The above limitations are not absolute. Equipment trials must be considered to ensure product can be pumped satisfactory.

MIXING

SikaGrout®-3620 must be mixed using suitable grout mixing equipment combined with agitator for continuous large volume mixing. Volume capacity of equipment must be applicable to the volume of material being mixed for a continuous operation. Equipment trials must be considered to ensure product can be mixed satisfactory before full project application.

Pour the correct proportion of water into the grout mixer. While stirring the water, slowly add the powder to the water.

Mix continuously until the grout achieves a lump free smooth consistency. Do not add more water than the maximum specified.

 

APPLICATION

Placing: Grout pump application

Equipment trials must be considered to ensure product can be pumped satisfactory.

Note: After application, do not disturb grout until it is sufficiently hardened.

Cold weather working

Consider storing bags in a warm environment and using warm water to assist with achieving strength gain and maintaining physical properties.

Hot weather working

Consider storing bags in a cool environment and using cold water to assist with controlling the exothermic reaction to reduce cracking and maintaining physical properties.

CLEANING OF EQUIPMENT

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