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.
Making The Proper Repair Of Walls And Ceilings Using Stucco
Stucco Ceiling Painting
Stucco repairs usually happen when something goes wrong above the drywall in the ceiling - Probably a leaking toilet or an overflowed bathtub or sink. If this problem was caught quick enough and all that happened was the drywall got a little damp and stained the stucco and didn't ruin the adhesion between the stucco and the drywall, you're safe.
So if you have a brown stain or black stain on your ceiling in the stucco all you have to do is seal the stain with some stain killer in a spray can. Probably the color of the stain killer in the can is not the same color as the rest of the ceiling.
If you have to repaint the ceiling, and the ceiling was never painted before, you will have to paint this with some oil based paint.
Things you will need, make sure the floors are properly covered. You might want to cover the walls also so that the roller spray doesn't spray onto the wall. You'll need one gallon of flat oil paint probably or two depending on the size of your ceiling and also do consider that a never painted ceiling uses up more paint. Make sure you have a gallon of paint thinner or solvent for any cleaning.
The way I recommend painting ceilings is in three-foot squares, don't try to paint in long strokes. Just keep it above your head basically and paint boxes just overhead and overlap the boxes as you make them. and the other comment that I can add to this, don't be cheap with the paint. The more you try to stretch the paint the bigger chance you will have leaving streaks or misses or blotchy marks.
