Woodfiller and glue

[Kyak]

What kind of filler do you guys use after first planking and what kind of glue do you use for second planking?

 

I would like to use pva glue for the planking, i dont have no idea what filler to use.

I do not do POB hull assembly,  but  if the gaps are between the planks of the first layer, why fill them at all?  The hull is not meant to float.

If there are flats and hollows, PVA bond thin pieces of wood or veneer to build it out and abrade that down to a fair run.

PVA bonds by assembling chains and tendrils that invade the pores and rough surfaces of wood - as well as twisting around each other. 

A surface finished to 100-120 grit seems to be optimal for a good bond.  I break my own suggestion because I came to favor 220 grit before I knew better.

Using wood strips for flats and hollows works well. If you have a smaller irregularity you want to correct, use wood putty and then sand with a fine grit. You do want to have as much wood to wood contact for gluing when you lay down your second planking as possible so don't go to overboard with filler. For wood to wood gluing use wood glue pva. Only use ca when you are bonding metal to wood and be careful as it stains the wood and is tough to sand out.

Be careful what filler to use, some trade ones are rock hard when dry. Modelling ones or Elmers are good choices, they sand nicely
