Do you need a quick and easy way to seal and caulk your surfaces? Whether you’re looking for a standard sausage caulking gun or a battery powered model, look no further. Here are our top tips to make it quicker and easier to find the sealant gun you need.

Thrust Ratio

Your caulking gun’s thrust ratio will directly relate to the viscosity of the material you use. If you’re going to be using a higher viscous sealant you’ll need a gun with a higher thrust ratio. It’s therefore best to choose a model that has varied speed since this allows it to work with all viscosities.

Dripping

Nobody wants to have to deal with unnecessary mess if they’re using a caulk gun. Dripping is messy and uses up your caulk too quickly. While a lot of models claim that they’re drip-free, this isn’t always the case. This is why reading caulking gun reviews like these is so important.

Precision

Crack filling and resealing requires a lot of precision. You need to ensure that materials can be dispensed equally. This is something that a poor-quality silicone gun cannot achieve. Make sure that the model you choose is capable of accuracy.

Quality

When you choose a high-quality model you’ll find it’ll last for longer. It’ll also be easier to use. A cheap caulking gun will cause you frustration and will break more quickly. Take care to choose a model that fits your budget but that can also offer you the quality you need.

Sausage Gun FAQs

If you’re wondering how to use a caulk gun (1), the good news is that it’s fairly simple. All you need to do is get the caulking tube and cut its tip to the size you prefer. 

Push a nail into the tip so the seal is broken and put the caulking tube over the gun’s plate. Squeeze the gun’s handle and the caulk will begin to flow into the gun’s open side. You are then ready to begin your caulking project.

Sealant and caulking are two different things (2). Sealant should be used in areas which could contract and expand. Caulking, on the other hand, is used where contraction and expansion won’t take place. 

Nevertheless, a caulking gun will work for both sealant and caulking tubes. The process of how to load a caulking gun is also the same for both types of tube.

There are several different kinds of caulking gun on the market today. The electric caulk gun, battery powered caulking gun and cordless caulking gun are just some examples. You can also find manual caulk guns, of course. The right one for your project will depend on your individual needs.
