Two men working with construction materials and a close-up of a power tool mixing a substance.

The video shows two men working with construction materials. The first man is mixing a substance with a power tool. The second man is holding a bag of white powder labeled 'KLEJ'. The third man is holding a bag of MAPEI Adesilex P9 Fiber Lite. The video then shows the substance being mixed in a bucket, followed by a close-up of a tile being applied with the substance using a trowel. Another shot shows tiles on a wall with leveling clips. The final sequence shows the two bags of MAPEI products and a third bag, with text overlay. The pacing is quick, with close-ups on the product and application process.
