4- Whenever you make a change to your building with renovations you must always have the work inspected afterwards to ensure that any critical waterproofing tasks are done properly and sufficiently.

5- To keep your stucco looking nice and prevent it staining, you need to clean it from time to time. Using a pressure washer is fine, but you do need to calibrate the pressure washer to the stucco recommended pressure level to prevent damaging it.

Present Day Issues With Stucco

Without a doubt, stucco is a very good cladding system. One cannot dispute that and besides it wouldnt be used if it was not any good. Stucco systems are very efficient, well designed and suitable for the majority of homes. One downside to the stucco system is that it does rely upon the installation details which are completely concealed once the application of the system has been done. Hence the most important part of the system is the flashing and moisture barrier. If the installation job is not done well or properly then the homeowner will have severe problems from water intrusion damage. It is not possible to know if the installation has been done properly until it is too late. This is because many issues are concealed behind the stucco and not discovered until a professional test has taken place. Problems behind stucco usually require large wall surfaces of stucco to be removed and replaced. This can be costly and very time consuming.

Is moisture building up in the walls?

To know what is happening behind stucco a full professional moisture inspection is required. There are many ways and methods of doing this with an array of tools. You can test areas with a moisture meter but the much preferred method is to use an intrusive probe connected with a moisture meter to test the materials behind the stucco.

A scanner or infrared camera can also be used in the quest for moisture content levels, but they cannot be used on their own. This is because any wet areas located must be probed to check for rot amd mold and of the course, the actual moisture level content. With an infrared camera as well, it will not be able to detect damaged areas in the same way as probing does. Probing will allow you to ascertain the firmness of an area. Probing is by far the best method for testing stucco for moisture content issues.

A pin moisture meter is our preferred method. You can insert the pins into the stucco and gain a reading. Once the moisture meter probes have been removed, the remaining holes can be filled in with a caulk.


Repairing Stucco


The management of moisture is the trick to keeping your stucco in tip top condition. Damage can take place in older buildings or in badly installed stucco. Water damage can result in rust and rot. Stucco is breathable and will allow moisture vapour to pass through it. This means it can dry out. Repairing stucco can be done and is a pretty much straightforward process that will leave the surfaces back in good condition.

You can paint your stucco in any colour you desire with portland cement based paints. The paint needs to be scrubbed in to the surface of the stucco and fully cured. You can use other types of paint but they will not last as long as a cement based paint.

Cleaning stucco can be done easily providing there is no biological growth, contamination or staining with it. Most dirt can be easily removed. Water temperatures, strength of scrubbing and chemical detergents can all be changed for different types of dirt.

Stucco is the name given to a type of plaster material that is applied to the outside of buildings and wooden structures. It is made up from aggregate materials, a binder and water. Stucco is applied to masonrt or wood when wet and after it has dried, it forms a very solid and dense protective coat for you building whilst looking attractive as well. Stucco proves to be a relatively low maintenance exterior finish for your home.

Stucco proves itself to be a good cladding system providing that any construction defects are repaired before application and the system is well maintained. As of today there is no such thing as a maintenance free cladding system for you home. Leaks can occur in all types of cladding systems but it must be noted that any leaks with the stucco system must be maintained immediately because of the destructive nature of water intrusion. With your stucco cladding system this is critical. Your first line of defence against water intrusion are the sealant joints. In many cases theses sealant joints are your only defence against water intrusion. Any water intrusion can result in your synthetic stucco system breaking down and the appearance of your home downgrading rapidly. But with proper care and maintenance of your stucco system you will get many years of good function from it and your home looking very nice with it.


To protect your home stucco system there are several steps to be taken;

1- Once or twice a year you should thoroughly check all sealants around your windows and doors. Look for any penetrations that have happened through your stucco. If you find any cracks in the stucco then they must be repaired promptly.

2- With any leaks, cracks or any discolouration with your stucco you must investigate the cause and rectify it. If you notice mold then you definitely have yourself a moisture issue that must be resolved.

3- When you mount a satellite dish or a new security system you will make a penetration through the stucco. You must always seal theses penetrations with a quality approved sealant.
