Gentlemen,

10 interior doors to paint and here is what I need to spray:

-Sherwin Williams Super Paint Interior Acrylic Latex

-Airless Pressure- 2000 psi Tip – .017”-.021”

-Have to spray outside due to small crowded garage

That seems like a pretty big tip size, no? But the paint is very thick I guess. I normally use
my trusty old 4 stage Capspray HVLP for finishing but it can’t handle material this thick.
So, should I buy for example a Graco X5 or X7 (apparently the X7 can handle a .017) or
buy a larger compressor and spec out a gun? Seems like anything under $300 won’t be
able to handle this paint’s viscosity. I don’t mind spending money on tools that will last
and be useful. In the future I will probably go with a different paint ( or avoid latex all
together) but for now I need a setup that can deliver a nice smooth finish with SW’s Superpaint.

Also, I would like to be able to paint occasional pieces of furniture with this setup as well.
Does anyone have any advice on what is the best solution? All I know for sure is my HVLP
can’t deliver on this job and I am tired of reading about all the different “POSSIBLE” solutions.

Thanks !!!!

TJ

Home depot rents medium duty and heavy duty airless spray equipment (mostly Graco), both designed to spray directly from 5 gal buckets of latex paint. If not needed very often, can be more economical solution than buying one.

Easy to find here in AZ, rough stucco exteriors forces spraying all house exteriors, so most HD have 2-4 rental units available. :) Even my local SW supplier has 5 gallon sized HD airless rentals available.

YMMV

The Graco X5 will spray the paint just fine.

with an airless sprayer painting door is quick. basically its a one pass and your done, two passes and you will have runs. Tip size looks right, airless sprays are meant to shoot a large volume of paint.

If you suspend your door so you can paint all the edges it make life easier. I drive two 3” -4” deck screws into the bottom of the door to keep it off the ground. I also put two more in the top used to keep the door upright. The two screws on the top I have rest against a board attached to a ladder. Another option is to put a hook or two in the top and suspend the door.

Spraying the door, all sides will take a minute or two at most. Moving the door to paint the next one will take longer. Your best bet is to figure out how you either paint all the doors without moving them or figure out how you can move a freshly painted door to a drying area so you can paint the next. This will save on having to clean the airless sprayer. Cleaning the airless is the only downside of using an airless.

Might want to consider a handheld graco unit. you will have to refill the cup each door but it’s less cleanup them one that siphons from a bucket. Also you will likely go thought more paint than you think. There will be more overspray than you think. 10 doors I will guess you will use a gallon or a bit more.

I have repainted 30+ doors at a time. A helper is really nice for moving doors, especially if they are solid core doors.

If you are only going to a door or two a time got handhelp sprayer. They are a little bulky, but the easier cleanup will be worth it. The one with the collapsible paint cups is nice if you are paint at extreme angles put they can’t be reused, I prefer to put on a flexible tip extension to not have to deal with holding the gun at odd angles or getting in to tighter areas. Not really needed for doing doors but if you are looking at other projects might be helpful

I swore off latex. I find it much easier to spray lacquer and I like the results better. Sher-Wood CAB acrylic lacquer is available in any of their colors and multiple sheens. It flows out beautifully and dries fast.

I wish I had thought of alternatives but latex is my uneducated default choice for trim and doors.

Bill, which handheld Graco are you talking about? They have a few models from cheap to expensive with varying reviews.

I suppose I could always use a roller and save the money, not time, if CAB acrylics are better and will work with my HVLP nicely. I hate Latex as well, just have never explored the alternatives. That would sux if I bought a paint sprayer and then discover an alternative that made my new paint sprayer a dust collector.

Home depot rents a sprayer for $85 a day…....I’m going to need it longer than that, so thats not feasible.
