Our Step-by-Step Process to Prepping Walls for Painting

Tools and Materials Needed

Before starting, we make it a habit to gather all our materials and supplies so we can efficiently finish your project:

  • Wallpaper removal tools: Scraper, wallpaper steamer, or wallpaper removal solution
  • Cleaning solutions: TSP (trisodium phosphate) or a vinegar and water mixture
  • Sandpaper: Medium and fine grit
  • Wall primer: High-quality options – like Kilz
  • Spackling compound: For patching holes and cracks
  • Paintbrushes and rollers: For applying primer and paint

Having these items on hand streamline the process.

Step 1: Removing Wallpaper

We start by removing the wallpaper. Depending on the type of wallpaper and adhesive used, a scraper, steamer, or wallpaper removal solution may be needed. We will apply the removal solution or steam to loosen the adhesive, then carefully scrape off the wallpaper. Patience is key during this step to avoid damaging the underlying wall.

Step 2: Cleaning Walls After Removing Wallpaper

After removing the wallpaper, adhesive residue will likely remain. This step ensures your walls are clean and ready for the next stages.

  • How to clean walls after removing wallpaper: We will mix a solution of TSP or vinegar and water. Use a sponge to scrub the walls, removing all traces of wallpaper paste. then we rinse with clean water and allow the walls to dry completely.

Step 3: Repairing and Smoothing Walls

Removing wallpaper can reveal cracks, holes, and uneven surfaces that need attention.

  • Patching holes and cracks: Using a spackling compound, we will fill in any holes or cracks by applying a spackle with a putty knife, smoothing it out, and letting it dry.
  • Sanding walls: Once the spackle is dry, we sand the walls with medium-grit sandpaper, followed by fine-grit paper for a smooth finish. This step is crucial for creating a perfect surface for painting.

Step 4: Applying Primer

Priming is essential for ensuring the paint adheres properly and helps to hide any imperfections.

  • Do you need to prime walls after removing wallpaper?: Priming helps to seal the wall and provides a uniform base for the paint.
  • Best primers to use after removing wallpaper: High-quality primers like Kilz work well. We apply the primer evenly with a roller and use a brush for edges and corners then allow it to dry completely before painting.

Step 5: Skim Coating (If Necessary)

Sometimes, even after sanding, walls may need an extra layer to smooth out imperfections. This is where skim coating comes in.

  • Cost to skim coat walls after removing wallpaper: Skim coating can be a bit pricier, but it is worth it for a flawless finish. You can DIY or hire a professional depending on your budget.
  • How to apply a skim coat: Spread a thin layer of joint compound over the wall using a trowel. Smooth it out and let it dry, then sand it lightly for a smooth surface.

Common Challenges and Solutions

Dealing with Stubborn Adhesive Residue

For stubborn adhesive that refuses to budge, products like Goo Gone or a mixture of warm water and dish soap can help break down the residue. We make sure to scrub gently with a sponge or cloth until the adhesive is gone.

Addressing Surface Imperfections

Surface imperfections that are too minor for spackling but still noticeable can often be resolved with sanding. If not, a second skim coat might be necessary but rest assured we will make sure your walls are nice and smooth before painting.

Ensuring Proper Paint Adhesion

To ensure your paint adheres well and lasts long, we make sure your walls are completely clean, dry, and primed. Proper wall preparation makes all the difference in the final outcome.

Additional Tips for Best Results

Choosing the Right Paint

When it comes to painting walls that were previously wallpapered, selecting the right type of paint is very important to achieving a smooth and durable finish.

Best types of paint for previously wallpapered walls:

  1. Latex Paint: This is a popular choice due to its durability and ease of cleaning. Latex paint is also less likely to show brush strokes and is more resistant to moisture.
  2. Acrylic Paint: Known for its strong adhesion properties, acrylic paint is excellent for surfaces that might have slight imperfections.
  3. Primer and Paint in One: These combination products can save time and effort by providing both a primer and a topcoat in one application. They work well for walls that are already in good condition.

Tips for selecting the right paint finish:

  1. Matte Finish: Ideal for hiding imperfections but can be less durable and harder to clean.
  2. Eggshell Finish: Offers a slight sheen and is more washable than a matte finish, making it a good middle-ground option.
  3. Satin Finish: Provides a smooth, velvety look with better durability and washability, suitable for high-traffic areas.
  4. Semi-Gloss and Gloss Finishes: Highly durable and easy to clean, these finishes are best for areas that require frequent cleaning, such as kitchens and bathrooms.

Painting Techniques

Achieving a professional finish involves more than just choosing the right paint; it’s also about how our team applies it.

Our best practices for painting your prepared walls:

  1. Use High-Quality Tools: At Let’s Upgrade Painting we always invest in good-quality brushes and rollers. A high-quality roller will distribute paint more evenly and cover more area, while a good brush will handle edges and corners with precision.
  2. Apply Even Coats: It’s important that we don’t overload a brush or roller with paint. Instead, we focus on applying smooth, even coats, allowing each to dry completely before applying the next. This helps prevent drips and ensures a smooth finish.
  3. Work in Sections: We Paint one section of the wall at a time, usually about a 3×3 foot area. This approach helps to maintain a wet edge and avoid visible lines where one section dries before rolling the next.

Tools and methods we use for a professional finish:

  1. Roller Techniques: A ‘W’ or ‘M’ motion with the roller helps to distribute paint evenly and reduce streaks. This technique helps cover the surface more effectively as well.
  2. Cutting In: Using an angled brush to ‘cut in’ around the edges of walls, ceilings, and trim before using the roller. This creates clean lines and ensures that these areas receive adequate paint coverage.
  3. Feathering: Feather out the edges of our brush strokes or roller marks to blend seamlessly with the rest of the wall. This technique is especially important when working with glossy or semi-gloss finishes.

Maintenance After Painting

Once your walls are beautifully painted, proper maintenance is key to keeping them looking fresh and vibrant for years to come.

How to care for newly painted walls:

  1. Allow Proper Drying Time: Make sure the paint has completely cured before subjecting the walls to regular use. This can take anywhere from a few days to a couple of weeks, depending on the paint type and environmental conditions.
  2. Regular Cleaning: Dust your walls regularly to prevent dirt buildup. For more thorough cleaning, use a soft cloth or sponge with mild soapy water. Avoid abrasive cleaners that can damage the paint.

Tips for maintaining a fresh look:

  1. Touch-Up Paint: Keep some leftover paint for touch-ups. Minor nicks and scratches can be easily fixed with a small brush and a bit of paint.
  2. Avoid Excess Moisture: In areas prone to humidity, such as bathrooms, use exhaust fans to reduce moisture levels. This helps prevent mold and mildew growth, which can damage the paint.
  3. Inspect Regularly: Periodically check your walls for signs of damage or wear. Addressing small issues promptly can prevent them from becoming larger problems.
