I am not an expert, but that model looks great for what you want to do and more. I picked up a simple Titan 345 that is 7/8hp and 0.021" tip nozzle and have shot a ton of paint with it. I don't know the nozzle size of the one you listed, but the .021" nozzle will shoot 5 gallons of paint in about 20 min. Last time I used it I put 13 gallons of white barn paint up in 2 hours of spraying, my hand hurt and I needed breaks. I have painted 2 exterior buildings, stucco ceilings, and an attic white, about 150 gallons of paint through this unit. The tips wear out and are pricey, $30 each, and the inside of the gun is expensive, $80, after about 100 gallons, but they work great.
Things I learned:
Prep is key. You will spend more time masking and taping off things then painting.
Clean up is important, you can leave the gun wrapped in a damp rag in a bag for up to 16 hours, but you need to clean it for the long term, plan 45 min to clean it.
I had to dilute my exterior paint by adding about 1/2 gallon of water per 5 gallon paint so it would **** better
It takes about a 1/2 gallon of paint to get the hose full and unit primed. Not worth using unless you are painting more then about 2 gallons.
Think of it as spray paint, anything you don't want painted needs to be taped off. Windows, doors, trim, railings, bushes, foundations, grass, soffets, gutters, etc.
Mine did not have wheels, wheels will help.
Get more paint then you think, siding will use more paint, more surface area then flat wood.
Is it primed? Bare wood soaks up paint
About 20% gets lost in the air
At minimum wear a resporator and goggles. I would suggest gloves, hat, long sleeve, long pants, ugly shoes and even a tyvek suit. It gets everywhere
Have cars 100' away if you can
Once you run out of paint, put a 5 gallon bucket of water on the hose, you will get another gallon of shooting as the paint is used up in the hose. Then you will get watery paint, which is a sign to stop
To prime to start, spray the gun into a contractor bag, it will not spray all over while priming the unit.
When cleaning, turn off unit, pull the trigger to release pressure before diassembling (I did not the first time, paint everywhere)
Have two 5 gallon buckets for cleaning, toothbrush, warm water. Just keep cleaning it.
Make sure to oil the unit when you start and after, I just use 3 in 1, but it is probably a bad idea
Have a heavy duty extension cord, they pull upwards of 10amps.
These paint wonderfully, fast, and great finish. Set up, masking and clean up will take 3 x longer then paint. I spent 2 hours setting up, 2.5 hours shooting 17 gallons of paint, then another 1.5 hours cleaning everything and putting things away.
