Excellent compatibility with natural stone


With conventional sealants, discolourations around the edges frequently occur due to silicone oils. Thanks to a special recipe, natural stone sealant is the only sealing compound to prevent these kinds of discolourations.



Outstanding suitability for high stresses outdoors


Very high resistance to ageing, weathering and UV




Permanently elastic

NoticeThe colour display is for guidance only. For an exact colour selection, please use our colour sample cards.


Special information on suitability for insulating glass:


Natural stone sealant should only be used in conjunction with primary sealing. When using treated glass, compatibility must be checked in advance. Excellent adhesive properties on most glass used in the production of insulation glass, e.g. sheet glass, laminated and treated glass, aluminium spacers etc.



Complies with building material class B2 in accordance with DIN 4102.


Due to the large number of varnish and glazing formulations available, especially on alkyd resin paints and powder-coated aluminium, always carry out your own tests on the area first. Remove excess smoothing agent from the surfaces. Risk of yellowing on contact with white alkyd resin paints cannot be excluded. The transparent colour is adjusted to be milky/cloudy. Does not cause soiling around the edges of natural stone. (Migration of the softener from the sealant into the natural stone. If the surface is soiled, it may not be possible to completely remove the sealant and it may result in discolouration of the surface.) Natural stone sealant is not suitable for adhesive bonding or filling cavities.


For materials and substances that come into contact with the sealant after processing, the user must ensure that their content or fumes cannot cause any impairment or alteration (e.g. discolouration) of the sealant joint. 5995000403To determine the precise colour, use sample card art. no.
