Provide protection for foliage and pedestrian traffic. Test all surfaces which might be exposed to product for possible adverse reactions. Protect all surfaces and 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 method and dilution ratio if applicable. Test areas of at least 10 square feet are recommended and should involve the most severely contaminated condition. When possible, the test area should be left to age for 10 or more days to check for any latent reaction that might require a change in methods or products.
Dilution and Coverage
Dilution varies dependent on the surface, porosity of the sur- face and degree of soiling/stains, etc. Initial recommended dilution is 0 to 10 parts water to 1 part product. Test applica- tion is highly recommended to determine dilution rate and appropriate dwell time. Optimum dwell time and dilution rate may change with weather conditions.
Coverage: Dependent upon substrate and other conditions
Thoroughly pre-wet / soak the surface to be cleaned prior to the application of the properly diluted cleaner. SB 2140 may be applied by low-pressure spray, synthetic fiber brush or roller. Brush agitation may be helpful on some projects. Dwell times may vary from 5 to 30 minutes. Do not allow the cleaner to dry on the surface. After the predetermined dwell time has passed, rinse the surface with a quick low pressure rinse. This is neces- sary to remove excess cleaner and stop the reaction. Follow with a thorough high pressure rinse as appropriate. Removal of the loosened dirt and contamination can be accomplished with high pressure rinsing equipment. Care should be taken in the selection of the wand tip to avoid damage to the masonry surface. In all cases, a thorough rinsing is required.
Two Step Process: In cases where a heavy buildup of carbon, soot, atmospheric soiling and organic growth are combined on a surface, a two step process may be necessary. Step 1 is to apply the SB 2140 as directed above to break down the heavy crust that most acid cleaning products cannot effectively remove. Then rinse completely using high pressure spray. Step2: the application of SB 2140 followed by a neutralization and final cleaning with SB 2100 ProStore Restoration Cleaner, SB 2115 Heritage Restoration Cleaner, or SB 2130 Limestone Neutralizer will result in a neutralized project. See data sheets for the application of these products.
SB 2140 Masonry Restorer NA is for use by professional contractors only. Projects should not be undertaken when temperatures are below 50 degrees F. Do not allow the cleaner to dry on the surface. Misting of drying cleaner is permissible to avoid possible reapplication. Do not use on polished masonry.
