Planning a room renovation

The quality of the renovation is primarily determined by the quality of the plans and preparations that precede it. Before you start planning your time, cost and estimate the amount of materials you need, you need to define the scope of preliminary preparations and repairs. Of course, their scale depends on the age and condition of the house or flat.
In newer homes, than from the 1950s, solid protection of wooden structures should not be expected, so cracking often occurs when central heating is installed, shrinkage and warping of the wood, as a result, gaps are formed, which will need to be sealed. The good side of modern construction is the use of low-maintenance installations, like for example. plastic pipes and gutters or aluminum window frames that do not require painting.

Older homeowners face a different kind of problem. Usually solid walls favor moisture, which must be dealt with before proceeding with the renewal. Gypsum fillings of walls and ceilings crumble over time and need to be restored before applying wallpaper or painting.. Wooden construction or decorative parts are usually covered with a dozen or so layers of paint. If the paint is peeling, you'll have to scrape off all its layers. Sometimes the preparatory work takes more time than the renovation itself.

Material consumption estimation

When calculating the amount of paint needed to paint a given room, you must start by calculating all the surfaces to be painted, multiplying their length / height by their width and adding up all the results.

Also consider doors and windows when measuring wall areas, unless they occupy a significant part of a given whole. Thanks to this, you will have a small supply of paint in case the walls are unexpectedly absorptive. Wall having 1,8 m in height and 3,5 m wide, to 6,4 m2. Wanting to paint it with an emulsion of efficiency 15 m2 per 1 liter , we need to divide the area (6,4 m2) by capacity per liter (15 m2); we will then obtain the number of liters needed for one coat of paint – 0,42. It is difficult to calculate the amount of paint needed to paint the windows, is therefore assumed, that you need a small window 2 m2, on average 4 m2, a big one 5 m2. Also add a few meters for alcoves and fireplaces.

Multiply the lengths of the opposite faces by yourself, having all the alcoves.

The walls
Measure the height and width of each wall, without subtracting the area occupied by windows and doors.
Add all received results.

Door, windows and moldings
The average size of a window is approx 4 m2.
Door – from 2 do 4 m2 (from every side), including the frame and decorative moldings. Multiply the length of the skirting board by its height.
