Start by gathering your furniture in the center of the room or, better, take it out if you can.
Protect them with tarpaulins as well as the floors and put masking tape to avoid overflowing on surfaces that should not be painted (along skirting boards, joinery, etc.).
Dismantle the covers of electrical sockets and switches and protect them.
Then wash and rinse the partitions to be painted.
Seal the wall before applying the paint
If the wall is damaged, a re-coating is necessary to fill the holes and cracks.
The professional rules provide, before coating, a coat of printing (also called undercoat or primer), to ensure that the coating will hold well, then a new coat of printing before the two finishes.
The underlay is often overlooked.
However, it is essential for a beautiful result, especially if the wall has never been painted.
Your coating must be very dry and ginned with sandpaper.
Before applying the paint, stir it with a wand, bringing the bottom to the surface.
Then pour it into a paint tray.
“Weather conditions are decisive.
Do not paint
in the middle of winter without heating
.
If it is too cold, the paint does not dry and cracks.
If it's very hot, it dries too quickly and traces of recovery appear”
, warns Fanny Michel.
A temperature between 12 and 25°C is ideal.

Prepare your tools
New brushes tend to leave hairs on surfaces.
Make fall those which hold badly by brushing them back several times, then put your brushes to soak several hours in water.
Wring them out and rub them on a rough surface or sandpaper.
Pass a sticky tape over your rolls to remove the fibers that adhere badly.
Start with the ceiling.
Clear the corners first (paint them with a special brush, called "rechampir", see below).
Load the roller evenly by rolling it over the surface of the paint then wring it out on the rack.
Work in one meter squares and cross the passes.
Finish with a vertical movement.
Do not come back on a square being dried so as not to make traces.
Remove the masking tape when the paint is still fresh to avoid chipping it, or run a utility knife over the tape and remove the cut strip.
Forget one-coat paints that rarely keep their promises.

Roller, brush: which tool to choose?
The choice of tools is very important.
The
type of roll
is selected according to the medium.
The longer the fibers, the more paint they deposit.
On a well prepared, smooth and regular wall, fibers of 10 to 14 mm allow to leave enough material.
On an irregular support, use longer fibers (20 mm).
The short ones (from 5 to 8 mm) are reserved for glossy finishes (lacquers).
The roller with tank is very heavy and quickly tires the arm.
Keep one or two
brushes
handy: a flat one for relief or surfaces not accessible to the roller, and a model to repaint with its point of longer bristles in the center.
Natural bristles are more suitable for solvent-based (oil) paints, while synthetic fibers are reserved for water-based paints.
