What to use between render and window frames

[Alexphd1]

@nod or anybody else with experience.

 

We have 3-4mm gaps between the beads and window frames. Any recommendations on what to deal it with ?

Krend pure white colour.

We leave all like this 

They can crack the render in summer if they are tight Or left full

I was thinking of running a silicone bead up there such as ct1.

You can get window frame sealant, harder than silicone and doesn't fade in sunlight. And can get it colour matched to your frame colour if it's a standard RAL.

CT1 is really difficult to finish nicely and is prone to discolouring.

Sealant and K tend don’t go together 

Better to seal frames before render
