3 Best Caulk For Exterior of House

The best caulking for the exterior of the house is a very important part of the construction of your home, and it is also one of the most difficult parts to do.

The reason why it’s so hard to get right is because you need to make sure that all of the seams are sealed properly. If you don’t seal these joints correctly, moisture can easily enter into the wall and cause rot or mold growth.

This will ruin your walls and floors, which means that you’ll have to spend money on repairs.

To avoid this problem, I’ll discuss in this article three types of caulks that are suitable for the exterior of your house, the pros and cons of each, and one caulk that you should avoid.

GE GE012A All Purpose Silicone 1 Sealant Caulk

This is the first type of caulking that we’ll be discussing today. GE GE012A All Purpose Silicone 1 Sealant Caulk has been explicitly designed for use outside, but it’s great for interior applications as well.

This product contains silicone and water-based polymers, making it flexible enough to fill cracks and gaps without leaving any sticky residue behind.

It dries clear, meaning there won’t be any white marks left behind after the application.

What Are The Best Caulks For The Exterior of A House?

So, these are the best three caulks for the exterior of the house;

  1. GE GE012A All Purpose Silicone 1 Sealant Caulk
  2. Sashco BigStretch Acrylic Latex High-Performance Cementsitious Caulking Sealants
  3. Gorilla 8060002 100% Silicone Sealants, 10 oz, White

But if I would pick one out of these three, I would go with the first one. This is the most recommended one as it’s the best quality and the easiest to use.

However, I would avoid the 3M Scotchgard Paint Primer – Water Based Spray Adhesive, 16 oz, Blue because of its low customer reviews.
