KOMBI RAPID – EPS board adhesive
External thermal insulation composite system (ETICS) and bonding EPS or XPS boards to mineral (e.g. concrete, ceramics). To be used in KABE THERM RENO, KABE THERM SM and KABE THERM SM RENO, KABE THERM ELASTO, KABE THERM AVANT, KABE THERM MARMURIT/MOZAIKER, KABE THERM MARMURIT COLORATO/MOZAIKER COLORATO and KABE THERM CK EWI systems, where thermal insulation boards are simultaneously mechanically fixed to the substrate ( acc. to technical project). Thermal insulation of foundations, walls and basements (installing EPS boards, EPS boards to mineral and bitumen substrates). Filling joints between EPS boards, gaps resulting from cutting boards. Vertical expansion joints in walls. Sealing joints, e.g. at window sills, window sill tiles, balcony tiles, cellar or basement windows.

• High thermal conductivity (λ=0.0348 W/m*K), no risk of thermal bridges
• Low volume increase and high dimensional stability
• High adhesion and impact resistance
• Quick setting time
• Easy to apply and process
SUBSTRATE PREPARATION: Apply to a sound substrate (no cracks or crevices), clean, degreased, free from dust and even. Allowable wall deviation should not exceed -4 mm and +2 mm (take the measure with a straightedge 2 m long
at an accuracy of 1 mm). In case of higher deviations apply a levelling coat. Clean mechanically foundations and walls removing dirt, algae and fungi, then wash with water and disinfect with ALGIZID preparation. The substrate must be
protected against capillary action, moisture intake and precipitation. Pay special attention to avoid hoarfrost on glued surfaces. Insulation boards (other than cut) can contain anti-adhesion agents. Perform an adhesion test. If necessary, grind the back side of the boards. To enhance adhesion, accelerate hardening and improve structure, the substrate should be moistened with water by using a sprayer.
ADHESIVE PREPARATION: Directly prior to using the adhesive, stir it thoroughly. Screw it on the gun. Dispose the initial portion of adhesive (about 30 cm) until pressure in the gun is eequalised, direct it to the side (not to be used). Start fixing the boards always from the bottom, supporting the bottom row on the start stripe or foundation heel. Remove any dirt with special cleaning wipes or PU foam cleaner. Note: The cleaner can react with the EPS board resulting in its damage. Hardened adhesive can be removed only by mechanical means. Places where the adhesive is exposed to UV radiation should be protected within 10 days from adhesive application. Use silicone or acrylic render to protect against UV radiation.
BONDING BOARDS WHILE PERFORMING EXTERNAL WALL INSULATIONS: Apply the adhesive on boards along their circumference at a distance 2 cm from the board edge and with a band shaped in letter “M” or “W”. Within maximum 10 minutes from adhesive application, put the boards on the substrate and press by using a straightedge. Boards’ position can be corrected within 10 minutes from bonding. Mechanical fixing by installing pins can be started 3 hours from gluing. The adhesive joint obtains full mechanical strength after 24 hours from gluing. Note: Setting time may be longer at lower temperatures and low air humidity.
BONDING BOARDS WHILE PERFORMING THERMAL INSULATION OF FOUNDATIONS, CELLAR WALLS AND OTHER UNDERGROUND BUILDING SECTIONS: Apply the adhesive on one side onto the substrate in vertical stripes
spaced 20÷30 cm apart. In case of boards 150÷160 cm wide, apply at least 5 stripes. Put the boards on the substrate after about 10 minutes from applying adhesive and press firmly. Fill the remaining gaps and joints between boards with adhesive.
USEFUL HINTS: While performing thermal insulation of underground building sections, the adhesive can be used only in the so-called light damp proofing systems – perform an adhesion test. Do not use it in the case of permanent
exposure to water e.g. submerging caused by high level of ground water level – heavy damp proofing or waterproofing systems. Do not use to glue PE, PP, PTFE, silicone surfaces, covered with anti-friction, lubricating agents (membranes with PE film). Do not use in substrates waterproofed with bitumen solvent-based products – there is a risk of damage to the boards (read and understand thoroughly the product manual and check if the manufacturer allows for gluing EPS boards). Boards can be glued once the waterproofing coats are fully dried – refer to the product manual. Do not use during precipitation, strong wind or when exposed to strong sunlight.
* open time and comsumption depend to great extend on ambient temperature, air and substrate humidity, container temperature, application method, layer cross-section, substrate wetting etc.
** hardening time depends on weather conditions.
