 Post subject: Plywood
PostPosted: Tue Mar 09, 2004 3:58 am 
first, bad english ;)

My plywood board almost ready for the water now, i did use 4 + 7 mm plywood (fir) polyester between and 24h in the rockertable. Cut out the shape, drilled holes for the tnuts under the board and filled the holes with polyester. Now its time for painting, i will use a 2part epoxy paint (primer for boats under and over water surface) only primer becaus i think its looks nice when the finish isent so shiny..

My question, i have sanded the board, but the plywood is not smooth enough to paint on (it will look crapy)

What should i use to get a nice even smooth surface, before painting the board..

Again, sorry for my bad english

first sanding. then topcoat (polyester resin with 1-2 % parafin). again sanding and then top coat again ->sanding ->then painting.

The plywood is okay quality, but dont have a even surface.

If i put parafin togheter with the polyester, will it be easier to sand ?

Have tried to sand down polyester before, and it was hard..

Not sure if the polyester build high enough, the surface on the plywood is not even att all

Thanks for the replys

With all that work, are you sure you would't want to go with a foam core?
Just a thought.

Hope it all a works out :)

Polyester resin is easier to sand when you put pararfin in it. Then the resin becomes topcoat. Remember that parafin for resin use is highly dangerous for skin.
