Write a Review

Description

Block Jointing Mortar is a versatile thin jointing material for laying AAC Blocks, fly ash bricks, concrete blocks etc. The product is specially designed to provide higher bonding as a result of higher tensile adhesion strength.
SilicoFix Block Jointing Mortar is pre-mixed, easy to apply high quality mortar comprising of cement, graded sand and admixtures. This mortar replaces conventional jointing sand-cement mortar of 18-25 mm thickness with highly versatile 3 mm thickness layer and gives instant bonding properties in a day. No need of water curing too unlike normal sand-cement mortar that requires water curing of minimum 7 days to get the required strength.

Features and Benefits
» Thin jointing material with very high adhesion strength
» Pre-mixed and ready-to-use. Only water is to be mixed at site
» Economical. Eliminates lengthy and cumbersome processes of site mixing, thus transport and storage of all individual materials is avoided
» Ease of mix and much faster application
» Thin layer application results in structure being compact
» No water curing is required after application
» Minimizes the undulation of the surface
» Being a thin layer, chances of water percolation is negligible
» Being premixed, it saves considerable time and labour
» Eco-friendly product
» Raw materials are processed, reducing the chances of efflorescence

Areas of Application

» Laying and jointing of fly ash bricks, cement blocks, hollow blocks, AAC blocks etc.
» Jointing of pre-stressed concrete slabs, panels.
» Parapet walls
» Jointing of cement window and door frames.
» Garden and boundary walls.

Usage Instructions

Surface Preparation:-
» The base surface should be properly cured prior to application of Block Joining Mortar.
» The surface must be cleaned thoroughly, with no loose particles or dust.
» The surface must be structurally sound, clean and free from dirt, oil, grease, efflorescence and any other contaminant which could impair the natural bond.
» Surface defects such as cracks, holes or voids should be repaired prior to application.
Mixing:-
» It is very important that Block Joining Mortar is mixed with water properly and thoroughly before use. It is advisable to use a mechanical stirrer for uniform and thorough mixing to save time, labour and for maximum workability.
» Take a clean vessel/bucket, add water to it and put required quantity of Block Joining Mortar in it.
» Mixing Ratio - Clean potable water (approximately 25%-30%) of the weight of the powder is required to be mixed depending upon the thickness of the product to be applied. Water is to be incrementally added in stages to get a smooth, uniform and workable mix. Allow ample of time for initial mixing.
» Ensure that no powder is left unmixed at the bottom of the vessel. Block Joining Mortar is now ready for application.

Application Procedure:
» Layout the wall in which Blocks is to be used and mark openings like door, windows, any architectural appurtenances etc.
» Put a thin layer of Block Joining Mortar in the thickness of 3 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 Block Joining Mortar in proper line and level.
» After placing the first block apply the Block Joining Mortar of same thickness on both the sides of the block continuously keeping a check on the line and level.
» Clean the excess material, if any immediately. Continue the procedure for the entire block work.
Coverage:-
» Under normal conditions the coverage of Block Joining Mortar is approx. 180-200 sq. ft with average thickness of 3mm for a bag of 40 kgs. The coverage area however will depend upon the quality of the substrate and thickness of the material used.
» For best results, proper tools for mixing and application is advised which will result in higher coverage, savings in time and manpower.

Precautions during usage:
» Though it contains non-toxic materials but still care should be taken to avoid dust inhalation while mixing and handling. In case of contact with eyes or mouth, wash with plenty of clean water.
» Keep it in a safe dry place which is out of reach of children.
» Persons who are allergic to cement should take proper precautions before use.
