    What is the difference between airless paint sprayers and HVLP paint
    sprayers.

    I am completely renovating a house and plan to re-texture the ceilings
    and walls with orange peel, prime and paint everything AND refinish
    the oak cabinetry. I was planning to use a Graco Airless unit from
    Home Depot for this.

    Is HVLP the same thing as using my air compressor with a spray gun?

    Should I get both types?


    Thanks,

    Ted

    I am doing the same as you but might be alittle ahead of you. I did
    research on airless vs. HVLP. Some of the best information came from
    the Sherwin Williams store in my area that specializes in commercial
    spraying. They are a regional center for all the Sherwin Williams in
    northern Ohio and Southern Michigan.

    Airless creates more overspray than HVLP. Airless is best for covering
    large areas quickly and is especially suited to new construction. HVLP
    is High Volume Low Pressure. Not the same as just hooking up a sprayer
    to your compressor. A good low end HVLP sprayer will cost about $300
    but will do a great job of finishing woodwork or other fine painting. I
    have used mine in my garage but am told I can use it in my furnished
    house with no problem. I am a little scared to do that. HVLP puts a
    small amount of paint right where you want it. Painting a wall or
    ceiling would be slow work with HVLP. I use mine for doors, cupboards
    vanities and trimwork.

    I use a Wagner Professional Power Roller for walls and ceilings. It
    cost less than $100 at Lowes. I can apply paint right out of the can
    faster than I thought was possible. I never need to stop and load the
    roller so every minute the roller is in my hand I am applying paint.
    Another plus of the power roller is that it is easy to clean. Hope this
    is some help. John

    Airless units are paint pumps and ideal for large volume interior and
    exterior latex jobs. Expect to pay real money for one that will give an
    excellent finish. Considering the amout of product you can put through one
    in a day, consider renting those same good sprayers for your project. I
    wouldn't use anything else for large latex jobs. Cleanups are pretty quick.

    HVLP spray guns can be either turbine or conversion type. The main
    difference from standard air driven spray equipment is the reduced overspray
    (and the lower fumes & product cost). There are a number of decent complete
    setup turbine units for small money out there. Fuji comes to mind, but you
    should look at homesteadfinishing.com for recent info. The conversion HVLP
    guns run off air compressors, best results are with 10+ CFM compressors, but
    some guns seem to do well on less.

    I use an Accuspray turbine gun on a Capspray turbine. I get excellent
    results with slightly thinned oils, clear waterbase poly and lacquers. I
    get 8 psi at the aircap, a 4 stage turbine would probably get 10-12 psi and
    allow it to better atomize the thicker finishes. I don't run latex (and no
    longer run wb poly) due to dried residue missed in cleaning effing up
    lacquer jobs.
