Block Jointing Mortar is a thin bed, high strength, pre-mixed, quality assured mortar comprising of Ordinary Portland Cement, specially graded sand and Polymers. It is specially formulated and easily applied, giving a better bonding with higher air entraining properties.

Features& Benefitsof “Mixfix Jointing Mortar”

• Its fast setting property essentially “glues” the blocks together and the next course is ready to lay within a very sort time.
• Higher bonding strength increases durability and eliminates future maintenance.
• It gives high coverage, due to lower density and higher volumes.
• It is ready for plastering after 24hrs. of laying blocks.
• Being premixed it saves considerable time, labours and increases dimentional stability of the blocks.
• No need for curing post application.
• It increases overall masonry strength and helps in reducing load on the structure.

Areas Of Use :
Laying Bricks And Blocks:

• To join AAC(autoclave arated blocks), fly ash bricks, cement block, hollow block, panel etc.
• Jointing of prestressed concrete slabs, panels.
• Jointing of prestressed concrete slabs, prefabricated panels etc.
• Jointing of cement window and door frames.
• barbecues and fire places.
• Garden and boundary walls.
• screed and compost bins, sand pits.
• Bench stands, bicycle stands.
• terrecing.
• Ornamental pools.
• Repairing of masonary walls.

Surface Preparation :

• When laying new bricks or block walls first construct a sound footing below the first line..
• All substrates should be cleaned and free from dust, oil , grease, curing agent, paint which may affect adhesion.
• Wet the substrates before the application, without leaving water.

Preparation Of “Mixfix Jointing Mortar” :

• Take a small amount of water in a bucket and gradually add “mixfix jointing mortar” in it. mix the product with water in the ratio of approximately 1:4.
• mixing can be done manually or by stirrer.
• Mixing to be done till homogenous mix is obtained.
• After proper mixing, leave the paste for 5-10 minutes for polymeric depersion before application.
• The paste should be kept away from direct sunlight, heat and used within 45 minutes of preparation (after mixing with water).

Application Of “Mixfix Jointing Mortar”:

• Layout the wall you are going to work on and mark openings like door, windows, and any architectural appurtenances, you are including in your design.
• Put a thin layer of Jointing Mortar in the thickness of 3 to 4 mm on the clean and leveled surface using proper trowel on which the block work is to be carried out. Place the block on the laid jointing mortar in proper line and level.
• After placing the first block apply the jointing mortar of the same thickness i.e 3-4 mm for both horizontal and vertical joint of the block.
• Space “mortar boards” about every six feet along the wall, or on each side if the project is small.
• Brush the face of the brick with a foxtail brush to wipe away excess mortar and finish smoothing the joint.
• Continue laying the brick with 3-4mm thickness of jointing mortar until you are levelled with the leads you laid up.

Filling The Joint :

• Spread the mortar across the whole surface using the rubber blade of the trowel and work thoroughly into the joints.

Brushing Off :

• After approximately 10-15 minutes, the mortar should have achieved a semi-dry consistency. Don’t brush this residual mortar into any unfilled joints.
