ᐅ Quantity Surveying for Paint and Wallpaper

Hello everyone.

We are about to buy a house.

All wall wallpapers and wooden panels are to be removed, and a woodchip or textured wallpaper will be applied. It is a residential building with approximately 135 m² (1453 sq ft) of living space, plus a basement of about 75 m² (807 sq ft), which also needs the renovation mentioned above.

Now to my questions:

How many liters of paint should I roughly calculate?
How many rolls of wallpaper should I roughly calculate?
Is there a calculation formula?

Can someone help me?

Thanks in advance!

Hi,

Paint is relatively straightforward. The containers indicate how many square meters you can cover with them. However, I would recommend adding at least 10% to the calculated area since I was never quite able to finish with the exact amount and always needed a little more.

Wallpaper is a bit more complicated because you have fixed widths for the strips. If you have Excel, I can send you a file. Otherwise, here is an example without taking windows or doors into account:

Room height 2.60m (8.5 ft)
Room length 5.20m (17 ft)
Room width 4.00m (13 ft)

Roll length 10.05m (33 ft)
Roll width 0.53m (1.7 ft)

Number of strips: (Room length × 2 + Room width × 2) ÷ Roll width
This number must be rounded UP = 35 strips

Number of rolls: Number of strips ÷ (Roll length ÷ Room height) rounded DOWN
This must then be rounded UP again = 12 rolls

I hope this makes sense 🙂

135 sq m (1455 sq ft) and 75 sq m (807 sq ft), do you mean the living area or the wallpaper/paint surface? 🙂
