AAC/CLC BLOCK FIX

ULTRA BOND AAC BLOCK FIX BOND is a factory prepared blend of carefully selected raw materials, Portland cement and graded aggregates and polymers. Designed for use with water to produce high strength thixotropic mortar, for laying aerated light weight concrete, fly ash bricks, cement hollow blocks, cellular concrete blocks or smoothing over the block work surface in layers of up to 12mm thickness, that meet and exceed the requirements of  National and International Standards.

  • Aerated light weight blocks
  • Cellular concrete blocks
  • Fly ask bricks

Application:

For interior and exterior use for preparing thin bed adhesive for AAC, ALC and cellular concrete blocks.

               1) Thin bed mortar for laying blocks: Before placing mortar, ensure the block work to be dry and surfaces cleaned properly. Place the mixed mortar on the block work in thin layers of 2 to 3 mm (or as required by engineers at site) using trowel and place the next layer of blocks on the mortar. Keep joints between the blocks as required by the site engineers and fill the joints with the mixed mortar, using a trowel. Check the plumb of the wall while laying the blocks to keep the walls perfectly vertical to the plumb.

 

 2) Smoothing over the block work: Before placing mixed mortar, apply a bonding layer of 1 to 2mm thick ULTRA BOND DIAMOND AAC Block FIX mortar using a trowel pressing down on the block work. Then apply AAC Block Adhesive at a thickness of 8 to 10mm and smoothen using a sponge or rubber / wooden float.

Coverage

Coverage is based on smoothness and evenness of the substrate, size of blocks used and the thickness of mortar used. A general guide line for coverage of mortar is given when used with 30% Water is added to powder. The following is the coverage table for wall area in Square feet that can be constructed using AAC Blocks of size 600mm X 200mm X 100mm

NOTE: Coverage depends on the substrate evenness and the thickness at which the AAC Block adhesive is applied.

Mixing :

Use approx. 50 kg of  ULTRABOND DIAMOND AAC Block MIX thin bed mortar with Approx. 15 ltrs of potable water. Take water in the container and slowly add the powder into the water while mixing by hand or slow speed mixing machine. Mix for 3 to 5 minutes till a smooth thixotropic mix without lumps is obtained.

Shelf Life:

Factory sealed bags of this product are guaranteed to be of first quality 15 months* if stored off the ground in a dry area, at 21°C and 50% RH. *High humidity will reduce the shelf life of bagged product

Suitable Substrates

•Concrete Blocks.
• Cement Mortar Blocks/Bricks.
• Concrete hollow blocks.
• Aerated Light weight blocks.

Application

For interior and exterior use for preparing thin bed adhesive for AAC, ALC and cellular concrete blocks.

•Thin bed mortar for laying blocks:
Before placing mortar, ensure the block work to be dry and surfaces cleaned properly. Place the mixed mortar on the block work in thin layers of 2  to 3mm
(or as required by engineers at site) using trowel and place the next layer of blocks on the mortar. Keep joints between the blocks as required by the site
engineers and fill the joints with the mixed mortar, using a trowel.        

•Smoothing over the block work:
Before placing mixed mortar, apply a bonding layer of 1 to 2mm thick ULTRA BOND DIAMOND AAC Block FIX mortar using a trowel pressing down on the block work. Then apply AAC Block Adhesive at a thickness of 8 to 10mm and smoothen using a sponge or rubber/ wooden float.
