How do you cover block pillars with concrete?

To cover block pillars with concrete, first ensure the surface of the blocks is clean and free of debris. Then, mix the concrete according to the manufacturer's instructions and apply it to the pillars using a trowel or concrete float, ensuring an even coverage. For better adhesion, you can use a bonding agent on the block surface before applying the concrete. Finally, smooth the surface as desired and allow it to cure according to the concrete specifications.
