Installation
Mixing Procedure
Mix with clean water in a plastic container. Slowly add the dry powder to water while stirring by hand or power mixer to ensure a smooth lump-free mix.
Recommended Mixes
Dry Powder : Water Ratio
By volume Std HS HD
Pourable / floors 2½ : 1 3 - 3½ : 1 4 - 4½ : 1
Stiff / walls 3 :1 4 : 1 5 - 5½ : 1
By weight Std HS HD
Pourable / floors 1.3 : 1 3 : 1 7 : 1
Stiff / walls 1.9 :1 3.5 : 1 0 : 1
Wall Openings
For small holes and gaps, trowel a stiff mix into the opening to the correct depth. For larger holes, use an appropriate damming material to support the mix until it sets, or, if a fair faced finish is required to both sides, consider using a sandwich construction. Alternatively, the mortar may be precast into convenient sized blocks, a stiff mix being used as a bedding mortar.
Floor Openings
When sealing holes in floor slabs, appropriate shuttering must be installed, cut to fit tightly around any services within the opening, to support the wet mix until it sets. Non-combustible shuttering materials, such as mineral fibre slab, can be left in place, but combustible materials must be removed, after the mix has set. For complex penetrations it may be preferable, to initially form a thin seal around all services, with a nominal 5mm layer of the mortar mix. Once this has set, the remaining depth of seal, should be poured in one operation.
Storage and Disposal
Fire rated mortars should be stored between 5ºC and 30ºC. It should be protected from freezing. Shelf life is 5 years. Waste product is considered to be non-hazardous.
