BEYEM B-P is a lightweight rainwater-proof one coat mortar for decoration of facades. Formulated with white cement, selected and lightweight aggregates, special additives, and inorganic pigments.
It allows constant hygrometric exchange between the substrate and the environment. Especially suitable for projected aggregate finishing.
Mineral and rainwater-proof one coat mortar for facades, brickwork and concrete block enclosures. Projected aggregate and textured finishes. Suitable for walls and ceilings both in interior and exterior situations, manually or mechanically. Through coloured for low maintenance.
BEYEM B-P is suitable for:
- Brickwork. Ceramic bricks.
- Concrete blocks.
- Concrete (treated with BEYEM UNIÓN MORTEROS adhesion promoter primer).
- 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 B-P with 6,5-7,5 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 10-16 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.
Projected aggregate finish: Once the surface has been levelled and before the superficial coat is dry (between 10-40 min), apply the chosen aggregate and press with the trowel to achieve the same level for aggregates and mortar.
Textured finish: The modeling work will be done with the right tool when the product begins to harden, taking into account the sculpture and decorated to make. It is advisable to use a release agent to improve the ease of separating stamp and texturing tools from the freshly placed mortar. To avoid changes in tone always carry out this procedure at the same hardening point.
BEYEM B-P 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.
Coloured rendered surfaces with projected aggregate finish, must be carried out with lightweight, one coat dry mortar compliant with EN 998-1- Class OC CSIV Wc2, such as Beyem B-P manufactured by Rodacal Beyem Company. Coverage will be ≈ 13 kg/m2 per cm of thickness. The substrate must be clean, sound, compact and dimensionally stable. Expansion joints must be respected.
