Should You Drill into Brick or Mortar – The Ultimate Guide with Authentic Technique

When drilling into a brick wall, many individuals don’t stop to ask themselves, “Which portion should you drill in mortar or brick?” until it’s almost too late. So what’s better, drilling into the brick or the mortar?

Brick is ideal for drilling into as long as it is in excellent shape. It’s more robust than masonry and can support heavy items like televisions. However, the mortar should be drilled if the brick is too weak and easily cracked. Mortar, alas, can never provide a reliable grip for anything heavier than a feather.

On the other hand! What about breaking the walls down? There is a problem, and you’ve identified it correctly. Let’s take a closer look,

Should You Drill in Mortar or Brick

Navigating through brick or mortar is complicated and depends on various criteria. Knowing how the two materials respond to drilling differently is crucial. Bricks make walls and other masonry structures, and mortar keeps them together.

There are several variables to consider when deciding whether to drill into brick or mortar, including the kind of brick, the diameter, and depth of the planned hole, the age of the brick, the type of anchor, and the weight being fastened. Typically, brick is sturdy and can withstand more weight than mortar can. On the other hand, aged and brittle brick may not be up to the task of supporting deep excavations, huge loads, or expansion-style anchors.

Additional work, such as drilling larger holes or using expansion anchors, might compromise a brick’s structural integrity. Excessive circumferential tension brought on by the anchors might cause the material to break. Drilling into the mortar is preferable if the brick displays symptoms of aging, such as spalling or defects. Finding a filler that will blend in with your brick’s natural color is also challenging.

The softer nature of mortar makes it easier to drill through and more manageable to fix or repair. Screw expansion plugs and other types of fasteners won’t work in mortar because the force of the anchor will press on the unharmed bricks. However, heavier things are too heavy for artillery to support.

Each choice has advantages and disadvantages that you’ll want to weigh carefully. Check the mortar and bricks to see whether they are in good enough shape to drill. Is it a big, hefty thing or a light, the little one that you plan to hang? Does the brick have a solid foundation, or would mortar be a better choice? Are these holes you’re digging shallow or deep?

Which Drill Should Use?

Can a standard drill bit be used to bore through concrete, brick, or mortar? A hammer drill or rotary hammer is your best bet if you need to drill into brick or mortar. First, the drill bit is turned and hammered into the material simultaneously. Then, by pulsating the bit back and forth, the drill bit’s tip is pounded into the material being drilled. Finally, by applying pressure, clean holes may be punched through the brick or mortar, and anchors can be set.

You’ll need a masonry bit if you want to drill into brick or mortar with your hammer drill. As a result of the drilling process, the flutes of these bits are typically wider.

How to Prevent Damage When Drilling Into Brick or Mortar

Naturally, there are other considerations before beginning drilling. Even if you have all the gear you need, there are still some things to think about before you begin drilling.

Identifying the Brick’s Origin and History

The dimensions of the hole, both in-depth and breadth

What kind of anchor is being used? How much force is being exerted on the bolts?

Before settling on a method for drilling holes, it’s essential to weigh all of the options available to you.

Drilling Bricks

More strength is required in the holding material; the heavier the thing. Brick is typically preferred over mortar due to its durability and stability. Thanks to its sturdy construction, brick can support a lot of weight. Since the mortar and bricks around it will also help the brick, it may be used to anchor big things securely.

Drilling Bricks

However, there are a few drawbacks to brick, the first being the challenge of color-matching when filling the holes left by the drill. If the color of the patches is less of a concern, this may not be a problem. Alternatively, you might paint over the brick if it has been painted afterward.

If the brick is ancient and brittle or crumbly, however, you might choose to use the mortar instead, presuming it is in excellent condition. This is because brick that has been damaged or aged has lost its strength and may break if drilled with masonry.

Drilling for Mortar

Since mortar is softer than brick, it can be drilled more easily. In addition, based on the holes’ size and the item you wish to attach, mortar may be preferred since it is easier to repair than brick.

However, as mortar is somewhat soft, it is not the ideal choice for anchoring heavy or massive, unwieldy things.

Quantity and Spot

The next thing to think about is where you want to drill the holes in the object. It is important to take measurements before drilling into a wall to ensure you get the exact depth you require.. It needs to be either just where you want it or close by. A garden hose reel, for instance, should be hung from the exterior brick wall of a home at a height that allows you and your household members easy access but is yet low enough to the ground that unreeling the hose is a breeze.

Always use a stud or a sturdy block when installing oversized items like flat-screen televisions.

Following that, hole size is crucial. They should be big enough to serve as anchors but not so big that the object shifts or moves around when installed. When planning, it’s also essential to think about the anchors you’ll be using.

Definitions of Different Anchors

Anchors come in several forms and some are built solely for use with concrete, expanding the range of possible applications for brick installation. As an example, masonry materials often employ Tapcons, an abbreviation for masonry concrete screws, to anchor them.

Tapcons stand out against backgrounds because of their vivid blue hue. They can be either with a flathead or a Philips head and otherwise appear the same as standard screws.A proper instrument can turn the hexagonal head of each one. It is possible to drill the hole and insert the screw. The screw’s length should be suitable for the job at hand. Here are some other options for masonry anchors to consider using.

Bricks are less likely to break when using double expansion shield anchors.

Lightweight items are ideal for use with sleeve anchors.

Most brick-and-mortar projects will employ them as their anchor of choice. Therefore, ensure you have all the necessary drill bits before beginning.

Brick-Drilling Equipment

Drilling Hammer

When working with masonry materials like brick, concrete, or stone, the hammer drill is your best choice. A hammer drill produces a chipping motion by repeatedly pounding the bit at high speed as the drill is spun.Hammer drills may produce up to 50,000 blows per minute when they contact the work area (BPM).

If you need to make several holes in brick, renting or buying a hammer drill is probably worth renting. Hammer drills may cost anywhere from $200 to $500, depending on the type.

Simply use the tool’s turning capabilities by disabling the hammer. The size and weight of hammer drills make them impractical for the primary rotary drill.

Drilling Device Featuring a Rotating Hammer

You can also use a hammer drill driver, or a rotary drill with a hammer motion, to bore holes in brick.

Rotary drilling is the primary purpose of these drills. They switch to hammer drilling mode with a turn of the plastic clutch collar. Rotary drills with this capability can reach speeds of up to 34,000 BPM.

A Masonic Drill Bit

The spaded end of the carbide masonry bit is perfect for chipping away at the brick. The flutes and grooves inside deflect any debris that may otherwise enter. If you anticipate needing a lot of masonry bits, you may purchase complete sets. It is possible to purchase masonry stones independently, notwithstanding their astronomical cost.

The Best Anchor for Your Walls

A lag shield is a way to go if you need to hang something heavy from a brick wall.The brick’s hole is first set with the anchor, then the screw is force up into it. Once you turn the screw, the zinc-alloy anchor expands and secures the object firmly.

To properly install an anchor, use a drill bit that is a full size more significant than the anchor.

Mechanic’s Vacuum

A shop vacuum has two purposes: it removes debris from the hole and keeps the drill bit cold while it spins. Add a HEPA filter and use a dust bag to make your vacuum cleaner more effective..

Guidelines and Authorizations

Most communities do not require drilling permission if you are only drilling into the brick itself. However, the work may be incidental to something that does require a permit, such as mounting an outside GFCI outlet on a brick wall.

Reasonable Concerns Regarding Risk

It is possible that manufactured veneer brick, which is considerably softer than structural brick, will not offer enough support for fastening heavy things. Additionally, the thickness of veneer brick can range from 3/4 to 1 inch, making it unsuitable for hanging large objects.

Brick walls may include electrical wiring for lights and outlets. Always ensure no wires are in the way before drilling through a brick wall. Turning off the corresponding circuit breaker in the electric service panel will cut electricity to the region.

How to Drill into Brick or Mortar 

Prepare the drill site by measuring and marking it.

Making a mark is necessary before drilling into masonry. A tape measure will come in handy when locating the exact middle of a wall, the ideal height, or the ideal distance between two things.

Mark the brick using a permanent marker, ensuring the writing isn’t too close to the edge. Bricks tend to crack and break apart when drilled close to their borders. So remember to maintain a safe distance of at least an inch from any edge.

Use a bubble level to check that your drill holes are perfectly plumb and level if you need to make more than one.

Finding the Preferred Depth

Put in the right drill bit and screw it in. You probably won’t need to drill through the bit for most jobs. Check the box to find out how deep you should drill holes for a concrete anchor kit or masonry screws.

There are depth limits on several hammer drills that the user can’t go past. To use a drill’s stop effectively, adjust it so that the distance between the bit’s tip and the stop’s end is equal to the depth you intend to achieve. If you don’t have a stop, a permanent marker will do for marking the drill bit depth.

The other option is to use painter’s tape as a guide by wrapping it around the bit at that point.

To initiate drilling, start.

Put on your goggles, mask, and earplugs (hammer drills may be somewhat noisy), and crank up the speed and hammer setting on your power tool (if so equipped).

Once you’ve got the drill’s tip where it needs to be, give the rear of it a couple of taps with your palm. As the drill bit advances, the tap ensures that its tip remains firmly anchored in the brick at all times, preventing it from wandering off the mark.

With the drill held at a right angle to the wall and the trigger depressed, it is possible to bore holes in solid materials.

Allowing the drill bit some time to develop the hole once it has begun penetrating may hasten the process. Then, remove the rotating drill slightly every 10 seconds to clear the brick dust hole.

Repeat this drilling process and pull the bit out until you reach the fixed stop or the painter’s tape.

Fill the hole with vacuum cleaner dust.

Because most modular bricks are solid, the dust collects in the cavity between them. Therefore the presence of dust will hamper any attempt to secure something to brick. Consequently, it is essential to clean it off first.

Get rid of the dust with a shop vac’s hose and crevice nozzle.

The time to sweep and mop the floor is now that you have the vacuum cleaner out. (Don’t mop until you’re through, so the floor isn’t damp and you can work on it.)

Specify a place to nail or nail something down

Use the item’s included hardware, or an anchor and masonry screw set, to secure the item to the wall.

You may use a driver bit for your drill, a screwdriver (though that’s tough on the hands and wrists), or, for hex head masonry screws, a socket and a ratchet to turn these fasteners.

Finish by vacuuming and mopping the floor to remove any lingering brick dust. The abrasiveness of brick dust means it can harm delicate materials like hardwood or tile.

Follow All Required Safety Instructions 

Always put your safety first whenever using any power tool. For example, drilling safely protects you and your coworkers and results in better-made holes. Wear protective eyewear, earplugs, gloves, and a respirator to the job site to reduce the risk of harm.

Put forth the correct effort, but let the hammer drill’s motor do the heavy lifting. Too much or too little pressure will cause the drill to slide, so find that happy medium. Use a force somewhere in the middle.

Don’t wear loose clothing, ever. Long hair, loose clothing, dangling straps, and jewellery are all potential snares for someone operating a power tool. The drill can become hooked on a stray object. Protect yourself on the job by wearing short sleeves and other appropriate clothing.

Make initial holes:

Making pilot holes improves the precision of a straight drill and makes it simpler to install a more significant bit. In addition, if you drill a pilot hole first, you won’t have to exert as much force, lowering the risk of the drill bit slipping.

Install the drill bit:

Drill’s chuck should be snug within the chuck key, so insert the drill bit there.

The best approach is a center punch:

With the help of a center punch, you may make a hole in the material and use it as a reference point for further drilling.

Perform tasks with a drill stand:                        

When drilling into rigid materials like brick or mortar, support can help you get straight holes. Additionally, it stops the drill from sliding.

Utilize protected resources:

Drilling into a brick may cause it to shift, so you should clamp it or secure it in a vice if necessary.

Be sure to protect yourself by donning safety gear:

When working on a wall, use safety goggles to shield your eyes from any loose bricks or mortar that could fall. Protect your hands and fingers from brick shards and your ears from excessive noise by donning a sturdy pair of gloves and a pair of earmuffs. If you want to keep the fine dust from settling in your lungs when working with bricks and mortar, you should definitely invest in a respirator.

Silica, found in bricks and mortar, is toxic in high doses. Inhaled silica particles between 0.5 and 5 micrometers in size remain in the lungs. Lung fibrosis can develop from accumulation over time. Wearing safety equipment does not absolve you of responsibility.

It’s important to regularly inspect and maintain your hammer drill. Inspect the core lock’s balls, bearings, latch, pins, and sure lock’s core casing for any signs of wear. Preserve the life of your drill and drill bit by cleaning and lubricating the moving components as needed and replacing damaged or bent drill bits.

FAQs

Can you drill into the mortar between bricks?

Always drill through masonry unless you’re hanging anything light (less than a pound). While brick may last long without cracking or shifting, mortar can’t take the same abuse and eventually gives up.

How long before you can drill into mortar?

Finding what you need quickly is possible if you know where to search. Afterward, either use cement to set the anchors or just use screws and then back them out when installing the shutters. It’s alright if it takes three days or even the next day.

Conclusion 

That’s all; that’s the quickest and easiest technique to avoid breaking your brick when drilling into it.If you have a brick wall and are considering not hanging anything on it, first determine whether or not the masonry and mortar are sturdy enough to allow drilling.
