Are your gutters or roofs suffering unwanted leaks and cracks? Well then, the best gutter sealant is definitely the answer to all your problems. Unlike power tools, there are much more options for gutter sealants and a lot of brands to choose from. But how do you know which brand to use for your gutters? In this buying guide, I’ll help you select a great gutter sealant to fix all of your problems.
Factors to Consider
1. Drying Time
Of course, you wouldn’t want a gutter sealant that takes forever to dry. Although drying times vary from brand to brand, all of the products on our list are proven to quickly and efficiently enough to provide a quick fix to cracks or leaks.
The drying time of your gutter sealant isn’t the only thing you have to consider. You also have to take into account the finish of the sealant upon drying. Ideally, you will have a semi-smooth to a smooth finish, not a flaky or crusty one. Thus, I suggest steering clear from cheap or knock-off brands that won’t give you the same quality finish.
Even if this buying guide is especially made for gutter sealants, you also have to consider the other possible functions since you probably won’t be using up the whole can.
Before selecting the best gutter sealant, look at its other functions. For instance, a gutter sealant can also work as a filler for gaps and holes, or a sealant for other things aside from gutters; such as roofs, PVC pipes, masonry, concrete, etc.
3. Sealing Properties
It is a given fact that a gutter sealant has to have great sealing properties. How do you know if a gutter sealer has what it takes to seal all leaks, holes, and gaps? Well, this is what this article is for, right? Aside from reading all our reviews, you can test out a particular brand for its sealing capacity.
On the other hand, how do you know if the gutter sealant is effective? The most obvious method is to see if the leaks are fixed. Aside from that, you also need to determine if the finish doesn’t sag nor drip. In this way, you ensure that the gutter sealant will last long and won’t need a re-touch anytime soon.
Durability of the gutter sealant is hard to test out unless you actually buy the product and apply it on your gutters. However, you can almost immediately tell if the sealant is durable if it:
- Doesn’t crack
- Doesn’t shrink
- Doesn’t crumble
Moreover, a sealant can be deemed as durable if it is resistant to heat and cold. An ideal gutter sealant can resist hot weather of up to 40°C as well as extreme colds. Thus, if your sealant doesn’t dry up and crack in hot weather nor freezes up in the cold—you’ve got yourself a good deal.
Nevertheless, I’ve only included gutter sealants that can withstand both extremes of temperature for your benefit.
