BEYEM PLUS is a rainwater-proof extra white plastering dry mortar, formulated with white cement, selected fine white aggregates and special additives. Fine finishing.
- Suitable for spray render and pump machines or manual applications.
- Excellent whiteness
- Good mechanical strengths.
- 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.
Mineral and rainwater-proof plaster for facades. 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.
BEYEM PLUS is suitable for:
- Renders and mortars undercoats.
- 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. 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.
Mix manually of mechanically BEYEM PLUS 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 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.
- 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 + 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.
