Preparation
Provide protection for foliage, auto and pedestrian traffic, all painted and anodized surfaces. Test all other non-masonry surfaces for possible adverse reactions. Protect all surfaces and surrounding areas from possible damage which might occur from spillage or spray during usage. Undiluted SB 2150 is very corrosive to paint and aluminum.
All projects should start with a test application to determine the suitability of the cleaner, acceptable application method, dwell time and in some cases dilution ratio. When cleaning heavily soiled surfaces, the cleaner can be used undiluted but is often diluted with 1 to 3 parts water. Test areas of at least 10 square feet are recommended and should involve the most severely contaminated area. When possible, the test area should be left to age for 10 or more days to check for possible latent adverse reactions that might require a change in cleaner or cleaning system. On some stones with appreciable iron content the surface layer may change to a redder color. This can be reversed in most cases with the application of the SB 2301 Heavy-Duty Rust Stain Remover.
Dilution and Coverage
Dilution: 1 to 3 parts water to 1 part product-test application recommended.
Coverage: Dependent upon substrate and other conditions
Application
SB 2150 may be applied by low-pressure spray or synthetic brush. Do not use aluminum tank sprayers. Dwell times may vary from 15 to 60 minutes. Do not allow the cleaner to dry on the surface. If drying occurs, a light misting of the cleaner with water or more product will return the cleaner to active status. When the appropriate dwell time has elapsed, use high volume, low pressure water to rinse most of the residual cleaner straight down the building. Then remove the soiling with high-pressure water rinsing equipment. This two rinse process significantly reduces the possibility of splashing excess cleaner onto objects not intended to be cleaned. When using the two-step method of cleaning where a second acidic cleaner or neutralizer is used, rinse the SB 2150 / SB 2151 as above before applying the second cleaning product. The second product, properly diluted neutralizer/cleaner, should be applied to the rinsed area before the surface dries. If the surface has dried, a thorough wetting of the area will be required prior to applying the second step. Do not leave a SB 2150 / SB 2151 cleaned surface to sit over night without neutralizing in any case.
SB 2150 / SB 2151 is for use by professional contractors only. Do not use SB 2150 / SB 2151 on black marble or allow contact with any polished masonry surface. Do not allow the cleaner to dry on any surface.
