Preparation
Provide protection for foliage and pedestrian traffic. Test all non-masonry surfaces for possible negative reaction. Shut off all ventilation intakes, close all other entrances to the structure and provide protection to ensure that no cleaner enters the structure during application and rinsing of the surface. Protect all surrounding areas from possible damage, which might occur from spillage or spray during usage.
All projects should start with a test application to determine the suitability of the cleaner, acceptable application methods and dilution ratio. Test areas of at least ten square feet are recommended and should involve the worst area of soiling. When possible, the test area should be left to age for 10 or more days to check for possible adverse reactions.
Dilution and Coverage
Dilution: 4 to 12 parts water to 1 part product — test application recommended.
Coverage: Dependent upon substrate and other conditions.
Application
Soak the surface to be cleaned with water prior to the applica- tion of the properly diluted cleaner. Soaking the surface prior to application of the product is designed to reduce the pene- tration of the cleaner where it is not wanted and to keep it on the surface where it is needed. Start with the weakest dilution and test until an acceptable dilution is determined for the project. Apply the diluted cleaner with either acid brushes or low pressure spray. Spray application should never be done at pressures greater than 40 psi. Leave the cleaner on the surface for 2 to 5 minutes depending upon the dilution ratio and temperature, scrub with a stiff masonry brush, remove heavy smears with a wood paddle and remove the cleaner and contaminants with either a hose or pressure washer. When using a pressure washer, pressures of 600 to 2,500 psi and minimum flow rates of 4 gallons per minute have been used successfully by experienced contractors. In many cases, the use of a properly equipped pressure washer can reduce or eliminate the need for hand scrubbing and rubbing of the surface. Care must be exercised to avoid driving the cleaner into the surface creating a condition where complete removal is not possible. Avoid using wands equipped with “laser” or other tips that might cause damage to the masonry surface. In all cases, a thorough rinsing is required.
SB 2040 Custom Masonry Cleaner is for use by professional contractors only. Type “S” mortars should be cleaned every 7 to 10 days to achieve the best results. High strength mortars and mortar that is left on the surface for more than 60 days may be difficult to remove or may not be removed at all. SB 2040 is safe for use on most metallic sensitive clay masonry and colored concrete masonry units. Glazed or polished surfaces are not acceptable for cleaning. Test prior to use.
