Problems painting patio doors

[gretgret]

Hi,


Please can someone offer some advice on painting my patio doors. They are pine glazed doors painted with white gloss paint. I have just moved in so can't be more specific about what was used to piant them etc.

I attempted to piant them last summer. I sanded the rough paint off, filled the gaps in the wood with polycell wood flex polyfilla, sanded that perfectly flat, painted on an undercoat, then two coats of exterior gloss. A few months later, and the paint had formed creases and bubbled in places. It had formed blisters that you could burst and which were filled with a clear fluid. Where the paint had formed creases, you could pick the paint off with your finger nail, and see the polyfilla underneath which had expanded and was powder-like.

I attempted to sand back the worst bits, and then filled the gaps again with a two part exterior wood filler this time. I left it a while to see what happened before painting again - and sure enough it did the same thing once more forming creases and bumps.

Here are some pictures:

I have wasted loads of time on this already, so would reallly appreciate any advice to where I'm going wrong or what products I should use.

Many thanks,

G

The doors are knackered. Time for a new set.

Thanks for the reply, but they are barely 10 years old, have no rot at all, and are a big set of expensive doors. The pictures are just shots of the glazed sections showing the glazed sections.

Any other advice please?
