Hi
I have fixed some terracotta tiles around the outside of my pond, using suitable external floor and wall adhesive but now have the problem of grouting them !
I had this vague idea of colouring the recommended and sizeable bag of grout - white is out of the question - but can't see any suitable colourant. Is such a dye available ?
The alternative is to resort to sand and cement. Has anyone any recommendation on the best mix or method to ensure longevity.
TIA Andy
