Hey folks!

I had a go (admittedly without a plan) at fixing a wonky windowsill in our downstairs loo a few months ago - I used polyfiller, chopsticks and credit cards to get it looking like this but as my fiancé pointed out we can and should aspire to a cleaner finish. Can you advise on which materials and equipment we should use to get a clean finish (nice straight lines, even surface) that we can then paint over?

Thanks a lot in advance from a clueless but enthusiastic DIYer
