Rated 1.0 out of 5.0 by Terrible product do not waste your money I attempted to use the small tube of seamermate on both the inside and outside of the gutter where the roofer had run a screw threw the bottom edge of the gutter. Gutter was dry and clean. The first attempt was to squeeze the seamermate from the tube directly onto the gutter and to smooth the control the material with a clean putty knife. The seamermate stuck to the putty knife and smeared. It had no sticking capability on the inside or outside of the gutter. The next attempt to use seamermate was to use a rubber gloved finger to install seamermate. This was just a mess. The seamermate stuck to the glove and not the aluminum gutter. Money wasted $3.18. Time and energy wasted: Enormous compared to what was to be a simple task . October 18, 2014
Rated 4.0 out of 5.0 by So far so good The old owners of our hope had miter strips (narrow strips of aluminum used as corner pieces) to tie the gutters together at the corner on the home's additions. It makes for a smooth look and a quick install, but it is also a small piece of metal that doesn't cover very much of the adjoining gutters so leaks are more likely to be an issue. One corner was leaking. I picked up some Seamer Mate and Following the directions, I cleaned the seam out as best I could and used a handheld vacuum to get some of the dust out. Then I liberally applied this stuff in the seam and smoothed it out as best I could so the bead wouldn't be so big as to impede water flow. It seems to do the job so far. We had are in another heavy rain just a day after I did this and that corner is not leaking. The only thing is it is a little hard to work with. When you try to smooth it down all of it tends to want to come back up on your glove, finger, napkin, or whatever. Eventually I was able to get it in there by just squeezing the bead out into the seem, waiting a minute for it to start to self settle, then only lightly pressing it in there for even coverage before smoothing the edges out. This stuff isn't like normal caulk where you can stick your finger in there and smooth it out at will. In summary it seems to get the job done but involves a little trial and error to get it to do what you want it to. I'm not sure why the above poster had problems. I wonder if he was a little stingy with the stuff on each seam. Each packet says it is good for two seams but I actually used a full one and then some of a second one to fill the seam completely and smooth it an inch or so in each direction. If you don't use enough you may leave gaps that still allow for a leak. July 12, 2013
