Dust and rubble should be swept up and vacuumed. Next damp wipe or mop the surface to ensure that the surface is as clean as possible. A clean surface will allow your waterproofing treatment to adhere to the surface and create an effective waterproof barrier.
Make sure you check the waterproofing product data sheet to ensure optimal installation and coverage.
