Sikaflex-512 Caravan is only marketed in white colour, while Sikaflex-252 is available in black or white. As Maggyd’s husband advises Sikaflex-512 Caravan is described by SIKA primarily as a ‘weather resistant sealant’ (though it will certainly bond well too), whereas Sikaflex-252 is marketed as an ‘assembly adhesive’. So I guess you ought really to use the latter for fixing a roof-mounted solar panel.


GOOGLE-ing on “motorhome solar panel adhesive” suggests that Soudaseal RV61




would be a viable alternative.

The Screwfix-marketed SIKA product you’ve mentioned is “Sikaflex EBT” and was discussed here:
