I've a brown wooden door which is peeling yellowish flakes all over and
the bottom floorboard (cherry?) is worn to the bare wood getting wet in
What do you put on this kind of door to protect it?
I do not think storm doors would be apropriate in this set up as it is a
front door to the house with a big opening and side panel.
This is what the outside is peeling like.
The inside is very dark stain of some sort.
Your advice is suggested.
Your door looks to be Phillipine mahogany that has been varnished. The
varnish is in terrible shape and needs to be totally removed either by
sanding and/or scraping or chemically (paint remover).
Once the existing finis is gone you have to apply another. You have two
options: paint or a clear finish. If you want a clear finish, you have
these choices: varnish (poly or not), lacquer or oil.
No finish will last indefinitely. Paint will last the longest. Oil (tung
or boiled linseed) is the easiest to apply and reapply. Varnish in your
situation might go for a couple of years before it needs renewing. Maybe
longer but not much.
If it were my door, I would use a marine varnish making sure it had an
additive for UV protection.; 4-6 coats. I always liked Z-Spar varnish,
would probably use one of these...
The trick to maintaining a varnished surface is to add another coat at the
first sign of disintegration. That would be dulling; lifting or peeling is
too late. When redoing, the surface should be sanded with fine (180-240)
paper to remove the oxidized layer, provide tooth and to avoid building up
an excessively thick layer of varnish.
The door is very dark on the one side away from the sun.
It is very light on the other side facing the sun.
Do you think there is stain on the door in addition to varnish?
Here is the inside of door color that I wish to match on outside.
Do I add dark brown stain to the varnish first?
What size is that door ?? I had similar setup with single pane, and 36 inch
solid wood door. I installed insulated window pane, because it was too
cold. Wood was just painted, not stained, except I redid the rear of the
door back to stain.
The opening is about 7 feet by 7 feet. The glass is two pane thick.
The door itself is only 3 and one half feet wide and feels like solid.
I do not think I want to paint.
I want to stain to same color and then protect best.
In this picture taken right now you can see the two different stain color
at the bottom of the door at the "sill" on bottom.
I'd look here
Sikkens make some very good products, but being all wood,
there is nothing that will last forever.
Prepping it properly then using Sikkens and doing regular
touch up and maintenance, it would hold up a long time
Floorboard? Mean the lower part of the door? I would not use clear
finish on a door getting lot of sun....sand, prime and paint it and then
put some sort of kick plate across the bottom. Of course some sort of
awning would help...clear finish in strong sun works a little like a
greenhouse and lets sun deteriorate the wood more quickly.
Maybe that is the problem. There is awning but it faces the sun so it is
You suggest brown finish but is that varnish or stain or urethane or what
is best for brown door all wood very thick and very heavy?
Just out of curiosity, how much of the door and sill are exposed when
the sun is on it? South side of house?
First, it appears that part (or all?) of the peeling problem is due to
moisture seeping into the wood through the joint at base of door
frame...I don't think it would peel that badly if just sun and weather
caused the problem. In order for any finish to adhere you need to sand
away the weathered (gray) wood....looks like a very nice door and home,
so sanding should be done carefully. It also looks as if soneone
applied a water-based clear finish to damaged wood; that is a poor choice.
If you use a clear finish, I would make it solvent-based. First two
coats should be thinned as much as the label allows. Brand? Just pick
a name brand. Be sure to recoat according to label instructions and not
during hottest sun exposure. When the finish is CURED (not just dry),
apply a clear caulk into the joint. The sill could probably use one or
two more coats that the door since it will have more wear. Two,or three
at most, should be plenty for the door.
If painting, sand as before. Then prime with oil primer (I think oil is
better on exterior wood because it sinks into the grain a little
better). When primer is set, apply paintable caulk along all seams,
pressing into the seam and smoothing the surface. Two coats of
semi-gloss alkyd paint from a good paint store.
Yes. South. Sun all day. Rain blows in with wind. Always sun. Always rain.
So I need best protection I can give the door. Plus it must be darker.
Here is the picture taken just now showing it already being wet outside.
I see you said not to use water based. I will use what people suggest so
no water based varnish.
