When a house starts getting old, it’s common for cracks to develop. These cracks are unattractive, and they can harbour snakes, insects, rodents and other uninvited animals. Plus, they can also allow moisture to enter the house.

For this reason, they need to be sealed appropriately. And that is where caulking comes in. Contractors use waterproof fillers and sealants to seal these cracks and other house repairs.

However, because your house has different parts and components, it’s essential to use the right caulk specific to that part. Today, we look at the best caulk to use on the exterior of your house. Let’s get started.

What Caulking Should You Use Around Your House’s Exterior?

There are different materials available for exterior caulking. Some are easy to work with, while others require specific skills and experiences. Here are some popular types of exterior caulking. 

  • Polyurethane Caulk 

Poly caulk is more together than other caulking materials. They are mostly used in driveways, trim and other places exposed to elements. But, we should mention that this caulk has a gooey consistency. Therefore, it’s not easy to control. 

  • Silicone Caulk 

This was the most preferred material for all types of caulking jobs. It is water, temperature, weather and chemical resistant. Thus, making it an excellent choice for both interior and exterior applications. 

Even though many different caulk types have been introduced, this remains a popular option among property owners as it can be used for several purposes. 

  • Hybrid Caulk 

Hybrid caulk combines both silicone and polyurethane properties to form an excellent material. Well, its label doesn’t exactly bear the name “hybrid”, but you can identify them by looking at the mix of materials. While these caulks are costlier, they are easier to apply than polyurethane. 

  • Acrylic Latex 

Inexperienced caulkers should consider this type as it is very easy to apply. Plus, even finishing won’t give you a headache. 

You can clean these caulks using water hence a suitable option for those who plan to paint. However, choose acrylic latex caulk with silicone as it is more flexible and adhesive. 

  • Solvent-based 

Solvent-based caulks are recommended for gutters and roofing jobs. That’s because sunlight doesn’t affect their quality. Plus, you can apply it on wet surfaces if need be.

The only challenge is that their consistency makes it difficult to apply. Therefore, they need someone with some skill and experience. 

What Affects the Type of Caulking You Choose? 

Certain factors affect the type of exterior caulking you use. These include;

Foundation type– you should identify and repair cracks on your foundation quickly. Otherwise, they can weaken it and lead to high repair costs. Polyurethane, silicone and latex make suitable caulking materials for foundations. However, consider your foundation and check the package labelling before deciding. 

Location- many areas in a home’s exterior can be caulked. But, the specific area will determine the suitable caulk composition. You can’t use the same caulk on doors and gutters. 

Season- the current temperature also influences your decision. Some materials can’t withstand extreme temperatures. While some caulks can be easily set in extreme heat, others can’t. Therefore, you need to choose the right one for the job. 

Final Thoughts 

The type of caulking material you choose on your exterior can affect the overall outcome. Note that these materials come in different shapes and forms. As such, they have varying durability, physical appeal and strength. Therefore, pick the material that matches your needs and preference.
