B1 CONSTRUCTION PLASTER (UNE-EN 13279-1)

MECAGYPS® N is single-layer mechanical projection plaster indicated for interior trim of walls and ceilings. Due to its high surface hardness it is suitable for corridors, schools, hospitals, etc.

HOW TO USE
– Prepare the surface ensuring it is free of dust and loose particles, rough spots, oil stains and other residues that may reduce its adhesion.
– It is recommended to moisten the application surface with water or apply a regulating primer if the absorption of the surface is very high.
– In the case that the support is too smooth, a product that favours adhesion should be applied.

APPLICATION
– Project regulating the flow of water to obtain a consistent and workable paste.
– Smooth using an aluminium ruler to obtain a flat surface.
– Small imperfections may be cut off using a steel blade.
– Apply MAX FINE for the perfect finish.

APPLICATION CONDITIONS
– The recommended thickness of the coat is between 1cm-2cm.
– The temperature during application should not be lower than 5ºC or above 40ºC.
– The relative humidity should not exceed 70%.
