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.
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. 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. 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. A polyurethane, acrylic latex, and silicone caulk best serve all sorts of bricks. 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. Lastly, look up the time frame of effectiveness that a caulk formula promises. Do you? On average, a caulk formula promises years of services, which can range from 2 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. 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.
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:.
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.
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. 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.
Once the gap gets sealed, the caulk also functions as an insulator. It traps the warm air indoors. With the 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.
So, the usage of caulk prevents this situation and conserves financial resources. Now, the application is super simple. Just prepare the surface by cleaning it thoroughly and placing masking tape and newspapers wherever need be. Also, remove off the previous layer of caulk if the gap comprises it. Next, prepare the caulking gun and apply the caulk formula. Additionally, before beginning with your project, make sure you look into the weather forecast.
Caulk does get old with time, and you may have to replace it. In other cases, the caulk may get damaged due to severe weather conditions. Well, you can certainly not apply another layer of caulk on it. Doing so will reduce the effectiveness of the product, and the brick wall will appear ugly. 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. Now, gently scrape away the caulk using a paint scraper. Be vigilant as bricks can get damaged. Its strong bristles will remove the semi-liquid caulk easily. After scraping, you might notice the caulk at the base is still firm and sticking to the surface.
To soften it, use a quality mineral spirit. There is no specific quantity, and you may use as much as needed to soften it. 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. 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.

Siding is often textured, and if you slide the tip of the tube along the bumpy texture, the bead of caulk will also be bumpy. The best way to smooth the bead is to start about six inches from the bottom and smooth that small section first. Then, move up another six inches and smooth that section next, pulling downward toward the section you just smoothed. Amateurs often try to smooth the entire bead at one time, which causes excess caulk to build up and overflow on the sides of the seam.
Smoothing just a small section at a time will give you a professional look and prevent a mess of excess caulk on the sides of the seam. It takes caulk a couple of hours to start drying, so you should have ample time to smooth in this manner. Then, run the bead of caulk and smooth it off as described above. If applied to large gaps, caulk can sag out of the gap and create an unattractive mess.
