I finally got to finishing the 100 metres of intricately ornate school railings this week.
Spent a day repriming with zinc phosphate as a final coat before the protective finishing coats.
Then I decided to purchase a solvent specific airless spray gun for the task, to save myself maximum time....and it has proved to be the best £200 I've ever spent!
Finding Earlex to be the reasonably priced manufacturer of this kind of equipment, I phoned their technical advice number and was advised to go for the HVLP 5500 model to spray oil based paint (in my case - gloss).
Not only is it lightweight, portable, easy to use, super precise, relatively quiet, and with mimimum overspray.....it also halved my time to cover the fence! Earlex advertise this spray station as "semi professional" and I used it non stop for 2 days in a row, It was more than up to the task, already paying for itself in the process. I will now be using it to topcoat a load of prepared woodwork in a private house this next week!
Spray gun advice to follow.....!
