UV Smooth Prime is a waterborne
urethane. It is used on composite aircraft to protect the structural epoxy of
your composite surface from harmful UV light. It also provides an
easy-to-apply, sandable coating and fills pinholes in your composite surfaces.
When used in conjunction with Superfil, these products give a marvelously
smooth platform for your final 2-part epoxy and top coats. The result~ a
beautiful paint job!
How do I use it?
Smooth Prime may be applied with a foam roller.
It's that easy. Follow the mixing instructions on the can. Apply 3 coats and
allow it to dry. Sand it to get a reasonably smooth surface. Then apply 3 more
coats either by roller or by spraying. Allow this to dry well and sand again
gently until you have the level surface you desire.
After applying UV Smooth Prime ~
Let it dry for 7 days. If you live in a cold,
damp climate invest in a dehumidifier ~ buy or rent it. ALL WATER must be out of
the UV Smooth Prime before it is over-coated. Next, you will need to seal the
UV Smooth Prime with a 2-Part Epoxy Primer like Poly-Fiber EP-420 or Randolph Epibond Primer; both of these are available through us. Allow the epoxy primer
to cure for 1 week.
What coatings do I use for my top
Over your now epoxy primed and UV Smooth Primed
surface apply a top coat urethane. Either Aerothane or Ranthane are ideal
aircraft-grade top coat urethanes and will provide a beautiful, glossy finish. (In the event you use another manufacturer's 2 part epoxy primer,
we recommend you use that company's top coat paint to maintain
