Hi @Wally47,

Sikaflex 11FC comes in grey, black and white. They all perform the same for filling over the top of your expansion foam. The choice of colour is up to you and the situation in which you're using it. For instance, if you are filling a gap in concrete, then grey would typically be the best choice.

Please let me know if you have any questions.
