin.
After 5-6 hours. Until then, protect the freshly sealed surface from rain and from direct sun.
Apply to full saturation in one generous coat; on absorbent material, repeat the application wet-on-wet.

A sealer will not bond to a dirty surface. Start by cleaning it thoroughly.
