Best Window Sill Filler

[TheScullster]

Hi Guys

Something and nothing really! Can anyone recommend a filler for a gap between the back edge of an MDF sill and uPVC window frame please?

Gap varies from 1 to 3 mm.

I am looking for a filler that will be long lasting (obviously) and overpaintable. Not too struck on using uPVC filler strip, but would consider this if filler is simply not going to provide long lasting solution

TIA

Tes, the UPVC strips look naff. Use a wooden filler strip and paint/stain to match. For 3mm you could use a quadrant or round nose strip.

...can be difficult to overpaint.

Sounds like a job for frame sealant ;-), it's acrylic, flexible & will take paint. There's 2 white ones here:

Dry wall plaster(not finishing plaster) you can compress the stuff really into the crack and it sets rock hard in half hour then paint. oh and it don't crack as well.

Thanks to all

It's either the quadrant bead or the frame sealer. Sounds like one of those major life changing decisions that only SWMBO can make.
