We have stairs leading down to our flat which are outside and we have painted them a few times, but the paint doesn't seem to stick very well, and always starts peeling off.
It mainly peels in the same places, which is where water drips on the stairs from the balcony above when it rains. We can't stop this dripping and so I want to know what my best options are for painting that will minimise the chances of it peeling off.
Previously the old coats of paint were not properly removed (the work was always done by people organised by the managing agents, we will be doing it ourselves this time) and so I'm going to use a drill scrubber to try and remove the paint first.
But is there anything else I can do?
Will adding PVA to the paint make it more likely to stick?
Is there some paint that is better to use?
