Preparation
Provide protection for foliage and pedestrian traffic. Shut off all ventilation intakes, close all other entrances to the structure, provide temporary caulking if required and provide protection so that no cleaner or cleaner fumes enter the structure during application and rinsing of the surface. Protect all surrounding spray during usage.
All projects should start with a series of test applications to determine the suitability of the cleaner for the subject surface and to determine the proper dilution ratio. Some projects might require different dilutions for different masonry that may be a part of the same facade. Test areas of approximately 10 square feet are recommended for each type of masonry surface and should be left to age for 10 or more days to determine if there are any latent reactions that might require a modification of the cleaning method 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 3 parts water to 1 part product. Test application is highly recommended to determine dilution rate and appro- priate dwell time. Optimum dwell time and dilution rate may change with weather conditions.
Coverage: Dependent upon substrate and other conditions.
Application
If the SB 2130 Limestone Neutralizer is being used as a one step cleaner, the surface should be pre-wet prior to application. When using SB 2130 as a neutralizer, the properly diluted solution must be applied to the surface immediately after removal of the Step 1 cleaner and prior to the drying of the surface. The preferred application method is by low-pressure spray. The use of brushes and rollers might contaminate the neutralizer during reloading of the applicator. SB 2130 should be used undiluted or diluted with 1 part water when used as a one-step cleaner or as the neutralizer for SB 2150. Dilutions with 2 to 3 parts water can be can be acceptable when used as a neutralizer for SB 2120 Limestone Prep or SB 2140 Masonry Restorer NA.
SB 2130 Limestone Neutralizer is for use by professional contractors only. When using SB 2130, as part of a two-step cleaning system, always refer to the Step 1 data sheet [SB 2120, SB 2140 or SB 2150] in conjunction with the SB 2130 data sheet to assure the proper usage for the system.
