THC 410 C

Coarse grained, fiber reinforced, polymer modified, cement based mortar. It consists of cement, quartz sand with 1.5 mm max. grain size, limestone fillers and admixtures. It complies with EN 13499 and ETAG 004. Suitable for bonding and plastering.

• THC 410C product is used as an adhesive and as a basic layer plaster for thermal insulating plates for the outdoor thermal façade system (ETICS) of THRAKON.
• The THC 410C adhesives can be used in combination with fiber glass mesh in order to cover the connections between different types of masonry (aerated concrete with concrete, bricks with aerated concrete, etc.), to cover the conduits on the masonry made by electricians and plumbers, to reinforce the edges of openings (in doors and windows) in order to avoid future cracking, etc..
• For the strong bonding of: extruded polystyrene (XPS), expanded polystyrene (EPS), hard glass wool, cork

• It is produced with quartz sand
• A single material for attachment and plastering of thermal insulating plates
• It is reinforced with polypropylene fibers
• Suitable for the local reinforcement of the surfaces that develop strong cracking tensions during plastering.
• Strong resistance to elastic deformation
• Strong adhesion
• Strong resistance
• Resistance to humidity and frost
• Excellent workability
• It complies with EN 13499 and ETAG 004 European standards
• Rapid application

• In a clean container we add  5.5 litres of clean water for adhesion of thermal insulating plates  6.0 litres of clean water and we gradually empty the content of a 25 Kg bag of the THC 410 product while mixing continuously with an electrical agitator, in order to produce a homogenous mortar mass. Allow the produced mixture to mature for 5 minutes and briefly reagitate. 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 will result to a decrease of its strengths and to an increase of its shrinkage.
• Application as adhesive | Application on level surfaces: THC 410C is spread on the thermal insulating plate using the even side of the spatula and the adhesive layer is then combed uniformingly with its toothed side.
• Application on uneven surfaces: THC 410C is spread with a trowel around the perimeter of the thermal insulating plate and on the centre 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 application of the adhesive. 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 mesh in order to reinforce the edges of the openings.
• Then, using the “American type spatula” we spread a uniform THC 410C mortar layer with a thickness of 2-4mm on the thermal insulating plates, and we immediately install the glass fiber mesh, in a way that it covers the plates connections and overlaps the previous mesh by 10-15cm.
• We press it using the spatula in order to integrate to the adhesive layer and using the spatula we add another thin mortar layer 0.5-4mm, in a way that the mesh is completely covered and an even surface is provided.
• During the application and also during the following 24 hours the ambient and the substrate temperature must be between +5 ºC and +35 ºC.
• The adhesive can be cleaned with water while it is still moist.
• After it hardens, it is removed mechanically.
• After the mortar has dried completely, we apply the final decorative plaster using one of the decorative coats of THRAKON.

The product is packaged in 25Kg in a dry environment with temperature above 0ºC for 12 months from the production date.
