Masonry Grout Filler is a ne grout category de ned by American Concrete Institute (ACI), and is composed of portland cement, natural sand, selected ne aggregates, and special additives. The Masonry Grout Filler contains admixtures following ASTM C 476, C207, C260 to meet the ne grout category. Masonry Grout Filler is supplied as a dry powder in pre-weighed bags ready to use on-site, which requires only the addition of clean water to produce pourable grout. Masonry Grout Filler is ideal for grouting masonry blocks, masonry units, cores, and a ller behind marble slabs.
The surface should be sound, clean, and free from loose material, grease, laitance, dust, etc.
To prepare a Masonry Grout mixture, pour 6.5 - 8 liters of water (for each 50 kg bag) into a container. Add the powder to the water slowly while mixing with a low-speed electric drill fitted with a suitable paddle for 2 minutes. Then increase the speed to medium - high and mix for 2 - 3 more minutes (until a uniform, pourable, and lump-free consistency is achieved). The total mixing time should be around 4 - 5 minutes. Do not add water to the mixture once it begins to harden.
Pour the mixed material into the gap between masonry blocks, cement panels, or behind marble or gypsum board (within the open time of 30 - 45 minutes). (Make sure there’s no air trapped between the gaps while pouring the grout).
For high-lift grouting, the mixed material should be pumped or poured from a height to ensure the desired grout flow and for the material to spread smoothly within the gaps).
We recommend using a mechanical grout pump for masonry grout placement as it will fill the gap efficiently and help the grout pumping process in high rise structures.
Clean tools and equipment with water immediately after use. Remove hardened material mechanically.
