How much coverage is recommended when applying mortar to masonry block?

When applying mortar to masonry block, it is recommended to use full coverage to ensure a strong bond and structural integrity. Full coverage means that the mortar completely fills the space between the blocks, which helps to create a solid connection and prevents the infiltration of water and air. This is crucial in masonry construction, as it contributes to the durability and longevity of the wall or structure being built. Adequate coverage helps to eliminate voids, which could otherwise lead to weakness or failure of the masonry assembly. Thus, ensuring full coverage is vital for achieving optimal performance of the masonry system.
