Afternoon folks,

I have the usual neglected timber soffits, fascias and barge boards on my house needing some serious cheering up. Can’t afford replacement so looking for any advice I can get on paint choice . I had a look around the forum already but not found anything within the last decade specific to this.

Plan A includes some rot hardener and filler in a few places (they are 95% still solid, though), so it needs to be an opaque (dark brown) coating and not a stain. Preferably satin, but gloss might be inevitable…

I believe they have been treated with stain in the past (no peeling paint anywhere), but I am not certain, it looks pretty opaque to my eye, so it might be well weathered oil based paint I suppose.

I’ve spent a good couple of hours looking for a suitable paint but ending up less confident the more I read, so before I start rolling dice I figured I’d fish for good old fashioned experience…
  • Any tricks or tips for testing what surface I have, and does this help narrow down my choices?
    • For example, water does not bead up on the surface – it seems easily wetted, does this mean Bedec Barn Paint (“not suitable for water repellent previous coating”) has a good chance of working?
    • If I get a blowtorch on it (and not burn down the house), does knowing whether it’s oil based or not help narrow down the choice?
  • Oil based generally seems like a PITA compared to modern water/acrylic based if I can confirm it will work – does anyone still recommend oil based under special circumstances?
  • Multiple layer paint systems like Dulux Weathershield etc. seem great for new wood but overkill in this case? – just trying to stop the rot, cheer it up and buy some time…Am I right to bin off these paints? I’m also doing this on a ladder and I insist on tying it back to the house, so it’ll be a fairly slow process if I have to do laps!
What I’m essentially after is an opaque, water based, single coat, fast drying, satin brown paint where I don’t need to care much about the old weathered coating, new filler or hardener, bar a bit of a rub and wipe down…too good to be true?!

Thanks in advance!

If the existing finish is waterbased, you can brush some cellulose thinners on to it, wait a few minutes and watch to see if the finish starts to blister.

From your description of the finish, it might be, erm, an oil based oil, such as Sadolin.

Photos will really help.

Here's a bit of fascia that's still solid:

Sadolin Superdec may well be the paint you want. Opaque, water-based, quick drying, no undercoat or primer needed.

You will need to sand the existing paint all over, but no problem with Superdec sticking to sanded oil-based or sanded water-based paint.
