MIXING
SikaGrout®-3200 shall be professionally mixed using suitable mixing equipment applicable to the volume of material being mixed. Pour the minimum water ratio in the correct proportion into a suitable mixing container. While stirring slowly, add the powder to the water. Add more water within the mixing time up the maximum allowed until the desired consistency is achieved and to suit ambient temperature conditions. Do not add more water than the maximum specified. Mix thoroughly for minimum 3 minutes. For larger mixes the mixing time shall be extended to approximately 5 minutes or as necessary until the mortar is homogenously mixed with no lumps and no remaining dry powder.
APPLICATION
Pre-Wetting The concrete substrate shall be thoroughly saturated with clean water a recommended 12 hours before application of the grout. The surface shall not be allowed to dry in this time. Prior to application of the grout, excess water shall be removed and the surface shall achieve a dark matt appearance (saturated surface dry) without glistening and surface pores and pits shall not contain water.
SikaGrout®-3200 is applied manually using traditional pouring techniques or for large applications using suitable pumping device (refer to Sika Technical Service for advice). It is recommended to check the material after pumping.
Apply the material shortly after mixing to take advantage of the expansion properties.
Ensure formwork is strong enough to hold the fresh mortar and sealed to prevent leakage.
Cure exposed surfaces immediately with protective sheet or membrane. Shield the fresh mortar from direct sun, wind and frost. Finish exposed surface as desired as soon as the mortar has started to stiffen. Do not add additional water on surface. Do not over work surface as this may cause surface cracking.
CURING TREATMENT
Protect the fresh mortar from early dehydration using the relevant curing method.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
