Gutter sealant drying time is not the only factor to consider. You also need to think about how the sealant will look when it dries. A semi-smooth to smooth finish is ideal, rather than a flaky or crusty one. Consequently, I advise you to stay away from low-cost or knock-off brands because they will not provide the same level of quality.
Because you won't be utilizing the entire can, even though this buying guidance is geared on gutter sealants, you should keep in mind the other possible uses as well.

Hybrid vs. Solvent-based caulk
No matter what type of gutter you have, any product that is meant to be used on it must be waterproof. It should be able to endure the ice and debris that come with frigid temperatures as well. "tear-resistant," "abrasion-resistant," and "flexible/elastic" are some of the phrases to look for on the box.
Several of the sealants available now perform an admirable job on metal gutters. These don't always stick to the surface.
Hybrid caulk is typically used on metal surfaces such as aluminum since it is a combination of silicone, polyurethane, and butyl flex caulks.. Both solvent-based and water-based seam sealers can be used. Check the label on the container to see if a particular solvent is safe to use on the surface you're planning to clean.
Ease of application
A broken caulk gun is not uncommon when trying to force sealant through the narrow opening of a tube's nozzle. Get a thinner, lighter caulk or a better caulking gun to fix the problem. We recommend using the latter for gutter caulking. This is the case, as follows.
In general, polyurethane sealants are much more durable than other types of caulk. As a result, gutters, roofs, and other high-wear areas benefit from their use. As a result, the "get a better gun" advise is warranted because of their thicker consistency.
It's a tiny price to pay for their long-lasting properties, but their gooey texture resembling old caulk or old sealant is acceptable.
When using caulks meant for outdoor use, they should be resistant to cracking, sagging or buckled by extreme weather conditions. The temperature range is -200F to 1200F. As a result, the caulk can expand and contract with the substrate material without losing its integrity.
Corrosion-resistant and sun/ozone-resistant materials are also good choices. Silicone sealant should be avoided at all costs.
What kind of caulk should I use for gutters?
The material of your gutter plays a role. For the most part, hybrid caulks can only be applied to metal roofs or gutters. Both metal and plastic can be caulked with solvent-based caulks. Be sure you use a weatherproof and completely waterproof substance.
Outdoors, polyurethane caulk offers the finest results. DAP Polyurethane Caulk and Loctite PL S30 are excellent solutions. Avoid using acrylic latex in any capacity, no matter how tempting it may be.
What caulk do professionals use?
Most experts use acrylic latex caulk to seal their gutters indoors. Use a putty knife to apply, and soap and water to clean up any messes you make.
There are a few things to keep in mind when it comes to caulking metal gutters in the rain. DAP Version 3.0 Caulk is a good alternative for sealing a gutter or roof that has been leaking water. Sealants made of silicone are not as durable.
