Verify my plan for artwork process on hotcoat

General Discussion

Hey sways,

Im looking to verify my procedure for artwork on hotcoat, underneath gloss coat.  Poly resin.  I have only been working with epoxy with no art so I could use a tip or two with poly.

Board is a dumpster dive reshape and glass so that my daughter can do some artwork on the bottom - Im sure it will get surfed.  She has a plan for acrylics that will be free handed with a brush.  Through searches here it sounds like acrylic paints thinned 2:1 with water is the way to go for brushing.  Mostly wavey lines (think kelp, vines, etc) not broad areas of paint.  She is comfortable with a brush - I mentioned paint pens and she would rather use the brushes. 

My confusion lies in what sanding will best hold the artwork and also the application of a gloss coat.

I did a bunch of searches and I think I have it as follows:

  1. Lam
  2. Hotcoat
  3. Sand hotcoat.  This is where the confusion sets in.  It looks like stop at 150 if going straight to gloss coat.  I have seen it suggested 220 grit on the hot coat for pinlines areas with acrylic and up to 400 on the hotcoat for acrylic artwork.  I guess Im worried that a 400 finish may be too smooth to give the poly gloss something to latch onto.  Will 220 hold the acrylics and gloss or will 400 do both?
  4. Paint artwork on hotcoat
  5. Let dry thouroughly
  6. Should I spray coat of clear acrylic sealer? Some think its needed - others seem to be OK direct gloss over the art
  7. Lightly sand/scotchbrite the artwork/board and apply gloss coat.  Same as item 3 -- What grit doesnt take too much off the art/sealer and allows the gloss coat to latch?

I could also just apply an acrylic sealer coat over the art and call it done -- but Im thinking a nice poly gloss coat will be tougher and allow me a chance to play with poly buffing/gloss.

Any comments or suggestions is appreciated.

PS - Ill try to grab some photos when this goes.

Thanks in advance for taking the time to spread your experience with others less experienced like me - I greatly appreciate having a place to read, learn, ask.  I have learned tons since comming to sways,

Thanks to all,
