The effect of atmospheric agents and dirt deposits on porous surfaces such as stoneware and stone or porphyry paving can cause discolouration as well as the formation of a slippery patina. For the special cleaning of very dirty paving, Allegrini proposes SP CLEAN, an acidic descaling detergent specifically for the removal of limescale deposits on hard surfaces. Used with SP MAIN it guarantees the restoration of surfaces which have been subject to atmospheric agents and all kinds of dirt deposits over long periods of time, returning them to their original condition. A product specifically for the deep-down cleaning of ceramic, porcelain, granite etc. The product is applied with a low pressure spray and brushed over the surface to remove deposits of limescale, dirt and various types of contamination from external and internal surfaces subject to foot traffic. SP CLEAN preserves the anti-slip properties of the surface without altering either the structure or the aspect of the tiles, and without damaging the underlayer or the fixing agent.
For best results, the product must be applied undiluted onto a dry surface. Wet the area to be treated and brush for a few minutes with the machine fitted with a black/green disc and leave the solution on for another 10 minutes. Remove the excess product with a wet vacuum and rinse the surface with cold water, preferably with a high-pressure jet. Repeat if necessary.
In case of the presence of both dirt and large quantities of limescale, mix SP CLEAN with SP MAIN in a ratio of 50/50 up to 20/80 and apply to the dry surface.
The use of SP MAIN is not recommended for surfaces with low resistance to acidity such as marble, concrete, wood and metal.
