ISO-TOP FACADE SEAL is an almost odourless gun applied hybrid polymer sealant. Its colour fastness and high resistance to both weather and UV light make it ideal for sealing external building movement joints.

ISO-TOP FACADE SEAL bonds without primer even on moist surfaces, cures blister-free and is very good to paint over as per DIN 52452.

  • can be processed from 0 °C
  • permanently flexible after curing
  • complies with ISO 11600 F-25LM (maximum total deformation 25 %)
  • for versatile use on many standard construction surfaces
  • can be painted over well (with water-based paints)
  • also bonds to slightly moist surfaces
  • free of solvents, isocyanate and silicone
  • non-corrosive
  • leaves no stains on porous surfaces such as natural stone, dressed stone, marble and granite
  • complies with ISO 11600 F-25LM
  • complies with EnEV requirements and the recommendations of the RAL “installation guide”


  • sealing of indoor and outdoor joints during renovation and new building work as per DIN 4108-7
  • usual moving joints in buildings as per DIN 18540
  • sealing between window and door frames and masonry
  • expansion joints between construction materials
  • sealing of solid construction joints on the exterior
  • connection joints for roof and facade



12 tubular bags (e 600 ml) per box.

Good: water, aliphatic solvents, diluted inorganic acids and alkalis, oils and greases.

Poor: aromatic solvents, concentrated acids and chlorinated Hydrocarbons.

* The specifications refer to the completely cured product. Measured according to standard climate DIN EN ISO 291 at 23 °C / 50 % RH. These values may vary depending on environmental factors such as temperature, moisture and type of substrates.


Can be used on all standard construction surfaces such as concrete, aerated concrete, rigid PVC, timber, metals, fiber glass plastic (except for polypropylen, polyethylen, polytetrafluorethylen and silicones). Porous surfaces in water loaded applicatios should be primed. We recommed a preliminary adhesion test on every surface. The recommended joint dimensions and maximum permissible total movement must always be heeded. Permanent pressure on the joint must be avoided as this can otherwise lead to stains or bonding problems. In the case of construction sealing foils (e. g. Soft PVC, butyl rubber, APTK, EPDM) there may be incompatibilities in the form of discolouring or loss of adhesion. The adhesive surfaces must have a sufficient load-bearing capacity and be clean, dust- and grease-free. 

Dry surfaces are particularly suitable. The best adhesive values are achieved here. ISO-TOP FACADE SEAL also bonds to moist surfaces and even under water. Curing is effected by air humidity at room temperature and takes place from outside to inside, slowing as time progresses. At low temperature and / or low humidity, the curing process is slowed significantly.
