Yes, it is normal to see some minor hairline cracks in brick or mortar over time, often due to natural foundation settling. However, not all cracks are harmless. You should be concerned and contact a masonry professional for an inspection if you notice cracks that are getting wider or longer, or if new ones keep appearing. Other serious warning signs that can indicate significant structural or foundation damage include large vertical cracks (especially those that widen as they go up), stair-step cracks, L-shaped cracks, and deep horizontal cracks. Factors like temperature changes, moisture, and structural loading can also cause cracks to form or worsen.

No, you shouldn’t lay bricks directly on dirt. While it might seem like a shortcut, it leads to a patio that shifts, sinks, and becomes a maintenance headache. Dirt expands, contracts, and erodes—none of which mix well with long-term stability. To build something that lasts, excavate the topsoil, compact a layer of crushed gravel, and add a coarse sand-setting bed. This layered base gives your bricks proper support, allows drainage, and helps block weeds from creeping through. Cutting corners here just means you’ll spend more time—and money—repairing your brick patio later.

When painting brick, each application method has distinct advantages and disadvantages. Spraying is significantly faster but may not penetrate deeply beyond the surface layer. Rolling is effective for working paint into the brick's texture but can be less effective on mortar joints. If you opt for a roller, choose a thick nap of at least a half-inch to ensure paint gets into all the crevices for even coverage. Using a brush is generally not recommended as it is very time-consuming and provides poor surface penetration. Ultimately, a combination of spraying followed by back-rolling is often the best strategy for a durable and even finish.

You may not need a hammer drill if you’re planning on drilling one or two very small diameter holes in brick. For holes with a diameter of 3/16-inch or less, a regular drill with a masonry bit can do the job. However, the bit will heat up quickly, and the process will take significantly longer than with a hammer drill. Prepare to cool your drill bit down in a bucket of water more often.
