I am currently re-caulking around my windows and doors. Around the perimeter of some windows the mortar line from the brick is flush with the window frame. Is a bead of caulk needed along (on top)of this grout line, or only where there is void space between the window and mortar? I know that the grout is porous, but I am unsure if it would enough allow moisture to penetrate and cause damage.
Your best bet is to run a continuous bead all around. This will seal the exterior trim of the window to the brick and even everything out. In some places you may need to use a lot of caulk, in others just a thin line. Most important on the top as a non-continuous run of caulk would add several edges that could become potential leaks.
Thanks for your response. I hadn't even considered the fact that the bead wouldn't be continous if I only sealed the gaps. thanks again.
