The History and Benefits of Stucco
There are three common types of stucco finishes you might choose from when applying the exterior wall to your home. These finishes include wet dashes, dry dashes, and float finishes.
The wet dashes include many different variations of stucco finishes you might choose to apply to your home. These finishes include the rough cast, pebble dash, spatter dash, broom dash, and even the sand dash. The pebble dash or the rough cast is simple to obtain by throwing the mixture on to the wall by using a paddle. The mixture will include grout and pebbles. You will throw the mixture against the fresh coat of mortar.
The spatter dash can be obtained in a similar fashion but instead using a thinner mixture of cement and coarse sand. Some people choose to use stone screenings instead of sand. This mixture is dashed against the mortar. The sand spray and the broom dash mixtures are used by actually applying the mixture to the mortar by using a long fiber brush or a whisk broom. You do not throw the mixture but apply it. The reason these finishes are called wet finishes is because you apply the finish to the mortar while it is still fresh.
The dry dash stucco finish is another common finish people prefer on their house. When obtaining the dry dash look, you will throw clean pebbles, pieces of shell, or even stone chips against the mortar right before it is hardened. It is important to try to uniformly distribute the mixture across the wall so the outcome looks nice. In most cases, you will have to push the pieces of rock into place by using drywall finishing tools like a float. However, you should not rub the surface once the pieces are embedded into the mortar. The dry dash is a more difficult finish to apply because it takes more time and you have to be more careful to evenly distribute the rocks and pebbles.
Float stucco finishes are another popular option to use on the exterior wall of a home. This type of finish is accomplished by applying the coating once the mortar has begun to harden. This type of finish requires a thin finish coat and needs to be straightened before you begin floating. Once the stucco has begun to stiffen, water needs to be dashed on the surface with a brush. Float finishes are performed by professional workmen with experience and skill. Not many homeowners attempt to do this type of finish on their home.
There are three different types of stucco finishes you might choose from if you are looking for a new siding for the exterior of your home. These types of finishes include wet dashes, dry dashes, and float finishes. Wet and dry dashes are the most common if you are thinking of performing this project on your own. If you would like a float finish on the outside of your home and you have never done this before then you might consider hiring a professional to assist you.
How to Repair Stucco Siding on Your Home
Stucco has been use to protect and decorate exterior and interior walls and ceilings for many centuries. Stucco is available in dozens of textures, thousands of colors and is currently the cladding of choice for most new construction and remodel or restoration projects.
The two main categories of exterior stucco that encompass dozens of different systems are Hard Coat Stucco and EIFS (Exterior Insulation and Finish System). Hard Coat Stucco is the preferred system for residential or multifamily construction, and is being used increasingly for commercial projects since it is more economical. EIFS is more commonly used for commercial building projects, but is often also used for high-end custom homes.
Hard Coat Stucco is typically applied in 2-3 coats with a cementitious base coat. Two commonly used hard coat stucco systems are called One Coat Stucco and Three Coat Stucco. Traditional Three Coat Stucco consists of two coats of a cement base and one finish coat. One Coat Stucco is actually a two-coat process but instead of two base coats it consists of one cementitious base coat with one finish coat. In the last few decades One Coat Stucco has become much more popular simply because of the cost. The materials used and application process are virtually the same for both systems, other than the exception of One Coat Stucco taking fewer steps and less time. The design ability and performance between the two systems are also the same, although Three Coat Stucco is typically stronger and will crack less in most circumstances.
The finish coat application of both hard coat systems is the same. There are numerous finish options but they can be consolidated into a few categories which are: Integrally Colored Stucco, Painted Stucco, and Acrylic Finishes. Colored cement finishes or "colored stucco" was the popular choice over Three Coat Stucco for most of the 20th century. It is simply a mixture of cement, lime, sand and pigment. It is inexpensive and easy to apply, however, if the base coat cracks the finish is almost guaranteed to crack. Colored Stucco will stain easily, is hard to repair, and allows water to pass freely through it (which can be good or bad depending on what part of the country the system is applied within). It is usually applied by hand and can achieve virtually any finish imaginable.
Painted Stucco has been around almost as long, and is the majority of the finishes being used today. Painted Stucco is the same mixture of materials less the color, so it is applied the same and will achieve all the textures that integrally colored stucco will. The final step with Painted Stucco is the paint application. The paint, or as some like to call "coating", will look more vibrant and is easier to patch. Color options are vast and it is important that a good quality stucco paint is used. The most desired stucco finish today is Acrylic Stucco or Acrylic Finish. Some will call this system Synthetic Stucco, which is somewhat correct since it is a synthetic finish, however it is not a synthetic system.
Acrylic Finish is available in as many colors as a paint and has the same chemical make up as paint, but is a much thicker application. This does raise the cost of the overall system, but offers many benefits that the other two finishes do not. Acrylic Stucco will bridge most all hairline cracks and does not allow water to travel freely into the system, which is a huge benefit in freeze/thaw zones. Acrylic Stucco will keep it's look and typically will not require any maintenance for many years, whereas painted stucco must be repainted and repaired within a few years. Colored Stucco stains easily, will show every crack and is very difficult to repair.
EIFS is a full synthetic system or what most will call Synthetic Stucco. EIFS systems weigh much less than traditional stucco and are much more flexible. Although most EIFS adhesives and base coats are cement based, they are heavily polymer modified so they are considered synthetic. These type of systems have been used successfully for many decades but are much newer in the stucco world. Most all EIFS systems use EPS (Expanded Polystyrene) insulation board which is usually adhesively attached to the substrate and sometimes mechanically attached. The EPS adds insulation to the wall assembly, absorbs movement better than any other stucco cladding used today, and adds many design options.
The original or traditional EIFS systems all used a cement-based adhesive and/or mechanical fasteners for the EPS, fiberglass netting for reinforcement and to gauge base coat thickness, cement base coat, and an acrylic finish. These systems are known as Barrier EIFS. Since these systems are so watertight, they've had some problems such as not allowing water to escape after it had travelled into the system because of improper application and flashing. The industry quickly designed Drainage EIFS or Water Managed EIFS which some manufacturers had and promoted before these issues arrived. Drainage EIFS systems have been very popular in recent years and include added or altered components such as notched or channeled EPS, plastic trim, trowel or roller-applied waterproof coatings. These systems seem to have remedied the water drainage problem of years past. The finish coat options for EIFS are not as vast as they are for Hard Coat Stucco. Since EIFS is a "soft system" or synthetic system, cement finishes will not work unless they are acrylic or polymer modified.
Most EIFS manufacturers have their recommended systems and will not warranty their products if deviated from the original specifications. Almost every final coat for EIFS consists of an acrylic emulsion and marble or silica sand finish that is hand-troweled over the base coat. Acrylic finish is integrally colored and very flexible. There are a few standard textures that acrylic finishes provide, including Smooth Finish, Sand Finish, and Rilled or Swirl Finish. These finishes, which are expensive, are usually applied in one coat at a thickness of 5/32" or less. Many different textures are possible by multilayering an acrylic finish.
