Mineral and rainwater-proof one coat mortar for facades, brickwork and  concrete block enclosures. Rough and scraped finishes. Suitable for  walls and ceilings  both in  interior and exterior situations, manually or mechanically. New construction and rehabilitation. Through coloured for low maintenance.

Especially suitable for finishing Beyem Aislaterm thermal insulation system. 

BEYEM  COLORTERM s suitable for:

• Brickwork. Ceramic bricks.
• Beyem Aislaterm thermal insulation mortar.
• Concrete blocks.
• Concrete  (treated with BEYEM UNIÓN MORTEROS adhesion promoter primer).
• Cement based substrates and lime-cement based 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. Uneven areas must be corrected.  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, paint, plastic, wood or materials with  low mechanical properties.

Mix manually of mechanically BEYEM COLORTERM with 5,5-7,0 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  12-15 mm of average  thickness, after marking the pieces by using PVC splines. Press to ensure adhesion and expel the air contained in the pores. Smooth with a ruler the applied material to regulate thickness. When BEYEM COLORTERM is green (set but not fully hardened) it should be scraped with a circular action using a scarping tool. To avoid changes in tone always carry out this procedure at the same hardening point. Thoroughly brush down the surface of the scraped finish using a soft bristle brush. 

• 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 15 mm of thickness, apply the product in two layers, leaving a roughness surface in the first to improve the adhesion of the second layer.
• It is not advisable to apply on horizontal or sloped surfaces. 
• Proteger las aristas superiores del revestimiento  frente a la penetración del agua de lluvia.
• The minimum finishing thickness of render 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.
• Demarcate pieces of work using PVC battens previously placed.
• 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.
• Variations in weather conditions during application, and the application in several phases can produce changes in tone.

BEYEM COLORTERM is packed 25 kg plastic lined paper bags.

Storage:  when stored unopened in a cool dry place, shelf life is 12 months from date of manufacture.

Tools can be cleaned easily with water  before the product hardens. Hardened product can be remove only mechanically.

Finishing of Beyem Aislaterm thermal insulation system with scraped or rough coloured render, must be carried out with lightweight, rainwater-proof, one coat dry mortar  compliant with EN 998-1- Class OC CSIII W_c 2, such as Beyem Colorterm manufactured by Rodacal Beyem Company. Coverage will be ≈ 12 kg/m² per cm of  thickness. The substrate must be clean, sound, compact and dimensionally stable. Expansion joints must be respected.
