Looking for very narrow filling knife

rodge123

Currently have a shadow reveal between door frame and wall (About 5mm).
There is a tiny gap of maybe 1mm between the inner timber and wall that I need to fill before applying paint.

Any tips on where I can get some tool in Dublin of 5mm or less to do this?
Working close to Stephens Green so somewhere in town would be ideal so can pick up on lunch.

Something along the lines of this I suppose:

That's the plan bit need a narrow filler knife or other tool to scrape it flat/flush inside the gap.

You don't use a filler knife with caulk, only with filler. Run a bead of caulk along the gap and smooth over gently with your finger

No you don't, just need something at least as wide as the gap, not as wide as the gap.

If you just want to close that gap then you don't need for the knife to get into the gap, as a matter of fact you don't even want it to as you want it to be even with the edge no?

Gap is too small for my finger to fit in order to run along the caulk, that's why I need something run along it and smooth/flatten it.
I'm not trying to fill up entire gap, just the recessed piece of timber and wall.

No, I want to close the gap between the recessed piece of timber and wall, it it set back about 5mm from outer edge of wall and door frame.
So I need a tool narrower than 5mm so that I can get in to fill and smooth//level.

yeah so all you need is something you can run along the edge of the timber on one side and the wall on the other side?

I'm not sure why you'd want a narrow filling knife like that?

I've done similar things with the back of a credit card before (less chance of scratching the wall)

Yeah I understand what it is you're trying to do I just don't understand why you want a narrow filler knife

Run a bead of caulk into it with the smallest end of the spout, nice and gently, then scrape off the excess with something straight flat and clean, clean up, job done.
If there's not enough there to get a straight edge run another bead until you have it the way you want it?

Yeah I suppoe could use something like a credit card, only issue with that is that it may be tricky to get a straight finish on filler or caulk as I'd have to apply horizontally.
I was thinking with a filler knife or something like it that was very narrow, that I could just run in down the recessed piece vertically and get a clean straight finish as it is running down along inner timber would help keep it flush.

Exactly what i want.
Was just thinking a tool that could be run down recessed gap vertically would be easier to do job with.

Pick up an artists palette knife in an art shop.

Could you get a small palette knife to fit into the 5mm gap, or cut a small piece of hardwood to 5mm, such as an ice-cream stick, and sharpen the end of it, and use to remove any excess filler or caulk, it would keep the shadow gap sharp.
