DESCRIPTION:
CEMIX BUILDERS SAND is a graded No.1 sand, used in conjunction with cement and water to form a mortar.
TYPICAL USES:
Used for applications including:
– Brick & Block Work
– Exterior Plastering
– Roughcast
ADVANTAGES:
– Minimal chloride present, minimising possibility of efflorescence
MIXING:
A general recommendation for a mortar mix is a
4:1 ratio of CEMIX BUILDERS SAND with CEMIX GP CEMENT and one measure of CEMIX PLIMORTAR. Water as required.
Note: CEMIX PLIMORTAR is used at a ratio of 1:40 with cement. For more information, refer to the CEMIX PLIMORTAR datasheet.
DRYING & CURING TIME:
It is recommended that all mixes containing CEMIX GP CEMENT be cured for at least 28 days. Avoid walking or driving on fresh concrete for at least 7 days. To attain the maximum compressive strength of mixes, minimise water loss during the curing process. Regardless of the curing method, do not apply any sealers to freshly laid concrete for 28 days.
CLEANING:
Clean tools with water immediately after use. If cementatious material becomes set on tools, remove using CEMIX CONCRETE DISSOLVER.
LIMITATIONS:
The success of any project involving CEMIX BUILDERS SAND is dependent on a variety of factors. Care and attention must be given to batching, mixing, selection of sands / aggregates / admixtures, placing, finishing, curing and formwork.
