Duration / Effort of own contributions?

Hello everyone,

to better estimate my own work efforts in house construction, I would appreciate your "guidelines" regarding the effort and duration.
Please estimate how long the following tasks approximately take - considering that two people are working together (skill level "rather inexperienced"):

[*]Laying click vinyl on about 80 sqm on one floor?
[*]Insulation between rafters in the attic (area without dormer windows) - usable floor area of the floor is about 120 sqm (I cannot currently provide the sqm number of the gable roof area)?
[*]Sanding and painting walls (starting from gypsum Q2) on about 112 sqm of living space?

Thank you very much!

oh dear,,,,,,,,,,,,,,,

I would have assumed 5 days each... Does that work?

Nope... Never. Unless you work 24/7. Count on a good four weeks for everything. At least....

You lay 80m2 of vinyl easily and casually in 3 days. No idea about the rest...

For the vinyl, 5 days will definitely be enough. For painting, I wouldn't be sure. If 2 coats are necessary, then probably not.
