Koester - PSM three-component mineral mortar

A special, silicate-polymer based, mineral, three-component mortar. It is characterized by very high chemical resistance, especially to harmful salts, oils, fats and acids. It is used to protect vertical and horizontal surfaces of mineral substrates where high acid resistance is required.

Properties

• based on polymer-silicate
• high chemical resistance to the action of acid in
• The fully cured mortar is characterized by a very high compressive strength and high abrasion resistance
• it is not pressure-tight

Application

• sealing horizontal and vertical surfaces on all mineral substrates, such as brickwork, cement plaster, concrete
• can be used in damp and wet rooms, when high demands are placed on chemical resistance to acid
