Beyem R1 T Renodur

BEYEM R1 T RENODUR  is a one-component, highly deformable, low shrinkage, thixotropic mortar for mortar for repair and renovation of walls. Formulated with special cements, selected aggregates, organic additives and resins to improve adhesion and mechanical strengths. Lightweight and fiber-reinforced. Specially suitable for rendering walls in rehabilitation works (paints, ceramic tiles, etc …) and for the treatment of cracks in facades.

• Class R1 and GP CSIV W_c2.
• Modified polymer mortar (PCC).
• High mechanical strengths.
• High adhesion.
• High deformability.
• Lightweight. Great plasticity.
• Ideal as support for acrylic mortars and silicone paints.
• Free of chlorides and organic fibers.
• Suitable for pump machines and manual applications.
• Both internal and external use. Surface ready to paint.

Thin  layer deformable render  for  rehabilitation of facades and stable and anchored coatings. Levelling and smoothing of painted surfaces, vitreous mosaics and ceramic tiles well fixed  to the substrate. Bonding bridge and cementitious primer for rendering  mortars and acrylic mortars on low absorption substrates. Treatment of cracks in facade. Cosmetic repair of concrete according to EN 1504-3 Class R1. Beyem R1 T RENODUR is an anti-cracking system in combination with flexible and / or deformable coatings.

BEYEM R1 T RENODUR is suitable for:

• Concrete and  precast concrete  elements.
• Mortars and other cement based substrates.
• Paints and other synthetic coatings compact and well anchored to the substrate.
• Fiber-cement panels.
• Ceramic tiles and vitreous mosaic tiles well  fixed to the substrate

Substrates must be free from dust, loose material, surface contamination and materials which reduce  bond or prevent suction or wetting  by repair materials. Where necessary, concrete  must be cleaned by sandblasting, high pressure water jetting or other approved mechanical methods that do not cause vibration or impact, to leave a clean and keyed surface. Absorbent substrates should be previously wetted until they are saturated, preventing waterlogging, and applying the mortar  once the surface has a matt appearance. Smooth, slightly absorbent or very damaged substrates should be treated to obtain a surface with minimum guarantees of roughness and tensile strength. For more information regarding substrate preparation, refer to the recommendations provided in EN 1504-10.

On mortar substrate, in case of heat or wind and/or high absorption, the substrate must be wetted as indicated above, as well as conveniently cure the applied product 24 hours after the application. Non-absorbent supports must be perfectly dry.

It can be applied without the need of bonding bridge/primer over concrete, mortar, ceramic, stone, well adhered paint, well adhered acrylic mortars, vitreous mosaic, etc …

Mix manually of mechanically BEYEM R1 T RENODUR with 5,0-5,5 l per bag of clean water until a homogeneous, and  and lump-free paste  is obtained. 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  2-6 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. Finishing for both hand and machine application can be done with the same trowel or float as soon as the mortar has started to stiffen. When the material is used on highly absorbent surfaces, apply a minimum thickness per 5 mm layer. Respect the correct application techniques.

• Do not apply below 5ºC or above 30ºC.
• Do not apply when there is risk of frost, rain, strong wind or direct sunlight.
• Do not add water in excess of the recommended dosage .
• Do not use for structural reinforcement.
• Protect the mortar applied of early dehydration, using suitable  curing methods. The curing operation in humid environment is essential for at least 24 hours after application.
• Mix only sufficient material that can be applied  using available labour and equipment.
• Do not add cement, sand or other substances that may affect the properties of the material.
• Do not apply on silicone paints/coatings. Respect expansion and structural joints. Do not apply on gypsum, metal or wood.

BEYEM R1 T RENODUR 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 removed only mechanically.

Rehabilitation of facades and stable and anchored coatings, levelling and smoothing of painted surfaces, vitreous mosaics and ceramic tiles well fixed  to the substrate and treatment of cracks in facade  must be carried out with one-component, highly deformable, thixotropic, low shrinkage, fiber-reinforced mortar for repair and renovation of walls compliant with EN 1504-3 – Class R1 and EN 998-1 –Class GP CSIV W_c2 and according to Principle 3, method 3.1 and 3.3, and Principle 7 methods 7.1 and 7.2 of the EN 1504-9, such as Beyem R1 T Renodur, manufactured by Rodacal Beyem Company. Apply in a minimum thickness of 2 mm per layer or 5 mm per layer in the case of highly absorbent substrates. Coverage will be  ≈ 1,4 kg / m2 per mm of thickness.
