The size tip you use depends on what you are spraying, how thin/thick it is and if you something like Flotrol to make it flow on the work better. Tip sizes are given as a decimal number and here's how to read them.
Example: .517 (the one most people, including you, need)
- The 5 means you'll get a ten inch swath of paint with the tip 12 inches from the work surface. 5's are for general painting, 2's and 3's are usually used for trim work.
- The 17 is the diameter of the orifice (.017) the paint passes through to get properly atomized. The larger the orifice, the thicker the medium you can effectively spray. .013's are used for very thin things like stain. .015's & .017's are for latex paints, .019's are for enamils, and .021 - .027 are reserved for thicker things like elastomerics.
Most likely if you are using an interior, latex paint, you'll need the .517 tip. Be sure to strain your paint so you'll get an even fan of paint and the best results. Even brand new paint has sand impurities in it that will effect the tips performance or plug up the filters.

SOURCE: new to spray painting and am spraying baked enamel paint

To fix this problem you need to turn up the pressure both at the wall(coming from the air compressor) and at the gun. I would suggest 10 more psi at the wall and 5 at the guns but you can play areound to find whats best for you.

My spray gun keeps stopping and then I reverse tip and it works then stops then I reverse tip and leaking


It's probably the paint-I had a problem with certain brands. I started putting a cheesecloth type filter around the uptake to help filter larger particles and it works a lot better.

Paint gun not shooting correctly


Seeing how you have really stated what the problem is (spitting, clogged, won't shut off, fan pattern wont adjust Etc) and there could be several different things wrong- lets go over some basic spraying A B C'S- always strain the paint through a strainer bag or cone this will remove any debri that might clog the tip, *THINNING when you spray or atomize paint it should always be thinned it will actually cover much better if you thin it with the appropriate solvent water for latex thinner for oil base you want to stay in the 15% range alittle bit more on hot days. The shape of the spray that comes out of the tip is called "fan pattern" or "tip fan" "fan size" you can adjust the fan pattern from 9:00 - 3::00 or sideways to straight up and down or to a small circle this is done by moving the "tip housing retainer" keep a piece of cardboard to practice and see. IMPORTANT:When you have finished spraying you need to clean the entire gun by running the right solvent through the gun untill nothing but clean solvent is coming out dissemble the gun remove and clean needle and needle housing this is not very complicated and is paramount to maintaining any spray equipment for sure the gun....

My graco xr5 sprays when i turn tip to spray position


If paint comes out of the spray gun after you release the handle, your problem is inside the gun. If the needle tip or seat are damaged or the spring that holds them closed is broken, paint will be able to get past the the needle and will come out of the gun even when the handle isn't held open. The stock spray gun that comes with the the XR5 doesn't have any servicable parts inside it so if it isn't working properly it may be garbage fodder. If you have an aftermarket gun, rebuild kits may be available.

What is the correct concistancy the paint needs to be mixed at for the dynatec psg 45 electric spray gun


It depends on 3 things.
What you are painting.
Whether you are applying latex, oil-base, or primer.
What size TIP you are using.
We use spray equipment and use size 17 and 19 for latex, and 11 for oil.
Double-check the size that came with your gun and look at tips at Home Depot.
Old tips wallow out and the spray pattern is irregular/uneven and the gun blows out too much paint and our material costs go up.

The manual says "dilute correspondingly"
http://www.airless.com.au/Airless%20Sprayer.pdf
Let's say you are spraying oil-base stain: I would NOT dillute this material.
Oil-base primer: 1 thinner to 4 paint
Latex primer: use a roller and brush so you have a good undercoat for the paint.
Oil-base paint: I would add 1/8 thinner with 1 paint, and be careful of runs
Latex stain: try 1 water to 4 stain
Cheap interior flat latex: 1 water to 4 paint
Latex semi-gloss interior: 1-1/8 to 4 paint and apply very thin coats and let dry between coats.
Cheap exterior flat latex: 1+ to 4 paint, and add more or less water as needed
Good exterior latex paint: use a roller and brush because the purpose of latex exterior pain is to apply heavy protective coat over outdoor materials ... dilluted exterior latex will not give sun and mildew protection.
We use heavy spray equipment and apply exterior latex straight form the can. It's the only way to give lasting job, unless you're doing a temporary playhouse.

The key to successful spraying is to strain your paint to get out the lump and clogs - BEFORE putting paint into the gun.
We always strain the paint unless it's a freshly opened can.
If can was opened yesterday, we strain it.
That because paint gets a dry film that will clog the sprayer.

First you need to mix your material, so you need a couple buckets.
Pour the paint and thinning material in 1 bucket, and then to mix, pour back and forth between two or three buckets. This action will mix the paint thoroughly and save you an hour of rotating a paint stir stick.
Next, you need to strain the paint.
Wash out a 5-gallon bucket.
Buy 5 gallon strainer that fits into bucket.
Pour material into bucket with strainer, lift strainer up and then grab end of strainer and squeeze out all the paint.
Immediately put lid over paint so no drying film will form.
Wash out strainer.
You're ready to put paint in spray gun.

My graco nova 390 spray painting machine keepa squirting when I stop spraying what could be going wrong


Usually, the fluid valve has a lump of paint or debris caught where valve needle and seat meet. Be sure to strain the paint during fill-up each time. It should be cleanable by spraying some thinner (for the paint you are spraying) and jiggling the spray control. If not, you will have to dismantle the tip and inspect the parts. Hope this helps!

Spraying troubles


Off hand I would say that you have the wrong spray tip for the paint that you are spraying or that the tip is worn. Another thing that it could be is the little piece of rubber behind the tip is worn or missing. My first suggestion is check the tip size with the recomendations of the paint that you are spraying (You will find this on any specification sheet from the paint manufacturer.. If the size is correct replace the tip. A new gasket comes with a new tip. Hope this helps.
