Different Cleaning Methods For Masonry Walls
Cleaning masonry tools is crucial for preserving the beauty of a concrete masonry building. However, different masonry walls require different cleaning methods. Aggressive cleaning methods can alter the appearance of nonarchitectural concrete masonry units (CMUs), while some units are more forgiving of soiling and efflorescence. The choice of cleaning method should be based on the specific type of masonry being cleaned.
For ground faced units, it is important to keep them clean and free from mortar smears and droppings during construction. On the other hand, split faced, split fluted, and tumbled units are more forgiving of soiling and efflorescence. Glazed CMUs, which have a smooth surface resistant to staining, should have mortar and grout smears cleaned off before they harden.
It is advisable to choose a mortar color that matches the CMU color, as this makes cleaning mortar smears easier. Additionally, lower-strength mortars are easier to clean off the wall than stronger mortars. By understanding the specific characteristics of different masonry walls and selecting the appropriate cleaning method, one can ensure effective and safe cleaning without damaging the masonry surface.
Cleaning Tips For Specific Masonry Units
When it comes to cleaning masonry tools and materials, different units require different care. Here are some important considerations:
- Ground faced units should be kept clean and free from mortar smears and droppings during construction.
- Mortar smears on glazed CMUs should be promptly cleaned off before they harden. The selection of a mortar color that matches the CMU color can aid in easier cleaning of mortar smears.
- Split faced, split fluted, and tumbled units are more forgiving of soiling and efflorescence.
It is important to protect non-masonry materials from contact with stain removers or physical cleaning methods. To prevent staining, cover adjacent construction procedures when cleaning masonry tools. Plastic sheets can be used to protect the wall from droppings during the cleaning process.
Additionally, abrasive cleaning should not be used on ground faced units as it can damage the surface.
Choosing The Right Mortar For Easier Cleaning
Choosing the right mortar is crucial for easier cleaning of masonry walls.
- Mortar color should be selected to match the CMU color to facilitate the cleaning process.
- Lower-strength mortars are generally easier to clean off the wall than stronger mortars.
By considering these factors during construction, the cleaning process can be simplified and made more efficient.
Proper Construction Practices To Minimize Cleaning Needs
Implementing proper construction practices can minimize the need for extensive cleaning. Efflorescence control during construction is of utmost importance. This involves managing the moisture content and ensuring proper moisture control to prevent the formation of efflorescence, which can cause unsightly stains on masonry surfaces. Additionally, protecting masonry from adjacent construction procedures that may stain it is also essential.
To minimize the need for cleaning, it is recommended to test cleaning methods on a sample panel or inconspicuous location first. This allows for the identification of the most effective and safe cleaning techniques. Furthermore, maintaining uniformity in the cleaning process is important to ensure a consistent appearance throughout the masonry structure.
Water Cleaning Methods For Masonry
Water cleaning methods are commonly used for cleaning masonry and can include scrubbing, soaking, steam cleaning, and pressure washing. When using water, it is important to limit its usage to the minimum amount necessary to prevent efflorescence.
- Unpainted walls can be cleaned with water and a small amount of detergent, while clay or dirt should be removed with a dry brush to prevent staining.
In the case of greasy surfaces or cold weather, heated water can be used for cleaning. However, it is important to avoid using hot water with acid cleaners as it can cause chemical reactions that may damage the masonry surface.
When pressure washing, the minimum pressure should be used to prevent driving water into the wall. A wide flange tip should be used, and the tip should be kept at least 12 inches from the masonry surface to prevent any damage.
Steam cleaning, although slower than pressure washing, is a less aggressive method that can be effective in removing dirt and stains from masonry surfaces.
It is important to exercise caution when using chemical cleaning agents in combination with water washing techniques. Diluted acids should be used sparingly and with caution to avoid damaging the surface.
