Inside of exterior door... satinwood ok?

malexicon

Hi there. I am about to redecorate my kitchen, I have a side door from the kitchen to outside. I am not painting the door on the outside, just inside. I also have an interior door into the hallway in the kitchen that I intended to paint with some interior satinwood - will this be ok on the inside of the exterior door? The exterior door is rarely opened, maybe a couple of times a week so is not really exposed to any of the outside atmosphere at any point. I am not 100% sure of the material of the external door itself - its not UPVC - may just be some kind of hybrid wooden door? Any suggestions would be helpful if the interior satin doesn't seem the best option. Thanks

Well, interior paint is certainly fine to use, because it's on the interior

But whether a primer is first needed is hard to tell - it depends on the surface finish. 

If it's already painted, then water-based satinwood will almost certainly go straight on, but always clean down the surface thoroughly first, and ideally 'key' it slightly, if just only with a scourer. (Or ~180 grit paper).

If it's a composite door - ie likely to have a 'plastic' finish - then you 'may' need to first use a universal primer such as Zinsser BIN, or else use a 'specialist' paint such as Zinsser's AllCoat, which will basically go on to pretty much anything, and is super-durable too.

Thanks Bendy - you have been a help to me before on other matters so your response is always appreciated. Had a look at it there - ran my finger over top of the door and its wood and already painted so interior satinwood it is. I have already cleaned down will lightly sand before popping on a couple of coats.

Mrs Malexicon wishes me to paint a dark stained, varnished staircase - so I might be getting some Zinsser in at some point if I can't manage to put that off any longer - many folk swear by their stuff..

Thanks again!

You're welcome.

This staircase - what colour would it be painted? If it's, say, white, then I'd give some thought to going straight to Zinsser's AllCoat rather than Zinsser primer and then a 'standard' topcoat.

The only issue I've had with their exterior AllCoat is that it dries quite quickly, but then so do all water-based paints in the blazing sun we've had. Other than that, it's great to use - the second coat goes on sooo much nicer than the first, and it's genuinely tough stuff.

That's their exterior stuff ('15-year'), so might be overkill for the inside, but I don't know if they do an 'interior' equivalent?

Hopefully others will advise.

(I've seen folk on her use their AllCoat to paint their exterior doors, both composite and wood. Finish was superb. I've used their ext white gloss on MIL's windows (straight over (clean) old paint, exposed wood, and new filler - no primer needed!), and I'm confident the finish will last donkey's, and their ext satin in anthracite to completely rejuvenate the faded bumpers and wheel arches on an oldish Transit. 2 or three thin coats rolled on - looks like new parts. Amazing stuff.)

I’ve just painted a couple of old fifteen pane glazed doors in white Dulux Satinwood Quickdry.
Needed three coats on a mahogany colour one side and two I think on the white side.
Said no primer needed and the finish is good. Just need a few coats.

Cheers guys. It's the satinwood quick dry I have for inside am covering white so hopefully a couple of coats will do. We are looking at painting the staircase white so a zinsser deffo required of some kind given its current finish...that said ive got a carpet on that to circumnavigate which I am currently using as an excuse to delay!

If you read the instructions on the Dulux tin, it should say whether a primer is needed for bonding reasons. Tbh, you may wish to use a white primer anyway, as Satinwood is quite translucent, so may require more coats than you anticipated.

I'm not a painter, tho', so don't really know what's best.
