Help!!! Cetol 1 on cedar garage doors

13 years ago

We choose to use Cetol 1 + Cetol 23 in dark oak for our cedar garage doors. So far our painter has applied one coat of Cetol 1. One of the doors looks 2 toned. It's really strange. It's the door on the right. The top half look right, but the bottom 1/2 look completely different from the other doors and the top helf. Any ideas on why this may have happened? Will it even out when we apply the Cetol 23 or should we remedy it prior to applying the Cetol 23? I would also like it a bit browner/darker, will applying another coat of cetol 1 do that? Will applying another coat of Cetol 1 also even out the tones a bit? HELP!!

Yep...

You're dealing with 2 different sun exposures. PLUS, the wood itself is variable too...no controlling it...much!

SOME evening-out may occur. Don't count on much however!
>>> Don't add a 2nd coat of Cetol 1. It's only meant to be the initial "primer" layer. On furniture however, you can use 3 coats of Cetol 1.

Things will improve SOME after 2 coats of the 23+, but again...not much.

>>> Were the doors sanded to remove any mill-glaze b4 he started? Was any other prep done?

Respectfully disagreeing with JH on "Mill Glaze"...

EVERY deck-stain & Interior stain I've ever dealt with stresses light sanding to remove the slight "polishing" ("Glazing" effect) that wood undergoes when it goes through the planers.

>>> Sometimes it's visible...sometimes not...

It's just a simple fact of the wood-finishing/manuf. process. Wood re-finshers I know, and many dedicated woodworking magazines, etc., speak to this very issue.

The glazed effect can vary noticeably...ON THE SAME BOARD...when staining.
* Glazed areas don't absorb much stain, because the wood cells have been polished.
* More "open-grain/unglazed" areas take in much more stain.
* Therefore, noticeable color-variance is routinely evident.

Sikkens Not UV-stable?!
Well dude...technically speaking...NOTHING on this planet that's semi-transparent is 100% UV-stable. It's just not possible.
If you can see the woodgrain, so will the Sun's UV-rays! Wood WILL suffer UV-degredation. Even solid paint suffers after a few years.
For those who want to see their nice wood doors, Sikkens is one of the few things out there that has a nice sheen, and holds up for a while.
There's a LOT of nice garage doors around here with Sikkens on-'em...and we go through a lot of Sikkens. No complaints here.

Throw some FACTS out there for a change JH...
