Hello-

Looking for a bit of guidance as it seems as though there are a few of you here with experience with the capspray units. I just picked up a gently used Capspray 9100 (4 stage) with the Maxim II gun. It's been a great unit so far, but I am working on some cabinets and could use some help on a tip size for the finish coats.

I sprayed the primer (very slightly thinned with water) with a #3 tip and had great results. I do have a #5 tip that I plan on shooting the Acrylic Latex with. Any guidance on whether this is a good choice and should I use floetrol or a similar product? I will be spraying the SW ProClassic.

Thanks-

What was your primer? It sounds like you're on the right track. I would start by adding 2 ounces water to your mostly filled quart cup and stir. Test on a big scrap of paper, I typically tape a piece of floor paper on the wall. Open your air all the way, and gradually open up your fluid nozzle until you like what you see, and have the flow and width you want. You may end up adding a little more water (3 ounces would be thinning 10%) but see how the 2 ounces goes first.
If you have to tip the gun upside down don't fill it up quite as much. You can also add an ounce of XIM extender, which I think is better than floetrol, but try without it first.

Damon-

I used the SW Multi-Purpose Zero VOC primer. Went on nice with the #3 and a few oz of water. I'm hoping I didn't go too big with the #5 tip for the finish coat. I've got a nice test set up that I'll spray first. Shooting this afternoon. I'll post an update later.

Yeah I think someone posted that chart on here somewhere. The Titan rep came out to my job site to help with the transfer pump, and said the #5 was suggested for acrylics typically. I do have a friend with the 4 stage who only uses the #3 with everything, and just thins accordingly, but I'm not suggesting that. Experimenting is the key.

I hate those beastly machines. I have had a 4 stage graco for years and it has never worked right. Tried to do some doors last week with it using acrylic undercoat. Same old story. It doesn't seem to atomise properly. Like a speckled finish. I give up with it. It,s heading for ebay

What size needle setup? What % did you thin? What product?

It was an acrylic undercoat, size 4 needle and have tried thinning in various ammounts over the years(from 5 % to 20%). Never seems to atomise properly

Not sure how the Graco sizes compare to Titan. I think my #3 is .051, #4 is .072", and #5 is .086. I could be wrong. Anyways. Have you tried the larger setup? My understanding is that with acrylics you need more air at the tip to atomize the products, and the larger needle and aircap will give you more air. Actually a larger needle will give you more material, and a larger aircap will give you more air to atomize the product. You can use a smaller needle and larger aircap. I have had success with my turbine set on 4 stage, though I typically will run at at 6 stage. I typically run the #5 setup when using acrylics.
