Apply Polyurea Filler

What happens here

Once the saw cuts and cracks are clean and prepared, fill them with a suitable polyurea filler. The video specifically mentions using "Fortification from Citadel" polyurea filler mixed with sand. Pour or apply the filler directly into the cuts and cracks, ensuring they are completely filled. Use an appropriate tool, like a spatula or trowel, to smooth the filler and press it into the joint, creating a slightly overfilled mound that can be later ground flush. The video shows a worker kneeling, pouring a dark filler into the joints, and smoothing it with a tool.

Goal: Completely fill saw cuts and cracks to prepare for a seamless surface.
