Spal-Pro RS 88 should be installed full joint depth in saw-cut contraction/control joints (or 2” minimum in saw-cut joints exceeding 2” in depth) per PCA and ACI guidelines

In construction (formed) joints that are not saw-cut, Spal-Pro RS 88 should be installed at a minimum 2” depth. DO NOT USE COMPRESSIBLE BACKER ROD IN STANDARD SAW-CUT CONTRACTION/CONTROL JOINTS! Should not be installed prior to 30 days to ensure adequate adhesion.Joints should be completely free of saw laitance, dirt, debris, coatings/sealers and frost or visible moisture. Joints can be filled in one or two passes, Slightly overfill the joint, leaving a crowned profile, and allow to cure

When sequencing product installation as part of a concrete grinding/polishing process, installation can be done prior to grinding/honing if the first tool used is to be 40 grit or higher. Installation can also be deferred until prior to the last metal or transitional tooling step. The earliest the installed filler should be subjected to honing is 30 minutes if using a wet process, 3-4 hours if using a dry process (at 70°F)
