SikaFlow-648 is a three-component low-dust epoxy precision grout for aligning compressors, pumps, motors, and other critical equipment. It pours or pumps under a baseplate while low creep holds alignment.
SikaFlow-648 is a three-component low-dust epoxy precision grout for aligning compressors, pumps, motors, and other critical equipment on industrial bases. It pours or pumps from 1/2 in to 6 in, holds low creep for alignment, and keeps working time long enough for careful placements around live equipment. The 1.7 cu ft kit is the unit stocked here for full machinery pours.

What makes SikaFlow-648 a low-dust epoxy grout?
The aggregate and formula are built for low dust generation during mixing and placement, which improves worker comfort around precision equipment pours.
What placement thickness suits SikaFlow-648 under a plate?
Typical placement is 1/2 in minimum up to 6 in. Contact Sika Technical Service before lifts thicker than 6 in.
What pot life does SikaFlow-648 have at 70 F?
Approximately 90 to 120 minutes at 70 F. At 90 F pot life shortens to approximately 50 to 60 minutes; at 50 F it extends to approximately 120 to 150 minutes.
What creep performance matters for SikaFlow-648 alignment?
Low creep is the reason contractors pick this precision epoxy under compressors, pumps, and motors that must stay aligned under continuous load.
What kit size is stocked for SikaFlow-648?
This page is the approximately 1.7 cu ft kit. The PDS also lists a smaller 0.4 cu ft unit that is not the primary stock here.
What cleanup works on uncured SikaFlow-648?
Uncured material cleans with soap and water per the PDS. Once cured, mechanical removal is required.
