A plant-based product for removing mortar residues, cement laitance, lime deposits and salt efflorescence. Intended for cleaning up after building work; the manufacturer states that no neutralisation is needed after rinsing.
Surface
Block paving
The surface the manufacturer intends this preparation for.
Block pavingA product for one specific problem: what building work leaves behind. Cement laitance on freshly laid paving, mortar marks on brick, lime deposits, salt efflorescence.
What sets it apart is the base - the manufacturer states plant-derived ingredients (wheat, maize, beet, tree resin) and no need to neutralise after rinsing. That is a real difference from acidic products, where the substrate has to be neutralised before a sealer can go on.
The dwell time is short: five minutes at most, then rinse with plenty of water. The product must not dry on the surface - that is the commonest cause of streaking. Coverage 6 m² per litre.
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 We do not quote a number of years, because it depends on traffic, sun and whether the drive is salted in winter.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.
Yes - that is its typical use. Cement laitance left under a sealer comes away with it. After washing and rinsing, let the paving dry all the way through.
The manufacturer states no toxic substances and no need for neutralisation, but any cleaner at working strength is worth keeping away from planting - covering plants before work is standard whatever the base.
The manufacturer allows brushing with a stiff brush once the deposit has softened, then rinsing again. Do not extend the dwell time beyond five minutes or let the product dry.
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.
The manufacturer states 1 l to approx. 6 m²; consumption rises with the thickness of the deposit.
