There is a stating out there that goes … “There are 2 types of stucco homes, one that is split and ones that are going to”. Cracking is inescapable when it concerns stucco, much like any type of cement based item. Expansion, wind and stress all play important roles in why cracking occurs.
Other issues that cause breaking problems in plaster can be induced by incorrect setup of lath, incorrect mixing treatments and a couple of other variables. There are particular patterns that will allow you to identify exactly what in fact triggered the wall to crack.
Lets have a look at a few of the different types of crack to get a better understanding of why they happen.
It is normal for plaster to split from motion and stress, specifically in a brand-new home. The wood dries, the vibrations from the construction equipment and other elements play a significant function in this for a brand new home.
Hairline fractures are normally around a 1/16 of an inch wide or smaller sized, if the fracture is bigger than that, than opportunities are that some other element is the culprit. Below are some examples of some hairline fractures that have taken place.
Cracks Regarding Foam Trim:
I see a great deal of cracks on the foam trim that is used on stucco homes frequently and the majority of the time it is where two pieces of trim satisfy. The cause is normally because fiberglass fit together tape was not utilized on the joint where the two pieces satisfied.
If installed like this, it will likely crack gradually due to shrinking, expansion and contractions that are induced by the elements. Let’s take a look at some examples …
This type of splitting is basically an indication that the base coat did not cure properly. This is brought on by either drying too rapidly, too muck water in the mix, or mixed incorrectly or used when it was too cold or too hot the day the stucco was used.
Patterns In The Wall:
When there are defining vertical and/or horizontal breaking happening throughout the wall, then more than most likely it is caused by the lath. Either the lath (the wire specifically) was not nailed or stapled off properly which is a more severe type of breaking.
Since the wire is essentially loose in some areas, then it will actually have a higher potential for forming even more fractures as time goes on. To correct the problem, the stucco has to be broken out and the lath has to be nailed off or changed.
Diagonal Type Breaking:
Sometimes you will see a diagonal type pattern that will signify some other kind of issue. Theses are typically in the basic classifications of seismic motions, house settling or shifting, and so on. The ones that have the tendency to establish around a door or window are the cause the framing in the door or window or due to vibrations because specific area.
Some are more major than others, generally a great general rule is the size and depth of the fracture. If it is more than 1/8 of an inch wide, then it should be a bit higher on your priority list than smaller sized ones.
