1953 Alcort Sunfish ZIP 11 Jun 20 Repair Area Stain Matching

11 Jun 20:

(Editor's Note: Let me start this blog post by recommending that you check with the manufacturer of the different products that you plan to use to verify compatibility. I bought a Minwax oil based stain and later found out on the West Systems website that it would be better to use a water based or gel stain underneath epoxy. And another option is to varnish over the stain vs coat with epoxy. We will need to make sure that the oil based stain is very dry before we epoxy over the top of it, but so far so good on a test piece. Ref West Systems 2013: Epoxy Adhesion Over Stains)

So here is one of the 4 cans of Minwax Premium Oil Wood Finish Penetrating Stain that we bought, the color that worked best on a scrap piece from the same panel as a the patch after about 4 coats was Golden Pecan #245.

I tried some stain on the backside of the patch piece and oh wow, there can be startling differences in color between different plywood veneers.


We put the first few coats on the patch piece.



And then I remember I'll need to sand wayward epoxy after the patch is glued into place, and that might change the finish on the original deck, and we planned to scuff the old finish to apply another coat of epoxy over the entire deck.

Now I recommend skipping ahead to the next blog post because it's about to get real confusing....

Thoughts on what needed to happen next, in random order...
The 7 year old epoxy finish on the deck needed to be sanded and I didn't know if it would refinish back to the same color, depending on how much epoxy was removed, so I didn't want to stain the patch too dark.

So sand the old deck, but not the patch area and reapply 2 coats of epoxy.

Then stain the patch area to match, let it dry and dry and dry, then apply epoxy over the patch area.

Wait, I better build caster bases for 2 storage cabinets first and paint the trim on them, an activity also know as "yak shaving" which are the things you do while avoiding the original task. See our blog on quick and easy storage cabinets.


Time to attach the patch with TotalBoat THIXO Wood thickened epoxy adhesive, wood colored. Remember to use a High Thrust 18:1 caulk gun to make your life easy.


Used clamps to provide light pressure on the joint while it dried.


We cleaned up epoxy squeezeout as best we could but we know a little finish sanding is in our future.
