Brick has been a go-to building material for centuries, and for good reason. It's durable, low-maintenance, and naturally beautiful, whether it's lining the front of a home, forming a backyard grill, or framing a fireplace. When it's time to buy, though, many people are surprised to learn that not all brick is made for the same job.

Face brick, common brick, and firebrick each serve a different purpose, and picking the wrong one can lead to cracking, crumbling, or a finish that just doesn't look right. Below, our masonry supply team breaks down the differences between these three types so you can choose the right brick for your next project with confidence.

Understanding Why Brick Type Matters

Brick remains one of the most trusted materials in residential construction. According to the U.S. Census Bureau, masonry products like brick, stone, and concrete block make up roughly 20 to 25 percent of the exterior wall materials used on new single-family homes. That popularity means there are plenty of options on the market, and each one is designed with a specific use in mind.

The main differences come down to appearance, strength, and how well the brick handles weather or heat. A brick meant to be seen needs a consistent look and strong weather resistance. A brick hidden behind other materials doesn't need to look perfect. A brick that lines a fireplace has to stand up to extreme temperatures. Knowing which category your project falls into is the first step toward buying the right material.

Getting to Know Face Brick

Face brick is the brick you see on the outside of homes, retaining walls, columns, and other visible surfaces. It's made to strict standards for size, color, and durability, so walls look uniform and hold up to years of sun, rain, and temperature changes. Because it's meant to be seen, face brick is usually free of major chips, cracks, and color inconsistencies.

Face brick is also graded for weather resistance. Bricks rated for severe weather are better suited for areas with freeze-thaw cycles, while moderate grades work well in milder climates. For exterior walls, planters, and other surfaces exposed to the elements, face brick is generally the best choice because it combines good looks with long-lasting performance.

Choosing Face Brick Colors and Textures

One of the biggest perks of face brick is the variety. It comes in shades ranging from classic reds and warm browns to soft creams, grays, and whites. The color depends on the clay used and how the brick is fired, which means there's often a natural range of tones from one brick to the next.

Texture plays a big role too. Smooth brick creates a clean, modern look, while wire-cut, sanded, or tumbled finishes add character and a more rustic feel. When choosing face brick, it's a good idea to view samples in person and, if possible, see them in natural light. Our masonry supply staff can help you compare options and find a look that complements your home or project.

Understanding Common Brick

Common brick, sometimes called building brick, is designed for strength and structure rather than appearance. It's typically used in places where the brick won't be visible, such as the inner layers of walls, backing behind finished surfaces, or foundations covered by other materials. Because looks aren't the priority, common brick may have small chips, color variations, or rougher surfaces.

That doesn't mean common brick is low quality. It's still durable and dependable, and it's often more budget-friendly than face brick. For projects where strength matters more than style, it can be a smart, practical option that keeps material costs in check.

Using Common Brick Where It Fits Best

Common brick works well for structural walls that will be covered with stucco, plaster, or another finish. It's also a good fit for backup walls, garden structures that won't be on display, and other utility projects. Some people even use it for rustic designs where an imperfect, weathered look adds charm.

However, common brick isn't usually the best choice for exposed exterior surfaces in harsh conditions. Since it isn't always held to the same standards for weather resistance as face brick, it may wear faster when it's exposed to constant moisture or weather. If you're not sure whether common brick will work for your project, our masonry supply experts can help you weigh the pros and cons.

Exploring Firebrick for High-Heat Projects

Firebrick, also called refractory brick, is made to withstand extremely high temperatures without cracking or breaking down. It's made from special clays that hold up far better under heat than standard brick. That makes it the go-to choice for lining fireplaces, fire pits, wood-fired ovens, outdoor kitchens, and kilns.

Regular brick isn't designed for direct, repeated exposure to intense heat. Over time, it can crack, spall, or crumble when used in a firebox. Firebrick, on the other hand, can absorb and hold heat, which is why it's so popular for pizza ovens and fireplaces. It's usually lighter in color and comes in different densities depending on how it will be used.

Pairing Each Brick With the Right Mortar

Choosing the right brick is only half the job. The mortar you use matters just as much. For face brick and common brick, standard masonry mortar is typically used, with the type chosen based on the strength and flexibility the project needs. Matching the mortar to the brick helps prevent cracking and keeps walls strong for years.

Firebrick requires a different approach. Standard mortar can break down under high heat, so firebrick is usually set with a heat-resistant refractory mortar designed for fireplaces and ovens. Using the wrong mortar in a high-heat area can lead to failed joints and costly repairs. When you shop our masonry supply store for brick, it's smart to pick up the right mortar and supplies at the same time.

Matching Brick to the San Antonio Climate

South Texas weather brings its own challenges for brick. Long stretches of intense sun and heat can fade some finishes over time, while heavy rain and humidity test how well brick handles moisture. Occasional hard freezes, though less common, can still damage brick that isn't rated for freeze-thaw exposure.

Choosing a brick with good weather resistance helps your project look great and hold up through every season. Lighter colors may reflect more heat, while darker brick can add a bold look but may absorb more sun. Considering your local climate before you buy helps you get the most out of your investment.

Estimating How Much Brick You Need

Before you buy, it's important to estimate how much brick your project will require. Start by measuring the length and height of each wall or surface, then subtract openings like windows and doors. Brick size and joint thickness also affect how many pieces you'll need per square foot.

It's always a good idea to order a little extra to account for cuts, breakage, and future repairs. Buying everything from the same production run also helps keep color consistent across the project. Our masonry supply team can help you calculate quantities and make sure you have enough material to finish the job without delays.
