What’s the most important factor in determining whether or not a paint job will run? I used paint pens that I got from a hobbies & crafts store because they said water-based. I’ve heard people say Zigs are good but the pens I saw were oil-based and I’ve read that oil-based paints aren’t compatible with resins. Should I just let the water-based paint dry for a couple days and hope for the best? Oh, I put the art on the hot coat, waiting for gloss coat, if that helps.
Spray a fine coat of thinners based acrylic clear (I.e - automotive laquer) over the top of your artwork and give that the slightest rub with 1200 wet & dry… This should prevent any issues with paint & resin. Josh http://www.speedneedle.com.au
speedneedle, is that water base acrilic clear or some other ? I to have had problems with my spray jobs -water base- I do the glass job and the paint runs into the resin,paint quality ? -not all my jobs have done this, my last orange paint job ran with the resin,bottom lam looked like a nightmare,top lam better but most of the orange turned yellow, the board is a keeper but I HAVE TO SAVE THE MOMENT FOR THE ART ! thanks to all
The best way I’ve found to check if the paint is going to work, is to keep a test piece of foam nearby. If you want to spray on the foam of your board, spray it first on the test piece, then laminate it to see what happens. If you want to try something on the hot coat, laminate and hotcoat the test piece, then do your experiments on that. It may seem like time consuming extra work, when you’re chomping at the bit to keep going on your board, but it will help you take the guess work and the cuss out of the project that really counts. And you’ll learn alot with that test piece. Then you keep it for reference or just toss it. Doug
Howzit Greene, sounds like you’re thinning the paint with too much water. Too much water depletes the acrylic content of the paint and it doesn’t adhere to the foam very good. I use 1/2 water and 1/2 acrylic thinner to keep the paint from bleeding. Aloha, Kokua
Kokua, Do you spray this 1/2 water, 1/2 acrylic thinner before or after painting the blank? Also, what is the ratio that you use to thin your paint, and what do you use water or the thinner?
mix the paint with 1/2 water, 1/2 acrylic thinner…the acrylic thinner will help it dry better in between coats. the most important things to do are: let it dry completely between coats,don’t spray on heavy paint. after the blank is painted and dry you can spray it with a clear acrylic. it’s not necessary, but helps to seal the paint up…good luck
Howzit Phil, The 1/2 water 1/2 acrylic thinner is what you thin the paint with.Aloha,Kokua
So I can gloss coat after I spray with clear acrylic and it shouldn’t give me problems? I’m not airbrushing, I’m using paint pens. I’m not sure if they use acrylic paint but they are water based.
Hi, sorry for the delay in my response…The original answer to your question stressed again for clarity - It’s petroleum (Thinners here in Aust.) based acrylic I speak of, not water based, to seal your work before gloss coating over. A fine coat. If you use thinners based paint for your artwork, you can gloss straight over it, but a fine coat of laquer is best for inexperienced glossers… http://www.speedneedle.com.au
Thanks for the tip, can I pick this stuff up at any hardware store or is it a specialty item?
I have painted numerous boards with pens, especially those old favorites that have been repaired or need a face lift. I received initial help from an artist at …lost when I watched him paint my board and have found the process very easy. I use Poska (spelling ?) or Speedball pens. Poska pens, when empty, can be refilled with your own mixture of acrylic paints and water–pens get expensive at aprox $5-7.00 a pop and have limited color choices. In any case DO NOT USE OIL BASED PENS. Use acrylic water based pens. The key to a succesful paint job is the clear coat. I use Krylon brand, Ultraviolet Resistent Matte Finish Clear in a spray can; I have had no chemical compatibility problems whatsoever. It is widely available for aprox six bucks U.S. If you have an airbrush you can run other products for cheaper. A good art store will have all that you need. I recommend first, cleaning your board with acetone and/or firewater. Draw your design with pencil, you can erase with firewater and a paper towel. Then go to town with the pens. You can easily paint over colors with other colors as long as you wait for them to dry. If your skillful you can actually mix colors while still wet, e.g., yellow onto orange with a blending quality for flames. It’s quite fun to personalize your ride. After the clear coat, you can wax comb etc without any scraping or problems. Good luck. Jason
Addendum: There is no need to paint between glassing coats. You can paint pen after your board is completely glassed, sand or gloss finish. Just spray the clear (matte or gloss) when your finished.
Howzit jc, When my posca or zig pens are empty I refill them with india ink, which which works like a rapidiagraph with a felt tip. Try it they work great. Aloha, Kokua
jc, Thanks, you have been really informative and answered just about every question I might have!
