painting ash

[wallace]

I was recently asked to make a window sill, it was to be sloped with a drip edge and made from hardwood. I had some ash so used that. The person rang me tonight and said that he had painted it and once dry the paint had flaked off. Can anyone think of a reason for this?

It sounds like he has used a water based paint.

Ask them what primer they used.

PS Although ash is a hardwood it is classed as perishable so not a good choice for a window

more than likely they've used an acrylic gloss without any primer and undercoat- it might also be that the wood has got wet and they've unknowingly painted over the moisture.

No problem applying water based to wood, if in doubt, try painting a bit of scrap with emulsion and see how well it sticks.
