Walls are the backdrop of every home or office space. They set the mood of a room, enhance its design, and provide the canvas for colour, decor, and lighting. But even the most beautifully painted wall can look dull if its surface isn’t smooth. That’s where skim coating steps in. By applying a thin, even layer over rough or cracked areas, skim coating helps transform ordinary walls into flawless surfaces ready for finishing. Whether you are building a new apartment or want to renovate your office building, skim coating is the most effective solution for elevating the interior and durability of walls.
But still, most people find investing in skim coating a worthless thing, so if you are also one of those, then this blog is just for you. Here we will explore what skim coating is, why it matters, and how pairing it with the best quality putty can make your walls stronger, smoother, and longer-lasting.
What Is Skim Coating?
Skim coating is the process of spreading a thin layer of plaster or joint compound over walls or ceilings to repair or smooth out imperfections. Think of it as a makeover for your walls. When you skim coat plaster walls, you cover cracks, dents, holes, or uneven textures with a smooth finish that looks brand new.
Unlike thick layers of plaster, skim coats are applied thinly, often just a few millimetres. The goal is not to rebuild a wall but to refine it, giving it the right texture and strength for further treatments like putty, primer, and paint.
Why Do Walls Need Skim Coating?
Walls go through a lot. Over time, they develop cracks from settling, scratches from furniture, or stains from moisture. These flaws might look small, but they can make paint appear patchy and unprofessional.
Skim coating offers a solution by:
- Hiding imperfections: Small cracks and bumps disappear under the thin layer.
- Creating uniformity: It levels out rough surfaces and mismatched textures.
- Preparing for finishing: Paint and putty adhere better to even, smooth surfaces.
- Improving durability: A well-coated wall resists peeling and cracking in the future.
When you combine skim coating with the best quality putty, you get both beauty and strength. The walls not only look flawless but also hold up better against moisture, dust, and general wear.
The Role of Wall Putty After Skim Coating
Once the skim coat dries, the next step is applying wall putty. Putty is a fine, cement- or acrylic-based powder that, when mixed with water, forms a paste. This paste is spread over the skim-coated surface to give walls an extra-smooth, polished finish.
Choosing the best quality putty is important because:
- It enhances paint adhesion, making colors look brighter and more even.
- It strengthens the wall surface, reducing the chances of flaking or chipping.
- It improves resistance to moisture, which protects against dampness and mold.
- It ensures long-term results, reducing the need for frequent repainting.
Together, skim coating and putty form a two-step process that prepares walls for their best possible finish.
Benefits of Skim Coating Before Putty Application
1. Smoother Walls
The main benefit of skim coating is smoothness. Uneven walls can ruin even the most expensive paint job. By choosing to skim coat plaster walls, you eliminate rough patches and give the putty a consistent base.
2. Better Adhesion
Putty and paint adhere much better to a skim-coated surface. Without it, walls may soak in too much product or fail to bond evenly. This leads to a patchy appearance and weaker durability.
3. Longer Paint Life
When walls are well-prepared, paint not only looks better but also lasts longer. Skim coating ensures that walls don’t peel, crack, or absorb excess moisture that could otherwise shorten paint life.
4. Cost-Effectiveness
Although skim coating adds an extra step, it saves money in the long run. Proper preparation reduces the need for repeated painting or costly wall repairs.
5. Aesthetic Perfection
The goal of wall finishing isn’t just durability but also beauty. Skim coating gives your walls the kind of sleek finish that enhances the overall look of your interiors.
Step-by-Step Process of Skim Coating and Putty Application
Here’s a simple breakdown of how skim coating and putty work together to give your walls a flawless finish:
Surface Preparation
Clean the wall thoroughly by removing dust, dirt, or loose paint.
Apply Skim Coat
Spread a thin layer of plaster over the wall using a trowel or roller. Ensure it covers cracks, holes, and bumps.
Drying Time
Allow the skim coat to dry fully. Depending on humidity, this can take several hours.
Light Sanding
Sand the dried skim coat lightly to remove minor ridges or unevenness.
Mix Wall Putty
Combine the best quality putty with clean water to form a smooth paste.
Apply Putty in Layers
Spread the first layer evenly and let it dry before applying the second. Each layer should be thin and even.
Final Sanding and Finishing
After drying, sand the surface gently to achieve a polished finish, ready for primer and paint.
Tips for Getting the Best Results
- Choose the right putty: Not all putties are the same. Cement-based options are strong and durable, while acrylic putties provide a smooth, quick-drying finish.
- Don’t skip drying time: Each layer, whether skim coat or putty, needs adequate drying time. Rushing can cause cracks or poor adhesion.
- Use clean tools and water: Impurities can weaken the mixture or leave marks on the wall.
- Apply thin layers: Thick layers can crack. It’s better to apply two thin coats than one thick one.
- Sand carefully: Sanding helps achieve the perfect finish, but it should be done gently to avoid scratches.
