Solid, unpainted stucco shouldn’t suffer damage from dots of glue used for this task. If the stucco is dirty, you may notice slight marks when you heat and peel the glue away, but these aren’t permanent.

However, not all stucco walls are solid stucco. Some are “faux” stucco with a foam backing. This kind of stucco veneer is more susceptible to damage, including damage from hot glue. We don’t suggest attaching anything to these kinds of stucco walls, so make sure you check the stucco type before starting this project.

The best tape that works on stucco is the kind made explicitly for stucco surfaces. Look for tape that specifies stucco, masonry, or cement installations. The adhesive usually needs to be thicker and more durable to remain stuck to these rough surfaces.

You can use small bits that are up to 3/8 inch in diameter, or larger bits that are 1/2 inch or more in diameter. Make sure the bits you use are coated with carbide or diamond; this information is usually visible on the package. You can also use hole saw bits to drill into stucco.

Cracks in the chimney can be very serious, depending on their location and size. Even small cracks can become serious over time if left unrepaired. Cracks allow heat and moisture to deteriorate your chimney and harmful carbon monoxide gas to seep into your home. Small cracks can often be caulked, while large cracked sections may require full replacement.
