Beyem Termoacústico

BEYEM TERMOACÚSTICO is a polymer-modified, rainwater-proof, shrinkage compensated adhesive and basecoat mortar for fixing EPS insulating panels in cavity walls for thermo-acoustic systems. Formulated with high strength grey cement, selected aggregates, special additives and synthetic resins  to improve plasticity, adhesion, rainwater-proofing and an excellent workability.

• Suitable for spray render and pump machines or manual applications.
• Good mechanical strengths.
• High  bond strength on EPS panels.
• Good open time. Allows adjustement.
• Applicable  directly to the building enclosure.
• High workability.
• Rainwater-proof and permeable to water vapour.
• High deformability.
• Non  slip.
• Easy and  fast application.
• Factory produced for consistency of proportioning.

Fixing  EPS panels for thermo-acoustic insulation systems with contribution to waterproofing in cavity walls (both double brickwork with cavity and exterior brickwork with self-supporting boards with intermediate cavity). Mineral render. Allows the plastering of insulation panels. Suitable for spray render and pump machines or manual applications. Projectable. BEYEM TERMOACÚSTICO allows the double function of contributing to the impermeability of the wall and fixing of EPS insulation panels by adhesion.

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 gypsum based plasters, paint, plastic, wood or materials with  low mechanical properties.

Mix manually of mechanically BEYEM TERMOACÚSTICO  with  4,75-6,25 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 mm of maximum  thickness. Smooth with a ruler or a trowel the applied material. Set the insulating panel over fresh mortar and press to ensure adhesion. If necessary, EPS panels can be covered (plastered) with the same material.

• 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.
• Do not apply to areas where there is a possibility of stagnant water.
• Above 5 mm of thickness (rendering), apply the product in two layers.
• Reinforcement with alkali resistant fiberglass mesh (rendering)  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.

BEYEM TERMOACÚSTICO 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.

Bonding of  EPS panels for thermo-acoustic systems must be carried out with rainwater-proof basecoat render and adhesive compliant with EN 998-1- Class GP CSIV W_c2, such as Beyem Termoacústico manufactured by Rodacal Beyem Company. Coverage will be ≈ 1,4 kg/m² per mm of  thickness. The substrate must be clean, sound, compact and dimensionally stable. Expansion joints must be respected.
