SB2377 HD Concrete, Mineral & Efflorescence Remover Copper Stain Removal System [Overview]

SB 2377 is one of our newer cleaners designed for the removal of thin to moderately heavy deposits of concrete, mortar and grout without the corrosiveness of using muriatic and other acids. Based on a highly concentrated blend of surfactants and salts, SB 2377 has been used to remove ½ inch of cementitious materials from masonry and metal surfaces. SB 2377 is significantly less corrosive to metal surfaces than mineral acids, therefore enough material to remove stubborn deposits can be used without worries of damaging ferrous metal parts. Depending upon the temperature, type, hardness, age and thickness of the material to be removed, reaction times may range from 15 minutes to several hours. Current testing has not produced stains on metallic sensitive clay masonry however some color changes have been noticed of darkly colored concrete blocks. SB 2377 is suitable for use on masonry as well as metallic surfaces found on concrete trucks, mortar mixers, grout pumps and similar equipment. SB 2377 will etch cementitious materials and is not suitable for polished masonry surfaces.

Preparation

Provide protection for foliage, pedestrian and vehicle traffic. Test all non-masonry surfaces for possible adverse reactions. Protect all surfaces and situations where damage may result from spillage or material drift. Conduct testing to determine the proper dilution requirement, application method and dwell time for each project.

Dilution and Coverage

Dilution: 0 to 25 parts water to 1 part product (see below) — test application recommended

Coverage: Dependent upon substrate and other conditions

Application


Masonry: To remove excess mortar and concrete splash, brush or spray properly diluted SB 2377 on the material to be re- moved after pre-wetting the surface with water. Heavy deposits can be spot treated without pre-wetting to encourage deeper penetration. Dwell times of up to one hour may be required depending upon conditions and method of removal. On softer masonry, extended dwell times will produce better results than using more aggressive rinsing methods. A thorough rinsing is required for all applications. Dilution ratios may be from 1 to 10 parts water to 1 part chemical.

Metallic Surfaces: For most grout and cement removals from equipment, SB 2377 can be diluted from 1 to 25 parts water to 1 part chemical. For very heavy deposits, you may use undiluted. Do not pre-wet the surface. Apply SB 2377 with acid brushes or low-pressure spray to the areas with con- tamination. For best results: after application, the surface should be periodically misted with water to ensure that the cleaner continues to penetrate thicker deposits. Dwell times up to 24 hours may be required. In cold weather, move the equipment into a heated area during the dwell time. In certain cases, reapplication and an extended dwell time may be required. Rinsing may be done with hoses and stiff brushes or high pressure rinsing equipment. For some exceptionally heavy deposits, scrapping may be required.
