Arriscraft.CARE – Keys to Proper Product Cleaning
You should understand our cleaning guidelines, even before installation begins. Please review these important tips!
Cleaning Preparation
Prior to commencing construction, it is imperative to test-clean either a mock-up panel or samples of the Arriscraft masonry units in a manner similar to how the building will be cleaned. Temperature, humidity and the method of cleaning will impact the cleaning operations and the ultimate look of the wall. Inspection of the test panel or samples should occur after a 3 – 7 day drying time. This test should be available for the architect to inspect and approve, then remain as the standard for the project.
Certain precautions must be taken during construction to minimize the potential for colour changes resulting from the cleaning process and to ensure a more consistent in-the-wall appearance. Refer to the Installation section in How to Protect Product at Every Stage. Removing mortar droppings and smears from the masonry units, as the work progresses, will minimize cleaning requirements. Cleaning the constructed walls with water and non-acidic detergent will minimize any colour changes that can occur during cleaning. Many acid-based detergents and proprietary cleaners will alter the colour of the masonry units.
After approval of the test-cleaned material, it is imperative that the same cleaning procedure be used consistently throughout the cleaning of the building. Failure to follow these procedures can result in uneven or streaked colour.
Cleaning Guidelines
Regardless of the cleaning method considered, it is essential to pre-wet the masonry surface before applying any type of cleaning solution. Pre-wetting the masonry units will minimize their absorption of the cleaning agent. It is equally important to keep the units wet during cleaning operations and, upon finishing, to thoroughly rinse any cleaning solution from the wall surface. The key to successful cleaning is a continuous source of a sufficient volume of clean water throughout the cleaning operations.
Cleaning operations should commence at the top of the wall and work their way progressively down the wall surface. This will prevent dirt or stains from being washed onto areas that have already been cleaned.
Avoid applying the cleaning solution with pressurized spray systems, as this will tend to drive the cleaning solution into the pores of the masonry. The use of medium-pressure (300-700 psi) rinsing water is appropriate. High-pressure (>700 psi) methods should be avoided for cleaning manufactured masonry products as it may result in a texture change. High-pressure methods may also damage the mortar joints.
Cleaning with Acid-based or Proprietary Masonry Cleaners
The colour of the Arriscraft Masonry Units may change with the application of either acid-based solutions or most proprietary masonry detergents. Refer to the test-cleaned material to determine the effect of the selected cleaning method on the colour of the masonry.
If required, properly mask or otherwise protect metal, glass, wood and other surfaces from damage by exposure to the cleaning solution. Schedule cleaning operations no sooner than 7 days but not later than 28 days after the masonry has been completed. Remove larger mortar droppings by hand with wooden paddles or a non-metallic scraper.
Thoroughly pre-soak the area of wall to be cleaned. Dilute the cleaning agent with clean water in controlled proportions according to that approved on the site panel. Apply the solution to the pre-soaked area of wall with a soft bristled washing brush or low pressure (max. 40-50 psi) acid-resistant sprayer. Thoroughly rinse any cleaning solution and residue from the wall surface.
