Masonry Grout Filler

Cementitious masonry grout (Premixed).

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).

Uses

  • On cement-based masonry blocks / units, behind marble and cement panels, and on tiles or slabs, etc. 
  • Application behind gypsum boards.

Advantages

  • Factory controlled pre-blend ensures consistently high quality. 
  • Requires only the addition of water on-site at the time of use. 
  • Suitable for the MENA region’s harsh weather conditions. 
  • Easy application with a uniform workflow (this enables high productivity and superior finishing). 
  • Strong adhesion. 
  • Good mechanical resistance. 
  • Excellent workability.

Usage Instructions

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.

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 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.
