ᐅ How often should you paint to achieve good coverage?

We have a thin coat render at 1mm (0.04 inches) and non-woven wallpaper on the ceilings and sloped roof sections. It is white and has no texture. Wherever there is drywall, the green color is still visible. Our general contractor contract includes only one coat of paint. The painter has now offered, without any self-interest, a quote for a second coat. I would have liked to see whether one coat provides sufficient coverage. I think it will work on the plaster, as it already looks good. But what about one coat on the green drywall panels? I would have preferred to inspect it first and then possibly commission a second coat. The costs are not insignificant, but the painter said I should let him know now so he can plan and order the paint straight away. I think he wants to put pressure on me and might be trying to earn some extra money. Maybe the general contractor negotiated too hard. What do you think? Is one coat enough?

But that is dispersion paint. I would only use silicate paint.

Why only silicate?

Sto Color Rapid white. I think the 20-liter (5.3-gallon) bucket costs around 70 euros.

We paid €72 for 12.5 liters (13.2 quarts) of Caperol Indeko Plus white paint (considered double coverage).

However, almost all rooms were only painted once. Sometimes, corners were touched up briefly.

There are areas with light/dark differences; for example, where new pipes were plastered over, these spots were painted directly with a so-called primer.

But in fact, almost all rooms were painted only once. Sometimes a few corners needed a quick touch-up.

What type of surface did you paint on? Have you calculated how much paint you used per square meter?

We outsourced the ceilings. That leaves us with about 600 m² (6,458 ft²) of walls with lime-cement plaster surface, finished to level Q2, to paint ourselves.

Yes, that can happen if the green walls are not primed first with a white primer.

Selflessly would mean at cost price.

That's why many people do the painting themselves.

Yes, it’s probably better if he has to have it delivered. Is there no specialist store near you?

Look, it’s his time that needs to be accounted for.
And of course his labor, and yes: that needs to be paid for.

Be that as it may, your house probably won’t be an expensive one.

Crystal ball reading?

He should prime with white first.
But he will do it, he’s a professional after all.

We applied two coats of paint to all drywall surfaces. It was necessary. The paint used was StoColor In, either RAL 9010 or off-white tinted. There was no other option. One coat is never enough, no matter what type is purchased.
