After the walls are finished how long do you have to wait to paint?

I ask because the paint shop (ICI Paint) says one month, while the contractor says more like two weeks as he knows when the paint is dry enough.

Two weeks is appropriate at this time of the year as the weather is cool and dry. A month may be needed during the rainy season.

Since the walls here in Thailand are rendered in cement I would wait a month for it to cure before painting

Two weeks is appropriate at this time of the year as the weather is cool and dry. A month may be needed during the rainy season.

Interesting that is exactly what the contractor said.

Someone else told me when the walls are dry they will be white.

Much similar to hanging wet clothes out to dry under shade. Dry windy conditions will dry clothes faster than wet and windy.

But surface colour is no indication for dryness a cm deeper inside the plaster.

The moisture has to leach out. I'd give it a month, unless you like painting and want to do it again.

You should also apply a coat of sealer to the render prior to painting - this is standard practice back home but I don't know if it's done here.

I am not overly concerned the contractor would paint again not me... smiling.
