What do I do if I want to change the wallpaper?

Changing the wallpaper may seem like a daunting task, but with the right preparation and tools, it can be a manageable and rewarding process. Here I explain the steps to follow to change the wallpaper in your home.

Preparation

Materials and Tools Needed

Before you begin, make sure you have the following materials and tools:

• Plastic or metal spatula
• Water sprayer or wallpaper remover
• Sponges and rags
• Wallpaper scraper
• Sandpaper
• Painter's tape and drop cloths
• Wallpaper paste (if you are going to apply a new wallpaper)
• General purpose knife

Protection of the Work Area

Protect your floors and furniture with drop cloths and painter's tape. This will prevent damage and make cleaning easier.

Removing Old Wallpaper

Soaking and Scraping Method

1. Paper Perforation: Use a paper punch tool to make small holes in the surface of the wallpaper. This will allow water to penetrate more easily.
2. Water or Remover Application: Fill a sprayer with hot water or a mixture of water and a commercial wallpaper remover. Generously spray the wallpaper, ensuring it is thoroughly soaked.
3. Wait and Stir: Let the water absorb for about 15-20 minutes. Once the paper is well saturated, use a putty knife to scrape the paper from the wall. Work in small sections to make the process easier.

Steam Method

1. Rental of a Wallpaper Steamer: You can rent a wallpaper steamer at most home improvement stores.
2. Steam Application: Fill the steamer with water and turn it on. Place the steam plate on the wallpaper and let it act for about 30 seconds.
3. Paper Scraping: Use a spatula to scrape the paper after applying steam. This method is especially useful for wallpapers.

Wall Preparation

Cleaning and Repair

After removing the wallpaper, clean the wall with a sponge and warm water to remove any glue residue. If you find imperfections, use sandpaper to smooth the surface. Apply filler to the cracks or holes and sand again once it is dry.

Primer

Apply a primer coat to prepare the wall for the new wallpaper. The primer ensures better adhesion and a smoother finish.

Installing the New Wallpaper

Cutting and Application

Cut the new wallpaper to size, leaving a little margin at the top and bottom for adjustments. Apply wallpaper paste to the back of the paper (or on the wall if you are using wallpaper) and place it on the wall, smoothing it from the center out to the edges to eliminate air bubbles.

Pattern Alignment

If the wallpaper has a pattern, make sure to align it correctly between the strips to maintain visual continuity. Use a spatula or a rubber squeegee to smooth the paper and ensure good adhesion.

Excess Trimming

Use a utility knife to trim excess paper at the edges and around switches or outlets. Place the edges carefully and press to ensure they are well adhered.

Changing the wallpaper can completely transform a room, giving it a new feel and freshness. By following these steps and with a little patience, you can effectively renew the walls of your home. Remember that the key is in the preparation and in using the right tools for each phase of the process.
