Potassium Silicate Mortar

Additional Details

Potassium Silicate Mortar is widely used for Acid Resistant Bricks &Tiles lining works as Bedding & Jointing Mortar for Tanks, Floor, Drain, Foundation etc.

Resistant

It is resistant to Oxidizing & Non-oxidizing Acids, & Chlorine Gas except Hydrofluoric Acid.

Resistant to temperature

1000° C (Max.)

Preparation of Mortar

Preparation of Mortar generally consists of Solution & Powder. In order to obtain good working consistency, the average mixing ratio is 1 Pbw of Solution & 2.5-2.75 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.

Surface Preparation

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.

Setting / Curing

Potassium Silicate Mortar is a Self-hardening due to its chemical reaction which occurs when the Powder & Liquid are mixed together.

• An initial setting occurs in 6 to 8 hrs. at 30°C
• Final Setting occurs in 24 to 48 hrs. at 30°C
• Curing time: 7 days at 30°CC

Please ensure that no water shall be spilled over the bricks lining works before it completely cured.

Acid Curing

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.
