Tempera Paint Crack Prevention?

great videos, Barry.  thanks for putting those up.

all the best

If your paint is cracking you are using too much paint, applied too thick, and you have not waited long enough between coats. This applies to all paints. Cars, houses, airplanes, boats ect.......

Thick coats applied on a hot day will cure on the outside...not the inside. Painting foam is not the same as painting a sanded hot coat......

At what point did you decide that a concrete resin additive was good for thinning Tempura????

You lost me a long time ago...painting surfboards is really simple...........Let's keep it that way.

Barry, Nice work in those video.  The Einstein looked great.  

Hello BarrySnyder, I remembered this thread so took some photos with Tempera paint and several colors, taping over etc.

-so you see the difference in the tempera brands; the Magenta is thick and high quality that I order directly from the factory, the other is the normal tempera from a big factory; its more diluted and do not have the same % of pigment.

sick paint job. Question, how did you manage to keep the line so close? Start with darkest color then pull tape for next color and spray then so on till the yellow. Each color laying over the one before? Example Dark magenta then pull tape for red spraying red over magenta too , then orange going over all untaped areas then yellow going over all ? Confusing writing this but hope you get my question and example.

…hello Bluefin; the other way ´round.

Start with lighter colors first. 

Im assuming you retape as you go if starting with lighter colors? I’ve done multiple colors but usually have at least 1/8" tape line between each color due to having shit success with touching colors. Usually get a visible over lap of mixing colors hence the 1/8" tape line. I’ve seen a friend do multiple lines starting with the darkest and then the lighter which worked but the first color usually changed due to the mixing.

…yes, re tape; time consuming stuff… that you cannot properly charge.

Couple of tips I can share are: use slow pressure and the angle of the gun is very important; play with that to avoid bleeding. Use a hairdryer to remove tape.

Never thought of the hairdryer to soften glue on tape trick. Guess it comes down to having a ton of sprays behind your belt to perfect that. Either that or my taping sucks arse. I’ll go with the tape job sucks . Thank for the tips. Again nice spray job reverb.

Between Atomized, Barry’s, pics, Reverb’s multi colored back to back razor sharp tape lines etc, I’m completely depressed.  I give up!  #@!*$

I’m sure most of you recognize the green paint disaster attempted coverup here below the wavy black outline

 

When you have to do multiple tape off lines try spraying a tine coat o clear before you back tape. The tape is less likly to pull color. make sure the tape edge does not allow for paint to bleed under. Multiple thin coats work better then doing one or two thick coats.
