The baseboard of the stairwell was painted with oil paint, very durable and technically in excellent condition – only the color was no longer appealing. We requested quotes from painting companies and chose one of them.
The master painter inspected the stairwell and proposed to thoroughly strip the baseboard and apply two coats of paint in a color of our choice.
The stairwell was nicely renovated, and a few weeks later the first move-in took place. Afterwards, the condition was awful: there were many scratches above the baseboard, and the paint on the baseboard was peeling off in large flakes, while the substrate underneath appeared undamaged and glossy in the old color.
The peeling paint flakes came off like poorly adhered wallpaper – the paint simply did not stick to the old coating. (The damaged emulsion paint on the upper wall areas and ceilings is not the issue here!)
We filed a complaint, and the painter agreed to remove the paint and redo the coating.
He consulted the paint manufacturer and was advised to apply a primer on the sanded substrate, followed by two layers of acrylic paint as before.
When sanding, some remnants of the old paint remained in the depressions of the lightly textured substrate.
Now it turns out that the new coating, which is about 10 days old, is still not very durable. It adheres better than the first one, but you can still easily enlarge scratches in the paint with a fingernail. The primer comes off as well, revealing the old coating again.
In hindsight, I realize: an oil-based paint should have been used on top – but the master painter should have known that long ago.
Before, we did not like the color, but now we have a real problem. What should we do?
