Spray Finishing Part 2 Tips & Tricks
HTML-код
- Опубликовано: 8 сен 2024
- A continuation from Part 1...with more tips and added information on the basics of spray finishing. If you're new or intermediate...maybe even a pro, this video has something for everyone.
Note: Not in video but an afterthought; If the spray pattern seems different or sluggish, and you've already tried my "rag over the nozzle" air brush trick...try this. Spray some thinner (water or solvent, or feel free to waste your finish ;-) through the gun whilst turning the adjustment knobs...the spray pattern, the fluid volume, and even the air pressure. Sometimes this will clear any small obstruction. If not, a thorough cleaning will always do the trick. Find that video here:

Ramon, It is obvious you know what you are doing and you present it well.......Thanks so much for sharing this valuable information.
Thanks! I sincerely appreciate the positive feedback!
Always great explanations Ramon. I have been falling back in love with the finishing process as I love having control and never loosing practice by doing small projects. Truly considering getting an airless but as right now, my bottom feed quart HVLP Fuji and Apolo guns. Love the teaching techniques.
Thanks! Spraying finishes is a blast for me as well. I use to use an airless a ton for spraying large jobs…cabinets and cabinet doors. Those are a difference animal…gotta move quickly! 😬
@@ramonartful exactly. I have a great finisher for the large projects 🤷🏻♂️ technically he and his crew are my spray less crew 😜
I just upgraded my shop with a air assisted Kremlin sprayer and I'll tell you it's the best system I've ever used for spraying lacquer.
Appreciate your knowledge/tips. Great information...thanks Ramon!
I really appreciate the feedback…thanks for watching!
Great material content. I was gonna ask you about the HVLP gun you used in part I, but as usual, with all the professionalism of your videos, my question was answered!
Thanks a lot for sharing such a valuable information.
Great job, Ramon!
Thank you for your positive feedback! I appreciate it.
Always figured you needed a booth and large fans and stuff an I agree whit yeah on being able tot do thing's with both hands I can do most things although I am note really good whit striking tools in my left
Fans do help for sure. But I can get high quality finishes outside, not my first choice but if the project is large, it works. And yeah, being ambi is such a huge advantage!
Excellent tips in this video, Ramon. I need to do more using my left hand since there are times when it makes sense to use that hand - practice makes perfect. I also need to start using scotch brite on the edges so I don't burn through. Have you tried rubbing with a brown paper bag to remove dust nibs? I've used it in the past with success and have seen Phil use it as well. We talked about the 3M PPS system at AWFS One advantage that I forgot to mention is they have a built in strainer in the lid so 95% of the time, I don't have to use strain the finish when I pour it in. Thanks for all of the time you put into these videos!!
So good to hear, David!
I have used brown paper…it works… okay. I’m not sure why I’m not a fan.
The PPS system looks good, I will look into that more. I’ve had a few people recommend it.
Thank you for watching the videos…I certainly appreciate it!
Great stuff Ramon - it helped me feel better about some of what I do when I spray and taught me some great stuff. The Wood whisperer just started selling double sided paper!
Last thing - what is the difference between the top and bottom feed sprayers?
Great to hear! Siphon feed (bottom) are kinda old school but work well. Gravity feed (top) are now more popular. I’m not sure of major differences other than a siphon feed may require more air since it has to draw the material out versus a top mount gravity type. I’ve used both and don’t really have a preference. I currently have two of each. Well, as far as siphon feed, one is an HVLP system (with its own turbine, no air compressor required) but that’s another topic. Which BTW is a good choice if one doesn’t have a large air comp. Spray guns that use air need big air comps. Hope that helps. Feel free to ask more questions
@@ramonartful lots of help! I have a Fuji semi pro2, so it’s a nice system but I see more like your gravity feed now
Finally got around to watching part 2. And again great suggestions. Could you please elaborate on what you use at the 3:50 min. mark to tone the finish? Is it toner, dye or paint? If toner, what brand? can you tell us more on how you use it? A video just on that would be very helpful. Years ago I bought some dye in small bottles (at Woodcraft), not sure the name. They look different than then transtint dye bottle at 13:30, but the name sounds familiar. is it best to tint the stain or the finish? I had little success and wasted lots of it trying to get things right. I agree the lighting makes a huge difference.
Sure. It’s called a colorant…that I got from Sherwinn Williams. They use it to tint latex paint and stains. It’s unique formula allows it to mix with water based, oil based and alcohol based materials! I got primary colors from them knowing that I could then make all other colors. A color wheel is extremely valuable and I regret not mentioning or showing one of those in the video. They’re inexpensive and can be found on Amazon. With a color wheel you learn what primary colors make secondary colors, mixing those to make tertiary colors and so forth.
I typically stain with something close…if I can tint the stain and get closer, I’ll do that. Then I use the seal coat as a toner to dial in the color. This coat is just a mist…or it can muddy the look easily. It’s an art as well as science. The last coat or finish coat locks everything in. I’ve only done this when spraying solvent based lacquer. And I really don’t do projects anymore involving stain. It’s not my favorite! Even though at one time I could match anything that came through the door!
The colorant is Accurate Dispersions brand. It’s called Maxitoner industrial colorant. I use Phthalo Blue, Red Oxide, (not really primary color) Medium yellow, and Lamp black. Hope this helps.
@@ramonartful Yes that helps a lot. I will check them out. Thank you so much.
inspired to try out spray finishing after seeing your videos. Still looking at all the options for guns, which needle size do you use? I have seen some difference of opinion on that matter. thank you for all you do!
It can get confusing…but in general…smaller for thin materials (like clear coats) and larger for thicker, like primers. So the range is generally going to be between 1.2 to about 2 mm. So, a 1.5 mm is a good place to start. Just remember the trade offs. Like wide patterns will need a bit more pressure than narrow patterns. Use just enough thinner to make your gun atomize the material. If it’s spitting or looks speckled as it lands, it could be too thick of material, thin slightly. If it’s too thin and watery, then you won’t have enough “build” and it can run too easily on vertical surfaces. And use lower pressure rather than high. This will reduce overspray. You need just enough pressure to atomize the material properly. Practice on cardboard. Have fun! Much thanks.
Thanks for the detailed response Ramon!
Have you tried the 3M PPS system with your gun? Easy clean up
I haven’t. Someone else on Instagram commented to my post about this. I’ll check it out. Thanks!
Great video. What air pressure do you normally run with your spray guns?
Thanks! The larger DeVilbiss gun requires at least a 3/8” inside diameter hose (not 1/4”) and the pressure (as the trigger is pulled) is 23 psi. The smaller gun…I just guess. It’s probably running around 15 - 20.
Thanks.
Ramon, how does the wet film thickness of your coats compare with that which the finish manufacturer recommends?
I believe they’re pretty close…why do you ask?
Any chance you will have plans for some of your pieces?
There is a chance. I would like to build some simpler pieces and have plans for them. So much to do always! 😆 thanks
Does it get too hot that x’ your wife ask you to become her perso Al water mister? 🤓😜
