Painting an area in the correct order will save time and money.
Start with the ceiling (1) walls (2) doors (3) windows (4) and finally, paint the baseboard (5).
If the finishing is done with wallpaper, then the paint job must be completed first.
Rollers are ideal for large areas, such as walls or ceilings.
Good quality rollers have a merino wool or mohair cylinder that is easily removed to be cleaned. Long hair rollers are generally used on rough surfaces, and short-haired or synthetic foam rollers are used on smooth surfaces.

Some types of cylinder, for example, the alveoli cylinder, are designed to offer special effects in the paint (stained, reliefs, etc.).
Foam rollers are relatively cheap, but do not provide a very perfect finish because they can cause small air bubbles in the paint. They should only be used with water-based paints.
For the best results, always use good quality brushes. The quality of a brush has a direct effect on the quality of the finish and the ease with which the paint is controlled and applied.

A good quality brush should:
1) have soft and thick hair;
2) be securely attached to the end of the handle;
3) not lose too much hair.

The best quality brushes have long, natural hair.

We can find brushes of various sizes and colors, so it is best to inform yourself on the most suitable one for what you wish to do.
Dark bristles - generally suitable for applying solvent based paints, such as enamels, oil paints and varnishes
Gray bristles - usually suitable for applying water-based paint.
The size of the brush varies according to the area being painted.

The brushes with the rounded end are used to reach the most difficult areas such as the corners of walls and window frames, etc.
The wire end brushes are useful for hard to reach surfaces (behind radiators or pipes, for example)
The round brushes are used in both the regular and higher precision work (window frames etc.).

Choose them preferably with rounded hair at the tip.

Before using a brush for the first time, dip it in linseed oil for about eight hours or, alternatively, in water, to consolidate the hair fixation. Then, wash with soap and water.
With the use of newspaper, remove as much paint from the brush as possible. Then, soak it in water (if water-based paints were used), in NITRO CELLULOSE THINNER or another diluent best suited for the paint used, until the hair unsticks.
If necessary, brush the hair brush with a wire brush so as to remove traces of hardened paint. Wash it out with hot water and a little detergent, and rinse it out with running water. Finally, squeeze and smooth out the hair. Keep the brushes in a horizontal position, never leaving them lying on the hairs.
If, when you pick up a brush, the hairs are hardened, let the brush soak in thinner so as to soften.

After using the roller, use a newspaper to remove the excess paint. Remove the cylinder and soak it in water or CELLULOSE THINNER (or another diluent, depending on the type of paint used). Rub the hair with a detergent (Washing up liquid or an all-purpose cleaning product) and hot water, dry it out and replace the cylinder in the support bracket.

Paint cans
Keep these in a dry, slightly warm place, out of the reach of children. To avoid the formation of surface film, ensure that the lid is tightly closed, turn the can upside down and keep it in this position. When you reopen it, the film will be at the bottom and the paint will be fresh and ready to use on top.

Wash the trays, buckets and grids with an appropriate diluent after cleaning most of the paint residues with absorbent paper.

An old paint with lumps can be filtered with a pair of nylon stockings stretched over a suitable container.
