Application Guidelines:
Surface Preparation:
Before applying BlockMaxX MM22 substrate and background surfaces must be clean and free from dust, organic debris, oily or greasy substances and muds. Also, ensure to put water on the blocks and remove the excess water.
Mixing
Before applying BlockMaxX MM22 substrate and background surfaces must be clean and free from dust, organic debris, oily or greasy substances and muds. Also, ensure to put water on the blocks and remove the excess water.BlockMaxX MM22 is to be mixed with recommended quantity of potable water in non-corrosive container. Proper mixing is essential to achieve specified application and values. For proper mixing electrical agitator can be used. Once mixed, keep it for about 5 minutes and mix it again prior to using.
Application
Apply BlockMaxX MM22 with special toothed trowel and then keep the blocks in line with proper alignment. Care should be taken that excess mortar has to be removed before it dries. Ensure that it does not have any surface film which otherwise has to be removed and re-applied with fresh mix. It should be applied in a thin layer to enable the steadiness of the blocks.
Recommendations:
- BlockMaxX MM22 does not need water curing.
- Ensure to clean all the Tools with water immediately after use. Also, mechanically remove all the hardened materials.Ensure to clean all the Tools with water immediately after use. Also, mechanically remove all the hardened materials.
- The 2 cm separation between the top of the block wall and the bottom of slab or beam should be filled with suitable compressible material
- Make sure that the first layer of blocks is fixed proper with proper alignment
- Do not apply BlockMaxX MM22 during raining, high winds and sand storms
- During summer season, working area should be covered to prevent the direct sun effects.
- Do not apply on surface that has temperature less than +5ºC.
Storage:
- BlockMaxX MM22 is to be covered well and stored away from heat, Sun light and moisture. Also, it should be kept preferably on pallets.
- Shelf Life: 12 Months from date of manufacture if covered and stored well as indicated above.
- Care should be taken that no hard & lumpy materials are used.
Health & Safety:
- It contains Portland cement which becomes strongly alkaline upon mixing with water and this may cause skin irritation when exposed for very long time.
- Avoid contact with eyes and inhalation of dust. In case of skin/eyes contact, wash with plenty of clean water and seek medical attention immediately.
- It is highly recommended to use all relevant Personal Protective Equipment while handling it and work in well ventilated conditions while applying it.
