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
