THC 405 PLUS

FIBERPLUS THC 405 is a one-component, cement-based mortar modified with polymer additives. It is a specialized product recommended for bonding and plastering of thermal insulating plates like expanded polystyrene (EPS), extruded polystyrene (XPS) and mineral wool, in External Thermal Insulation Composite Systems (ETICS) for buildings. It consists of cement, quartz sand, limestone fillers and special additives. FIBERPLUS THC 405 presents a very strong attachment on all the usual substrates, high elasticity, resistance to frost and humidity. It is suitable to use both indoors and outdoors. It is categorized as a CS IV category mortar that meets the EN 998 European standard. The fiber-reinforced mortar FIBERPLUS THC 405 is part of the CLIMAPLUS external thermal insulation systems, which are CE-certified in accordance with the specifications of the EAD EAD 040083-00-0404.

• Suitable for strong bonding of: extruded polystyrene (XPS), expanded polystyrene (EPS), hard glass wool, cork.
• Suitable on substrates of concrete, light weight concrete, bricks, cement blocks, aerated concrete (AAC), self leveling floors, mortars and level masonry with filled joints.
• Can be used in combination with glass fiber mesh in order to cover the ts of different types of masonry (AAC or bricks with concrete, bricks with AAC, etc) to cover the conduits on masonry made by electricians and plumbers, to reinforce the edges of the openings (in doors and windows) in order to avoid future cracking of plaster

• Produced with quartz sand
• Single material for attachment and plastering of thermal insulating plates
• Local reinforcement of surfaces that develop cracking tensions
• Strong resistance to elastic deformation
• Strong adhesion
• Strong resistance – rapid application
• Resistance to humidity and frost
• Excellent workability
• Complies with EN 13499 & ETAG 004 European standards

• The application substrate must be even, free from frail and foreign parts, like residues of mud, plaster, color, oils and free from large crevices. Additionally, the substrate must be stable and free from shrinkage and deformation tensions. It also must not accept any vibrations. Place the plates’ guides and supports wherever it is necessary.
• In a clean container we add 6.0 liters of clean water and we gradually empty the content of a 25 kg of FIBERPLUS THC 405, while mixing continuously with an electrical agitator, in order to produce a homogenous mortar mass.
• The mixture is ready to use within the next 4 hours. After the preparation of the mixture, do not add additional water to correct the workability of the mortar. This shall lead to a decrease of its resistances and to an increase of its shrinkage.
• Application as adhesive:
  Application on level surfaces: FIBERPLUS THC 405 is spread on the thermal insulating plate using the even side of the spatula and the adhesive layer is then combed evenly with its toothed side.
  Application on uneven surfaces: FIBERPLUS THC 405 is spread with a towel around the perimeter of the thermal insulating plate and on the center point. We press the thermal insulating plate firmly on the wall in order to ensure the uniform contact of the adhesive. The final surface must be completely levelled. The open time is 15 minutes after the adhesive is applied. Any surplus adhesive must be removed from the joints. If the adhesive dries before the thermal insulating plate is applied, remove it and apply a fresh layer.
  Application as coating: After the adhesive has dried, we add the mechanical supports (plastic or metallic plugs) wherever it is necessary. We putty the plug holes, the plates’ joints and we install the corner beads and parts of the mesh in order to reinforce the edges of the openings. Then, we spread a uniform 2-4 mm thick layer of the FIBERPLUS THC 405 mortar on the thermal insulating plates using the “American Style Spatula” and we immediately install the glass fiber mesh, in a way that it covers the plates connections and overlaps the previous mesh by 10-15 cm. We press it using the spatula in order to integrate it in the adhesive layer and using the spatula, we add another thin layer of mortar 0.5-4 mm, in a way that it completely covers the mesh and provides an even surface.

On wooden palettes and in a dry environment with temperature above 0°C for 12 months from the production date.
