    In this blog post, we'll dive into the most common plastering problems and chat about how these skilled contractors can work their magic to fix them up like pros. Ready? Let's go!

    1. Uneven Surface

    One of the most frequent issues encountered in plastering is an uneven surface. This can occur due to improper application techniques, insufficient drying time, or structural inconsistencies. Professional plastering contractors have the experience and skills to identify the underlying cause of unevenness and employ the necessary techniques to rectify it. They may use techniques such as re-plastering, sanding, or skimming to achieve a smooth and level finish.

    2. Cracks

    Cracks can appear in plaster for various reasons, including shrinkage, movement of the building, or poor workmanship. Professional plastering contractors can assess the type and severity of the cracks to determine the best course of action. They may fill the cracks with suitable materials, reinforce the plaster with mesh or tape, or even remove and reapply the plaster if necessary. By addressing cracks promptly, contractors ensure a durable and visually appealing surface.

    3. Blistering

    Blistering refers to the formation of bubbles or bulges on the surface of the plaster. This problem can arise due to trapped moisture, inadequate ventilation, or improper mixing of materials. Skilled plastering contractors understand the causes of blistering and take steps to mitigate them. They may carefully remove the affected plaster, address the underlying issue, and reapply a fresh coat to achieve a flawless finish.

    4. Peeling

    When the plaster starts to peel off the wall, it not only looks unsightly but also compromises the structural integrity. Peeling can occur due to moisture penetration, poor adhesive properties, or improper application techniques. Professional plastering contractors will inspect the area, identify the root cause, and then remove the loose plaster. They will then reapply a suitable primer, adhesive, and plaster to ensure a long-lasting and secure finish.

    5. Discoloration

    Discoloration of plaster can be caused by a variety of factors, including water damage, mold growth, or even aging. Professional plastering contractors possess the expertise to determine the cause of discoloration and take appropriate measures to address it. They may treat the affected area with antimicrobial solutions, remove and replace the discolored plaster, or apply a fresh coat of paint to restore the desired appearance.

    6. Efflorescence

    Efflorescence refers to the appearance of white, powdery deposits on the surface of plaster. It occurs when soluble salts in the wall material dissolve in water and are subsequently carried to the surface. Professional plastering contractors can diagnose the underlying cause of efflorescence, which may include water leaks or poor moisture control. They will clean the affected area, apply a suitable sealer, and ensure proper drainage to prevent further salt deposits.

    7. Taping and Joint Problems

    Taping and joint problems often occur at the junctions between plasterboard panels. Issues like visible seams, cracking, or tape lifting can compromise the aesthetics and durability of the plaster. Professional plastering contractors possess specialized knowledge in taping and jointing techniques. They will carefully inspect the area, apply joint compound, and feather the edges to create a seamless and robust finish.

    8. Poor Adhesion

    Poor adhesion between the plaster and the underlying surface can lead to delamination, where the plaster layer separates from the wall. This problem can be caused by factors such as inadequate surface preparation, improper mixing of materials, or incompatible surfaces. Professional plastering contractors will evaluate the adhesion issues, remove the loose plaster, and ensure proper bonding by applying suitable primers or adhesive agents before re-plastering.

    9. Texture Matching

    In cases where repairs or additions are made to existing plaster, achieving a consistent texture can be challenging. Professional plastering contractors are adept at analyzing the texture and composition of the existing plaster and reproducing it accurately. Through careful blending, application techniques, and the use of appropriate tools, they can seamlessly match the texture of the repaired or added plaster with the surrounding areas.

    10. Poor Workmanship

    Sometimes, the primary issue lies in the craftsmanship of the original plastering work. Poor workmanship can lead to a range of problems, including uneven surfaces, visible joints, or weak adhesion. Professional plastering contractors possess the skills and knowledge required to rectify such issues. They will evaluate the extent of the problem, determine the best course of action, and execute the necessary repairs or reapplication of plaster to achieve a high-quality finish.

    So Give It A Fresh Start

    With the underlying problem resolved, it's time to give your walls a fresh start. Professional plastering contractors will expertly reapply the plaster, using their expertise to ensure a smooth and secure finish. They'll apply the appropriate techniques, taking into account the type of surface and the desired outcome. Whether it's a traditional smooth finish or a textured masterpiece, they'll work their magic to give your walls a new lease on life.


    Plastering is a critical step in creating beautiful and durable interior and exterior surfaces. However, problems such as uneven surfaces, cracks, blistering, and peeling can arise during the plastering process. By engaging professional plastering contractors, homeowners and builders can benefit from their expertise in diagnosing and resolving these issues effectively. With their knowledge of proper techniques, materials, and tools, plastering contractors can ensure a flawless finish that enhances the aesthetics and longevity of the plastered surfaces. So, when it comes to plastering projects, entrusting the job to skilled professionals is a wise decision.
