How to fill window sills

King Mallie · 2011-04-28 22:01:39

Hi All, On my conservatory between the sill joints (as conservatory has two 45 degree angled walls and one 90 degree) the mortar has fallen out and thinking about painting house this year so I will need to fill the joints in concrete window sills. What is best thing to use ?? Mortar or some type of filler ?? Thanks

mortar.
mix it stronger than usual, around 3:1.
Trowel off a nice smooth finish when it begins to get stiff.
