Product Usage


  • For sealing joints and connecting joints in glass and window construction, in metal construction and porous substrates (eg. concrete, plasterboard and brick)
  • Silicone must not be used in aquarium construction, on marble/natural stone, in underwater applications, as mirror adhesive and in areas with direct food contact
  • Not suited for plastics with in general poor adhesion to silicones (eg PE, PP, PET)



Application


Substrate Pretreatment

  • The substrate must be dry, firm, and free of dust and grease (clean with isopropanol, if necessary)
  • Porous substrates (e.g. concrete, plasterboard and untreated wood) must be primed
  • Before primer application, remove any cement slurry, mold release agents or impregnations
  • In renovation projects, old sealant, remains of paint and loose material must be fully removed
  • On coated substrates (paints, lacquers), compatibility to the sealant must be tested
  • The joint must always be provided with a suitable, correctly dimensioned joint backing (e.g. PE cord, rock wool) to prevent adhesion on three faces
  • To avoid contamination and to achieve a precise joint, we recommend masking the joint edges with adhesive tape before primer application and filling

Tool Application

  • After applying the sealant with a suitable manual, battery-powered or pneumatic caulking gun, the sealant can be smoothed in the joint with water or with a neutral, non-staining water-based smoothing agent and a suitable tool (e.g. jointing trowel)
  • Smoothing is not only recommended for optical reasons, but also establishes close contact and good adhesion to the substrate
  • Remove excess smoothing agent (risk of schlieren)
  • Any adhesive tape used should be removed immediately after smoothing
