GROUTING PROCEDURE FOR THE SLEW RING UNDERSIDE.
THE INSTRUCTIONS SET OUT ARE FOR THE APPLICATION OF EPIREZ 386 TWO PART EPOXY GROUT AND MUST BE DONE IN ACCORDANCE WITH THE MANUFACTURERS INSTRUCTIONS. AS MIXED GROUT CURES AND HARDENS RAPIDLY IN HIGHER TEMPERATURES ALL WORK SHOULD BE CAREFULLY PLANNED AND QUICKLY AND SKILLFULLY EXECUTED.
IT WILL BE BENEFICIAL TO MAKE A SMALL TRIAL DAM TO CHECK THE CURING RATE BEFORE PROCEEDING WITH THE RING GROUTING.
1. CLEAN RUST, PAINT, MILL SCALE ETC. BY ROUGH HAND GRINDING OFF SURFACE TO BE GROUTED.
2. BUILD DAM BY GLUEING 2 FOAM RUBBER STRIPS TO DIMENSIONS SHOWN ON DETAIL. USE CONTACT ADHESIVE. NOTE THAT THE RUBBER SHOULD NOT BE UNDER THE SLEW RING.
PLUG THE BOLT HOLES WITH FOAM RUBBER PROJECTING 10mm ABOVE THE FLANGE.
3. FIT 6 JACKING SCREWS IN THE TAPPED HOLES PROVIDED. USE 3 SCREWS TO INITIALLY LEVEL THE RING 10mm ABOVE THE SUPPORT FLANGE. WHEN THE RING IS LEVELLED RAISE THE ADDITIONAL 3 SCREWS TO TOUCH THE RING AND RECHECK LEVEL. GREASE SCREW THREADS WITH VASALINE OR SIMILAR TO PREVENT THE GROUT BONDING TO THE THREADS.
4. LIFT UP RING AND GREASE UNDERSIDE OF RING TO PREVENT IT FROM BONDING TO GROUT. RETAIN THE RING ABOVE THE FLANGE SO THAT IT CAN BE LOWERED IN MINIMUM TIME AFTER THE GROUT IS POURED. TO ASSIST 2 OR 3 TAPERED GUIDE DOWELLS WILL ASSIST GREATLY.
5. CALCULATE THE VOLUME OF GROUT TO BE POURED AND MIX THIS AMOUNT USING AT LEAST 3 PEOPLE TO MIX AND POUR THE GROUT SIMULTANEOUSLY. THE GROUT IS TO BE MIXED TO THE MANUFACTURERS INSTRUCTIONS AND SHOULD NOT BE DONE WHEN THE SUN IS HEATING THE BASE FABRICATION AS THIS WILL DISTORT THE BASE RING.
6. FILL THE DAM UNTIL THE LEVELLING SCREWS ARE JUST COVERED, SMOOTH OFF AND IMMEDIATELY LOWER THE RING INTO PLACE.
7. WHEN THE GROUT STARTS TO SET LOWER THE JACK SCREWS 1 TURN AND LEAVE THE RING SITTING IN PLACE UNTIL THE EPOXY IS CURED.
8. RAISE THE RING TO CHECK THE GROUT AND IF IT IS SATISFACTORY REMOVE THE FOAM RING STRIPS. PLUGS AND DOWELLS. GRIND OFF OVERFLOW GROUT, CLEAN THE RING AND CONCLUDE RING INSTALLATION.
