A drum mixer will provide adequate mixing. Water must be clean and free from organic matter, tap water is ideal. Use 4-5 litres of water for each 25kg bag of dry material, depending on the consistency of the mix. Record water addition and maintain throughout the mixing period. Conduct trials on site to establish workability and colour. Measure dosage of water per 25kg bag. Contact us for more information.
