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?

Are we talking about interior or exterior?

Interior: Buy a good dispersion paint, that will provide good coverage. If you’re a DIY store customer: for example, Renovo Meisterweiss available at HAGE BAU, which is a high-quality Brillux paint under a different brand.

Exterior: weather-exposed side. Sto Color Silco is good. It provides excellent coverage, water beads nicely, and it doesn’t get dirty easily. I used it on my garage with great results. Our house is painted with a Weber silicone paint, also good. I just don’t remember the name, only the yellow buckets. Karsten

Hello Nordlys,
I completely forgot—of course, I meant indoors. Yes, I have been/am a home improvement store customer, but I do take good advice. As in this case, I wanted to do better and avoid painting three times in the corners. So far, I have always used Alp... paint. Now, from reading other posts, I have learned that using a primer might also be an option.

You don’t need a primer. Really, you don’t.
By the way, it’s common for amateurs to apply paint too thinly when brushing or rolling. The roller really needs to be loaded well.

And don’t press too hard. Maybe you also used a bad roller?

Hello Nordlys and Caspar2020,
last question (I hope), I cautiously moved the cabinet aside and, to my horror, discovered mold spots. However, they were dry and there was no visible mold growth. Do I need to do anything besides removing the mold?

Mold remover. Dilute Danklorix one to five with water and apply with a brush. In the future, leave a bit more space between the cabinet and the wall. This often occurs on exterior walls.
