While there are caulking products that let you caulk cracks and gaps in your home, not all of them has the precision that a caulking gun can provide. When it comes to sealing joints, cracks and gaps, it’s imperative that you provide precise sealing in order to prevent water from leaking in these areas. This also ensures that your caulk is strong. A strong seal is needed for structural support.
If you are caulking moldings, for instance, you don’t want the molding to fall off easily because caulking was inadequate. Uneven caulking is also unsightly and that is what you want to avoid when doing professional caulking jobs.
You should also caulk cracks on walls and damages on siding before painting over them. Cracks look prominent and unsightly when painted over so it’s important that you achieve a smooth surface before applying paint.
Unlike when using manually operated caulking products, a caulk gun effectively controls the flow of the caulking material, expelling just the right amount of material so that you are applying it evenly. Also, a caulk gun is a good addition to your home improvement arsenal because of how easily it can get this job done. It prevents wasting a lot of caulk product as well.
We recommend that you get commercial-grade caulking guns to last you longer compared to cheaply-made caulking guns that might only last for a few uses. Invest your money on well-built caulking guns that are known for their efficacy in producing stable results, ease of use and durability. These are exactly the properties we set out to find in the caulking guns out in the market today.

Caulking Gun Buying Guide
We know you might need more information on how to find the best caulking gun for your needs. Here are the things you need to keep in mind:
All-Around, Multi-Purpose Sealant
Make sure you get the most out of the caulking gun you are buying by choosing one that works with different kinds of materials. It should work not just with caulk but also with other adhesives and sealants like acrylic, epoxy and latex.
Cheaper caulking guns might only work with caulk as they are not designed to work with materials that are thicker or more viscose. This is why you should still check to see if the caulking gun has all these properties.
Size of the Cartridge
What size of cartridge does it work with? You would want to find out if the caulking gun fits standard caulking cartridges. This is true especially if you are going for the sausage type. Otherwise, you will have a difficulty finding a cartridge that will fit in there.
The reason why you would want to use a caulking gun instead of just using those caulking products that can be directly applied is, so you can get consistent application. A consistent amount of product is being dispensed so you can get the same caulking thickness. Just make sure the tool you are using has this feature. Some caulking guns may also have adjustable speed, so you can go as fast or as slow as you want.
Caulking might seem like a simple job but if you are going to do it for a long time, it can still lead to fatigue. To ease up the tiredness you might feel, look for a caulk gun that you can handle easily. The trigger shouldn’t be too stiff. Check to see how well your hands fit the handle. You should be able to move your hands easily without suffering from hand fatigue.
While there are definitely cheap caulking guns out there, you would still want to make sure that you are buying a good one regardless of the price. Chances are, a cheap caulking gun won’t be able to withstand multiple uses, so you still would want to look for one that may be a little more expensive but will work for a longer time.
Backed by the Manufacturing Company
Does it come with a warranty? If it’s a high-end or commercial grade caulking gun, you would want to check if it comes with a warranty and how long the warranty is. The manufacturing company will take care of replacements or repairs in case the one delivered to you fails.
