Filling in gaps in wooden staircase - wood filler or caulk

[darrenbgray]

Hi,

I am about to embark on painting my staircase white and am wondering what I should use to fill the gaps, wood filler or caulk? I've attached a photo to help.

caulk would be my answer, then use a good sealer against the varnish/wood stain, undercoat ( two coats) and finish coat

Caulk for sure.... A nice neat stream of caulk in the gap and painted as mentioned by bosswhite. Keep the caulk to just a thin neat constant stream so as to avoid running your finger along and creating another line in the caulk.

You have to be careful with caulk, cut a small angle on the caulk nozzle, slow and easy better to fill twice than too much. I use a silicone tool to remove any excess: See Here These are the best i've tried for awkward places. make sure you have some wet wipes too to clean your hands and any tools.

Thanks guys for the advice. I will give it a go with the caulk as suggested
