Compulsory Mixer

Pour the correct amount of water into a suitable clean mixing container. While stirring slowly add the complete bag of powder into the water. Mix continuously for 3 to 5 minutes to achieve a uniform and lump free smooth consistency. Do not add more water than the maximum specified.

Concrete mixer

SikaGrout®-3170 R must be mixed using suitable grout mixing equipment combined with agitator for continuous large volume mixing. Volume capacity of equipment should be applicable to the volume of material being mixed for a continuous operation. Equipment trials should be considered to ensure product can be mixed satisfactory. Pour the minimum water ratio in the correct proportion into the grout mixer. While stirring the water, slowly add the powder to the water. Add more water within the mixing time up to the maximum allowed until the desired consistency is achieved. Mix continuously for 3 to 5 minutes. Do not add more water than the maximum specified.

Pre-wetting

The prepared concrete substrate must be thoroughly saturated with clean water for a recommended 4–8 hours before application of the grout. The surface must not be allowed to dry within this time. Prior to application of the grout, all water must be removed from within formwork, cavities or pockets and the final surface must achieve a dark matt appearance (saturated surface dry) without glistening.

Placing

Apply the material shortly after mixing to take advantage of the expansion properties. Immediately after mixing pour or pump the mixed grout into the header box or hopper ensuring continuous grout flow during the complete grouting operation to avoid trapping air.

For large volume placement, grout pumps are recommended. Equipment trials should be considered to ensure product can be pumped satisfactory.

Surface finishing

Finish exposed grout surfaces to the required surface texture as soon as the grout has started to stiffen. Do not add additional water on the surface. Do not over work surface as this may cause surface discolouration and cracking. After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’.

Cold weather working

Consider using warm water to assist with achieving strength gain and maintaining physical properties.

Mechanical application of SikaGrout®-3170 R see "Ausrüstungsplaner Inotec Pumpe".

After pouring the surface must be protect against water evaporation and frost exposure until the sufficient strength has been achieved.

Suitable curing treatment:

• Water spray
• Foil covers with jute strips, thermal foils or moisturising cover strips
• Sika® Nachbehandlungsmittel NB 100

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed (at least 5 days).
