Find The Best Paintable Caulk & Caulk Gun For Any DIY Job

If you’re doing home renovations then it’s very likely you’ve either wielded a caulk gun or are about to. Caulking comes in handy whether you want to put the finishing touch on trim and baseboards, seal windows against draughts, or in sealing plumbing fixtures. 

Some jobs will call for specific types or colors, but for the most part, a good brand of paintable caulk will get almost any job finished to your satisfaction.

When working with caulk, you’ll also need to invest in a good quality caulk gun. There are a number on the market, and it might be overwhelming when you start shopping around, so I’ve made it easy and reduced your list to the best that the market has to offer!

What You Need To Know About Caulking...

As opposed to regular caulk, paintable caulk, once dry, allows the paint to adhere for a professional finished look to your renovations. If you’re using a regular caulk, it tends to make the paint run off sporadically, making it look as if you weren’t paying much attention to the job at hand!

Whenever you’re using caulk around drywall or any other paintable surface (such as trim, especially around windows or doors, and baseboards) using paintable caulk is just plain good practice.

You’ll of course want one that fits best with your colors, but as a rule nice white paintable caulk is best, since that’s typically the color of your baseboards and trim anyway, and it will blend in nicely.

You can easily see where you’ve applied it (unlike some clear caulks, which in certain lighting can be hard to locate and can make for a messy result) and fix any mistakes you might have made. (Let’s be honest, it takes some practice to get it right!)

Types of Caulking Jobs Explained

There are many different times when using caulk can aid in the job you are trying to accomplish.

Windows & Doors

caulking window

Filling gaps and cracks around doors and windows is essential to keep the harsh weather outside. Just a 1/8-inch opening around two frames or windows can let in as much cold air as leaving a window open 6-inches. That’s a lot of wasted energy.

You can use the caulk to seal the outside of windows and door frames. It is also good for use around the foundation cracks. The money you spend accomplishing this task will be made back in just one heating season or less.

Invest in quality caulk and weather-stripping for the most successful chance at retaining your energy.

Exterior Caulk

Caulking is used often in exterior paint jobs. It can effectively fill in the spaces where cold air, pests and water will enter the home. Water is dangerous to your home and efforts to seal it out should always be used.

When working outdoors, consider using caulk around the windows, door frames, soffits, fascia boards, brick and even concrete. Just be sure that when you are working with concrete and brick, you’ll want to use a transparent caulk for the best outcome.

Kitchen & Bathroom​​​​

Caulk is useful for filling cracks found between most any two adjoining materials. This can be where the walls meet in a corner, where the bathtub meets the floor or even where the backsplash meets the countertop.

Not every corner in your home is going to require the use of caulk, but there are some that benefit from the added water protection. Consider using caulk wherever water can soak into the foundations or plywood of your home.

This includes the joints within the shower, around the sink and even at the base of your toilet. As a general rule of thumb, any area that can get wet and cause potential damage should be caulked.

Paintable Silicone Caulk

caulk silicon

Paintable silicone caulk is permanently waterproof so it will not break down in water over time. In addition, it is flexible. Regular caulk can freeze in cold temperatures and eventually crack.

Silicone caulk will not shrink whereas regular caulk shrinks as it dries. In addition, silicone caulk is virtually crack-proof. You won’t have to worry about exposure to extreme heat or the sun’s UV rays.

Silicone caulk can be used around windows, doors, trim, molding, vents and siding. In addition, it excels behind sinks, around the tub and anywhere else water could become an issue.

Silicone caulk can be applied to most wood, masonry, brick, metal, vinyl siding, drywall, plaster, laminate, ceramic tile, plastic and glass.

Why Is Silicone Caulk Paintable?

Unlike non-silicone caulk, paintable caulk combines the adhesion and durability of silicone and mixes it with the paintable function of acrylic. Normally, within about 30 minutes of application, you can paint over the caulk.

This can be accomplished with either a brush or roller. If you are using a spray paint gun, you should be able to apply the materials without waiting the full 30 minutes.

Be sure to read the directions on all your caulk before painting. Some varieties may require as long as 24 hours of drying time before you paint.

What You Need To Know About Caulking Guns...

You’ve probably seen the products out there; the tubes of caulk (they look like big toothpaste tubes) that advertise an easy and mess-free way of application.

They look like they might take the stress out of the job, don’t they?

In multiple tests by professional tradespeople, it was found time and again that caulk from a tube tended to shrink, meaning that the space you’re trying to cover isn’t going to get the desired seal.

You’re going to end up having to reapply...possibly multiple times. The shrinkage was assumed to be due to the thinning down of the sealant required in order to squeeze easily from a tube.

The sealant from a tube is meant to be used in combination with a caulk gun, which, on the other hand, can be very thick since the pressure is applied by the gun itself.

Types of Caulking Guns​​​​

There are three main types of caulking guns you’ll come across in your search. The first is a Ratchet Rod Caulk Gun. This is what most home users will use and they feature a rod that pushes the caulk out. Because this system is based on pressure, the caulk will stop moving when you turn it upside down and pull back on the rod.

The next gun is the Smooth Rod Dripless Caulk Gun. You won’t need as much pressure to get the caulk out because it uses a spring-loaded plat lock to push the pressure rod. Simply squeeze the trigger with varying pressures to adjust the flow.

Finally, there are electric caulk guns which are a good option for anyone caulking often. Simply plug it in or use a battery operated model. They are heavy-duty and great for commercial use.

Qualities of the Best Caulk Guns

When choosing the right caulk gun for your needs, there are several factors you’ll want to take into consideration.

Dripless Design​​​​

Some caulk guns will offer this feature to stop the caulk from flowing when the trigger is released. This saves you from having to twist the plunger rod or push any buttons in order to release pressure.


High-quality caulk guns offer a way to easily trim the caulk cartridge to a specified opening size. This saves you from excess mess.

Seal Punch

When you have caulk with the inner foil seal, this built-in punch tool will take care of that easily.

Ladder Hook

If you will be working from a ladder, look for caulk guns that feature this convenient hook which allows you to hang the tube from your workspace.

Higher Ratio

When you are looking for options with less wrist and hand fatigue, you want a caulk gun with a higher ratio. This means when the trigger is pulled, more thrust will be transferred to the shaft.

Open Frame

By choosing a caulk gun that offers an open frame design, you have less weight. This is because there is no longer a need for the cradle which holds the tube.

Which Areas Should Caulking Guns be Used?

caulking gun

Now that you know all the appropriate times to use caulk, you might be wondering when you should use a caulking gun for application. A caulk gun will make the job easier.

You might be tempted to skip using a caulk gun and save the money instead, but it isn’t always a good idea. First of all, most caulk guns aren’t expensive. In addition, I am going to show you that using a caulk gun could actually save you money.

Applying caulk can be a long and tedious job, but not with the right caulk gun. You’ll find that having a proper gun will allow you to get the job done faster which gets you back to your other projects faster.

In addition, using a caulk gun allows you to provide an even application. This saves you from a wasted product like when you attempt to do it without the caulking gun.

So, as you can see, any time or anywhere that you are going to apply caulk is a good place to add a caulk gun in as well. You can save yourself time, money and effort.

Newborn 930-GTD Drip-Free Smooth Hex Rod Cradle Caulking Gun

Best Features

  • check-circle
    10:1 thrust ratio
  • check-circle
  • check-circle
    Prevents dripping

My Overall Rating

This gun works like a dream and doesn’t take any effort to use. The pressure rod requires less force to use than most, and is also less noisy for repeated use (whether you’re new to home renovations or not, there is a bit of stop and go when using caulk guns. With some of them the noise can be a bit jarring.)

The Hex Rod has a steel half barrel frame, which makes it sturdy and resistant to damage. To help prevent the mess associated with caulk jobs, the rod retracts by itself on this one after each trigger pull!

This goes a long way to prevent drips and a huge clean up. Both the handle and trigger are padded, making this the most comfortable caulk gun on the market.


Before using caulk and the gun, it’s important to make sure you cut the tip of the tube of sealant on an angle. A small hole will obviously result in a small bead of caulk, while a larger hole results in a larger bead. Cut according to the job that you want done.

Once the tube is cut, insert it into the cradle of the gun. Now all you need to do is squeeze the trigger (some are more of a pump action) until you see the caulk start to emerge. If you notice that your bead isn’t big enough, release the trigger and cut a bigger hole.

Take your time, have confidence, and get that renovation done with the best the market has to offer!
