We had our house exterior painted last November. Mostly it's fine, but the paint on 8 windowsills of the new extension (despite being completed a good six months before being painted) is flaking off in a major way. I assume this was due to rain before it dried.
It's not a big job so I'll do it myself, but I'd appreciate some advice. Will it be sufficient to roughly sand down the sills to remove loose paint and apply a couple of coats of Weathershield? Or do I need to apply some kind of sealant to prevent more flaking?
Many thanks.
