How To Repair Cracks In A Wall Or Ceiling?


Walls or ceilings can quickly show minor damage such as cracks. This may be the result of structure of the house, but can also be caused by other causes such as small earthquakes.

As long as the cracks are not completely through the wall, that is, as long as the cracks are on the surface, cracks often can be repaired or restored.

The finish of the wall or ceiling after recovering from a tear is doable, although the end result depends on the accuracy and quality of the materials being handled.

Repairing Or Restoring Cracks In The Wall Or Ceiling

The cracks formed in a ceiling or a wall can be repaired by setting materials properly. Such cracks are often caused by materials such as concrete or grout in the walls which still contain moisture from the construction of the house.

This moisture is not quick to dry enough, it takes several years, for the materials to remain slightly shrink until the moisture is gone. During this time the house is often already finished, so the finish can also rupture.

Also, plates which are used for ceilings can contain cracks, this can be done by the operation of the ceiling panels.

The influence of the (slight) changes in temperature in the house can also be one of the main causes. If the material has no place where it can expand or contract, it finds the weakest spot to cracks.

This is often the place where the plates touch each other, and where the gap is densely filled and finished.

A Rift Between Working Materials

For the repair of cracks in the housing, it is important to know if the crack is at a place that is able to work on.

If the crack is located at an interface between different materials or on joints between two of the same materials, the chances are that this place should continue to be operated with the materials used.

If the tear extending across a plate of the same material or across a wall, the chances are that these cracks are generated during the initial set up of the house. Such cracks are easier to repair than cracks that are located in areas that remain in working order.

Deepen the tear and remove loose material when a crack is on a wall or ceiling. For the repair of a crack, it is important to deepen the crack.

Use a scraper or screwdriver and remove any loose material from the crack. Work here in particular with a piece of the side, so that the crack is wider.

If the large loose material is removed, then wipe the dust off the elaborate tear away. Then use a flexible filler to fill the joint.

Flexible filler or filler flexible or putty is available for various materials, so opt for good work material so that the correct filler can be used. Lubricate the tear packed and smooth the excess material by means of a putty knife.

By pulling back in the length of the crack with the filler in the wall, the filler can be precisely flush with the wall to be drawn. Let the filler dry up below in the wall and then use again an additional layer of filler.

With some types of flexible filler, after they have become dry even deeper into the joint which comes to lie, the crack is not exactly the same with the rest of the wall. In order to pull this, a second layer of filler with the same materials can be used.

Look carefully at the finishing of the filled crack and the packing of the filler to see how long it has to dry before it can be finished. The finish can then take place by a coat of paint.

Choose this preferably elastic and crack bridging latex paint. Other paints may not be able to track the work of the ceiling or wall which creates a crack again.

Even with plaster or stucco, it can be worked through in the same way as described for other walls and ceilings. Use or fillers which are suitable for this purpose, for example, plaster is a special filler that is available and can be better to follow the structure.
