n00b with questions about Sprayers, Prep, Applications


Hey guys, I am a new home owner and I am looking to repaint my entire house exterior. At first I was leaning towards subcontracting the project out but my grandfather has also just purchased a new home in the same city that will need to be repainted as well. I figure the amount of $ to be saved by purchasing a quality unit and doing the job myself would be worth the cost of the unit and of course my time.

Ive been restoring cars and motorcycles for years and I am very comfortable with painting because I have been painting cars and airbrushing/pinstriping for quite some time, so I figure taking on a house will be no more difficult than painting a car.

At this point I have done some reading and researching around the internet on sprayers and have read some good things about the Graco Ultra 395, Titan 440i, Spraytech 2105, etc.

I have also looked @ craiglist and found a few sprayers local but I get a little worried when I see a 3k+ sprayer being sold for 600-800 dollars.

Do any of you fellows have some advise on a quality sprayer?? It sounds to me that I will need 2 different sprayers if I wanted to paint outside/inside...

If that is the case any advise would be great for both inside and outside units. Can I use the Graco 395 on the inside as well??

Can I use the same unit for primer and color coat??

I will probably make another thread regarding the painting process because I have some questions about that as well but I do not want to overload the thread.

Thanks guys!

I know around here use sprayers are tuff to get rid of, so if they are the same in your area, then the price would seem right. If you are really worried about it, you can have the people set it up with water to see if it works. I always recommend priming with a brush or roller inside or out. You really ned to work the material into the surface for better penetration. I know people will tel you they have sprayed primer on bare drywall or wood countless times with no problems, but I have seen bad paint jobs that can be blamed on the paint not penetrating and your paintjob only needs to fail once.

Spraying on anything will work. There is no such thing as the need to work it in. Think about it. Furniture and cabinets have the finest finish and toughest. And its on wood. And every step is sprayed. An airless sprayer will be used for medium to large jobs outside or new work inside. Smaller jobs it is not worth it, since cleanup will take longer than the job. You need an HVLP with turbine sprayer if you want to do smaller jobs like trim and doors with oil or to paint with epoxies and urethane. these you may never find used for sale, since we rarely use them, but will never give them up either. I had one that I still use for almost 20 years now. Cabinets and such are sprayed with a cup gun and large compressor (still a HVLP gun) the same way you sprayed cars. The airless can also have a power roller attachment. To see if this sprayer is in good condition, see what tips they have, what cleaner and or lubricant they use and where it is stored. Many people leave them in the garage and the pump is shot from freezing which cracks the ceramic pistons in the pump.

You are comparing apples to oranges. Different materials and larger amounts of surface area. Plus you will be using a ladder. Not saying you cannot do it, but don't think it will so easy.

At this point I have done some reading and researching around the internet on sprayers and have read some good things about the Graco Ultra 395, Titan 440i, Spraytech 2105, etc.

I have also looked @ craiglist and found a few sprayers local but I get a little worried when I see a 3k+ sprayer being sold for 600-800 dollars.

Desparate times make people desparate to make a buck You may be able to get a great deal.

Do any of you fellows have some advise on a quality sprayer?? It sounds to me that I will need 2 different sprayers if I wanted to paint outside/inside...

The Graco or the Titan will do what you want.

If that is the case any advise would be great for both inside and outside units. Can I use the Graco 395 on the inside as well??

Can I use the same unit for primer and color coat??

Yes. Clean between paint changes.

I will probably make another thread regarding the painting process because I have some questions about that as well but I do not want to overload the thread.

Thanks guys!

n00b with questions about Sprayers, Prep, Applications


Thanks for the info guys. And thanks Bikerboy for the direct answers

My compressor will come in handy for the trim projects and what not that I have around the interior of the house then. I figured that it would be that way. Im glad this expensive compressor I bought will come in for even more than my auto and moto work.

SO priming the outside of the house is a must. I hear ya. I did some more reading and it looks like back rolling is the main move for painting anything like stucco. Do you need to backroll the primer??? I also heard I need to clean the outside of the house down before paint starts.

I have a pressure washer that I can use to clean the outside of the house off. Some say soap it down/

I found a Graco Ultra 395 for 400 bucks on CL its pretty new. Im going to look @ it.

Priming the exterion is not a must IF the paint is in good condition. Proper prep IS a must. Go to the big names the pro's use. PPG, Benjamin Moore or Sherwin Williams. All three have paints that are self priming, and will go over older oil based paints. You will pay more per gallon, but you save by doing the exterior less often and not having to purchase a separate primer.

I have sprayed a lot and the only reason to even roll after is for
A .block.pores have to be filles
B.expect a lot of touch-ups due to other trades .its a bit easier to blend in a rolled wall than a sprayed wall

n00b with questions about Sprayers, Prep, Applications


I have a Graco 395 sitting in my living room as I have just finished painting my entire inside of my house. They are very easy to use and will give a great paint job. Most important thing is to make sure it is cleaned out with appropriate cleaners as per paint type and then use a product to clean and protect the lines and pump etc. I use liquid shield plus as it is also an antifreeze for storage. This product also prevents corrosion of parts.

Hope I have helped.
cheers

I told ya so..... Bob making a comparison to furniture finishing is quite a bit different. Wood will typically accept the stain / poly better than drywall. It will be properly prepped by sanding cleaning and sealing. I was mainly referring to primer application which on new of freshly patched drywall can have surface dust.
