Ever noticed your diamond blade cutting slower, producing smoke, or leaving rough edges? That doesn't always mean it's worn out — it might just be glazed. In that case, what you really need is blade dressing, sometimes called "opening" or "conditioning" the blade. This process restores your blade's cutting power by exposing new, sharp diamond particles and clearing away metal buildup from the bond.

You should cut control joints in concrete to a depth of about one-quarter to one-third of the slab’s total thickness. This depth ensures that the joint effectively controls cracking as the concrete cures and contracts. For instance, if you’re working with an 8-inch concrete slab, the saw cuts should reach approximately 2 to 2.7 inches deep. Maintaining this ratio helps direct shrinkage stress into the joints, minimizing the risk of random or uncontrolled cracks across the surface.
