Instead, the GE Sealants & Adhesives GE5000 Advanced Silicone will allow you to deal with it all independently. How so?

Thus, allowing the users to conveniently fill in the gaps without shaky hands or an out-of-control flow. Once applied, it will dry up in less than 30 minutes.

Moreover, the product comes with a 10-year-long mold-free warranty. No matter how moist the surrounding air becomes and no matter how much it rains, the caulk will retain its firmness and freshness. It will remain protected from the attacks of mold and the accumulation of its particles.

There’s just one teeny-tiny compromise with this product, i.e., it’s not usable for the brick surfaces that are visible out on the front porch or even in the house. You can use it for hidden or less-traffic areas of your place. Perhaps, the corners, nooks, or rooms that your guests don’t visit or get to see often.

Why? Well, that’s because GE5000 advanced silicone sealant is one of the non-paintable caulks. You cannot paint it with wall-paint, poster-paint, or any other paint to blend it in the surroundings. Instead, it will retain its original form that it will be taking upon drying.

  • 10-year mold-free protection
  • Weatherproof

Read on to gain an insight into purchasing the perfect exterior caulk for bricks!

Know the Four Common Exterior Caulks for Bricks!

As mentioned above, the product competition in the market is high. Each brand has brought forward a different exterior caulk, using a different formula. However, there are only four common exteriors caulks for bricks (material-based). These include:

Acrylic Latex

Acrylic Exterior Caulk For Brick

Perhaps, the cheapest exterior caulk available in the present times is Acrylic Latex. Usually, you can find it between the range of 2-5 dollars. The Acrylic Latex caulks allows an easy application. Plus, you can clean it using water.

Polyurethane

Caulks consisting of polyurethane in its composition make it tough. It is quite sturdy. Once applied, the gap will remain sealed for a long period.

However, it has a semi-liquid consistency that can make application difficult. While professionals might deal with it easily, house owners getting the project done themselves can have a challenging time. Similar to Acrylic Latex, it is available at cheaper rates.

Solvent-based

As the name recommends, the solvent-based caulks cures on the evaporation of the solvent. Usually, the solvent includes mineral spirits. These caulks have strong heat resistance and do not deteriorate under direct sunlight. Unlike others, these are available at mid-range prices.

Hybrid

The most expensive exterior caulk on the shelf is the hybrid as it gets engineered to produce specific results. It combines various materials for outstanding flexibility, durability, and adhesion.

Choosing the Best Exterior Caulk for Brick

So, you’ve been reading all this through but still have no idea which product to go with? Well, we see what’s the issue here. Only knowing about the best variants of exterior caulk for brick will do you little to no good if you do not know what to assess.

If you are new to exterior caulk and are not familiar with what makes up a great caulk, then here is a detailed buying guide for you, which covers all essential aspects to consider before making the final purchase.

Gap Sizes

Perhaps, the first & most important factor to consider is the gap size that you wish to cover. By standard, exterior caulk fills up gaps ranging from 1/4 – 1 inch in bricks. So, you need to check if the gap that you wish to fill falls within this range or not.

If the gaps are wider than this, you may need to make use of a backer rod along with suitable caulk formula. Fundamentally, a backer rod is a soft coiled tube that comes enclosed in a bag, in varying diameters. Just choose a size that’s slightly bigger than the gap, fit it in, and apply the caulk over it.

Surface to Caulk

Using Caulk on Brick

There’s a variety of surfaces to which various caulks cater. However, here we are talking about brick surfaces solely. And so, the surface variation that you may witness will depend on the type of bricks.

These types include:

  • Sand lime Bricks
  • Burnt Clay Bricks
  • Concrete Bricks
  • Firebrick
  • Fly Ash Bricks

A polyurethane, acrylic latex, and silicone caulk best serve all sorts of bricks. However, when purchasing, make sure you look into the manufacturer’s guidelines and recommendations about the surfaces.

Ease of Application

Next, consider the ease of application, especially if you are a beginner and don’t have an expert around. You need to ensure that you will be able to use the product that you’re about to purchase.

For this, you can check out the application instructions provided by the manufacturer. Also, check out the drying and curing time of the caulk as it can greatly impact your schedule and occupations. The shortest drying time that caulk can take is of about 30 minutes. However, some caulks may even take about five days to dry. If we talk about the average, then all caulk usually takes 24 hours to dry.

Maintenance Requirements

Lastly, look up into the time frame of effectiveness that a caulk formula promises. You don’t want to engage yourself in the same demanding process of caulk application over and over again. Do you?

On average, a caulk formula promises years of services, which can range from 2 -10 years. Any caulk that lasts less than this is certainly not an option as it only increases the unreliability factor.

Some authorities in this domain also claim the average lifespan of a caulk formula to be as long as 20 years. Hence, it mostly depends on the manufacturing company’s dedication and the chemical properties of caulk.

In the same regard, we suggest paintable caulk over non-paintable caulk. Exterior caulk is visible on the outside, so non-paintable caulks can significantly impact the overall aesthetics of your place. A paint layer also provides an additional layer of protection to the applied caulk.

Advantages of using exterior caulk for bricks

In case you’re considering skipping the caulking process, please do not. Large cracks and gaps can weaken the building’s foundation. It can collapse at any moment. Hence, delaying or postponing the procedure is very risky, especially if people are present inside. Here are the top advantages of using exterior caulk for bricks:

Mends Every Gap

Caulking the surface is the only solution for cracks that get used by professionals too. If you take services from a repair agency, they will also mend the surfaces using the caulk. Unlike other products, caulk seals all the gaps existing between two surfaces. It strengthens the surface against damage caused by moisture build-up and temperature changes.

Easy-to-use

There are several variants of the exterior caulk available at the market. While some can be difficult to work with, there are quite simple. For example, some caulk use only water for clean-up. Hence, making removal easy. Similarly, different caulks have different properties for increased convenience.

Versatile in nature

Apart from bricks, you can use exterior caulks on a variety of surfaces. Be it outdoors or interiors; you can use caulk to seal any gap anywhere. However, a few caulks work on a specific surface. You must not use these on other materials to avoid any mishap.

Energy Efficient

Once the gap gets sealed, the caulk also functions as an insulator. It traps the warm air indoors. With temperature remaining constant, the heating system has to work less. Hence, conserving energy and reducing bill costs. Moreover, gaps and cracks can lead to the destruction of the building. Once damaged, you’ll have to pour in lots of money for repair. So, the usage of caulk prevents this situation and conserves financial resources.

So, how will you remove the hard and firm old exterior caulk from the brick wall cracks? Read more to find out!

STEP1 – Heat the Caulk

Like any other substance, caulk changes states of existence too upon intense heat application. So, while removing caulk in its solid-state can be trouble, changing it into semi-liquid would solve the issue.

Begin by heating the old caulk area using a heat gun. Avoid using a heat gun near flammable objects, such as a wooden door frame. It will turn into a putty-like consistency.

STEP2 – Removal Time

Now, gently scrape away the caulk using a paint scraper. Be vigilant as bricks can get damaged. If the scraper doesn’t work, select a wire brush to do the job. Its strong bristles will remove the semi-liquid caulk easily.

Once soft, use the scraper to get rid of all the old exterior caulk. Note, when working, use thick gloves to protect your hands. Also, when using mineral spirit, ensure the area has good ventilation.

How to extend Exterior Caulk's lifespan?

Since exterior surfaces have constant exposure to harsh weather effects, they’re likely to experience a greater rate of deterioration. For this very reason, you ought to pay great attention to the precautionary measures that could help you extend the exterior caulk’s lifespan.

To begin with, what you can do is, use a professional caulking tool to smoothen the caulk beads. Smoothening will help it settle well into the gap and consequently hold its position firmly for a long time. For horizontal gaps, you can use self-leveling caulk mixtures to achieve the same purpose.

Also, clean the surface thoroughly before applying the caulk. Dirt particles can keep the caulk from performing its function efficiently. And they may even become a reason for the caulk coming off way before you’d expect it to.
