Old School Roller, New To Spraying

remodeling joe

i've rolled and brushed for 22 yrs and i just bought my first sprayer. it's a graco 190es. i used it on ceilings and works great BUT when i used it on walls, all i saw was lines everywhere. I NEVER LEAVE LINES with a roller. i used 513,515, and 517 tips and still have horizontal lines with even two coats of flat promar 200. i did thin the paint with water as i was told by a hd employee who sounds like he knew something. should i thin the paint?? i did set the psi on various levels and still get the outer lines. the filters were both clean too. someone please help this old school painter with a new trick.
thanks.

well im only 22 years old only been painting for 3 1st yr of my own business.i got the graco xr5 at hd a guy about 50-60 in the paint dept seemed knowledgeable told me it would spray latex got to my job sprayed 2 coats 36 shutters (benmoore lowlusture 100acrylic no thinning) with it an loved it after doing 14 by hand it seemed like i was really in bussiness now, having never used a sprayer before.i cleaned it out filled up with the body color(same paint) made a rig to hook it on my laddder climbed halfway up my 32 footer hooked it and the 5 got to the very top to spray aluminum siding, sprayed a couple passes with ease then the tip blew out sprayed like a super soaker splashed back on me all over my face got in my mouth all over the roof and landscape it was absolutely terrible i kinda just stood there for a minute in awe!now i have a 500 dollar stain sprayer,what a joke. ill never take advice from hd employees ever again! thats all the advice i got for ya, just thought you might get a kick out of it,just when you think you got it bad someone else's got worse.oh yeah did you watch the spanish operators tape!real helpful to me!

hope someone can help you though i plan on buying a bigger spryer soon for exteriors and would like to avoid this problem!

Farrell,

That is E for effort

for real that is cool, I mean I feel for ya.

I know not to try that trick now.

Maybe straining the paint would have helped
ANyway, you are right bout advice from some

Joe, pressure will matter, and maybe your sprayer cant handle 10" patterns or maybe it will. Try cranking the pump up SLOWLY if still, then maybe upgrading will be better.

I too have an XR5

thanks i guess? i was just reading the other thread for this same topic/post however that happened?they mentioned using a whip to support a bigger tip size?what is that?can i use one on my xr5 to spray my benny moore 100% acrylic exterior? newbie!

i used a fresh un-opened gallon when this happened

e for effort are you bustin on me i work solo right now this job consisted of garage:sanded the whole thing practically down to bare bones that clap with the groove on the top PITA to sand,repaired 20ft soffit, full prime color change,caulk,finish coat all cut n roll two colors,approw250sqft

house:approx 2500sqft 3 storie painted aluminum siding and eves, power washed entire house on ladders no wand,stripped, caulked, prime, paint 18 windows,36 shutters, huge front porch,preped railings, prime paint, caulk, stripped the entire floor, close to 100ft accented crown 2 coats other random accents etc... hung the new shutters did touch up rounds every thing was perfect in under a month flyin solo.you can see why i broke down and got the sprayer.on the plus side i landed around 8k in contracts, mostly people stopping to ask me why i was working alone at 9pm on a sat. yeah i had the floods out!

I'd school ya on pressure and diameter but, it's alll over the net. Bascially a whip is a 2 foot hose extension with a slightly smaller diameter with a cool swivel. Ya it makes LOADS of difference. Sorta like holding your finger over a hose will shoot the water farther.

Under pressure... ding ding dingdingding ding

hey farrell, man; that's got to be the funniest story i've heard about work incidents! lmao!!!!!!!!!!!!!!!!!!!! lol!!!!!!!!!!!!!! thanks dude!!

Just takes pratice but also play with presure

A whip will not help with pressure, I was told it decreases pressure due to the smaller hose. It is used so the line does not get all tangled up with kinks. It makes all the dif in the world. Try a Titan 440i- it is a good all around sprayer. Or, if you plan to spray more in the future, save your $$ and get a SpeeFlo- it is the best rig your dough can buy. Also when you sprayed all over yourself- It sounded like your tip was in backwards or not in all the way

the lines in the paint could be from two things. If you spray those walls at an angle instead of straight on you will build heavier at the near edge. If you have a wider tip (sprays a wider pattern) than your rig can handle (not enough pressure) you will get a line at each edge of the spray pattern. If this is the case, get a narrower tip. You may need to give the sprayer a second between swaths to catch up.

Double coat by putting the center of the spray pattern over the previous edge.

That spray/splatter was probably because the reverse-a-tip was not in the correct position. If it is turned to the side so paint can't spray through it, you will get that pressure splatter everywhere.

Spraying works well, saves time. Just don't try to save more time than the sprayer will allow.

I prime and finish a 2000 square foot house in a day by myself. This is new construction, trim not yet installed.

thanks for the info and suggestions,when it happened i was spraying then it just spit,after i cleaned up the mess i uncloged it replaced tip in the spray posistion and all it would do was spit trust me!it wouldnt spray no matter what i did!so either the tip blew out cause the orfice is to small for acrylic or the pumpis just to small?????? i guess ill just use it for oil and stain.

does anyone know any way to get this rig to spray acrylic dependably?

i hope to get into new construction!

Workaholic

call it a defective tip, that would be my story anyways.

Ahh, but it does. No, it will not increase pressure or etc. A whip is designed to keep the pressure rated on the machine constant, certainly if you add more hose. If it's rated for a .019 and you add 100 feet of hose, you can't still use the .019 tip... so ya, the whip was designed to help with pressure. Next time your out buy one of those HUGE extensions, they are like 1 inch round.. hook it up and try to blow ceilings... then take it off and go back to your 1/8 inch 2 footer.

how does adding more hose effect pressure in the rig?i could see how if you add a 1" dia it wouldnt spray the same as the stock(smaller dia) cause your pumping more paint into the gun(i think),should be the same psi though right?why cant you run the max tip if you add hose length?so cutting down my stock hose will allow me to run a bigger tip?i dont have any exp w/sprayers and im not sayin that your wrong but im struggling to understand your reasoning.maybe you can use multiple gun rig as an example!ive never used one i do know that max tip size decreases as you add guns,but ?? is it just the extra hose length,or is there like psi regs for each line?how exactly do they work?
thanks!

Longer hose means the pump is pushing more paint through the hose. It takes energy to push the paint and that lowers the psi. Also there is some drop in pressure when pumping up such as when you are on a ladder.

Multiple gun rigs you need to add all the tip sizes together to get the total tip size. This is over simplified but the idea is correct.

As far as the lines are concerned If you are talking about lines I have heard them called tails and they form at the outer edge of the spray pattern. Two things cause these either the pressure is to low or the tip is worn. Go to a 5/15 tip and gradually increase the pressure until the lines disappear. Your machine should push latex paint without thinning if not thin as little as you can get by with.

I don't really understand your problem but I can not see how a sprayer being too small can cause a tip to blow out. If the tip plugs then it would just stop the paint flow. A plug is much more likely caused by chunks in the paint then by the paint being too thick. A bigger sprayer will plug also if a chunk gets to the tip. Do you have a filter in your gun? What do yoou mean by the tip blew out? did it litteraly get blown out of the gun?

the tip .015 was to small for 100% acrylic so it fauled,i tried everything and it just wouldnt spray it just kept on squirting!or the tip was defective??????????????who knows????? last time i spray acrylic with it ill tell ya that!

as for increasing hose length that lowers psi that lowers max tip size i dont understand that,from what i understand gpm is the only variable that has to do with using different tip sizes!a multi gun rig runs the same psi with 1 or 3 guns hooked up right?when your running 3 guns you can only use the lowest tip size recommended for each gun cause the pump can only supply enough material to all three guns/hoses if running to big of a tip or you will get tails, but the lines should have the same/enough psi 1 gun or 3,that said if you wanted to run the total length of hose for the three guns on one gun you could only properly run the lowest tip reccomended when running all three guns????for example my xr5 has the same max psi as the 190es but the 190es can support a bigger tip size cause is has a higher gpm rate.

or do multi gun rig have a psi regulator for each outlet??

i ask all of this cause im lookin to buy a new rig this season,but i dont want to make the same mistake of just buying one that someone suggest(thanks though)i want to understand what and why im buying it!
thanks!

Brushslingers

Ummm, .015 is plenty big enough for latex. Correct question for Jim to ask though...... what exactly do you mean by the tip blew out? I mean you keep saying the tip squirts all over, tip blew out, tip isn't big enough...... explain a little more?

The whip is used to make the hose easier to handle, and it also cuts down on the volume of material being pumped. Lines with the tip are called "fingering" usually comes with either a dirty tip or not enought pressure with the airless, maybe even to much hose and/or to big a tip for your sprayer.

farrellpainting

i think ive i covered all aspects of MY xr5 .015 for 100% acrylic issue!the manual says .015 isnt enough to spray acrylic,and the xr5 cant support a big enough tip required/recommended to shoot acrylic,it does say that it can spray 100% latex,but acrylic resin is too thick??? or i just got a faulty tip???does anyone spray 100% acrylic through an xr5 with .015 orfice???as you can see i dont know @#$% about sprayer physics!and as ive said before i cleaned/unclogged every thing after the mishap,i used a fresh gal(no skins),installed the tip in proper position,pulled trigger many times, and it still pissed,im goin with workaholic's theory that it's a defective tip,it the only thing that makes sense to me.but either way im not going to use this rig to spray 100% acylo, unless someone that uses/used the xr5 to shoot 100% acylo can convince me otherwise.

i keep getting all of these answers like it does this or it does that but no reasoning/explanation to help me understand why?how does a whip cut down on material being pumped?cause it extends the hose length?

anyway can you help me out with some sprayer physics,the q's i asked about hose length,and do multi gun rigs have independant psi regulators for each line,and whatever idiotic q's ive asked about sprayers?thanks
