Masonry Grout Filler is a fine grout (as defined by the American Concrete Institute (ACI) that’s composed of Portland cement, natural sand, selected fine aggregates, and special additives. The product contains admixtures (following ASTM C 476, C207, C260) that allow it to meet the fine grout category (which makes it an ideal grout for masonry blocks, masonry units, and cores, as well as a filler behind marble slabs). Masonry Grout Filler is supplied as a dry powder in pre-weighed bags that are ready to use on-site (this only requires adding clean water to produce a pourable grout).
The surface should be sound, clean free from loose materials, grease, laitance, dust, etc.
For the preparation of masonry grout mixture, pour into a container 6.5 - 8 liters of water for each 50 Kg bag of Masonry Grout Filler.
Slowly add the powder to the water while mixing with an electric drill tted with a suitable paddle for 2 minutes. Then continue mixing at medium-high speed for another 2-3 minutes until achieving a uniform, lump-free pourable consistency mix. The total mixing time is 4-5 minutes approx.
Please do not add water to the mix once it starts to stiffen.
Apply Spatter Dash SB prior to the application of Premix Plaster S.
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 min.
Avoid air entrapment between the gaps while pouring the grout material.
For high lift grouting, the mixed material should be pumped or poured from a height to ensure the desired grout ow spread smoothly within the gaps.
We recommend using a mechanical grout pump for masonry grout placement as it will give more e cient lling and help in grout pumping in high rise structures.
Clean all tools immediately after nishing by water. Clean hardened materials mechanically.
