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. |
|
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. |
|
Packaging :- |
♦ Block Joining Mortar is available in 40 kgs PP laminated bags. |
|
Advantage :- |
♦ High bond strength |
♦ No shrinkage cracks |
♦ High thermal insulation |
♦ Zero wastage |
♦ No curing required |
♦ High coverage |
♦ Economical |
♦ Premixed |
