Cracked walls often occur, even on the walls of new houses, this situation is certainly quite disturbing the view and over time it can even be dangerous. What are the types of cracks, why do they occur, and how do you deal with them? Check out our review below!
1. How to Prevent Cracked Hair Walls
The term hair crack is a term for cracks with a size below 1 mm and a branched shape. Hair cracks occur due to imperfect coating, for example when the wall is in hot conditions. Due to the heat, the plaster did not blend perfectly with the dry plaster first. The second thing that caused hair cracks was that the cement mortar used was too thin and was immediately covered again with the plaster.
The last thing the cause is the finishing paint used does not have good elasticity. To prevent this, remind the handyman to do watering on the wall until it is saturated first on the part to be treated. This watering aims to keep the wall damp and cool. In addition to watering, the surefire solution that Teman88 can do is to cover the crack with Super Cement from Aquaproof.
Super Cement is a cement quality improvement fluid based on polymer emulsions. This milky white liquid can be used as an additive (plaster, plaster, plaster), adhesive (concrete, ceramic, granite), and primer (wall, floor, metal), to cover hair cracks Super Cement from Aquaproof can be used as a primer or a coat of primer before coating the walls with waterproofing. Its application is also very easy, namely:
Mix Super Cement and cement with a volume ratio of 1: 1.25
Stir well until there are no lumps
Apply one layer using a brush or roll on the cracked part of the hair
The primary function of Super Cement and cement is to close hair cracks, bind residual dust and dirt and increase adhesion to the substrate.
2. How to Repair Cracked Walls Due to Movement of the Foundation Structure
The unstable foundation of the house due to shifting of the soil caused the bricks inside to break. The broken bricks eventually cracked the plaster and wall tiles. Cracks due to the movement of this foundation are diagonal or perpendicular.
Do not delay repair of walls with crack marks like that because if the ground moves again, the cracks will get worse. To repair it, make a small gap between the wall and the beam at the top of the wall. This is done to reduce pressure from above.
The gap can be filled with styrofoam or rubber and close the gap that has been filled with wood or gypsum trim. After that, open the cracked wall 1 cm wide and fill it with a 1:5 cement sand mixture. After being allowed to dry for three days, cover the area with a mixture of Super Cement Aquaproof with cement, then paint as usual according to the desired color.
In contrast to other cement additive products, Super Cement Aquaproof is formulated with Bond Booster Technology so that it will provide long-lasting and lasting results. In addition, Super Cement Aquaproof products can also prevent repeated cracks. On the other hand, this liquid can also completely close the gap due to cracks and has low shrinkage.
3. How to Repair Cracked Walls Due to Different Materials
These cracks are caused by differences in the use of wall materials, such as masonry and concrete surfaces covered in one plaster. To overcome this type of cracking is to make a dilatation or cavity between the two surfaces of the material. The cavity resulting from the dilation is filled with rubber sealant, iron strip, or fiber glass, as reinforcement. Make sure the bonding strength of the masonry species at the corners of the wall meeting is really strong, because in these places it is very prone to cracking.
The same is the case if you experience material differences due to the connection of new materials and old materials, for example in the connection of concrete castings. At the joints of old concrete and new concrete need to be glued with a mixture of Super Cement and cement by applying it to the surface of the old concrete. When the layer is still wet, pour the new concrete mixture over it.
4. How to Repair a Conduit Wall
Cracks in the wall surface also occur due to conduit or cable planting after the wall has been plastered and plastered. It is recommended that this conduit be done at least one day before the wall is plastered. Meanwhile, chapping or making cracks on the surface of the brick must be done in advance, make sure that the conduit work has been completed before starting the plastering process on both sides.
But if you want to repair the wall due to the conduit, Teman88 can use a mixture of Super Cement and cement. The trick, mix Super Cement and water with a volume ratio of 1:5, then add cement and sand according to the desired thickness. Enter the mixture into the crevices of the wall and smooth the surface. After drying, you can proceed with the painting process.
5. How to Repair Cracked Walls Due to Broken Pipelines
Installation of water or electrical pipes that are made only through plaster or only placed on brick can then directly cause cracks in the wall, this type of crack usually causes straight cracks along the pipe line. To fix this, re-ply the tape on the pipeline to a width of about 5 cm.
Then, wrap the pipe with chicken wire and fill the gap with sand cement in a ratio of 1:5 then fill with a mixture of Super Cement and water with a volume ratio of 1:5. After that, add cement and sand according to the desired thickness. Force the mixture into the wall and smooth the surface. When it is dry, continue with the painting process.
6. How to Repair the Thousand Cracked Wall
Cracks of a thousand or cracked eggs, caused by too fast application of the plaster on the plaster that has not stopped shrinking, The plaster itself has not shrunk because it is too thick in one application or because its mud content exceeds 5%, Cracks of this type when touched by hand will feel deeper.
To fix this, fill the cracks with a mixture of Super Cement and cement. The application is the same as when repairing a wall due to conduit, namely by mixing Super Cement and water with a volume ratio of 1:20, then adding cement according to the desired thickness. Put the mixture into the gap in the wall and smooth the surface. After drying, you can proceed with the painting process. .
That’s an explanation of the types, causes, and also how to overcome cracks in the walls of the house. Overcoming various types of cracks or repairing walls is certainly easier with Super Cement products from Aquaproof. One product can be used in various functions namely additives, adhesives and primers. Hopefully the article above can be useful for all Friend88!
