How to Drill into Stucco-The versatile and Unique Guide

A property’s value and visual appeal can be increased by making exterior improvements. However, it is important to exercise caution while having work done on the exterior of a property if stucco is present. It’s not wise to drill into a stucco wall without first taking the necessary safety measures. Today, we’ll discuss several considerations before deciding how to drill into the stucco.

Stucco is a plaster used to cover interior surfaces like walls and ceilings. It may be drilled into and used both inside and outside. But you must plan, check that you have everything you need, and not go overboard with several fastenings or attempt to hang excessively from this covering. This decorative coating is simple to fix means that any faults or unwelcome holes can be patched, and the wall may be returned to its original, attractive state.

What is Stucco

The substance stucco is used in buildings. It consists of water, a binding agent, and an aggregate (often sand). It’s usually used as a decorative coating and applied while still wet to walls and ceilings before being allowed to dry. Interior and exterior siding, as well as a decorative architectural finish, are also possible applications.

After it dries and is applied to walls and ceilings, it has a texture similar to that of concrete, which is likely why individuals are hesitant to drill into it: they think that, like a concrete finish, it would crumble and collapse to dust if a hole is drilled into it. However, drilling through Stucco is not impossible and may be done for various reasons.

Is It Possible to Drill Through Stucco?

With the correct drill bit and equipment, stucco can be drilled through. For drilling into stucco, masonry bits with carbide or diamond tips are the way to go, and a hammer drill comes in handy for making deeper holes.

You can use a regular drill for smaller bits, but a hammer drill is much more convenient.

What Type Of Drill Can Use

For the tiny parts up to about 3/8 in., such as those included in a set, “The use of a regular drill is entirely acceptable. If you simply need to drill a couple of holes, this will be enough for these basic bit types.

It is possible to do these without a hammer drill, but doing so would be much more time-consuming and difficult than with one. To make a hole larger than 3/8 inches, you’ll need a hammer drill or rotary hammer “to accommodate the hole’s increased demand for space.

I would not suggest using a regular drill with a larger bit to drill into the hard stucco surface.

There is a wide variety of drill bits available, but a carbide or diamond-coated bit is what you should choose. Check out Home Depot’s online selection to get a feel for your options.

Smaller Bits:

The smaller pieces are probably the most widespread and simple to obtain and implement. I think these are 3/8-inch bits “less than or equal to a certain diameter.

Larger Bits:

Remember that 1/2 is a very significant number “bit sizes and up may need a specialised SDS connection as they were designed for rotary hammers and not standard drills.

Your drill driver can use SDS-type bits, which can be adapted.

Hole Saw Bits:

Finding hole saw bits with either a diamond or carbide tip is also possible.

When used properly and with patience and persistence, a hammer drill can do almost anything. If you’re making multiple holes with the same bit, adding water to the mix will help keep it cool.

Before Drilling Must Check These Things 

How well did the stucco get put in

Drilling into stucco without verifying that it was placed correctly is a recipe for disaster. In addition, drilling through the stucco may worsen water problems if not placed correctly. 

Water may seep through holes in the stucco, and if there aren’t any channels for it to drain away, that can lead to mould and mildew. Rot, decay, discoloration, and degradation result from mould and mildew growth.

Are We Talking About the Proper Stucco Here

To your surprise, not all stucco can be drilled. Drilling into the external walls of your home requires the proper sort of stucco to be put. Stucco constructed from cement won’t be porous like some other types. Simply knocking on the wall will provide the answer. It’ll be rock-like in consistency. Knock softly; you don’t want to hurt your hand.

 Cement stucco may be safely drilled through. In the absence of hardness and the presence of a hollow sound, EIFS stucco is a strong candidate for the exterior finish of your home. However, if the stucco is EIFS, you should contact the manufacturer to learn how to drill through it without voiding the guarantee.

Will There Be No Obstacles Hereafter

Inspecting the surrounding region is the final step before drilling into a stucco home. Keep an eye out for electrical wire behind walls to avoid starting a fire or getting shocked if you accidentally drill into it. It’s also important not to go further down than required while drilling. 

Were you to dig too deeply? You may crack the walls of the house. Make sure there is no additional space for water to pool up by using the correct size screws for the task.

What Tool You Need For Drilling Stucco

To successfully drill through stucco, you won’t need a lot of tools. However, the necessary tools are detailed below.

  • A drill, either cordless or attached to a cable,
  • Cement drill bit
  • Tools for measuring and drawing
  • Sticky Tape

Make pencil marks over the drill holes.

As a first step, use a pencil to outline where each drill hole will go. Always double-check that your markings are legible and in the right spots.

Examine the pencil marking spacing using a ruler to make sure it makes sense. To avoid cracking the stucco surrounding the hole, you can minimise damage by taping off the area and drilling into PVC tape. This additional glue will make the hole more sturdy and complete.

Find out what to anticipate.

Checking the wall type before beginning drilling is a good idea.Always indicate the locations of the weep screed and the vertical and longitudinal control joints before drilling into a wall of category 2 type.

If you are drilling into a level 1 wall, this shouldn’t be too much of a problem.

Put your masonry bit in the chuck and drill a few pilot holes.

Attach the masonry bit to the drill’s chuck. As stucco hardens the same way as concrete, we need to use a masonry bit to drill through it without cracking the surrounding material.

Once the masonry bit is securely connected, you may begin drilling by first making small pilot holes with the drill bit at each spot marked with a pencil.

If you do this, you won’t have to worry about slipping when you make your first hole in the stucco.

Go through the motions.

You can easily drill through stucco if you hold the drill parallel to the wall and steadily press down on it while squeezing the trigger. Employing the hammer setting on your drill will allow you to generate the highest torque.

Do not be frightened if you run across aluminium nails or stucco netting; just keep drilling at a consistent torque and speed until you reach the desired depth.

Bring the drill out while it’s still turning.

When the hole has been drilled through, keep the drill spinning before taking out the masonry bit. This will prevent surface cracking and guarantee a consistent drill hole.

How to Screw Into Stucco

Screw Into Stucco

To drill holes in stucco and insert fasteners, you will need stucco screws, a power drill or impact driver, and a carbide drill bit. You can find a corresponding drill bit in most stucco screw sets.

Starting with a pilot hole drilled through the plaster is the first step. An electric drill is then used to drive in the screw..

For longer-lasting attachments, try using a stucco anchor and screw. Therefore, its load-bearing capacity improves. However, the anchor must be pounded into the drill hole to pilot.

Before beginning the task, put on protective gear, including goggles, a face mask, and nonslip shoes. You will have access to a power tool, such as a drill or an impact driver. So be careful to take the correct safety procedures while handling power equipment.

Put a mark in the desired screw location.

Start by determining the precise location of the screw and making a mark.

Use a pencil to mark the stucco to keep the stucco clean and free of smudges and scratches. Using a pencil is better since it may be erased to restore a neat appearance afterwards.

Perform a drill pilot hole.

The next step is to swap out the existing drill bit in the impact drill for one made of carbide. Then, centre the drill above the initial mark.

Stucco screw kits typically come with a masonry drill bit as well. So pick a drill bit from your masonry drill bit set that’s just a hair smaller in diameter than the screw.

Keep the drill perpendicular to the plaster wall at a right angle. The resulting wall hole will be perfectly straight.

Create a little opening in the wall at the indicated location.. Making a straight, even hole is the best way to do this slowly and steadily. Stucco walls are less likely to chip if you drill slowly. But first, let’s get the pilot hole cleaned up..

Fill the gap with caulk if you like

This is discretionary. Silicone caulk can be added within the hole to prevent further damage to the wall while drilling.

Insert a screw anchor into the hole if desired.

Stucco is a sturdy material, and stucco screws have their own special threads, so you won’t need to drill a pilot hole before you install them..

For more demanding tasks, you can skip this step. Instead, the anchor strengthens the grip. Then, stucco screws and anchors are pre-cut to fit the appropriate sized plastic anchors.

The anchor must be pounded into the wall with the hammer. Anchors can be inserted using a screwdriver if desired.. Do that until the anchor reaches entirely inside of the wall.

Anchor the stucco with a screw.

Stucco screws and concrete screws are the specialised fasteners you’ll be employing. This is because, like concrete, stucco is an extremely durable substance.

These screws are designed with a diamond head to improve their ability to drill through tough materials like stucco and concrete. In addition, stronger fastening is ensured by the deep threads.

To prevent rust and corrosion, certain screws have a blue coating. If you don’t want to cover the blue screws with paint, go with the more subtle natural hue.

Do you need an anchor when drilling into stucco?

Stucco is thick and stucco screws have unique threads, thus a pilot hole is unnecessary.. For more demanding tasks, you can skip this step. Anchors improve gripping ability.

How do you drill into concrete stucco?

The wall mark must be aligned with the drill bit, which must be pressed firmly against the wall with the help of some serious back pressure. With a well-timed trigger pull, you could easily bore through the stucco. Keep continuing until you reach the desired depth, then switch to the reversing gear and remove the drill bit.


Simple methods exist for drilling through the stucco. A bit of forethought and calm waiting is all that’s needed.

Any issues that may arise can be avoided if you understand what to look for. You’ll be well-prepared for everything you may encounter when you bore through the wall, both in terms of the wall’s composition and the materials it’s made of.

This was a wonderful experience, so I hope it’s useful!
