Biến sỏi thành sàn terrazzo

Vertical video in a bright empty room with white walls and a large window showing green trees outside. A man in blue overalls rakes a huge pile of glossy orange pebbles on the bare concrete floor, spreading them evenly across the entire room. Workers in red overalls pour white self-leveling epoxy resin from buckets over the pebbles, then spread it with squeegees and paint rollers until the surface is flat, smooth and glossy. Time-lapse of a worker in a yellow hi-vis vest and respirator grinding the cured floor with a polishing machine, revealing a terrazzo-like surface dotted with round orange pebbles. Fast time-lapse of room assembly: a wooden bed frame is built, dressed with white bedding and beige pillows, a nightstand with a lamp is added and framed abstract art hangs on the wall. Final static shot of a cozy finished bedroom with the polished orange pebble floor shining in soft natural daylight. Photorealistic, satisfying renovation time-lapse, smooth camera movement, warm natural lighting.
