UPVC Window gaps internal

[Notadecor8ter]

Hi,

I have taken this window back to masonry to retile.

Original windows were late 90's build and They were added in.

Its got some lovely gaps.

Do I remove the damp sheet and foam in all around this gap?

Do i do this with the bottom as it will need 40mm of tilebacker. I can see why the original sill had abput this in plasterboard adhesive!

Is Soudal PU adhesive foam suitable as ive gpt 3/4 of a tin left!

the excess overhanging vertical dpc can be trimmed a bit then foam as you say. The foam you’ve got is fine

I’d probably foam at the time of fixing the reveal boards and stick em on with the foam

Leave the DPC where it is as it's protecting in from out, i.e. all the external bricks visible are potential cold and damp spots. In reality, the window should be set as far back into the room as possible so that the junction between in and out is spanned by the frame. The external bricks should never meet or touch the inside material.
When you do dab the reveals, try and ensure the adhesive never touches the external masonry.

If there is any excess DPC visible once the reveals are dabbed, you can carefully trim it off before skimming.
