Sodium Silicate Mortar is widely used for Acid Resistant Bricks &Tiles lining works as Bedding & Jointing Mortar for Tanks, Floor, Drain, Foundation etc.
Sodium Silicate mortar are useful in PH range of 0-6 except where sulphuric acid exporser existing in the vaper phase wet-dry exposures or in concentration above 93% It is also resistant to Oxidizing & Non-oxidizing Acids, & except Hydrofluoric Acid & Water.
1000° C (Max.)
Preparation of Mortar generally consists of Solution & Powder. In order to obtain good working consistency, the average mixing ratio is 1 Pbw of Solution & 3 pbw of Powder. This ratio will slightly vary depending upon the temperature and working conditions.
Prepare small batches of Mortar. Stirrer the Solution thoroughly before use. Place the Solution in a suitable mixing pan and add powder in it. Mix thoroughly with a spatula or Trowel. The mixing operation shall be continued until a uniform mixture is obtained.
Make sure that all the Mortar is used from the mixing pan before another batch is prepared.
The cement plastered surface shall be slightly rough in line & level, dry & clean, free from dust, dirt, grease, oil etc., maintaining required slope etc. as no slope can be adjusted or altered in Acid proof lining works.
Sodium Silicate Mortar is a Self-hardening due to its chemical reaction which occurs when the Powder & Liquid are mixed together.
Please ensure that no water shall be spilled over the bricks lining works before it completely cured.
When the bedding & jointing mortar is different, after the bedding mortar is properly set, cure the joints for a minimum period of 72 hours with 20 to 25% HCL acid before applying the resin type mortar. After acid curing, wash the free acid in the joints with clean water & allow sufficient time for thorough drying. Resin mortar shall then be filled into the joints.
All two components are stored in cool and dry place under the roof until ready to use it original unopened (Sealed) containers.
