HOW TO REPAIR A CRACK
BROUGHT TO YOU
A little in all the houses there are cracks caused by settlement or structural or malpositioning of the
bricks. Often, however, uneconomical and a great waste of time to call the workmen to repair. We will
explain how to succeed to perform the repair in a simple and fast, saving of time and a considerable
amount of money.
To do this repair you will need the following materials and tools:
- HAMMER: If you do not have one does not do anything just to have a mazzotto and a chisel.
- CEMENT: do not use quick drying cement or derivatives for a good job.
- SAND: sand to not worry if you do not find a guy like that in the picture the sand from building varies
from country to country depending on the type of rocks from the ground.
- PLASTER: the plaster have to be careful, if the crack is internal or external, must be adapted to the type
of plaster for a crack outside is fine to coarse but only if the crack is internal need to put a layer of grain
coarse and one fine-grained, so it is better to be sanded and also the yield is better.
- GARZA: is available in all stores building.
- VACUUM FILLER
- With the demolition of the crack spread five or six times the original size, removing all debris until the
brick, but being careful not to break it. This operation will go well also mazzotto and chisel.
- Clean it all, and pour of 'water on the crack to attack the cement that we will later.
- Put the cement and sand in Caldarella (for each Caldarella sand pour three or four manicole of cement)
add the 'water and mix well.
- Apply cement to the crack filling until leaving about an inch below the wall. To ensure that the cement
penetrates well and fill it all you have to put a little on manicola and throw it at the crack (quiet you will
attack alone). With the still fresh concrete applied a strip of gauze at the point where there was the
crack will prevent return over time. Left to dry for a whole night.
- Prepare the plaster and spargetene small piles on the wall, then with the putty knife to spread it well
by applying a certain pressure on the wall, making this the excess plaster will come off. Keep adding
until all plaster will not be leveled.
As you can see repair a crack is a simple task that will take a considerable saving of time and money.
In the example of today we have repaired a crack about 1.5 m deep and very thick. We spent a total of $
13.40 if you had to call a worker would not have spent less than $70 considering the costs of labor and
the possible markup on materials.
Home Repair for Masonry Wall Cracks
You need: hard bristle brush, paintbrush, cup of water, cement and a putty knife.
Bricks, concrete and limestone may show occasional cracks. Remove debris with a hard bristle
brush. When you are sure that no more loose bits and pieces come out, switch to the paintbrush
to get rid of dust. Dip the paintbrush into the cup of water and moisten the inside of the crack.
Scoop up a glob of cement with the putty knife, apply it to the crack and smooth it into place.
Protect the cement from moisture, let it dry completely and then paint over the fixed crack.
Plaster Repair for Minor Cracks
You need: paintbrush, fiberglass mesh, joint compound, putty knife and sandpaper.
If you have plaster on your walls, home repair is a given. Use a dry paintbrush and clean out the
cracks. Visit your local home improvement store and buy fiberglass mesh tape. While you are
there, pick up a tub of joint compound as well. Some experts prefer the powdered version that
you mix at home with water. Try the tub first, but if the repair work is not to your liking, invest
in the more labor-intensive dry mix.
Apply fiberglass mesh over the crack. Smooth joint compound with the putty knife over the
fiberglass mesh and let the mixture dry. Repeat until the crack is filled and virtually invisible. It
is a good idea to work in thin layers rather than trying to apply a thick glob at the onset. Finally,
sand the area to let it blend in with the rest of the plaster wall.
Drywall Repair Tips
You need: joint compound, putty knife and sandpaper; fiberglass mesh is optional.
More often than not, learning how to repair a crack in the wall brings you face to face with
drywall. You will be heartened to learn that drywall repair is virtually identical to plaster repair,
except that you do not need to use the fiberglass mesh unless the wall crack involves the seam
between two sheets of drywall.
Apply joint compound to the crack in the drywall with a putty knife. If a seam is affected,
remove old drywall tape and replace it with fiberglass mesh over which you then smooth the
joint compound. Let the area dry and repeat as often as needed. Sand lightly, so as to let the fix
blend in with the rest of the wall.
Stucco Wall Crack Repair ... Beyond the Scope of Newbies?
You need: paintbrush, low modulus acrylic caulk, builder sand and plenty of patience.
As you can see, drywall repair or a crack in the wall that necessitates plaster repair is not that
hard. A stucco wall — in essence — is also a simple home repair chore, until you get to the
artistic aspect of matching your stucco patch to the existing texture.
Clean out the crack with the paintbrush. Apply paintable caulk to the crack. Let the caulk dry for
about a week and then repeat the step. Mix builder sand in with the last layer of caulk to mimic
the appearance of the stucco. This requires finesse and an artistic flair, which makes it the most
time-consuming and frustrating aspect of the project.
