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 Cover Exterior Brick With Stucco
So you've made the decision to have stucco applied to your home. Or, maybe you just need a repair. Either way, you'll need to look up stucco contractors in your area so that the project can be completed. You may be tempted to just open up a phone book and call the first contractor with a big ad, but that is not the way to go. Just about anyone can take out an ad, and having a larger one only means that they spent a little more money on advertising. Like any other skilled trade, learning how to apply stucco is not only an art but a science as well. Having the proper insurance, bonding, employees, portfolio of satisfied clients and ethical business practices should be the criteria you base hiring a contractor on. Doing an initial background check on a potential contractor now will save you copious amounts of work later.
First, you need to establish exactly what your project will entail. Then you need to contact a few contractors and ask them for a cost quote. It's a good idea to let them know right away that you are going to be speaking to several contractors to see what their bids are. This can save you time when trying to negotiate a good price. Throw in some terminology about your specific project if you can. You will appear to be more knowledgeable than the average customer, so you will be less likely to be taken advantage of. Once you have gotten a few quotes, look for the median price. A good contractor will price fairly. Too low of a price may indicate an inexperienced contractor, while a high price may be a predatory contractor. Find the three or four contractors that are close to the median price and contact them for more information.
Qualified stucco contractors will have up to date insurance and licensing. This information will either be on hand, or in their office. Asking to view or make a copy of their paperwork is neither rude nor uncommon. If a contractor acts insulted or repeatedly gives excuses as to why the paperwork cannot be produced, you probably shouldn't do business with them. Whether these are stalling tactics or they are just really unorganized, they are indicators of an unprofessional business person.
Using the information from the price quote and insurance and licensing paperwork should help to really narrow down the selection. The rest of the process should be based upon the estimated time to complete the project, number of employees used and portfolio of work. Looking at the jobs these stucco contractors have completed will give you a good idea of the quality of their work. By knowing how many employees work on a project and how long it will take to be completed, you can get an idea of how efficient a contractor is. Too many employees over a long period of time indicates a lackadaisical attitude combined with a low skill level. All contractors are motivated by completing a job quickly and efficiently so that they can more on to the next project.
Using all of the criteria together should help you to locate one of many qualified stucco contractors available. Although it probably took you a week or two to pick one out, you should be very happy with your ultimate selection. After you have reviewed the contract and made your first installment payment, they will be able to get to work. Very soon, you will have your stucco project completed.
