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.
How to Patch Exterior Stucco Cracks
If your home improvement project involved stucco, you will want to be sure you find the right contractor for the job. It is always important to hire good contractors, but it is especially important when they will be doing work such as stucco installation, which is not as common as other contracting duties. You need to work with a people who know how do to the job properly, so you can be sure it will get done right the first time.
Fortunately, you shouldn't have much trouble finding a good contractor, as long as you know what questions to ask during the process. Use the tips in this article to help yourself sort through the field to pick out the perfect stucco contractor for your job.
Get Multiple Bids
The biggest mistake that homeowners make when picking out any type of contractor is only getting one or two bids as part of the process. You should treat this project just like you would treat a commercial job - you need to secure multiple bids in order to select the best option for your needs. It should be noted that the lowest bid doesn't automatically win. Instead, you need to weigh all factors, including price, experience, referrals, and more before selecting the company you will hire. It should only take a day or two to contact multiple companies with a request for a bid, so you can have much of the information you need within a short period of time.
There Should be a Guarantee
When you get the bids, make sure to ask if the work will be guaranteed once it is completed. A quality contractor will stand firmly behind their work, so don't hesitate to ask this question. If the labor and material are not covered by some form of guarantee, you should quickly move on to the next bid. There are plenty of contractors out there who are willing to stand behind their work, so there is no reason to work with one who isn't.
Keep It Clean
Stucco can be messy business. Make sure there is a plan in place to protect the rest of your property from the mess that can be made when stucco is put in. You don't want to be left with a huge cleanup project after your contractor has left the job site, so ask specific questions as to how they will keep the rest of your property as clean as possible.
All contractors should have references, and it is no different for those who work in stucco. Don't just ask for references, however - be sure to call at least a couple of them to inquire as to the quality of work that they received. This is your best chance to get an unbiased review of the work that was completed, so have a list of specific questions prepared when you give a call to one of the provided references.
Everything in Writing
It doesn't matter if someone 'seems' trustworthy or not - get everything in writing before a project starts. This contract is meant to protect both parties, so make sure that the language is suitable for your needs before you sign on the dotted line. Once the work that is to be done is clearly outlined, along with the costs for the project, you can go into the job with confidence that you will reach a successful conclusion.
Hiring a stucco contractor doesn't need to be a long and drawn out process, as long as you know what you are looking for from the start. Use the points above to guide your search, and only hire a contractor once you are fully satisfied that they are the perfect selection for the work that you need completed.
