Spray Painting Shed Roofs

reilig

Got a few quotes for spray painting some shed roofs - handy A rooofs which can be done without a slateing ladder. Some of the undesirables were very cheap, but genuine guys are quite expensive. Has anyone done it themselves? I have spray painted a few DIY welding projects in they past but it was pretty basic - 10 minute jobs.

First off I have to buy a new spray gun. I have a small compressor. Would people recommend a gravity flow gun or a suction gun? Will either of these be ok with oxide paint?

Do you need to thin your paint to get it to go on properly? What ratio? What are you thinning with? While spirit? Diesel?

Anyone got any tips or advice or recommend a brand or type of paint?

Thanks

hire the large gun from a local hire centre (fits on to bucket). you will be constantly filling the pot guns otherwise. i'll pm a no. of a lad from down your way who started spraying a year or so back. specializes more so in houses but may do it. i wouldnt thin with diesel. you would be ok to use gun grade thinners for thinning imo and would work out as cheap anyway. i sometimes buy paint of pat mcdonnell in westmeath if you call and ask for technical they should be able to advise you.

Don't thin with diesel unless you want it tacky :eek:

Use white spirit - can be got very reasonable in Lidl or Aldi at times.

Look up airless sprayers reilig, they're what's used, pretty much like pressure washing paint, able to put on thicker paint, so less coats needed compared to a normal spray gun.

Need to be used with care, they have the pressure to put paint straight through the skin.

we have used them in the past, but they are not available to hire locally now because of insurance issues


the wexford (connors) boys do any painting jobs we have these days ,may not be every body's choice but we have good working relationship

Have used "Castle" brand paint on shed roofs, its good stuff IMO. They recommend using very little thinners, 10% or so, and this wont allow you put it through a normal spray gun. If you have the shed roof well washed, and bone dry, you can put it on with a soft sweeping brush. Best method that I have used is to heat the paint to make it runnier.Used a space heater in a small little store room, and had the 20 litre drums arranged in a "V" in front of it. Not an easy job, and messy, but a much better coating than thinning by 25% or so. You also need th have no rain for at least the whole day! Iver in Cavan

ring castle paints, tell them area your covering, they'll tell u amount of paint needed n deliver. 80 +vat for a 20l oxide, if i remember right. theres cheaper out there but i bought cheap crap once n never again. thin with thinners, they flog that too. a 50l compressor is too slow, hire a 100 litre n get a good long hose. get the cup - less refilling. genfitt flog a basic gun for about 20 n there grand.

Hi Reilig

I did a lot of this lately for a relation, with a paint sprayer I bought in Connachet Gold in Co Sligo. The most fantastic tool I have ever owned. I thinned the paint with white spirit (not a huge amount - i followed the instructions. I think it was 1 part spirit to 10 parts oxide, but it had a disproportionate effect on the fluidity & 'sprayability' (if thats a word) of it.

I put in huge days, dawn to dusk, because you do need to do a good bit of dismantling & washing at the end of the day, so the thing stays working - not hard to use, or clean, just need to be methodical.

I did thousands of euros worth of work with it over a long weekend, and having done it with the brush in my youth, it was a pleasure.

I will have a look at the brand & model later in case you are interested. I wish I found out about it years ago!

I did it with the sweeping brush too, in the past. superficially easier, but slow and messy and very wasteful of paint. Tends to be the last shift for the oul brush too.

Cheers,

I'd be interested in that brand and model.
