How many coats for good coverage?

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

Why only silicate?

What is the exact name?

Sto Color Rapid white. But I think the 20-liter bucket costs around 70 euros.

We paid 72€ for caperol indeko plus 12.5l white (considered double coating) but actually painted almost all rooms only once. Sometimes there were corners that were quickly touched up. However, we have spots with light/dark changes; for example, where new pipes were plastered over, they were directly painted with so-called primer.

On what substrate did you paint? Have you ever calculated how much paint you used per square meter?

We assigned the ceilings. Then about 600 sqm of wall surface lime cement plaster Q2 remains for us.

Everywhere there is drywall, you can still see the green color through.

Yes, that can happen if you don't prime the green walls whitely beforehand.

The painter has now helped us completely selflessly

Selflessly would mean at cost price

The costs are not insignificant,

That's why many do the painting themselves

however, the painter said I should say it now, then he can plan and order the paint right away.

Yes, it's probably better if he has to have it delivered. Is there no specialized trade nearby you?

I think he's trying to make some extra €.

You see, it's his time that needs to be calculated.
And of course his labor, and yes: that has to be paid for.

Maybe the general contractor negotiated too hard.

Be that as it may, your house is probably not an expensive one.

What do you think? Is one coat of paint enough?

Crystal ball look?

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

We painted all drywall surfaces twice. It was necessary. The paint was Sto color In, either RAL 9010 or off-white tinted. There was no other way. Once is never enough, no matter what is bought.
