Removing brown paint from under gloss?

[Ruggers]

I've been removing all the old gloss from my door frames with a heat gun and then sanding the wood down to bare wood so i can stain it.the gloss flys off but then there is a green undercoat which takes a lot of sanding to get off.

I've started to do the staircase and newal posts, again the gloss comes off easily, but there is no green under, instead it is a brown undercoat which the heat gun wont touch. if you sand the brown it seems to be silver underneath. Nitromors seems to turn it into a slight jelly which you can then remove some of it. I tried a belt sander on the flats of the newal posts which flew off but i'm unable to get this in around the stairs.

Any suggestions?
Any other paint strippers thats cheaper or better than nitromors?

You could try peelaway (or stripaway - not sure what it's called now). Unlikely to be cheaper than nitromors but might save you some time.

just googled it and its peelaway, i'll maybe try that and see how it goes.

There are two types depending on material to be stripped. I've used both on old pine wood and found the red one more effective. Sorry I can't be more specific but I just gave up trying to get to grips with the names.

If you do use it you might want to experiment with it first to see how long you need to leave it on before peeling the paper - too long and it will dry, too little and it won't remove enough paint.

I found it took a bit of practice to get used to applying the paper and probably ended up using more of it than I needed to. I used ordinary greaseproof paper at one point and that was ok (not as good though).

I ended up having to apply the stuff thicker than it says on the instructions, especially in the grooves around mouldings.

If you do use it hopefully it will go well and be nice and easy.

What is the paper part, do i not just paint it on then scrape it off?

I was going to email them and ask what they recommend as there are different number from what i seen

The paper absorbs the paste and prevents it from drying out too quickly. There are probably lots of factors that determine how long the stuff needs to be left on before removing the paper. I would leave it on as long as possible without letting it dry.

I had to apply the stuff with a filling knife - brushes eventually disintegrate. Once it's removed you'll need to wash it down well. I used a scrubbing brush but it was a bit messy although I didn't have to worry about that too much as the whole place is being redecorated, including floors.

It probably is best to get a recommendation from them.

You could also try nitromors. you paint it on then scrape off. Highly toxic though

I've been doing the same to my doors downstairs, the architraves didn't have it (thank god) but my 70's full glazed doors have this silver undercoat which was left after the gloss came off. Perhaps a fire retardant?

Did you get it off? do i need to apply a primer to it or can i use undercoat?
