Re: Best maintenance for rain gutters

try installing plastic screens between the roofing and the gutter. this will prevent dried leaves from getting stuck and clog them..these screens are now commercially available, 12" in width and i forgot how long they are.

rivets will do for this job.

Re: Best maintenance for rain gutters

Yes. Number one rust cause is the prolonged wetting due to damp leaves that accumulate on the gutters.

I also apply epoxy-based paint on my gutters. They last a lot longer.

Yes I've done this already before and its really effective, actually I used the welded chicken wire with hole size of 1/2" X 1/2". Maybe my mistake then was I did not repaint the inside of the rain gutter. :rolleyes: Thanks doc v for your inputs. :p

Absolutely true in did, with those damp leaves stock on the gutters really would cause rotting or rusting of the galvanizes gutters. So I guess periodical cleaning of the gutters should be done specially if your house is surrounded by trees like ours.

Any special brand of epoxy based paint for the new galvanized gutters before I install it sir ding or any from nearby hardware stores?

Thanks too for your inputs. :p

Re: Best maintenance for rain gutters

I recall I just used Sphero. This is automotive primer. Not sure if there's any brand specific to roofing. The brand was recommended by a house painter so it is just based on his experience and not on any technical knowledge. Please feel free to debunk me if this approach is wrong.

Re: Best maintenance for rain gutters

Ok then I'll just visit the paint store near our place and talk to the owner/manager if the Sphero brand will work as a good coating for the new rain gutters.

Thanks again.

Re: Best maintenance for rain gutters

Forgot to warn you about epoxy paint. They dry so quickly and even more so on a hot day. Best to paint early in the morning when gutters are cool but make sure they're dry. Painting under the heat if the sun makes the epoxy paint cure fast and you'd end up using lots of brushes. Mix a small amount at a time. Use dirt-cheap brushes.

This concrete gutter's watertight after using flintkote:

But in a year, the bitumen's gone!

The contractor did a bad job, leaving the chb exposed to the elements. I'm going to have this fixed, palitada, waterproofing, the works. Then another layer of bitumen. I think it's the UV damage that kills the bitumen, they recommend aluminum paint over the bitumen in these situations, but i wonder if it's cost effective.

Re: Best maintenance for rain gutters

Please do post your works for that, some might be interested on the step-by-step process.

@zepol

Shell Flintkote bitumen is not UV resistant. It serves as a primer only. You need to top coat it with shell flintkote Ultra with Fiber Mesh, then put concrete topping.

You also might want to consider Boysen Acqua Epoxy

UV resistant, according to the manufacturer. Bought a couple of 4-liter cans, around 900 each. Haven't had the chance to apply it yet.

@joey81
I have a feeling the aqua epoxy isn't for roofs and gutters. It's uv and water resistant, but the uv and water on roofs are something else.

@bryant
So it's OK to palitada on top of the bitumen? That would be convenient, since I have to palitada the sides and tops of the gutters anyway. I'm sure cement provides very good uv resistance hehe.

But in the long run, will i have problems digging out that palitada when the time comes to re-apply bitumen? Or does the bitumen layer separate the concrete topping from the underlying concrete, so that nakapatong lang yung mga layers and they're easy to remove? If i understand correctly, the concrete topping is just there to prevent erosion and sun damage?

I'm toying with the idea of putting the bitumen coat as you described, then laying old vinyl tiles on them prior to the concrete topping. That way, when the time comes, it won't be a big deal to remove the topping so that i can refresh the bitumen layer. It's a crazy idea but maybe it'll pay off 5 or 10 years later

Thanks

Re: Best maintenance for rain gutters

concrete gutter repair
first step, remove spalled concrete, then re palitada (with sahara mixed into the plaster)

after the repairs:

Once that's cured, i'll prime it with bitumen
