20kg, 25kg & 40kg

Substrate Preparation:

Typically compacted hardfill prior to pour. Before pouring, ensure the surfaced is dampened with water.

Application:

Empty contents into a wheelbarrow or mechanical mixer or onto a smooth non-porous surface. Add water gradually, mixing thoroughly until a workable mix is achieved. Under ideal conditions a bag of 25kg would require about 2.5 litres of water and a 40kg bag would require 4.0 litres of water. Use mixed concrete immediately, do not allow to stand.

Damp the sub grade before concrete is placed. Upon placing the concrete at site, work sufficiently to remove air voids if any and compact well with a tamping rod working into all areas. Level off the corners and finish flat with a wooden float for coarse finish or a steel trowel for a smooth finish. Use Cemix® Concrete Cure WB to cure concrete, or just keep the surface damp for the first seven days.

Cemix® Multicrete mix consists of a uniformly blended, properly proportioned mixture of stone, gravel, sand, Portland cement and other admixtures approved for use in concrete to improve workability and performance of the product.
