SUBSTRATE PREPARATION
Note: For optimum results when grouting in critical items of equipment, it is recommended that the surface preparation requirements of the latest edition of Chapter 5, API Recommended Practice 686 be followed. This document is the “Recommended Practices for Machinery Installation and Installation Design” published by the American Petroleum Institute.
Surface and base plate contact area must be clean and sound. For best results, the substrate should be dry. Remove dust, laitance, oils, grease, curing compounds, impregnations, waxes, foreign particles, coatings, and disintegrated materials by mechanical means, i.e. chipping with a chisel, sandblasting. All anchor pockets or sleeves must be void of water. Sandblast metal base plates to a commercial white finish (SP-10) for maximum adhesion. Apply grout immediately to prevent re-oxidizing.
Forming: The consistency of the epoxy grout system requires the use of forms to contain the material around the base plates. In order to prevent leakage or seepage, all forms must be sealed. Apply polyethylene film or wax to all forms to prevent adhesion of the grout. Prepare form work to maintain more than 4 in. (100 mm) liquid head to facilitate placement. A grout box equipped with an inclined trough attached to the form will enhance the grout’s flowability and minimize air encapsulation.
MIXING
Thoroughly stir both Component A and Component B, distributing any settled solids and achieving an even consistency throughout each component. Mix the entire contents of components A and B in the component A pail for 3 minutes with a paddle attached to a low speed drill (300–450 rpm). During the mixing operation, scrape down the sides and bottom of the mixing pail with a flat or straight edge trowel at least once, to ensure complete mixing of A and B components. Empty entire contents of mixed A and B components into an appropriate mortar mixer ensuring that walls and bottom of mixing pail are scraped clean and all of mixed epoxy resin is added to mortar mixer. Slowly add the entire content of component C and mix until uniformly blended (approx. 5 minutes). Add all component C unless a reduction is directed by the Sika Representative. Mixed grout should be kept agitated prior to placement.
CLEANING OF TOOLS
Sweep into appropriate containers. Dispose of in accordance with applicable local regulations. Uncured material can be removed with Sika® Equipment Cleaner. Cured material can only be removed mechanically.
