Silicone sealant for casting insitu window draught seal
 

I'm sure I've seen mention of this technique in the archives, but can't find
it now.
Idea being with my very uneven gaps on softwood casement openers, to:

1/ Open window
2/ Cover opener contact points in suitable release agent (Cling film,
silcone or PTFE spray?)
3/ Seal on to frame in the proper position of a typical draught excluder
with low mod silicone.
4/ Close window to vent position
5/ Time passes...
6/ Open and trim with knife as necessary.
7/ Have lower bills and more comfort.

Anyone like to add anything to help task satisfaction, esp concerning
release agent.

I've posted that I've done it in the past.

I used low-tack packing tape.
As I could find no low-tack packing tape, I simply used ordinary packing
tape, with the teenyist bit of cornflour applied to it.
With 'Flora Buttery" over the top of it, as a release agent.

It's essentially impossible to get it very neat.
If you can get to outside the window, then it may be possible to remove
the excess in a neat manner.
(white spirit soaked rags help lots)

Of course, for really rotten windows, just omit the tape...

Ive found a scalpel blade and peeling back excess is a great way to
neaten silicone.

Yeah - it's not impossible, just really annoying, especially if perched
up a ladder...

It may be faster in some cases to simply unscrew the window tops, after
casting the large glob of silicone, and do it flat.

You have the technique about right, it is common sense.

The release agent I used was candle wax. Just rub a candle on the bits
where non-sticking contact was required.

In the original thread you recall, many agents were recommended as you
remembered.

Ther comments were the use of masking tape to cover bits where you
didn't want the sealant to wander to.
