The Best Exterior Caulk To Effectively And Easily Seal The Gap
If you want your paint job to last, you should not skip caulking. It should be done before you start painting your house. Most beginners and DIY painters may not be familiar with this step.
It may not be known to many but caulking has a number of benefits. It helps seal your exterior surfaces against drafts and prevents any moisture from seeping into your home. Caulking prevents your structures and fixtures from getting damaged.
It protects your house from harsh weather conditions, reduces the temperature in your home, and prevents peeling on the corners of your structures. In this regard, we’ve rounded up a list of the best exterior caulk for your reference.
Different Types Of Caulk
A caulk is simply intended to fill-in gaps, cracks and crevices in various parts of your home to protect your home from air, water, insects, and other elements from infiltrating your house. Caulks are usually made of silicone, latex or both. A silicone latex caulk provides an easy application with a stronger material.
A caulk is packaged in a tube or cartridge design. A caulk gun and cartridge produces a more continuous drop compared to a squeeze tube, making it more suitable for small and minor home renovations.
There are different types of caulk depending on where you plan to use it. It varies from interior to exterior uses including roofing, gutters, concrete, windows, plumbing and other outdoor structures. In this case, we will focus on exterior caulking.
Here are some of the more notable differences between a latex and a silicone caulk.
- Latex – A latex is relatively quicker to apply than a silicone caulk. It is also simple to clean up because all you need are just soap and water. In case you need to remove, change or replace it, a latex caulk is easier to deal with.
- Silicone – A silicone caulk, on the other hand, requires careful preparation. You’ll need mineral spirits to clean it up and is harder to remove than latex. It is more applicable to nonporous surfaces and works better on cracks that expand.
The latex material produces less odor compared to silicone. It is flexible to use on both porous and nonporous surfaces. This type of caulk is more suitable for gaps that remain constant.
On the upside, a silicone material is more durable than latex and works well against extreme temperatures and direct sunlight. It also lasts longer.
