I have bricked up a window to be able to install a garage door in a house made of leca. The frame for the door will be attached through the leca, both through the old and the new that I have bricked up in the old window.
I have used mortar B and 19x19x59 blocks. The joints are about 1 cm.
How long does the mortar need to cure, or rather, when can I start drilling and working the new section without having to worry that it hasn't cured properly?
Best regards,
Lenny
