How Do I Know When Re-plastering Is Better Than Patching a Cracked wall?

Have you ever looked at the cracks in your walls and wondered whether a simple patch is all that’s needed or if it’s time for replastering? Of course, cracked walls are a common affair in most Indian homes, but how these are dealt with might make a world of difference in the long-term life of the space. Sometimes, a quick patch job is enough, but there are situations where replastering might be the better option for the long run. We break it down for you in this blog, step-by-step: causes, solutions, and preventive measures on how to know when to patch or replaster.

Key to Understanding: Common Causes of Cracked Walls

Before one decides between patching or replastering, it is key to know the reason why the crack has appeared in the first place. Common causes of cracks in walls:

  • Structural Movement: Most buildings face some form of settlement into the ground over time. This may lead to some shifts resulting in cracks. The process is usually even, but sometimes it can be so uneven that hairline cracks might appear or much larger structural problems could develop.

  • Temperature Fluctuations: Building materials expand and contract due to temperature changes. These usual movements eventually lead to wall cracking in both plaster and concrete walls.

  • Moisture and Water Damage: Leaking water or bad waterproofing can enable the passage of water through walls, in turn weakening the plaster and causing cracks. It generally becomes more common in areas with high humidity or during the monsoon season.

  • Poor Construction Practices: At times, the cracks are due to substandard building materials or improper plastering techniques used in construction.

The nature of wall cracks helps determine their root cause and whether they need a simple patch or complete replastering.

Identifying the Problem: When to Patch vs. When to Replaster

Understanding the difference between patching and replastering is crucial. Here’s how you can determine whether a cracked wall can be patched or needs to be replastered:

  • Size and Type of Crack:

    • Small Hairline Cracks: If a crack is small and superficial, probably it can be repaired with the help of a few simple steps to patch it up, like using crack filler or plaster.

  • Larger or Deep Cracks: When cracks are larger, deeper, or go all the way through many coats of plaster, patching might not do the trick. In such a case, it is recommended that the entire wall or section be re-plastered, so as to maintain durability.

    • Extent of Damage:
    • Localized Damage: If the damage is in just a small section, patching can be quick and cheap.

    • Widespread Damage: When the damage is in large parts of the wall or more than one wall, it is best to replaster for the same consistency in results and structural strength.

    • Cracks in Concrete vs. Plaster:
    • Concrete Walls: For concrete walls, especially with related structural issues, one has to consider taking professional advice to evaluate if it’s an extent of damage that would require plastering services or the repairs run into a more extensive order.

  • Plaster Walls: Most cracks on plaster walls may be fixed using waterproof plaster for walls, but if moisture is your big concern, the extensive damage might need replastering.

Small cracks are usually patchable, but larger or deeper cracks may require the entire area to be replastered in order to ensure the longevity of the repair. I have shared how to calculate plastering quantity. In case If you are interested to know about it, you should take a look at the post.

When to Replaster Ceilings and Walls?

As with any repair, whether or not to replaster your ceilings and walls will depend on several factors including the extent of damage, age of the plaster, and the condition of the overall surface. Replaster ceilings is a more extensive repair process compared to patching and is needed when the plaster is too damaged for small fixes to be effective.This is when you have to understand that this will actually be the best alternative for your home. Now let us see when this is:

        1.Widespread Cracks

When you notice many cracks in your walls or ceilings, some of them large or deep, you may find that a full replastering of the whole area works better rather than patching up small affected areas.

  1. Aging Plaster
    Plaster naturally degrades over time. If your home is older and the plaster is cracking, crumbling, or falling off in chunks, it may be time for replastering. This is common in older Indian homes where plaster hasn’t been maintained for decades.

  1. Water Damage
    Water damage is a very serious issue that weakens plaster. If moisture has found its way onto the walls or ceilings through leaks, ineffective waterproofing, or poor drainage, plastering should be done after the underlying problem is solved. A professional service like Clean Fanatics can identify the root cause, and make structural reinforcements.

How Do I Know When Re-plastering Is Better Than Patching a Cracked wall?

  1. Structural Problems
    Sometimes, the reason behind a wall or ceiling crack could be a more significant underlying structural issue. If you notice horizontal or diagonal cracks, or cracks forming near windows and door frames, do get professional advice. If the structure is sound but the plaster is damaged, then first option works very well.

  2. Multiple Patches
    If your walls or ceilings have been patched multiple times and the surface looks uneven, it’s often better to replaster. Over time, patches can create an uneven, bumpy surface that only full replastering can fix.

  3.  Smaller cracks or other damage could be a good candidate for patching, while larger cracks or wider areas of devastation are best attended to with replastering.

Process of Re-plastering a Wall

Replastering a wall involves several steps, requiring skill and expertise to ensure a smooth, long-lasting finish. Here’s an outline of the process followed by a professional plasterer:

1. Inspection and Preparation
  • Initial Assessment: A professional starts by inspecting the wall to determine the extent of damage, whether it’s due to moisture, cracks, or general wear and tear.

  • Wall Cleaning: The surface is cleaned to remove dust, debris, and any loose plaster. This ensures that the new plaster will adhere properly.

  • Removing Old or Damaged Plaster: Any crumbling or damaged plaster is chipped away carefully, ensuring a solid base for the new plaster.

2. Applying a Bonding Agent
  • Bonding the Surface: If the underlying surface is concrete or an old plastered wall, a bonding agent is applied. This adhesive layer helps the new plaster stick more effectively to the wall.

  • Allow Time to Set: The bonding agent is left to dry or partially cure, depending on the product instructions.

3. Mixing the Plaster
  • Preparing the Plaster: The plaster mix is prepared according to the manufacturer’s instructions, ensuring the correct consistency. It needs to be smooth and free of lumps.

  • Tools Used: Professionals typically use a mixing paddle, hawk, and trowel to mix and apply the plaster.

4. First Coat Application (Base Coat)
  • Base Layer Application: The first layer of plaster, known as the base coat, is applied using a trowel. The plasterer spreads it evenly across the wall, covering any imperfections.

  • Creating a Key: Once the base coat is applied, the surface is scored lightly with a comb-like tool to create a key (grooves). This helps the second layer adhere properly.

  • Drying Time: The base coat is left to dry, which may take 24-48 hours depending on humidity and temperature.

5. Second Coat Application (Finish Coat)
  • Applying the Finish Layer: A thinner, smoother layer of plaster is applied over the dried base coat. The professional ensures a seamless, even surface, smoothing out any ridges or bumps.

  • Smoothing the Surface: The finish coat is carefully smoothed using a trowel to achieve a flawless surface.

6. Final Smoothing and Polishing
  • Final Touches: After the plaster has set slightly, a damp sponge or clean trowel is used to smooth out any remaining imperfections. This step is essential for achieving a professional finish.

  • Drying: The final coat is left to dry completely, which can take several days depending on the environment.

7. Painting or Decorating
  • Priming the Surface: Once the plaster has dried, it is ready for painting or decorating. A primer is typically applied before painting to ensure that the plaster absorbs the paint evenly.

  • Painting: After priming, the wall is painted or finished as desired.

How challenging is Re-plastering?

It can be a fairly demanding job, particularly if you are tasked with restoring the walls and ceilings of older buildings that have been badly damaged. An art on its own, plastering requires a steady hand and material knowledge, but it escalates  further with the introduction of the pre-surface preparation and managing uneven or cracked walls—all this while achieving a smooth finish.

Some reasons why re-plastering is tougher are as follows:

  1. Surface Preparation: Plastering is not a case of filling up small cracks; it entails the removal of all defective old plaster, which is messy and time-consuming. It is necessary to make sure that the surface is clean, dry, and prepared for new plaster to be applied.

  2. Skill Level Required: It requires some practice in gaining mastery over how to achieve smoothness and evenness in the application of plaster throughout a complete wall or ceiling. For homeowners not experienced in plastering, this is difficult to achieve without ending up with slight bumps and blemishes.

  3. Cracks in the Walls: If there are deep or structural cracks in your walls, simple patching is not sufficient. It’s essential to correct these cracks properly by professional wall crack repair and replastering to make a lasting fix.

  4. Moisture Problems: If the old plaster failed because of moisture problems, you will want to correct the issue that caused the damage. Waterproof plastering on walls means that when you install new plastering, there is no way moisture will get to it.

Although plastering takes more time and effort and is more technical compared with patching, this is the key procedure for a perfect-looking and durable finish. Plastering services relatively save time and take care of the right work in case you are not experienced. Today, contact Clean Fanatics for expert help in replastering and crack filling!

Prevention: How to Avoid Future Wall Cracks

Once repairs are done, what is most important is to do the following prevention measures to avoid future cracks. Here are some tips to keep your walls in great condition:

  • Moisture Issues: Tackle all problems of moisture in the house, especially in areas that can easily be attacked by water, like bathrooms or exterior walls.

  • Regular Maintenance: Keep inspecting your walls periodically for the appearance of new cracks. Early detection can save you from incurring huge repair costs.

  • Temperature Control: Maintaining stable indoor temperatures will help in reducing the expansion and contraction of building materials, which in effect will reduce the chance of cracks.

  • Professionals: Ensure that if you are adding new sections or remodeling, hire professionals who know well about good materials and techniques. This is very necessary for plastering services since it has to be done right the first time—preventing cracks is easier than fixing them.

With regular maintenance, waterproofing, and temperature control, your walls can be kept free from cracks for a longer period.
