What happens here

Before starting any filling work, it's crucial to understand the different types of joints in concrete. "Control joints" (also known as saw cuts) are intentionally placed in concrete during curing to control where cracks form due to shrinkage. These can generally be filled once the concrete is fully cured and stable. "Expansion joints," "cold pours," or joints around structural support beams are designed to allow for significant movement and should typically not be filled before applying a coating system, as honoring these joints is critical for the structure's integrity. The video's expert explains this distinction, clarifying that control joints in places like garages are suitable for filling to achieve a seamless look.

Goal: Identify which concrete joints are suitable for filling.

Now, the question is, is it wrong or is it right or okay to fill a saw cut? >> That's the time and there's so much misinformation out there. That control joint that is put in the concrete when it's curing is designed to control when the concrete's shrinking and the cracking. And if you look down in that control joint, usually you see that's where your crack is. We can't see it here cuz you did a great job filling it. Control joints, absolutely once that window of the concrete curing, depending on how thick it is, is over, they can be filled, grinded, shaved flush, whatever system you're using, and then they can be coated over the top. It's expansion joints, cold pores, joints of that nature, maybe it's a structural support beam that you wouldn't want to fill before a coating system. Those ones should be honored, but your control joints, which are in almost every garage, can certainly be fixed and
