product Description

This is Silicate type, two-part chemical setting mortar. It is recommended against permanently acidic condition, and can withstand much higher temperature compared to other resin type & sulfur type mortar.

Area of Application

K-silicate is principally used with acid resisting bricks and tiles for acid resisting masonry construction, because of its very low cost. It is highly recommended to protect chimneys, incinerators and other high temperature equipment.

Method of Application mixing

K-silicate is prepared by mixing solution & powder to form workable mortar. The recommended ratio of mixing is 1 part solution to 3 parts powder by wt. This ratio will vary depending upon ambient temperature and working conditions. Use clean dry mixing pan. Place appropriate quantity of solution in mixing Pan, and add powder slowly and start mixing thoroughly, until you get smooth paste like mortar. Do not mix more material, then, can be used within 30 minutes.


Mortar is buttered on acid resistance brick/tile as usual bricklayers Method. Brick/tile also should be clean, dry and at ambient temperature. After hardening of the joints, it should be treated with 10 % Hydrochloric acid before the acid resisting lining is place in use. During & after completion of lining, area must be kept dry and free from any other materials and traffic, which can affect setting & curing of K- silicate.

chemical Resistance Properties

K-silicate when completely set hard, resistant to high concentration of oxidizing acids, inorganic acids and salts and most organic solvents at high temperature. It is not recommended against Hydrofluoric acid, fluorides, fluoride salts, water, diluted solutions, alkalis etc.
