BEYEM S AR M-25 is a high strength rendering dry mortar and projectable thixotropic micro-concrete, formulated with high resistance cement, selected aggregates and special additives to improve workability, and adhesion. Available in fine and thick version.
High strength rendering works. Especially suitable for construction systems with structural panels as ICFs (Insulating Concrete Forms). Works in farms, swimming pools and fillings. Support of slopes and reinforced surfaces. Basecoat for theming and modeling works when large volumes and/or armors are necessary. General purpose masonry mortar when high resistance is required. Suitable both in interior and exterior situations.
BEYEM S AR M-25 is suitable for:
- Concrete (treated with BEYEM UNIÓN MORTEROS adhesion promoter primer).
- Cement based substrates.
- Insulating Concrete Forms (ICFs).
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, paint, plastic, wood or materials with low mechanical properties.
Mix manually of mechanically BEYEM S AR M-25 with 3,75-4,75 (Fine) or 3,25-4,25 (Thick) 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 10-15 mm (Fine version) or 25-40 mm (Thick version) of thickness per layer. Press to ensure adhesion and expel the air contained in the pores. Smooth with a ruler the applied material to regulate thickness. When BEYEM S AR M-25 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.
BEYEM S AR M-25 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.
High strength rendering works, must be carried out with rendering dry mortar compliant with EN 998-1- Class GP CSIV Wc 1, such as Beyem S AR M-25 manufactured by Rodacal Beyem Company. Coverage will be ≈ 20 kg/m2 per cm of thickness. The substrate must be clean, sound, compact and dimensionally stable. Expansion joints must be respected.
