How do you prepare a room before spraying foam?

Surfaces should be properly prepared before they can be insulated.
They should be free of dust, oil, loose elements, and other agents that may reduce foam adhesion.
Due to the chemical reaction taking place during the construction works, it is advisable to remove all unnecessary items from the rooms where the insulation is to be sprayed in order to prevent the characteristic smell from lingering.
Companies providing thermal insulation services usually secure windows, doors, and other objects exposed to dirt themselves.
The investor is responsible for the preparation of all installations in spraying areas, such as electrical conduits and ventilation systems.
If plasterboard will be used, it is good to install framing hangers/mounts in advance and to prepare roof windows and hatches.
