1. I ask myself the right questions to painting a wall
You do not paint your walls on a whim, so before starting your work, keep in mind the result you want to get: the finish, the appearance, the colour… all these elements will determine the technique as well as the types of products you will be using.
Try to harmoniously use colours and their shades. If that scares you, or if your rooms aren’t bright enough, go for an off-white. This shade will bring you all the luminosity of white and will bring additional warmth. Remember that light shades tend to enlarge the space.
You can choose a uniform, opaque colour or matte, glossy satin paint. The more daring may try their hand at patina, another technique that will bring a certain authenticity to your interior and depth to your walls.
2. I prepare my site for painting a wall
To paint a wall or room effectively, we recommend it to you get rid of everything in it. Otherwise, you can group all of your furniture in the centre of the room to free up as much space as possible.
Before you begin, protect your floor (and your furniture) with a tarp and then mask with adhesive tape. You can protect your floors, furniture, and windows using ScotchBlue tarp. To continue, ScotchBlue Perfect Finishes Masking Tape is very effective in protecting ceilings, baseboards, doors and windows but also in obtaining very precise paint lines. This is ideal if you want a very trendy two-tone wall or a geometric painting, for example!
Apply the tape little by little without pulling on it. Smooth the edges of the Scotch blue Perfect Finish masking tape as you apply it with your fingers so it adheres well. You can even use a smooth edge tool.
Leave on for 30 to 60 minutes before starting to paint. To remove Scotch blue masking tape after the paint has dried, it’s very easy! Just pull gently at a 45 ° angle. The ribbon does not tear, does not damage the support and can be removed without a trace. You will get a perfect result, with straight paint lines and without smudging.
3. I prepare my wall for painting
The walls must be clean, smooth and very dry.
Start by washing all the surfaces to be painted before rinsing and drying them. If your wall has small imperfections, fill in the holes and cracks with a specific coating. Once the plaster is dry, sand with sandpaper to smooth.
- If it covers your wall with wallpaper, there are not 36 solutions, you have to peel it off. The best thing is to buy or rent a stripper. As you peel off the wallpaper, scrape the wall well with a spatula to remove anything that isn’t holding up well. Then coat the surface, sand and paint!
- If it covers your wall with old paint, you can:
- Use sandpaper and sand the places that are either cracked or have holes (because this is where you will need to make the plaster).
- Cover the surfaces to be coated with glycerol paint, matt and diluted. (A next layer will get rid of the fat.)
- If you have filled the wall with plaster, wait until the plaster is completely dry, otherwise, your plaster will crumble, then paint these areas with acrylic paint before applying the plaster.
Once your wall is smooth, sand it with a thin sheet of glass. You can sand the entire wall or limit yourself to imperfect areas.
Inhaling dust is harmful to your health, so don’t forget to wear your mask.
4. I apply an undercoat
With the wall well prepared, apply an undercoat. This primer coat allows your paint to hold better and be more resistant.
We recommend it in the following cases:
- To paint a new wall.
- If you have repaired holes and cracks in the wall.
- If the wall is shiny.
- Also, if you paint over a darker colour.
5. I paint in a precise order
Start by clearing the angles, the contours and edges of the wall with your rechampir brush then with a roller. Do not make too large a trim (you might see the brush marks!).
Always apply the paint from top to bottom and paint in areas of 1m² in two crossed passes vertical, horizontal and a final vertical smoothing pass. So the paint will be well distributed and you will not have roller marks!
Let the first coat dry well, then apply a second if necessary.
When the last coat is complete, remove the ScotchBlue ™ adhesive. And admire your new clean painted walls and your new decor!
