Cracks in walls are a problem faced by many homeowners and apartment owners. These damages can have various causes, and their repair requires appropriate knowledge and skills. It is also worth noting the factors that can lead to the formation of cracks in walls. These include mechanical damage from impacts or shocks, improper loading of the building structure, and the impact of vegetation that can penetrate the wall structure with its roots. Identifying the cause will allow you to choose the right repair method, prevent the problem from recurring in the future, and better maintain the condition of the building.
Evaluation of the type and depth of cracks
Try to evaluate the shape and arrangement of the cracks, as they may indicate specific problems. For example, irregular cracks may indicate improper plastering, while straight cracks may result from building settlement. Superficial cracks can be repaired more easily and quickly, while deep cracks may require a professional to assess the structure’s condition and recommend appropriate repair measures.
Choosing the right products for the repair
When choosing products for repairing wall racks, it is also worth paying attention to their properties, such as elasticity or adhesion. A well-chosen material should be able to compensate for wall movement caused by changes in temperature or humidity, which will prevent further cracking. In addition, it is worth investing in high-quality materials that will ensure the durability of the repair and the aesthetic appearance of the wall after the work is completed. Another important step in preparing the wall for repair is to degrease it, ensuring better adhesion of the repair product. This can be done with special degreasers or preparations diluted with alcohol. In addition, it’s a good idea to protect the area around the repair site by covering the floor with protective film or paper to prevent dirt during the work.
Repairing cracks in the wall
For deep cracks, consider the use of reinforcing mesh, which, placed on the surface of the crack before applying the repair product, will further strengthen the repaired part of the wall. After applying the last layer of the repair product, it is advisable to wait the appropriate time according to the manufacturer’s recommendations to allow the material to cure properly. Before painting the repaired wall, it’s also a good idea to apply a primer to even out the absorbency of the surface and ensure better paint adhesion. For highly absorbent plasters, applying two coats of primer may be necessary. After painting, it is also worth paying attention to the room’s ventilation. By following the above tips, the repair of wall cracks can be effective and durable, and the interiors will regain their aesthetic appearance. Remember, however, that in case of more serious structural problems or doubts about the cause of the cracks, it is worth consulting a professional who will assess the situation and advise on the appropriate solution to avoid further damage to the building.
How to repair cracks in interior plaster?
Removal of loose plaster fragments requires caution to avoid damaging the wall structure or plumbing components. After removal, thoroughly clean the dust surface and check for hidden damage that may require further intervention. For larger cavities, it is worth considering a full repair of the plaster in the area and possible reinforcement of the wall structure. Choosing the right products for the repair is crucial – a specialist will help determine a crack-resistant plaster and possibly suggest the use of reinforcing mesh for additional reinforcement of the wall structure. It is also worth noting the vapor-permeable properties of the plasters, which will allow the walls to breathe and prevent moisture buildup.
