Depends on the substrate roughness and thickness of layer applied. As a guide, one 25kg bag yields approximately 12.5 litres of mortar.

1.0kg of Parex 100 Newton Grout will yield approximately 0.5 litres of mixed grout at the recommended water addition.
1 tonne of Parex 100 Newton Grout will yield approximately 0.52 m³ of mixed grout at the recommended water addition.
The yield per 25kg of Parex 100 Newton Grout is approximately 12.5 litres.

• Do not exceed stated water addition.
• Not to be used for concrete repair works.
• Do not use vibrating pokers.
• If mixing with a drill and paddle:
  • The drill shall be high torque, slow speed (i.e. 200 to 500 rpm) with a suitable grout stirrer.
  • Use a clean, rigid mixing vessel - flexible containers (e.g. 'gorilla tubs') are unsuitable. 
  • Add the appropriate quantity of clean, potable water to the mixing vessel first and gradually add the powder to the water, mixing continuously. 
  • Keep the mixing head in the material - refrain from lifting in and out, as this will introduce air. 
  • Once all powder has been added, mix until homogeneous (i.e. at least 3 minutes). 
  • Do not try and mix too many bags at a time! Most drills and paddles are only capable of mixing one bag at a time. Large volumes require specialist machinery. 
  • Once fully mixed, leave the grout to de-gas for one to two minutes before use.
• Use only on clean, sound substrates (concrete shall be soaked to saturated surface dry (SSD) condition). 
• Avoid application in direct sun and / or strong wind.
• Pour or pump continuously from one side only (keep header boxes / hoppers topped up for the duration of the application). 
• Keep exposed surfaces to a minimum.
• Do not add additional water during the surface finishing, as this will cause discoloration and / or cracking.
• Protect freshly applied material from freeze-thaw action.
• If applying in cold conditions (i.e. at 0^oC to +5^oC) the application area should be covered (e.g. use of a heated tent system) to create a micro-climate, which should then be heated to ~+20^oC for a minimum of 2 days prior to application. Store the Product, water and equipment in this environment until also at ~+20^oC.
• Following application and if applied in cool conditions, or if cold conditions are expected, the use of insulating blankets or heated curing blankets is recommended for at least 48 hours to protect the fresh grout from cold temperatures and frost. 
• To avoid cracking in warm temperatures, keep bags cool and use cold water.
• When the ambient temperature is warm, protect the working area from direct sunlight with temporary shelters or canopies. Do not expose equipment, materials or application to direct sunlight. 
• When working in warm conditions and if being used, cover hoses with white membranes (or similar) to reflect heat and keep the hoses cool (or, if possible, do not use black / dark coloured hoses). 
• To help control the exothermic reaction, particularly at higher layer thicknesses, it is recommended that the grout is cured under water soon after setting has started (i.e. after approximately one hour). Curing under water is recommended for at least 48 hours.

Pour the required quantity of clean, potable water (4.5 litres per 25 kg bag, or 180 litres per one tonne) into the clean, suitable mixing vessel for each complete unit of Parex 100 Newton Grout to be used. Flexible mixing vessels (e.g. 'gorilla tubs') are unsuitable - rigid vessels shall be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque, slow speed (i.e. 200 to 500 rpm) drill with an appropriate grout stirrer, or a grout mixer set on slow speed for small mixes. The use of a drill and paddle (in most circumstances) is only suitable for mixing one bag at a time. For larger mixes, use forced action type mixers (not concrete tumble mixers which do not apply sufficient shear, nor high speed or colloidal mixers, as these may cause thixotropy, leading to loss of flow). This Product is not suitable for mixing by hand. If using a drill and paddle, keep the mixing head in the material - refrain from lifting in and out, as this will introduce air. It is of utmost importance that the Product is mixed thoroughly enough that a grout consistency is obtained without the addition of further water (i.e. for at least 3 minutes). Fresh grout should be allowed to stand until the air entrapped by mixing has been released before application (typically one to two minutes). 

Grout should be placed within 10 minutes of mixing, or 60 minutes if kept mobile prior to placing. Continuous placing is important, pouring or pumping from one side of the formwork until the grout appears at the opposite side of the grouting area. Keep header boxes / hoppers topped up for the duration of the application. Do not disturb once grouting has been completed.

Parex 100 Newton Grout may be placed at temperatures between +5°C and +35°C. For placing at temperatures outside this range, contact Sika® Technical Services Department for advice.

After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’.

Placed grout, which is exposed, should be cured in accordance with good concrete practice.

Protect the fresh material from premature drying using an approved curing method (e.g. curing compound such as Sikafloor® ProSeal, moist geotextile membrane, hessian, polythene sheet, under water, etc.).

In cold weather, apply insulating blankets or heated curing blankets to protect the Product.

To help control the exothermic reaction, particularly at higher layer thicknesses, it is recommended that the grout is cured under water soon after setting has started (i.e. after approximately one hour). Curing under water is recommended for at least 48 hours.

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
