Date: Sun, 13 Jun 2004 16:45:53 -0400
Ken SchroeterHi, Paddlewisers,

Has anyone tried Krylon Fusion paint on their polyethylene kayak?

I have an Old Town Millennium 160 made of rather heavy polyethylene, which
over 5 years of heavy use has taken something of a beating. I am researching
a bit of refinishing.

I plan to lightly sand, then using a heat gun (less than 500 degrees),
gently melt down the more "hairy" areas, not fretting too
much about a couple of deeper gouges. Then I plan to apply a couple layers
of gloss (satin) Krylon Fusion (prep in accordance with maker) over a couple
days, then let it cure for 7-10 days.

What little I can find suggests that the old adage of "you can't paint
polyethylene" was specifically tackled by Krylon with this new paint, and
that this should work rather well. Most of the problems I found on the web
seemed related to people not prepping the surface in accordance with
manufacturers instructions (you do need to clean and wipe, etc, despite it
being a no prep paint).

Any thoughts?

Ken,

I have no info on the Krylon paint, but I'd like to add a comment on your 
proposed prep.  For some of the raised areas that you would normally sand, 
you might try a sharp cabinet scraper.  This is used in wood working all 
the time and leaves the surface smoother than most sanding (at least the 
coarser grits).  See any wodworking text for the technique.

Good luck,

Bill Leonhardt

Cool if it works!
I have a couple of plastic boats that I've been wanting to camouflage.
Definitely publish your results and anything you learn.

All I know about Krylon Fusion paint is that Aaron of Aaron's Rain Barrels 
recommends it for painting plastic rain barrels. However, my wife and I opted 
for an unpainted barrel. Though it might adhere well, I am sure it is still 
susceptible to scratches.

There is an article in a recent Consumer Reports about Krylon Fusion and a 
paint for plastic from another company (can't remember which).  I just 
glanced at the article a few minutes ago and they had a favorable rating 
for both products and specifically mentioned extra care in preparation for 
painting polypropylene plastic (sanding).

Ken,

I'd stay away from painting polyethylene. I don't know of much that will stick to it. You may also compromise the plastic by doing it through a chemical reaction with the solvents in the paint.

Your best bet would be the simplest: buy a bag of disposable razors and shave the hull. A razor will remove all the flash & fuzz & get you only as deep as you have to go. Then, coat the boat with 303, and it'll look a lot better. Heat guns & chemicals can have side effects that you don't want.

Ken,

I bought a can of Krylon Fusion a couple weeks ago at "Michaels" and followed
the "new" surface prep directions while applying it to High Density
Polyethylene ( HDPE)    I let it set-up  for nearly two weeks, and tested it
tonight after seeing your post.  Actually, I had forgotten about it until
now.

Krylon Test -
http://yostwerks.com/Krylon.jpg<http://yostwerks.com/Krylon.jpg>


I was able to easily scrape it off the plastic using light fingernail
pressure.   The HDPE  I used is a scrap piece left over from making folding
kayak snap-on cross sections.  I was hoping to try different color cross
sections instead of the white HDPE that I always use.  I don't believe it's
durable enough for my application ( Inside of hull).   Perhaps sanding first
could have allowed for great adhesion, but I'd rather have a smooth white
surface rather than rough it up.  Besides, Krylon says no sanding is
required.

Good Luck,

Tom
