ALLTEX / KNAUF APPLICATION
The most efficient method of application if by use of a spray-unit which is powered by an electric (380 volt) or pneumatic motor (air).
The ALLTEK / KNAUF bag is placed on the wringer/mangle of the machine and by turning the handle the bag is easily emptied into the hopper. Air and electricity is connected and the control set at desired speed and air-pressure. |

Interior building surfaces of walls and ceilings would be built "FAIRFACED". Joints between cement blocks and/or panels would be "flushed out" by the builder as work proceeds and all excess and droppings scraped off to leave a reasonable smooth and level surface without protrusions. |

|
Spraying can now start and is done in an even layer to the entire ceiling/wall area. |
|
|
External corners are fitted with a thin-coat corner bead to give good appearance and protection. The bead is simply pressed into the ALLTEK / KNAUF material and will thus be bonded to the corner. |
|
|
Leveling commences directly after the spraying and is done using a special steel-edged spatula tools. The ceiling is leveled from the floor using a spatula fixed to an extension handle. - Excess material is removed and returned to the spray-unit for re-use. |

After drying, normally the following day, a second coat is applied, the ceilings can be sprayed as a "TEXTURE" finish which will also act as an acoustics barrier. Walls are normally leveled smooth unless a texture is wanted also here.
The average rate for a two man team is 200-500m² of single coat per day. Surfaces up to 3m above floor level can be treated without using platforms or scaffolding.
Painting can generally be done within 24-48 hours of the last coat of ALLTEK / KNAUF.
