Removing wallpaper before HDB Painting

Are you looking to refresh your HDB flat with a vibrant new coat of paint? Whether you’ve just moved into a resale unit or want to modernize your long-time home, HDB painting is one of the most effective ways to transform your living space. Removing old wallpaper and replacing it with a smooth, freshly painted finish not only enhances the overall appearance but also improves durability and cleanliness. With professional HDB painting, you can achieve a flawless look that brings new life to your walls, making your home feel brighter, more spacious, and truly refreshed.

However, many homeowners in Singapore face a common dilemma: Should you paint over wallpaper, or must you remove it first?

At Fixlaa, we believe that the foundation of a great home makeover lies in the preparation. In this comprehensive guide, we will walk you through everything you need to know about removing wallpaper before engaging HDB painting services, ensuring your walls look flawless for years to come.

Why You Must Remove Wallpaper Before HDB Painting

It might be tempting to save time and money by painting directly over existing wallpaper. However, any professional offering Painting Services Singapore will tell you that this is a recipe for disaster. Here’s why:

1. Peeling and Bubbling

Wallpaper is held up by water-soluble adhesive. When you apply wet paint over it, the moisture can soak through the paper and reactivate the glue. This causes the wallpaper to lift, bubble, and peel away from the wall, taking your expensive new paint with it.

2. Visible Seams and Textures

Even if the wallpaper stays stuck, the seams where the paper meets will almost always show through the paint. If the wallpaper has an embossed pattern or texture, it will create an uneven, unprofessional look that ruins the aesthetic of your HDB flat.

3. Hidden Mold and Dampness

Singapore’s humid climate is a breeding ground for mold. Wallpaper can often trap moisture against the concrete walls of an HDB flat. By removing the wallpaper, you can inspect the health of your walls, treat any mold issues, and ensure a hygienic environment for your family.

4. Longevity of Results

A high-quality HDB painting job should last 5 to 10 years. Painting over wallpaper significantly shortens this lifespan. To get the best ROI on your home improvement, starting with a bare, clean wall is essential.

Step-by-Step Guide to Removing Wallpaper in Your HDB

Removing wallpaper can be a tedious task, but following a systematic approach makes it manageable.

Step 1: Preparation of the Space

Before you touch the walls, protect your flooring and furniture.

• Move furniture to the center of the room.
• Cover the floor with plastic sheets or drop cloths (canvas is better for preventing slips).
• Tape down the edges to ensure no water or paste drips onto your vinyl or parquet flooring.
• Turn off electricity to the room and cover electrical outlets with masking tape.

Step 2: Identify the Wallpaper Type

Not all wallpapers are the same.

• Strippable Wallpaper: The easiest to remove. You can usually peel it off by hand without water.
• Vinyl-Coated Wallpaper: These have a plastic layer that resists water. You will need to “score” or perforate the surface so moisture can reach the glue.
• Traditional Paper: Requires soaking with a removal solution.

Step 3: Scoring the Surface

If your wallpaper is water-resistant, use a wallpaper scoring tool. Move it in circular motions across the wall to create tiny holes. Be careful not to press too hard, as you don’t want to damage the plaster or drywall underneath.

Step 4: Applying the Removal Solution

You can use a commercial wallpaper stripper or a DIY mixture of warm water and a little dish soap or white vinegar.

• Use a sponge, spray bottle, or roller to saturate a section of the wall.
• Pro Tip: Work in small sections (about 3×3 feet). If you soak the whole room at once, the sections will dry out before you reach them.
• Let the solution sit for 10–15 minutes to soften the adhesive.

Step 5: Scraping it Away

Once the paper is soft, use a putty knife or a wallpaper scraper to gently lift the paper. Start at a seam or a perforated hole. Keep the blade at a low angle to avoid gouging the wall.

Step 6: Cleaning the Adhesive Residue

This is the most skipped step, but the most important for HDB painting. If glue residue remains, your paint will crackle or “alligator.” Use a scrub sponge and a mixture of water and TSP (Trisodium Phosphate) to wash the walls until they feel smooth and non-tacky.

Preparing the Wall for HDB Painting Services

Once the wallpaper is gone, your walls are likely in a “raw” state. Before the Painting Services Singapore team arrives, the walls need to be prepped:

1. Patching: HDB walls often have small chips or holes from the wallpaper removal process. Use a joint compound or putty to fill these gaps.

2. Sanding: Once the putty is dry, sand the walls with fine-grit sandpaper to ensure a perfectly level surface.

3. Priming (The Secret Step): After removing wallpaper, a sealer or oil-based primer is highly recommended. This “locks in” any microscopic glue residue and provides a perfect surface for the new emulsion paint to bond to.

Professional vs. DIY: Which Should You Choose?

While DIY wallpaper removal is possible, it is back-breaking work. Many Singaporeans choose to hire professional HDB painting services like Fixlaa for several reasons:

• Speed: What takes a homeowner a weekend takes a professional crew a few hours.
• Tools: Professionals use industrial steamers and specialized chemicals that make the process cleaner and more efficient.
• Quality Finish: A professional service ensures that the wall is perfectly prepped, resulting in a “showroom” finish that DIY jobs rarely achieve.
• Post-Job Cleanup: Removing wallpaper is messy. Professional services include the disposal of old paper and thorough cleaning of the site.
