Acid protection


In acid-proof installations special coatings are used if the load with chemicals, high temperatures or abrasion is too high for the building structure. Therefore we developed a suitable acid protection system over several years. This system provides the highest possible protection for your application.

The use of pure silicates, from which glass and quartz sand are also composed of, allows a permanent protection for your building against high loads like concentrated acids or temperatures above 1350° C.


Our system for building protection against high loads consists of various products.

Deeper ruptures and major outbreaks have to be filled with a repair or pouring mortar (e.g. Maleki-RM 500, Maleki-VM 530). Larger unevenness can be levelled out with Maleki-BV 310.

Thereafter a continuous waterproofing is performed. For the single waterproofing use the silicate waterproofing Maleki-SWP 270. For higher application thicknesses or reprofiling works use our silicate putty mortar and grout Maleki-SBS 860.

As an acid- and abrasion-resistant wear layer we recommend the use of the silicate acid protection mortar Maleki-TPC 200. This mortar is extremely resistant in the pH-range 0 – 14 and serves as an ideal final coating.

This system description shows a possible layer structure. The necessity of all single steps or products is dependent on the local conditions. All these steps have to be confirmed in case of doubt. For every application the relevant information in the technical data sheets has to be followed.
