Morning, first post here so go easy.
I laid some Indian Black Limestone flags as a small 3x3 patio at the weekend. I then mortated between the flags, but I dyed the mortar a dark grey to better match the slabs. However, there seems to have been some dye transfer along the mortar lines meaning I now have darker tracks along where the flags meet. There was no warning of transfer on the packaging (Bostik cement dye) and it said it was suitable for colouring mortars. What are my options? It's now dry. I'm thinking I should have sealed the flags before mortaring (hind sight and all). The flags aren't actually as dark as I'd like, so I'd not be adverse to dying them all to match the lines, but whats going to happen in a few years (it is a lightly trafficked area). Will sealing them darken them at all?
