1. When do we paint?

No wonder renovation work occurs when it’s a beautiful weather outside. It’s not recommended to start painting when it’s cold outside, very hot or a rainy day. Here’s why.
At low temperatures, stretching backing paint is difficult, drying is slowly and the paint can fill will dust. The temperature must not be less than 5 degrees, even after applying the paint, because the paint film isn’t done properly, compromising the quality and endurance in time.
Also, the temperature shouldn’t exceed 35 degrees when you’re painting. Avoid painting the exterior during the day when the surface is exposed directly to sunlight, because the paint dries quickly and the paint film doesn’t have time to show off the support. Also its adherence is low and it can lead to defects (traces of brush or roller, scrub etc).
Avoid painting on rainy days or with high percentage of humidity (over 70%).
2. Space and materials

Every time you paint indoors, make sure there is adequate ventilation at the working space, both for proper paint drying and avoid inhaling the vapors.
If possible empty the room of furniture and other things. If this isn’t possible, move them so as to have enough space near the wall you want to paint. Don’t forget to cover them with a plastic foil or an old piece of cloth not to sprinkle them with lime. It’s also important to cover the floor with something, like paper sheets not to dirt it. Window and door frames, outlets and switches may be covered with duct tape to protect them.
Prepare your materials in advance. It’s important when you start painting, to have all tools handy (roller, brush, palette knife, sandpaper, paper tape, plastic wrap) and necessary materials (paint, color mixing paint, plaster or putty for reparation, primer etc). You can make a list of necessary things you need to purchase them in time for when start working you no longer be interrupted for something.
3. Preparing the walls

If is necessary, prepare the walls by removing the old paint which is about to fall with a spatula with spatula. Repair holes and cracks from cracks with plaster, and if they are too deep, filled with plaster, then apply plaster coat. Next step is to polish with sandpaper the areas where repairs were made, clean the walls of dust after the repairs with a clean sweep, then proceed to the application of primer, which is designed to fix the paint on the walls. Primer is made of glue mixed with water in a proportion of 1/10. After the glue is mixed thoroughly with water, apply with a brush directly on the walls to dampen them. Then we wait between 30 to 90 minutes for the moisture to be absorbed by the walls.
4. Washable paint application

Washable paint application is made after the primer is dried. The best application of washable paint is made with a roller.
Buy quality paint, otherwise you risk not to cover well the walls and you’ll need to apply more layers.
Don’t dilute it with too much water so you can stretch great with a roller. Pour some water, mix well and try to see how the paint stretches on a small part on the wall. If it’s too diluted, you’ll have to give multiple layers and it won’t last in time.
If you prepare the color at home, don’t put all the pigment in the washable paint. Pour a little color, mix and try with a brush on the wall to see if it’s the desired color. Before start painting, mix well the color with the washable paint. Otherwise there might be a change to occur some small colored painted dots on the walls.
Don’t fill the roller with washable paint because it may drain on the floor. Use a grill to squeeze it.
You must begin with the ceiling and continue with walls, not to splash paint over them. Before you start painting the walls with a roller, paint the edges with a brush.

It’s important to paint a surface once (ex: all ceiling at once or an entire wall once) to prevent streaks of paint to dry. An elongated trace near a dry one will not be the best picture you want to see. Thus, the high walls of the rooms will be painted with a paint roller with a long stem or two-person team, not to see the connections of the paint.
If you need to paint multiple layers of washable paint, wait until the first layer has dried well.
Once you have finished painting, wash thoroughly the brush roller than you can reuse it. Don’t let the paint dry on them.
