Gap between window and sill

[AndyJ88]

Hi.

I am sanding and painting the windows as they a bit of a mess.

Any idea what to fill the gap between the sill and the window with? I bought exterior sealant but it says it can’t be painted.

The sill tiles are also a bit of a mess. Do people generally just paint these with masonry paint?

AndyJ88, good evening.

If it were me? i would fill the gap with putty, cheap cheerful, easily replaced and when set paintable, as well as reasonably flexible.

As for the tiles? there are external specialist tile paints, but?? over time this paint will peel and fail.

Ken.

Thanks Ken. On the paint, do you mean you would just use masonry paint or you wouldn’t paint it?

Personally, I would not paint them, you end up with an on-going maintenance issue.

I also think that retro painted sills such as yours [very personal opinion here] do not look "correct??

An exterior grade decorators caulk would also fill the gap. It's paintable.

Be aware not to get the interior stuff, which is more frequently found in DIY shops.

I think the last exterior caulk I used was Painters Mate.

I would use a MS polymer. They are flexible like silicone but can be over painted. Note, you need to prime them with waterbased paints first. Oil based paints remain tacky if you don't use waterbased first.

Decorators caulk might be ok but it goes hard in time and is less flexible.

Examples of MS Polymers are

CT1 , SikaFlex , Stixall

They will even stick underwater.

Dip your finger in white spirit to smooth the bead.
