Alcoa steel siding is peeling

6 posts in this topic

I had Alcoa steel siding put on my house about 18-20 years ago. There are two sections that are peeling badly. The are on the south side of the house and above a one story section that has a dark brown roof. I thought at first it may be from the heat reflected off the roof, and then thought it may have been a bad batch since it would have been logical to have put stuff from one box onto this area - it is seperated by a chimney.

In the past week I have had two other folks tell me they have the same problem with their steel siding. Both were about the same age but the owners didn't know if it was Alcoa siding.

Anyone have any experience in dealing with this? Alcoa HSOforum indicates they sold the siding side of their business in 96. I was told if any warranty applied it would only cover material, which won't amount to anything at all if I have to replace this. I used a wire brush on an angle grinder and stripped it off and have applied the best paint Abbott paint sold.

I also had the same problem on the south side of my house. The house is less than 10 years old. I was told that I sould read the fine print on the warrenty papers which states that the warrenty is only good for the first homeowner and I am the third. I was also told that painting it would only last a year. So I had to reside the side of my house and garage.

So I hope the painting works for you!

Yep, time for a "repaint" or a new siding job. Even baked on paint finishes fail over time. 20 years is a long time to go through the heat/cold cycle we have here in MN.

The trouble with painting over metal siding is the original paint. The stuff that has not failed already (peeled off) will eventualy. The new paint will not stay on the wall if the old fails. It is an endless cycle once it starts and you will be painting every few years. frown

The baked on metal finish is great for a long time, but it has a service life, just like everything else.

I don't think this should be happening no matter how old it is. The rest of the house looks fins. I knocked this off with an angle grinder and a wire wheel and am painting it.

You can definitely paint the siding. Remove all peeling/ failed coating with pressure wash. Sand down any edges with 120 grit alum.oxide. Spot prime with a metal primer. Sometimes the rattle can primers are easiest. Top coat with a high quality paint like SW Duration, which has a lifetime warranty!? Then find another project wink

    • You have no idea....               Suck it up, buttercup...  
    • That was obviously his Republican side...
    • lambjm - keep at it. If you do, you stand a great chance of fishing for possibly decades to come.    Inspirational to me, and hopefully others, is our 85 year old neighbor in Hovland who finished up logging our land this past spring. He logs in a one man operation every day, except Sundays, and a nice day every now and again to fish with his wife.    He has been logging continually for 66 years.   Like clockwork he gets to the landing everyday by 8:30, takes a 15 min break at 10:30, a half hour lunch break at 12, and a 15 min break at 3 before quitting at 4:30. A few days last winter I was out on the land making firewood and clearing trails, and could barely keep up with his schedule. He plans to keep at it as long as he is able.    My wife and I saw him last winter, as we rounded the corner of our road, standing atop a 10' pile of aspen logs with a cant hook or axe in one hand, waving with the other. He appeared as a man less than half his age in terms of agility and stature.   Genetics are a key, but staying interested and active in an outdoor activity is very important to a long and healthy life.     
    • That is because he was fooled into believing in trickle down economics and the idea that cutting taxes in and of itself would solve the budget problem.   Some are still fooled today.
    • Starve the beast, only the beast got stuff on credit.   Reagan didn't seem to be concerned too much about debt.
    • We already know Uncle Bill's response though:  
    • That is a very nice Pimple spear!   They are hard to find. I bought a couple of them from Jerry Kelm. He said Pimple used spring steel from hay rake tines to make the spear tines.    I have not seen one in person with chromed or nickel finish like that, but there is a picture of one that looks exactly like yours on page 215 of  the book "Ice Fishing Spears" by Marcel Salive. I actually wonder if it is the same spear. I heard Mr. Salive was selling off some spears about 5 years ago.    Are you going to be our tomorrow? If so PM me and I will bring the book out to give you a look. TS and I are going to out in the morning.
