Need advise! Is this a disaster waiting to happen?

Postby DrBryanJ » Sat Aug 26, 2017 11:51 am

Went to the garage today ready to stain the sides. ( It has been sanded smooth to 150 grit.) Noticed areas where the wood filler has come out of seams. Can feel a ridge at joints when running hand from chine to sheer. Are my cover boards coming loose? Is this caused by drastic changes in humidity of last few days? What to do now? or should I do nothing but refill the seams and go on from here?

Finished prep work on wood yesterday. Some vacuuming to get ride of all the dust and finally ready to stain. With the help of Lisa (with some complaining), I got the sides and transom stained. Used General Finished Brown Mahogany.

Used method described in video from General Finishes.
Sanded to 150. Cleaned wood with paper towel then tack cloth. Used Surgical Blue tack cloth, doesn't leave wax or varnish on wood. Wet with mineral spirits as a slip coat. Apply stain. Wipe off with lint free cloths.
All the little staple holes have virtually disappeared.

Looks a little dark, but when I had my test board in the sun it was much lighter.

Looking good Bryan, I bet it feels good to get to this point. I remember how I felt when I got my transom stained. That seems so long ago now!

Wow! Looks great! Can't wait to see it varnished up nice and shiny, that will look awesome.

Thanks Carl and Peter. Yes Carl it does feel good. Getting closer to the flip. I can't wait.
Forgot to say the stain was diluted with 10% mineral spirits per General Finishes for large projects.

Wasn't super happy with color. Just seemed too flat. Put a second coat of American Oak. Didn't change the color much, just made it warmer. Garage is too dark now to get a picture. I'll post one tomorrow. Lisa didn't notice any difference. She thinks I'm crazy. She just wants it done and out of the garage. She's happy I cleaned up all the dust though :lol: :lol:

Put two coats of epoxy on

Started lightly sanding with 150 grit paper.

Don't want to sand through epoxy, but will these low spots fill with additional coats? Should I continue to sand until they are gone from these two coats?

Sanding with a longboard between coats, once your sandpaper is touching 90% of the surface area (only missing small specs such as shown), quit sanding.
How many coats of epoxy total are you planning?
What epoxy are you using?
What finish product do you plan to use?

I think 5 or 6 coats of epoxy.
I'm using system 3 general purpose with slow hardener (It's what I had on hand.)
I haven't decided on varnish or wr-lpu clear.

It may fill during your subsequent coats. Apply a couple more coats and see. If still not filled before applying your final coats, mix up some GelMagic and apply with a squeegee to the spots. It will cure clear and has enough viscosity that it will shouldn't run out. Then sand to ensure that they're filled and apply your final coats.
