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. It may be dry or damp, but free of standing
water. 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. 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 100 mm (4 in) 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.
Mix the entire contents of components A and B in the component A pail for 3 min with a paddle attached to a low speed drill
(200-250 rpm). Place the mixed epoxy into an appropriate mixer. Slowly add the contents of component C depending
on flow required and mix until uniformly blended (approx. 5 min). When mixing the first batch of the epoxy adhesive
grout system in a clean and dry mixer, withhold 10 kg (22 lb) of component C to charge the mixer. Mixed grout should
be kept agitated just prior to placement.
Pour the mixed grout into the prepared forms from one or two sides only, to eliminate air entrapment. Maintain the liquid head
to ensure intimate contact to the base plate. Place sufficient epoxy grout in the forms to rise slightly above the underside [3 mm
(1/8 in)] of the base plate. The minimum void depth beneath the base should be 25 mm (1 in). Where the void beneath
the base plate is greater than 150 mm (6 in), place the epoxy grout in successive 150 mm (6 in) lifts or less, once the
preceding lift has cooled.
Sweep into appropriate containers. Dispose of in accordance with applicable local regulations. Uncured material can
be removed with Sika Equipment Cleaner/Epoxy Thinner. Cured material can only be removed mechanically.
■ Minimum substrate temperature: 16°C (61°F).
■ Grouting material must be stored in an area with an ambient temperature between 20°- 30°C (68° - 86°F) for a
minimum of 48 hours before using.
■ Do not thin with solvents. Solvents will prevent proper cure.
■ Material is a vapour barrier after cure.
■ Minimum grout depth: 25 mm (1 in).
■ Maximum grout depth: 150 mm (6 in) per lift.
■ Component C must be kept dry.
■ For bolt grouting applications contact Sika Technical Service.
■ For proper seating, allow grout to rise above the bottom [3 mm (1/8 in)] of the base plate.
■ Do not batch. Mix complete units only.
■ Cold ambient, substrate or material temperatures will inhibit the curing and flow characteristics of Sikadur 42 Grout
Pak.
■ Do not subject cured epoxy grout to sudden temperature changes especially during early curing stages.
■ Contact Sika Technical Service for control joint spacing on large base plate grouting projects.
Component A - Irritant - Prolonged contact to skin may cause irritation. Avoid eye contact.
Component B - Irritant - Contact with skin may cause severe burns. Avoid eye contact.
Component C - Contains silica. Avoid breathing dust. Product is a strong sensitizer. Use of safety goggles and
chemical resistant gloves recommended. Avoid breathing material. Use adequate ventilation. Use of a NIOSH/MSHA
organic vapour respirator recommended. Consult product label for additional information.
In case of skin contact, wash with soap and water. For eye contact flush immediately with plenty of water for at least
15 min. Contact a physician. For respiratory problems, transport victim to fresh air. Remove contaminated clothing
and wash before re-use.
