Caulking is essential for keeping pests, moisture, and drafts out of your home. Whether it’s moisture causing damage to your walls or drafts driving up your energy bills, your home is vulnerable without caulk. 

Caulk can also be used to repair larger gaps and minor damage to your home’s exterior. Prepare yourself before attempting such a task. Keep the following tips in mind as you prepare to caulk large exterior gaps. 

Learning the Basics

Before attempting to close a large gap, make sure you have all of the necessary materials and supplies. Take note that the majority of caulk comes in 290ml or 310ml tubes, so check the caulking gun’s specifications. 

Furthermore, the type of caulk you use is important, and the best caulk for your project will vary. Consider whether large holes and cracks necessitate the use of waterproof caulk (such as silicone caulk) or a flexible gap filler (which expands). 

#1: Learn Proper Nozzle Trimming

The first step in caulking large exterior holes properly is to choose the right caulk nozzle. Inexperienced do-it-yourselfers frequently cut the caulk tube tip straight, but an angled cut is far more effective. A much smoother application will result from cutting the caulk tube’s nozzle diagonally in the direction you’ll be applying the product. With a smooth, even application fills the void perfectly. 

#2: Learn to Bridge the Gap 

Before caulking large exterior gaps, remember to thoroughly clean the gap. Allow it to dry after rinsing with water before applying. A loose fit and an incomplete seal can result from preventing caulk from adhering to the material. This not only exacerbates existing problems like drafts and pest entry points but also has the potential to increase the structure’s ability to trap moisture. 

#3: Learn to Layers Patiently

While it may appear that filling large gaps in your exterior is a daunting task, patience is a virtue. To close a large gap, work in single, well-executed layers one after the other. A good rule of thumb is to caulk a gap from bottom to top in layers rather than all at once. Repeat this process until the hole is completely filled. 

#4: Learn and Follow the Stages of Drying 

As you apply caulk to a gap, allow it to dry between layers. Because caulk shrinks as it dries, it would be best to wait until it is completely dry before applying the next layer to compensate for and fill in the shrunk areas. After each application, smooth the caulk with a damp cloth or your finger. 

#5: Learn to Keep Your Nozzle Clean for Best Results 

To clean the nozzle of your caulk tube, keep a damp cloth on hand! Dry detritus on the end can obstruct a smooth caulk line, reducing your project’s effectiveness and visual appeal. It is far more convenient to clean the nozzle with a damp cloth than to clean the tube later. Simply make sure your damp cloth isn’t dripping wet to avoid clogging the caulk nozzle. 

Conclusion 

If you need to fill a large exterior gap, you do not have to do so on your own. Put your trust in the experts whether you need straightforward advice or want to outsource the task to a professional for the best results. There’s no harm in counting on professionals. This way, you can learn from them and get the value for your money!
