Your Guide to the Best Exterior Brick Sealer
Protecting your home’s brick is a smart move. A good brick sealer keeps your walls looking great and prevents damage. This guide will help you pick the right one.
Why Seal Your Brick?
Brick looks good, but it can soak up water. This water can freeze and crack your bricks. It can also lead to mold and stains. A sealer creates a shield. It stops water from getting in but lets air out. This keeps your brick strong and clean.
Key Features to Look For
When you shop for brick sealer, check for these things:
Water Repellency
The main job of a sealer is to keep water out. Look for products that clearly say they are water-repellent. This stops rain and snow from soaking into the brick.
Breathability
Your brick needs to “breathe.” This means trapped moisture can escape. A good sealer lets water vapor out. It doesn’t trap moisture inside the wall. This prevents damage from the inside.
Durability and Longevity
You don’t want to seal your brick every year. Look for sealers that last a long time. Some can protect your brick for 5, 10, or even more years. This saves you time and money.
UV Resistance
Sunlight can break down some sealers. A sealer with UV resistance stays strong even in bright sun. This means it keeps working and looking good for longer.
Ease of Application
Most sealers go on with a sprayer or a roller. Some are easier to use than others. If you’re doing it yourself, pick a sealer that’s simple to apply.
Important Materials
Brick sealers are made from different things. The most common are:
Silane and Siloxane Sealers
These are very popular. They soak into the brick. They create a barrier that repels water. They are also very breathable. This makes them a great choice for most homes.
Acrylic Sealers
Acrylic sealers form a thin film on top of the brick. They can add a bit of sheen. Some acrylic sealers can make the brick look darker. They are good at blocking water but can sometimes trap moisture.
Silicone Sealers
These are also good at repelling water. They tend to be very durable. However, some silicone sealers may not be as breathable as silane/siloxane options.
Factors That Improve or Reduce Quality
What makes a brick sealer great or not so great?
Improving Quality
- Good Ingredients: Sealers with high-quality silane or siloxane are usually better. They offer excellent protection and breathability.
- Proper Formulation: A well-made sealer will last longer and work better. It will be easy to apply and dry clear.
- Manufacturer Reputation: Brands that have been around a while often make reliable products.
Reducing Quality
- Cheap Ingredients: Some cheaper sealers might not last as long. They may not protect your brick as well.
- Poor Formulation: A badly made sealer can be hard to apply. It might leave streaks or change the brick’s color.
- Trapping Moisture: If a sealer isn’t breathable, it can cause problems. Trapped moisture can lead to efflorescence (white powdery stains) and spalling (flaking brick).
User Experience and Use Cases
How do people use brick sealers?
DIYers Love Them
Many homeowners use brick sealers themselves. They spray or roll it onto their house. It’s a way to save money on professional services. The process is usually straightforward.
Protecting New and Old Brick
You can seal brand new brick when your house is built. This gives it protection from the start. You can also seal older brick. This helps to stop further damage and refresh its look.
Preventing Stains and Mold
Sealers make it harder for dirt, oil, and mold to stick to the brick. This keeps your walls cleaner. It reduces the need for frequent power washing.
Enhancing Curb Appeal
Clean, protected brick looks beautiful. A sealer can make your home look newer and more inviting. It adds to your home’s overall charm.
