Grouting Preparation and Application


SURFACE: Clean thoroughly, free of loose and unsound material, remove any cement slurry by means of hydraulic water-blasting or similar until carrying capacity of grain structure is reached. Sufficient adhesion must be granted (i. m. > 218 PSI). Prior to grouting, the surface must be wetted continuously for approx. 6 hours until saturation.
FORMWORK: Must be of rigid construction, with sand or dry mortar being placed around the concrete base carefully to prevent leakage.
MIXING: The grout is ready for use, only water is to be added. Measure out the correct quantity of water and fill two thirds of this into a concrete mixer or bucket, add the dry mortar and mix for about 3 minutes. Then fill in the remaining water and mix for another 2 minutes. Grouting then should take place immediately.
GROUTING: Place the mixed grout from one side or corner in one continuous pour. When grouting large areas we suggest to pour starting from the middle – using a pipe or funnel. On machine installations fill the anchor bolt pockets first (up to approximately top of anchor bolt pockets) and then the underside of the machine. Working time: approx. 120 minutes.
CAUTION: Open areas must be protected against wind, drafts and premature evaporation by using plastic sheeting or O1 PAGEL-CURING AGENT.
GROUTING SHOULDERS: Heights and shoulders around base plates must not exceed 2 inches or 50 mm.
TEMPERATURE: Application between 41°F and 95°F (5°-35°C), low temperature working conditions retard the strength development and reduce the flowability while high temperatures accelerate the same.
NON-IRON METALS: Cement as well as all cement-bound building materials may under certain circumstances cause a reaction with non-iron-metals in the application area (for example aluminium, copper, zinc). Please ask for our technical assistance.
