Best paint finish for wood windows?5/1
I am building some wood windows, which is not my primary area of expertise (they are for myself, and not for primary residence). I am clear on the joinery, seals, hardware and glazing aspects.
I would like to give them the absolute best chance at long term survival. What would be the best paint/finish schedule? I am open to any suggestions, but would prefer something I can spray with HVLP if possible.
Here is what I was thinking, please advise if I'm way off base, or have the order wrong, or if there's something better.
1. Paintable wood preservative (like Rustoleum Woodlife Classic)
2. Spot treat knots with shellac(attempting to select the clearest wood, but there will inevitably still be a few knots)
3. Prime & paint, exterior latex.
Final note: I know, I could buy cheap PVC windows, throw them in and have a problem free product. But I enjoy the technical challenge and a failure would not be catastrophic (not a residence, and not for a paying customer).
Thank you for anyone who might contribute advice.
I would not use shellac on exterior work, poor water resistance since it is thinned with alcohol. My favorite saying, water and alcohol mix, it's called gin and tonic. I'd do the painting before installing the glass. Up until a few years ago, the longest lasting method was an oil based primer with an acrylic based top coat. Not sure if the quality of acrylic primer has caught up, or even if oil based primer is still available.
Thanks... this is exactly what I was looking for.
I think I still have access to an oil based primer from SW.
In your opinion, would the wood preservative before the primer be overkill? Or detrimental? Or would it still do some additional good?
My opinion, if you do a good job with the painting, and maintain the windows, water will never get to the wood. Preservative not needed. The huge caveat, is the maintenance.
The secret is letting the wood breath . Plastics likes shellac or oil based polyurethane stop the wood from breathing .
My shop is on the ocean 100 ft away learned the hard way
About 8-10yrs ago I stripped all my wood doors and sliders of marine varnish over stain to raw wood. We're talking 4 exterior doors, 2 12ft sliders, 1 6ft slider and 2 sets french doors. I used Zinnser oil based primer and top coated(2 coats) with Ben Moore Aura. I've had one re-coat on the south facing units and they need another soon. I've used the Aura on a couple other exterior projects and I'm convinced. Pricey but does a great job. Lots of pigment and covers really well.
