Exposed Weave Frustration

General Discussion
1

I'm trying to build some summertime fun boards for my nephews and need some advice on how to prevent weave exposure during sanding...

Everytime I do colored rails (airbrushed foam) I expose the weave during final hot coat sanding. I'm only hitting the rails with 220 and 320, but am still encountering the problem. Is this a preparation issue or am I running the disc sander to fast? Should I be using the soft as opposed to medium pad?

Boards are due to these groms in a few weeks so any help would be a blessing.

 

Thanks,

Schieb

try doing the rails by hand with a block till its almost all dull then a few swipes with folded paper to get the left over shiny spots

the pro sanders can use a power sander cause they have the touch,

it doesnt take long to do it by hand

be carfull at the nose and tail

Depends on where your getting it.  Is it the rails, bottom lap line, deck?  Instead of fighting it I do a more thorough prep sand before the hot coat.  I was having problems near the nose on the deck, rails, and the bottom lap.  So I take a hard pad with 100 and flatten out the bottom lap, 100 on the rail, and 100 with a d/a on the deck near the nose.  I use my hand to feel for bumps and high spots and make sure I sand them flat before the hot coat.

Bottom lap always gets a baste at the lap line before the hot coat.

Sanding is 100 then 220 with a medium pad, then acrylic spray.  If I still have weave after the 220 I'll make sure it is flat with 220 then give it a thinned coat of resin applied with a squeege.  Then a quick sand with 220 again to smooth it out.
