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 |
