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.
Technical Specifications :-
♦ Appearance : Grey Powder
♦ Water Required : 25 to 30%
♦ Pot Life : 1.5 - 2 hrs at 27 degree centigrade
♦ Tensile Adhesive Strength : 0.34 MPa (as per ASTM-C1660)
♦ Shelf life : 12 months
♦ Coverage : 18 - 20 sq. ft. (for 4" thick blocks). One bag of 40 Kgs should ideally be sufficient for 1 cubic meter of AAC Blocks.
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.
► 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.
♦ 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.
♦ Block Joining Mortar is available in 40 kgs PP laminated bags.
