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?

On what kind of surface did you paint? Have you calculated how much paint you used per square meter?Renovation fleece/ old paint layers with some problematic shades (light blue) as well as newly plastered electrical installations.
Lastly, gray drywall on the attic ceiling.
Whenever there were transitions (light/dark), we used a primer.
We calculated all the surface areas beforehand and estimated consumption at 6 sqm per liter (64.6 sqft per gallon) plus an additional 10% reserve. For premixed paints, if we were running low, we ordered the next larger bucket.
In fact, we ended up with quite a bit of paint left over.
What I think was even more important was having a good set of rollers and brushes from a professional painter’s supplier (not comparable to the stuff from the hardware store), as well as sturdy roller handle extensions made of aluminum.
Since we worked a lot with painted edges in the areas, we used Storch’s purple tape.
The Bosch PLL 360 was also helpful (best when mounted on a studio light tripod) for masking.

We ended up wallpapering it with new fleece wallpaper, then skim-coated it to match the existing walls, and finally painted the area and surroundings with the leftover paint we had stored in the basement (it was still in good condition).
No one can tell that it was renovated. Even the white on white doesn’t stand out.

Masking tape does not need to be purple or blue on the inside; yellow is sufficient since UV resistance is not important indoors. Brands like Tesa, 3M, Storch, Kipp—they all work fine. It’s not rocket science.
For primer paint, when using white, the cheap paint from the bottom shelf works very well for priming. As mentioned, it is good for the first coat; a second coat with a branded product will provide full coverage and an even finish. Please never forget to impregnate new walls with a deep primer—here, the cheapest one is also fine. We filled it into a garden sprayer and sprayed all walls and ceilings, including drywall, after filling. This prevents the substrate from absorbing paint unevenly, so the final paint finish is uniform rather than patchy. K.
