What happens here

Address any remaining cracks in the floor by first using a specialized crack chasing tool (as seen at 1:10) to open them up. This tool helps create a clean, V-shaped channel for proper filler adhesion. Many cracks were also offset or had old filler, necessitating this step. Following the chasing, hand grind the edges of the chased cracks to ensure a clean surface. Once prepared, fill the cracks with a suitable filler (like the liquid green material shown between 0:18 and 1:03), ensuring it penetrates deep into the crack and creates a smooth, level patch. This prevents the cracks from reappearing through the new floor coating.

Goal: Clean, prepare, and fill all floor cracks to create a stable and uniform surface.

What they say

Hide

bit raised over here, but it's a nice smooth transition. That was the biggest challenge of this side of the garage. There was cracks all over, and the cracks were uh kind of like offset a little bit. They were also filled with a filler, so used our crack chasing tool, chased them all, and then hand ground them before we ran our on-floor grinder over the top of them because they they're offset. Look at this.
