Scentus AAC Block Adhesive 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. AAC Block Adhesive is pre-mixed, easy to apply high quality mortar comprising of cement, graded sand and admixtures. AAC Block Adhesive replaces conventional jointing mortar of 12-18 mm thickness with highly versatile 3-5 mm thickness. Scentus AAC Block Adhesive helps to speed up the build process and achieve the required insulation performance of AAC Blocks for the buildings. AAC Block Adhesive (Thin joint masonry) is a fast, clean, accurate system for construction using autoclaved aerated concrete blocks of close dimensional tolerance.
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
- Eliminates lengthy and cumbersome processes of site mixing, thus transport and storage of all individual materials is avoided
- Easy to 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
- Ready for subsequent application like plastering just after 24 hours of application
- 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.
Surface Preparation
- The base surface should be properly cured prior to application of AAC Block Adhesive.
- 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 AAC Block Adhesive 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 AAC Block Adhesive 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. The AAC Block Adhesive is now ready for application.
Application Procedure
- Layout the wall in which AAC Block Adhesive is to be used and mark openings like door, windows, any architectural appurtenances etc.
- Put a thin layer of AAC Block Adhesive in the thickness of 3 to 5mm 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 AAC Block Adhesive in proper line and level.
- After placing the first block apply the AAC Block Adhesive 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.
