Tired of your home decor? Changing the environment easily, quickly and cheaply is something that can be achieved simply by changing the color of the walls. And yes, painting a wall can be a lot easier than it looks. We have prepared a step-by-step guide with tips to perform this activity more conveniently and without errors.

Materials

Before you get your hands on the paint, be aware that you will need a few items. We list the materials needed for you to program:

  • Wall sandpaper (medium and fine);
  • Low-pile wool roller;
  • Medium brush;
  • Ink tray;
  • Spatula;
  • paint mixer;
  • crepe tape;
  • Sealer;
  • Ink;
  • Spackle (if there are imperfections or holes);
  • Paper or plastic to cover the floor;
  • Canvas;
  • Staircase.

Prepare the space

You want to paint the wall, not the floor or objects, don’t you? So, before starting to paint, prepare the space. Reposition furniture and objects in the environment in order to free the surface to be painted and keep them away from it, to avoid dirt. A good tip is to group furniture and space objects and cover them with a canvas.

Then cover the floor with paper or plastic and, with masking tape, protect baseboards, switches and sockets, leaving only the wall you want to paint-free.

Prepare the wall

With the environment protected and free, it’s time to prepare the wall to be painted. Check the wall for any imperfections or holes. If so, apply a spatula using a spatula to form a smooth plane.

If there are no imperfections, or right after adjusting them, sand the wall to level it and prevent excess plaster from remaining. If the wall in question has a firm surface with little plaster, use finer sandpaper (220 or 240); if there is a bigger and coarser unevenness, use coarser sandpaper (80 or 100). It is important to sand the entire wall that will be painted.

If you don’t have an electric sander and are going to do this step manually, a good tip is to fold the sandpaper into two or four parts and make a circular motion on the wall.

After sanding, wipe with a damp cloth to remove dust. Cleaning is essential so the ink can be applied evenly.

Before applying the first coat of paint on the wall, it is recommended to apply a sealer, which serves as a preparatory layer for the paint. It evens out the wall and prevents stains from appearing when applying paint. The sealer must be applied with a wool roller over the entire surface to be painted.

Paint the wall

Now, yes, it’s time to paint the wall. Place the paint (or the mixture, if the manufacturer indicates to dilute the paint in a little water) in the tray and use the wool roller for application. Avoid soaking the roller and use the tray to remove excess.

A useful tip is to start painting the wall from top to bottom, in vertical stripes, the width that is comfortable for you and suitable for the size of the roller.

In most cases, it is necessary to apply a second coat of paint. It is recommended that this new application be done at least four hours after the first application.

To paint the corners and proximity of elements such as baseboards and switches, use a medium brush, so you’ll have more precision and reach more delicate places.

If the wall to be painted has old paint, it is important to remove this layer before applying the new paint. Sand the wall until it is even and suitable for repainting.

How to paint textured wall

If the wall you intend to paint has any texture, special care is needed. The step-by-step must be followed, but what changes are the forms of application.

You can apply the paint with either a wool roller or a brush. If you prefer the brush, choose one with soft, wide bristles. Paint diagonally, one hand in one direction and the other in the opposite direction, to cover the entire textured wall. The tip, in this case, is to be patient and change the direction when applying.

Finalization

After applying the last coat of paint, remove all the masking tape, before it dries completely, to prevent it from peeling or breaking in any corner.

Wash all used material under running water when the paint is still fresh and dry it well before storing.

Wait at least four hours for the paint to dry, then arrange the furniture and objects in the room in the place.

Painting the wall can be easy and fun

With the step-by-step in hand, just choose the color and type of paint you want to use in the space. Put on some clothes that you can get dirty, some music to play and give the first brushstroke.
