Often we come across the interior walls cubicle toilet phenolic of our homes suffered cracked irregular. In fact, during the construction process, we’ve been monitoring is attached to one of the artisan’s work. But this is still often the case. What exactly is the cause?
1. CRACK HAIR
As many of us have encountered usually irregular pattern of cracks and the cracks are small.
Forming elements are not homogeneous plastering materials, such as sand is not clean and still contain the soil.
Pengacian is not time to do the plastering. Pengacian can only be done at least 2 weeks after plastering.
Hair cracks enlarged by using a putty knife.
Then close the cracks that have been enlarged by plamur wall.
After plamur wall dries, abrasive surface. Next do the painting.
2. CRACKED WALL STRUCTURE
The pattern of cracks on the wall forming a diagonal field and usually large. There is also a pattern of vertical rift with the slit in the bottom section are large.
At the crack pattern diagonal, wall experiencing shear force is usually caused by an earthquake or a foundation point decline.
While the pattern of vertical cracks, usually sloop spot beam bertumpunya suffered a broken wall.
The floor was dug to see the extent of damage on the beam sloop.
Make a reinforcement beam on a sloop that experienced the fault.
After the repair the sloop, patching the cracks that exist by increasing the bonding agent.
Plamur and subsequently re-paint the walls that have been patched.
3. PREVENTING CRACK IN THE WALL
To prevent cracking walls, use a stucco building blocks of good quality, ie good quality cement and sand mixed with soil or sand can also use white.
As an alternative, for plastering a good quality can use this type of instant plaster that has a more homogenous mix / equitable and high adhesion. Although the price is relatively more expensive, but according to the quality obtained.
Giving sufficient time between the stucco and pengacian (approximately 2 weeks / 20 days) can prevent cracks in the walls. Be careful when working in the rainy season, because the required drying time is longer.
The stirring process between the cement, sand and water should be homogeneous / uniform to prevent cracking. For wet areas, a mixture of cement: sand is 1: 2 or 1: 3. For areas not wet / normal conditions, use a mixture of 1: 6 or 1: 8.
Temperature changes constantly can lead to fractures. Because the exterior walls need to be protected by the eaves / overstek spotlight tampias sun or rain.
Cracks are also common in around the door frame or wooden windows, due to the expansion and contraction of the wood. Because of the use of wood is completely dry (wood oven), to minimize the risk of expansion-shrinkage.
To pit doors or windows are large, use a brick structure that serves rolaag system sustains the burden of bricks on it. So wooden window frames or doors do not curl when receiving a load bricks on it.
