Last week we talked about a quick, easy fix for sealing leaks at the corner seams of an aluminum gutter system. Today, we thought we’d take a look at several of the sealants which are available on the market. That way, you can make the best choice for your home if you are ever facing a corner seal leak.
There are three best-selling gutter sealants out there: General Electric Metallic Silicone II Caulk, GE Lighting White Paintable, and Rust-Oleum Rubber Sealant.
Rust-Oleum Rubber Sealant
Rust-Oleum might have a lot of merits, but right away we wouldn’t recommend it because it isn’t a silicone based sealant. We’re only including it because it’s a current best seller, and “best-seller” was a useful starting place for evaluating gutter sealants.
As the full name of the product implies, this is a rubber sealant in an aerosol can. Rubber on metal is not going to stand up to the torrential rains that we see anywhere in our service area–if you live in New Port Richey this is the last thing you’re going to want to put on your gutters.
Another problem that we see with this sealant is that the spray-paint application doesn’t necessarily allow for precision leak coverage. A lot of people get very “hit and miss” results with this product thanks to the application method alone.
GE Lighting White Paintable
This product is iffy. It’s an acrylic sealant with a silicone additive. It is not a pure silicone sealant.
People often reach for a sealant like this because they’re concerned about painting over the patch. Of course, you can paint your seamless aluminum gutters any color you want. That’s one of the advantages of having them. But they need to handle water first and foremost, so we wouldn’t choose a sealant based on your ability to make it match your paint color.
Truthfully, if you’re applying your caulk carefully and properly any patches that you make should be barely noticeable from the ground anyway.
Overall it seems to be a solid product, one that works well for a variety of other tasks. We just wouldn’t recommend it for your gutters.
GE Aluminum & Metal Silicone II
This product is totally silicone based and is ready to take on torrential rains with just three hours of drying time. It can handle UV rays, as well.
This is pretty much the only caulk that is truly made to work with something like an aluminum gutter. When you’re sealing a gutter leak you don’t really want a product that’s trying to be an all-purpose item.
We feel pretty confident calling this the best gutter sealant out there. It only costs a couple of dollars more than the other sealants–and we think it’s well worth the cost.
Of course, if your existing gutters are broken well beyond a sealant’s ability to repair it you just need to call us for a free estimate on getting them replaced. Sometimes that’s all you can do!
