Fence spraying using a compressor

[Parm]

Is this some new high tech undergarment which will shock if you watch?

I hope not. It usually worn iron the wrist

As said over spray can be brutal, but if managed spray gun all the way! I am currently spraying my fence panels as I build them using cuprinol ducksback, this is very thick stuff and specifically says not suitable for spraying.
I'm not letting a tin tell me what to do! So bought this
Spray Gun HVLP High Volume Low Pressure (Gun 1.8+2.5mm Nozzles) https://amzn.eu/d/5pVYc43 ( if that works) think the price has gone up but a spray gun with a 2.5mm nozzle works great. Flow restrictor wound all the way back, just adjust the pressure and pattern. No need to water down of strain the paint, 2.5mm is very forgiving when it comes to lumps
Also found the ducksback can keep in the gun for a few weeks so no need to clean after every use, handy for my situation where I'm only getting time to build a panel a week...

I have sprayed one panel so far,
Devilbis JGA, 1.8mm nozzle I think,
Cuprinol Ducksback, thinned 60% paint 40% water,
Its water washable, so a bit of a farce I think,
"Weatherproofs up to five years" its to late to tell by then
But it sprays on lovely,
6ft x 6ft panel, 3 coats, both sides, 1 litre of thinned down Cuprinol Autumn Gold used.

edit: I'll post a before picture later
edit: 60 psi hose pressure, 40 psi at the gun.

I dont like spraying. Last summer i bought a spray gun and after some advice from here i (sort of) learned how to spray paint some furniture

Im still picking out Farrow and Balls finest soft white eggshell from my black G shock watch

For me with limited skill and knowledge, I've concluded that spraying goes everywhere apart from where you want it to

HVLP spray gun makes virtually no over spray, or spray dust. I painted a small car body inside my workshop once and the only mess was limited to a 3' radius around it.

Normal spraying, even with aerosols, you end up with everything inside the workshop covered in a fine dusting of whatever colour you used.

It depends how you use the gun,
You do get over spray,
But you can make it a lot less with trigger control,
One of my vehicles was parked 20 feet to the right side, no overspray on it, though it was dirty, from sitting in the garage, but yesterdays rain cleaned it lol, that is another story.

You get over spray if you miss the target, but mine only runs 23psi at the gun, so it doesn't go very far.

Did you try it undiluted? It is thick but might surprise you. I was apprehensive at watering it down as it's got wax in it and don't know how that would work? The wax really does work though, the water beads up on the painted panels and rolls off.
Out of desperation I tried it in my little 1.2mm touchup gun to see if it would spray neat, and it did! Took a bit of pressure to get it out but worked. That's when I upgraded to the big one, not tried the 1.8 nozzle though. Here is part of my panel production line, double sided hit an miss painted inside and out, 2l of paint per panel! (Harvest brown)

I only use my HVLP's for car paint,
I'm not putting crap through them,
The JGA is too good really lol.

I'll try it neat, as you say,
I was going to have a go today,
But rain is forecast.

Your panels look good.

I must be a right tight a**e
I only used 1 litre mixed with water for both sides, 3 coats each, lol

I'll have to do a test to see if its still waterproof, after being applied diluted.

I've been blathering ducksback over my sheds every year or two for the last decade or so, mainly because when local DIY sheds flog it as buy one get another, I buy a few.

Shed shows no sign of rot.

 

[Ross365]

Could I ask a question about peoples' experience with the modern water based coatings? It seems to me that when you apply them to new fence panels, everything is fine. But after a few years, my experience when you want to re-coat, there seems to be a problem of poor adhesion, and pretty soon, your re-coated fence looks pretty poor? I saw a post on another forum, saying exactly this, and the lady-poster said she was absolutely in tears about it after all the effort that had been wasted.

So, are there any "tricks" to getting good re-coating? I note that nobody has thrown the use of "Creocote" in to this conversation???

I can only repeat what I said about Ducksback - " blathering ducksback over my sheds every year or two for the last decade or so" - goes on, stays on, water runs off, shed looks same colour all over and shows no signs of going rotten after decade or so - one of those Tiger sheds slagged off on the shed thread as "cheap" . . .

The rain never came to anything,
I managed to spray six panels this afternoon, plus the one I sprayed the other day.
I didn't take Chris's advice, and thinned the paint, about 30% water added this time.
It also needed sieveing, some nasty stringy blobs of I do not know what, after that it was fine.
I did wonder if it was the water causing the blobs/lumps. But the new tin was like it before any water was added.
Time will tell how waterproof it is etc.
One panel is darker, they are all repaired, new old stack panels.
There are seven panels in the picture, two standing against each side of a pair of steps, my spraying frame, lol, in the middle of the lane.

creocoats crap i use genuine creosote with a few cupfulls of waste engine oil in. do the fences every 3 years and the posts are as good as new after 35 years

A 'before' picture.
First coat of three.

Just a quick update.

I ended buying a Wagner sprayer and used with Cuprinol Ducksback (10:1 with water). I masked up the concrete posts and gravel boards. It was simply to use with minimal overspray and went on very well.
Still used 3 coats taking time with first but the second and third were much quicker. The result was a solid deep colour but with the wood grain clearly visible.

Another bonus was the 1.4L capacity so no need to be refilling all the time. It also blows warm air out speeding up the drying. Cleanup is easy too.
Downsides, 1.4L capacity gets a bit heavy after a while and refill time gives your shoulder a rest. The hot air isn’t that welcome on a hot day.

£55 for the sprayer saved a lot of time and we’ll worth it.

 

[Ross365]

Could give us a link to the Wagner; thanks. I guess that it does use a compressor as per OP but is electric?

 

[Craig-SM]

This is what I bought but they also do sprayers that do fencing and interior paints too.

The water based stuff will spray fine with a large enough nozzle. The issue comes when you want to do it again. All the wax comes to the surface and stops the new stuff adhering. I have some proper creosote (about 40 litres of it) but this is too dark really so I use the B&Q 15 litre buckets with a fence coat brush. Scrub it in well and it gets through the wax.

 

[Onoff]

I have some proper creosote (about 40 litres of it)

Mixed 50/50 with old engine oil, can't beat it for fences etc.

However...highly carcinogenic I believe. Chap owned our local wood yard / saw mill had been making fencing panels etc for years and offering to pre coat. Had a huge dipping tank of creosote. He started with facial cancer that took his nose first and just ate away. Story was it was the constant exposure/splashing to the face that got him Still, there's fences he made still up!

This is well before PPE. As kids we were allowed to get sawdust and shavings for our pets. They would turn off the saw and lower us into the pit where the huge blade sat. Unsteady footing next to a razor sharp 6' dia blade. Happy days!
