Hay Shed Painting

Sami23 · 13-09-2019 12:26pm #1

Looking for advice please.
I have a 2 Bay Hay Shed with Lean To that hasn't been painted in a number of years. The last time it was done was probably 15 years ago by "travelling salesmen" so not even sure what paint they used but as you can see from the picture attached all the paint is now gone off it and although it looks very rusty the galvanize is still strong with no holes and I can walk on it.

Could you please advise me on best way to clean it (power washer, wire brush on angle grinder etc.) and how clean I would need to get it (back to bare metal) ?
Whether I would need primer and what paint would be best to use ?
Also what would be the best method for applying paint - corrugated roller, soft sweeping brush or ordinary brush ?

The traveling salesmen are great men for thinning paint and whatever they use to thin it it will pull all coats paint over the years off the shed. I bought a barrel of it one time off an ad in the cork examiner and a man who definitely wasn’t a traveler delivered it. I wasn’t long finding out it’s origin though. The smell off it alone meant That I’d to abandon using it pure poison.

I seen a lad last year spend days with grinder and wire brush in similar state to urs , what ever paint he used the rust is up trough the paint , I assume he used a bad paint and not enough , I’d be using a good primer and give a few coats of shed paint

I dealt with Castle Paints the last twice that I got sheds painted, The last time they recommended a painter and he was very good but no matter who does the job their paint is very good.
I used Travellers once for REPS and they did a good job that lasted 10 years, I then used the same ones again and it ended up in the gutters so that's the reason that I consulted Castle paints for advice.
A Good strong power washer is sufficient, we had bad roofs here and I never used a primer and it lasted as long as on the good roofs
For whatever reason the contractors using Castle paints put about half a litre of white spirits in the 20ltr drum of paint '' to stop it cracking'' both contractors did it, they were putting it through a sprayer

Thanks for the advice wrangler. So you don't think I would need a primer even though its quite rusty. The primer will double the cost of the job as its as expensive as the paint itself but would be worth it if it added years into the life of the job.

The other option would be to re-sheet it altogether and long term I know that will be required but funds are just not there for that at the moment so was hoping painting it will get me sorted for now but just don't want to put the work and money into painting it if it's gonna start flaking/cracking that's why I was asking for advice on what others have done in the past in similar circumstances.

I would powerwasher it take ur time and do a right job on washing it
Then paint it using a soft sweeping brush u could use a painting pole that extends just put few strong cable ties around the sweeping brush tis handy if u have a hard to reach spot
Castle paint is great paint you would want at least 100 litres for roof that size

Yea have got good few suggestions of the soft sweeping brush alright. Any idea what those corrugated rollers would be like.
Will I need to remove all the rust with power washer or just the surface/loose stuff I wonder and again would primer be a necessity?

Primer is up to yourself, we live beside s tidy town so would have to keep it fresh, The last time I painted it was after 12 years and when I had it power washed I was sorry I had the paint bought as it looked alright after the washing
We've sheds here that were built in the 1930s, Painted first time in the 1990s and never used a primer

The corrugated roller can be a pain if u need to put some paint in a corner of a sheet etc the brush will fill up any crack or in between two sheets and a sweeping brush is lot cheaper than a roller
Try take off as much rust and grim as possible if stuff won't come off I won't worrie about it
Never used a primer

Power washer needs to be 3000psi +

Nekarsulm · 15-09-2019 5:10pm

I power-washed a four bay hayshed plus lean-to roof about six years ago.
3000psi washer, did it slow and careful.
Weather was exceptional, steel bone dry.
Castle paints, added a litre white spirits per 20 litre drum, mixed with a whisk in a drill.
Put on with a sweeping brush, didn't spare it.

Feckin rust coming through again...

Wonder is it better sprayed on, there's bad roofs here and no rust after 12 years.

Get good paint on before the galvanise layer is gone.
This shed was built in 1966, and is still rock solid, just the galvanise layer had gone thin.
Probably should have got some kind of primer or rust neutraliser first.

Galvanise will take off paint when it's good, galvanise in good condition has to washed and treated before painting other wise the paint won't stick, there's a special primer for fresh galvanise

Whatever you do, be careful. Too many lads seriously injured from shed roofs, and that’s before the deaths. Couple of lads dead this year falling off/through shed roofs.

I've to take down a 60ft aerial off the cattle shed and 30ft aerial off the house.
I can get a truck mounted cherry picker for €300 for the day, I'd be some fool to try it on ladders

bought a 10l pressure pot lately for spray painting the new place. spraying water based paint at moment with it. doing a 7m x 5m walls and ceilings in 45 mins . took near3 hours to roller it

Going to chance painting the hay shed with the pressure pot next year after a good washing. I wash with the hotwash and when its fully washed I mix up a gallon of Milton into the last 50 litres of water and coat the shed quickly. it will keep stuff growing on the clean metal until painting

I use Fleetwood oxide here in 5 gallon drums . 8 years since I done the shed and its grand except the roof which I didn't wash at the time

10l Jefferson pressure pot is the set up

Was the galvanise in good condition or rusty before you painted it and did you use a primer 1st

bit of rust in places if im honest. No I just put it on with a brush and also corrugated roller. but if im spraying ill put on 2 coats as cant put on the paint as heavy.

Dad thinks we should be able to paint it twice in about 4 hours a coat out of a cherrypicker/teleporter basket

Was it just the 1 coat you gave it and how did you find using the corrugated roller as a lot of people are recommending a soft sweeping brush for the job

yes i gave 1 coat but a good heavy coat. corrugated roller was ok, but like that I heard about the soft brush since and a lot cheaper also

my 2 bay shed used 3 x 5 gallon drums
