sanding Hot Coat if no Gloss Coat

General Discussion

I did my Hot Coat and I am “reasonably” happy with it. I would like to not do a Gloss Coat for a couple reasons.

I want to save the gloss resin for my next board ( I had to do 2 hot coats and lost a lot of resin due to mixing too much resin). I am not really happy with this board and don’t want to invest anymore material in a board that will be a loaner board.

Can I just start sanding with 220 grit and work my way up to 400 or 600?

Reading the article below from the archives it just seemed that if I started at 100 grit I would go through the Hot Coat easily because it seems to be thin. Correct?

"Generally, grits of 100 to 220 are run at about 5,000 rpms (hot coat). Be sure and get a “Power Pad - soft” — its the best, accept no substitutions. 320 grits and higher (often used on gloss coats) are run at 2500 or less. High rpms with fine sandpaper generate a lot of heat – keep it moving or you will get “burns” – tan spots – or worse. Use Silicone Carbide paper.

As for gloss coats: I sand them out with 320 grit and the power pad – then, I move to 600 on a pad called a “Disket” which is stiffer and flatter and use it at real slow speed with some water on the board. Then go to 1000 wetsand and a hand sand – polish with polishing compound (keep it out of the sun) polish off dry compound with wool bonnet. The look is totally liquid when done right. Practice on an old board or something else before taking your act live. "

I’d start and finish with 220 than brush on clear acrylic finish to seal it well.

Future Floor as a finish ok, or do I buy a clear paint? Spray on or hand rub?

I have the spray tools, but would prefer to do it by hand.

Thanks for the help.

You can brush it on following the directions.

But I was thinking further…for about 40 of my boards, I stopped production at the completion of the hotcoat! No sanding, sureforming, except the rail lap line, but I did rub the wax out a bit.

That semi weave showing finish sure seemed fast.

Of course, that was after 30 odd lams, so no pinbubbles and the laps all prepped before hotcoat ( sureformed and sanded smooth as the finished board).
