Hello,
I have two window sills in an old cottage which were "updated" in the
'70s with dark red quarry tiles.

The rooms have been redecorated and I don't want the hassle of
removing the
tiles and replacing with mdf as I have recently done upstairs
..
I am thinking of painting the tiles,but need to fill the gaps in
between where the cement grout is lower than the tiles.
The tiles are level with each other.
I was thinking I might use a filler like car body filler for the
grout filling, then sand the tiles and the filler for a key then use
tile paint.
Would anyone make suggestions as to whether I should prime the grout
joints before using the filler and whether the tiles need priming
too ?
Perhaps there is something better than body filler for the joints.
I know it is a compromise, but the result, with care, should be much
better than the present dated look.
The windows themselves are PVC double glazed so the contrast is even
greater.
Your thoughts and efforts are appreciated. Thanks for reading.
