Why Use Stucco For My Home?

Stucco has been used in architectural structures since the Greek and Roman era and during the Renaissance. It spread throughout Europe and gradually became popular in America. Stucco is a finishing plaster composed of sand, lime, water and other ingredients. It is a strong, attractive and damage resistant covering for walls and ceilings. It is an excellent building material for hot areas as it helps to regulate the temperature. It is non-combustible and its surface burning properties include no flame spread and no smoke development.

Currently, there are two distinct types of Stuccoes –

Traditional/Hard Coat Stucco – This is basically cement mixed Stucco. The traditional stucco is durable and able to withstand harsh environments. It is porous and can breathe, so, dries quickly and resists water damage.

Conventionally, lime was used with sand and water. As lime is slightly soluble, the mixture has a self-healing tendency. At present, stuccoes are usually made up of Portland Cement, sand and water resulting in a hard and brittle variety.

To install hard coat stucco, first the substrate is installed followed by a metal lath and then a coat of stucco is applied with a trowel. It is allowed to set and then another coating is applied. Normally, the process involves a scratch coat, a brown coat and a finish coat (may be colored).

Stucco can also be applied on a paper and wire. The coats should be thicker. The first coat (scratch coat) covers the wire. It needs to be scratched as soon as it sets. The second coat (brown coat) gets bonded to this coat and as usual the finish coat is the outermost layer.

Synthetic Stucco – Since 1950s, a number of houses were built using a variety of synthetic materials resembling stucco. Fibers and synthetic acrylics were added to the cement stucco mixture to add strength and flexibility. In general though, the synthetic stuccoes are less heavy and hence, more susceptible to a hard blow. They are a one-coat stucco system unlike the three-coat traditional ones.

The most common one is EIFS or Exterior Insulation & Finish Systems. They are glued or mechanically attached to the substrate and usually composed of three layers. The innermost layer, mostly made up of polystyrene like material, is a foam insulation board. The second layer is a base coating attached to a fiberglass mesh and the final layer is a finish colored coat. It became popular because of its easy installation, low cost and better insulation properties. The only disadvantage is moisture absorption which causes water damage to the building.

A variety of stucco colors/paints are available. Colorants are inorganic pigments which can adapt with the high pH value of cement. They can be either natural like, Ochers and natural earths or artificial, such as man made Iron Oxides. Natural colorants remain unaffected to UV rays and are more pleasant to our eyes. But, the range of shades and the tinting strength is less when compared to manufactured colors. Man made colors, on the other hand, offer a wider range of shades such as dark blues and greens as well as various earthy tones like, yellow, brown and reds. They also possess excellent UV stability due to the presence of inorganic pigments.

Stucco Cracks When To Worry

What Is Stucco And Why Is It On A Home's Exterior?

If you are building a new house, then you will have to face a few annoying tasks in the process. One such task is, getting your house insulated. Insulation is one of the important jobs when building a new house, as it will save you from cold and moisture during the winter season. But, choosing the right type of insulation could be a lot frustrating, therefore I would suggest you that you should opt for the stucco insulation.

This is perhaps the most convenient and affordable way of getting your house insulated from all sorts of extreme weather. I would like to mention a few important facts related to stucco installation, which will help you get a better idea about this particular technique of insulation. Stucco insulation will create a permanent barrier in your house against all sorts of weather conditions.

I have seen many people using a metal backing before applying the stucco, which is a good practice. You can do the same with the help of a contractor, as they can finish the task quickly and easily. You will find a number of options when applying for this type of thing. This will prove to be a good barrier because it is applied in three different layers. A layer of spray is also applied to fill in all the holes that exist at the time of placing those layers.

You can't get such kind of insulation in a Styrofoam or fiberglass, like the one you get from the stucco insulation. Stucco is better because it has the ability to capture the empty spaces of the surfaces on which it is applied to. This is an important feature and must not be overlooked. You can use stucco in many different places where other insulation can't be used. There are a number of places where insulation needs to be done in a proper way or else, your home will not stay warm and dry.

I would like to tell you that there are so many options available for you these days regarding the best insulation. There is nothing much to worry about the mold that grows on the surface of the walls because stucco doesn't let that mold grow. Mold can create difficulties for people to breathe in the house and it is one of the most difficult things to get rid of as well. I have seen many houses in which the mold has done a lot of damage without even being coming into the notice of the members of the house. But, stucco will not let the mold grow, thus saving your house for a long period of time.

You can apply the stucco insulation on the exterior of the walls or sidings. There is a particular reason behind it, which is, it will work much better as a barrier than the insulating materials, which I have mentioned above. You must pay an extra attention towards having a good insulation for the building. The stucco installation will keep all the cold as well as the moisture out of the building.

The stucco insulation will acts as a water resistant, which is will not just help in keeping the flood out, but also the moisture that arises with the changes in the temperature, storms and many other things. It doesn't matter, what kind of reason is creating moisture, this insulation will eliminate all of it. Stucco is not something, which will wear off on its own, if you want to get rid of it, then you have to remove it. But, I don't see any reason to get rid of the stucco, as it provides so many benefits to you.
