Beyem Plus NOx

Photocatalytic, with self-cleaning and decontaminating properties, extra white fine plaster.

About this product

BEYEM PLUS NOx  is a  photocatalytic, with self-cleaning and decontaminating properties, rainwater-proof extra white  plastering dry mortar, formulated with white cement, selected fine white aggregates, photocatalytic reagents and special additives. Fine finishing.

Benefits
  • Suitable for spray render and pump machines or manual applications.
  • Excellent whiteness
  • Good mechanical strengths.
  • Decontaminating and self-cleaning effect.
  • High workability.
  • Float/sponge/trowel  very fine smoothed finishes.
  • Rainwater-proof and permeable to water vapour.
  • Suitable for internal and external walls.
  • Easy and  fast application.
  • Factory produced for consistency of proportioning.
Use

Photocatalytic, mineral and rainwater-proof plaster for facades. Self-cleaning and decontaminating coating.

BEYEM PLUS  NOx degrades organic and inorganic substances deposited on its surface, which helps to maintain its aesthetic quality over time.

BEYEM PLUS  NOx reduces the concentration of most of the pollutants present in urban areas, turning harmful gases into compounds that are safe for health and the environment, through a natural process free of chemical agents.

Fine and extra-white finishing plaster to use over mortar undercoats.  Interior extra-white plastering. Suitable for  walls and ceilings  both in  interior and exterior situations, manually or mechanically. 

Substrates

BEYEM PLUS  NOx  is suitable for:

  • Renders and mortars undercoats.
  • Cement based substrates.
Preparation of substrates

Substrates must be clean, compact and  free of substances that reduce adhesion such as dust, oil, grease and with no loose material. Substrates must submit an adequate porosity and surface roughness. Dampen substrates with water  to cool down if they should be too warm, in case of wind or over absorbent substrates  and wait until the thin layer of water disappears. It is a good practice curing with a fine spray of clean water  24 h after application.

Do not apply on cellular concrete, gypsum based plasters, brickwork, paint, plastic, wood or materials with  low mechanical properties.

Instructions for use

Mix manually of mechanically BEYEM PLUS NOx with 5,0-6,0 l per bag of clean water until a homogeneous, creamy and lump-free paste  is obtained. Let the mix stand for 5 minutes before application.

To apply with render  spray machine, it´s necessary to set the relation water/mortar  and pump pressure depending on section and length of hose  and climatology conditions. It´s important to maintain the  variables affecting the properties of the applied mortar (distance to the wall, angle of application and water proportion). Spread the mixed product with a trowel (in case of manually or mechanically application) leaving  4-5 mm of average  thickness. Press to ensure adhesion and expel the air contained in the pores. Smooth with a ruler the applied material to regulate thickness. When BEYEM PLUS NOx  is green (set but not fully hardened) it should be  finished using a stainless steel trowel, wooden, plastic or sponge float according to the desired effect. 

Cautions and recommendations
Always mix with the specified amount of water.
Do not apply below 5ºC or above 30ºC.
Do not apply when there is  risk of frost, rain, strong wind or direct sunlight.
Above 5 mm of thickness, apply the product in two layers, leaving a roughness surface in the first to improve the adhesion of the second layer.
The minimum finishing thickness of system (Beyem Plus NOx + Base coat)  must be 10 mm, to contribute actively to the  waterproofing of surface.
Reinforcement with alkali resistant fiberglass mesh  may also be required, dependent upon substrate condition ( junctions of different surfaces, corners of voids…)  and project specification.
Expansion joints should be included as required by the substrate and respected by all applied materials.
It is necessary to use a primer on too high absorption substrates, as a cellular concrete, or on very low absorption substrates.
The photocatalytic properties of the mortar remain  whenever the surface of the coating is not covered.
The effectiveness of the photocatalytic process is influenced by the degree of exposure to light.
