2101 Heavy Duty Restoration Cleaner is a very highly concentrated blend of acids and other beneficial additives for use in the removal of heavy exterior atmospheric soiling and most stains found on brick, sandstone, fired clay products and unpolished slate and granite. 2101H.D. should not be used on marble, limestone, Buff colored masonry or concrete products. When diluted with water, this product makes a highly effective, low cost cleaner for the restoration of most exterior masonry surfaces. When properly tested and applied, 2101 H.D. Restoration Cleaner is a vast improvement over abrasive cleaning.

PreparatioN

Provide protection for window glass, aluminum frames, painted surfaces, 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, provide temporary caulking if needed, and provide protection to ensure that no cleaner or cleaner fumes enter 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 series of test applications to determine the suitability of the cleaner for the subject surface or surfaces and to determine the proper dilution ratios. Some projects may 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 involve the most difficult cleaning situations. When possible, these test areas 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 methods or ShoreBest products.

Application

Pre-wet the surface prior to the application of the properly diluted cleaner. Apply the diluted cleaner with either acid brushes or low pressure spray. Spray application should not be done at pressures greater than 40 p.s.i. Leave the cleaner on the surface for the appropriate time as determined during testing. Do not let the cleaner dry on the surface. Scrubbing with stiff masonry brushes may be beneficial in some cases. Remove the cleaner with pressure rinsing equipment that provides a minimum flow rate of 3.5 g.p.m. and offers a series of fan tips not narrower than 15 degrees in width and up to 45 degrees in width. Avoid the use of "laser" tips and other pressure acceleration tips. Always be aware of cleaner drift during application and rinsing to avoid possible damage.

Limitations

2101 H.D. Restoration Cleaner is for use by professional contractors only. Some soiling conditions may require a two step cleaning method with the first application being 2140 Masonry Restorer NA followed by 2101 H.D. The need for this method should be determined during the testing phase of the project. Refer to the 2140 Masonry Restorer NA, or 2150 H.D. Carbon Crust Remover Data Sheets for more information on this procedure. The use of dilutions ratios of less than 5 parts water to one part 2101 H.D. should be avoided and must require the acceptance by the architect or project manager prior to any cleaning undertaken at this concentration.
