Some older brick material is extremely hard, making it tough to create a hole. Rather than using a typical wood drill bit, always use a masonry drill bit when drilling into brick. For extremely hard brick, using a power drill with a hammer function may give you better results. The drill bit will heat up as it goes into the extremely hard brick, so you may need to stop after a few minutes and allow the bit to cool before starting to drill again.

Discoloration ondifferent types of brick can range from harmless to red flag. For example, efflorescence that is caused by a buildup of water-soluble white salt is considered harmless. However, green or greenish-yellow stains are caused by salts that are harmful to brick. Staining can also be caused by rust, corrosion, lime run, soot, algae, or moss.

Yes, you can paint stone on the exterior of a house. It’s important to properly prep the stone by cleaning off dirt and debris. You’ll want to apply at least two coats of paint to get the most even and complete coverage. Any pinholes or missed spots, however small, can allow moisture to get into the masonry and potentially cause the paint to blister and peel from the stone.

Cutting stone comes with a number of safety hazards. First and foremost, if you’re not comfortable with the equipment required to cut stone, including blades and grinders, you could easily injure yourself. The heavy machinery also poses a risk to your ears if you don’t wear proper ear protection; similarly, you need to wear eye protection to keep debris from irritating your eyes.

However, the biggest risk from cutting stone comes from the stone dust. When breathed in, stone dust can be a huge hazard to your lungs. Always wear a face mask when cutting stone to prevent inhaling stone dust, and thoroughly clean the work area when you are finished.

To avoid injury, we recommend hiring a stone-cutting professional, rather than attempting this job yourself.
