Do the joints need to be cleaned out after brick grinding is completed?
That’s a big Yes! It is very important to remove any dust or lingering debris in the brick joints. Dust will prevent the mortar from properly bonding to the brick surface. Dust is a film that absorbs the moisture in the mortar joint and doesn’t allow the existing joint in the brick to absorb the moisture. Thus the pulling of moisture from one mortar joint to another can’t take place with the dust in its way. So make sure you see the mason cleaning out the joints after grinding. Are there different types of brick joints? Like in stone pointing, make sure you go over what type of joint should be going back in the brick joint. There is a tool for all types of joints make sure they know you’re aware of this.
