Mix Ratio

• For General Applications, use 4.5 – 5 Litres of clean, potable water per 20 kg of product

 
Mix Process

• 1. Davco Lanko 302 Cement Accelerator must always be pre-diluted before addition to the concrete or sand/cement mortar.
• 2. Always add the correct dose of Davco Lanko 302 Cement Accelerator to the gauging water and never add directly to the dry sand/cement mix.
• 3. Always add powder to the liquid while mixing
• 4. The actual dose rate will be affected by temperature and mix
  design, but the following can be taken as a guide:
  1. Bricklayers Mortar 1L per 40kg bag of cement
  2. Cement Render 1L per 40 kg bag of cement
  3. Concrete Mix 1L per 40 kg bag of cement
  4. Cement Based Tile Adhesive 125L per 20 kg bag of cement based tile adhesive
• 5. For addition to cement based tile adhesives, add 125ml Davco Lanko 302 Cement Accelerator mixed into the amount of clean water (as specified by the manufacturer) with each 20kg bag of adhesive.
• 6. Davco Lanko 302 Cement Accelerator will reduce the amount of working time that the concrete or sand/cement mix normally provides. Always take this into account by mixing smaller batches and carrying out work in smaller stages.
• For any additional mixing instructions not covered above, contact Sika Australia.

 
Performance

• When added to concrete mixes and sand/cement mortars, Davco Lanko 302 Cement Accelerator will achieve 7 day compressive strengths in 48 hours
• When added to cement-based ceramic tile adhesives, Davco 302 Cement Accelerator will enable grouting in 2 hours
