How to Choose the Best Large Gap Filler?
When it comes to choosing a caulk for large gaps, there are a few things you need to take into account. The following guide will help you choose the right caulk for your needs.
1. Type of Material:
The first thing you need to consider is the type of material you will be using the large gap caulk on. Different materials require different types of caulk.
For example, water-based caulk is best for porous materials like wood, while silicone caulk is best for non-porous materials like glass or metal.
2. Size of the Gap:
The next consideration is the size of the gap you need to fill. Not all caulk is created equal and some are better suited for small gaps while others can handle larger ones.
You should also take into account the width of the bead you need. A wider bead will require more caulk than a thinner one.
3. Location of the Gap:
The location of the gap is also an important factor to consider. Some caulks are better suited for indoor use while others can be used both indoors and outdoors. When choosing an outdoor caulk, make sure it is weather-resistant.
4. Waterproof and Weather-resistant:
If you need a caulk that is waterproof and weather-resistant, then silicone caulk is your best exterior caulk for large gaps. This type of caulk can also be used in areas where there is high humidity.
You can also choose a water-based caulk for these areas, but make sure it is specifically designed for use in high-humidity areas.
5. Additional Features:
When preferring caulk for large gaps, you should also consider any additional features it might have. For example, some caulks come with a built-in primer that makes them easier to apply. Others come with a nozzle that allows you to control the bead size.

Filling big gaps with caulk is a simple process that anyone can do. All you need is a caulking gun, some tape, and a few other supplies.
The following guide will show you how to caulk big gaps like a pro.

The first step is to clean the gap. This will ensure that the caulk adheres properly and does not have any dirt or debris in it.

You should hold the tube at a 45-degree angle and move it slowly along the gap. Be sure to apply an even bead of caulk.
Step 5: Let it Dry
