Decorator caulk or silicone around wallpaper?

[Adam78]

Hi,

I want to tidy up the joint between where wallpaper meets a timber window frame. Not sure what product I should use. Would acrylic decorators caulk be ok or should I use silicone and if so is there any recommended brands e.g painters mate?

Also around this join i.e between the window frame and wallpaper the area seems to be prone to mould. Is decorators caulk mould resistant.

Any tips and advice would be much appreciated.

Decorators caulk ideally rather than silicone.....so long as the gap isnt big!
If its on the large size, consider some timber mouldings pinned to the frame which could be neater.

Mould due to poor ventilation.

Geocel painters mate would be my go to or a hybrid paintable sealant/adhesive.

CT1. The flexibility of silicone with the paintability of caulk.

It's quite expensive so consider doing all cracked window joints in the house!
