General description of the system
This short description introduces the Thermomaster external thermal insulation composite system and its components. This product catalogue and THERMOMASTER® Instruction Guidline issued by MASTERPLAST GROUP provide more detailed information about the system.
Components and structure of the THERMOMASTER® A02 EPS system:
Components and structure of the THERMOMASTER® A02 Stone-wool system:
Before the start of construction works, the building must be examined: the material and the thickness of the wall, the potential thermal bridges and their positions, the quality and moisture content of the surface (underground), as well as the quality and the thickness of the existing plaster layer.
Depending on the material and thickness of the wall, the following insulation thickness are recommended to be observed (for apartments or offices):
Material of the wall ISOMASTER® EPS 80 Insulation thickness U value (W/m2K) achieved with the THERMOMASTER® system Improvement of the insulation ability of the structure, achieved the THERMOMASTER® system
Small-sized solid brick (25cm) 8 cm 0.39 79%
Small-sized solid brick (38cm) 8 cm 0.38 74%
Reinforced-concrete wall, (20cm)9 cm 0.38 87%
Panel building 6 cm 0.37 58%
Hollow brick (B30 - 30cm) 8 cm 0.37 75%
Modern hollow brick (30cm) 7* cm 0.29 60%
Porous concrete (30cm) 4* cm 0.31 53%
*in case of walls mentioned above, application of the thicker insulation than required is necessary in considerations of risk of vapour condensation. In bathrooms and wet spaces the internal surface of the walls must be tiled up to the ceiling, and only silicone finishing coat can be applied outside (for more details see: THERMOMASTER® Instruction Guidline).
Recommendations for the application of the system:
The wall must be free of loose plasters, particles and paints, if necessary, the surface unevenness can be repaired by cement plaster. In case of strongly absorbing wall (e.g. porenbeton), it is recommended to use MASTERFIX® PRIMER).
First step is the fixing of the socle profile by hammer fixed expansion plug (4pcs/m), minimum 30cm above the level of ground or pavement. The unevenness of the wall can be equalised with levelling pieces, the lengthening of the socle profile is with profile connector .
The temperature of air must be over (+)5ºC during the adhesion of ISOMASTER EPS boards. The adhesive material could happen with MASTERFIX® PRO or FALFIX Plus. The dry material is mixed with water as specified on the packaging and mixed again after 2–3 minutes of rest. The mixed adhesive should be used within 20–30 minutes depending on the ambient temperature, but dilution of it after mixing is not allowed. The adhesive should be applied alongside, around as well as in 2-3 spots on the surface of the insulting sheets, (do not apply the bonding material onto the edges of the board). The bonded surface is min 30% of the tight-jointed ISOMASTER® EPS board, the thickness of the adhesive should be 0,5–2,0 cm.
After setting of the adhesive (minimum 1-2 days, depending on the temperature), the following step is the eliminating of the surface unevenness and anchoring. If the height of the façade is less than 8m, anchoring is only necessary, when the bonded surface were critical (e.g. plastered, painted, strongly absorbing). Over 8 meter building height, supplementary anchoring is always important, 4–8–12 pcs/m² is recommended, depending on the type of anchor, material of the wall and the building height (for more details see: THERMOMASTER® Instruction Guidline). The respective anchoring depths must be always observed, and kept (e.g. in consideration of the thickness of existing plastering).
The application of the corner profiles happens before applying of the base coat and fiberglass mesh. This working process is sensitive to weather conditions, the ideal ambient and surface temperature is (+)5 – (+)25°C. During the setting of the base coat (depending on weather but minimum 1-3 days), the temperature is not allowed to sink under (+)5°C, in case of too warm (over (+)25°C) or windy weather, supplementary precautions must be made. For base coating MASTERFIX® PRO or FALFIX Plus are also applicable. The adequately mixed material must be used within 20-30 minutes. The material (~3 kg/m² in the first layer) is applied onto the ISOMASTER® EPS surface by a notched trowel, then the fiberglass mesh must be embedded with 10 cm overlapping. The second layer of base coat requires only ~1,5kg/m2 material.
A thin key coat (CORATREND Primer or Coramix Primer) is necessary after setting of the base coat, which is intended to act as a preparation for the application of the finishing coat. Before applying the finishing coat, the primer must be completely dried. The top coat (Coratrend or Coramix) can be made of acrylic or silicon dispersion. A considerable advantage of silicone dispersion, that its vapour transmission and water-repellent ability is better. Floated and ribbed structure with particle size of 1,5mm and 2mm can be chosen. When choosing the colour of the finishing coat, it mustb considered, that the same colour of look differently on big surface than on the colour patterns.
Before the colouring works, the following tasks must be performed:
•on a façade, only material made of the same production charge (indicated on label) can be used, otherwise the materials derived from different charges must be mixed.
•the plaster deposited on the cover of the bucket must be scraped back into the bucket.
•CORATREND® render can be diluted with maximum 0,5-2,5 dl of water / bucket, depending on the weather conditions, the amount of added pigment and the absorption capacity of the base coat. For every bucket the same quantity of water must be added, then mixed evenly, but the dilution extends the setting time on the wall, especially when the vapour content of the air is high.
Applying of CORATREND® top coat is also very sensitive to weather, warm and windy weather is not suitable for high quality work. The optimal temperature is about (+)15 - (+)25°C. Between (+)25 - (+)30°C, colouring could happen only on shaded surface. Cold weather (below 10°C) and the high vapour content (over 75%) is not proper. Fresh top coat should be protected from wind, intensive UV radiation freezing and rain.
For the insulation of the socle part of the building, XPS thermal insulation can be used, the bonding and coating happens on similar way, but the finishing layer is CORAMIX marble plaster.
