General Preparation
Protect adjacent and surrounding building hardware surfaces not intended to be cleaned from exposure to the cleaning solution. Avoid direct contact with foliage. Cover landscaping using plastic or wet the foliage with water before and after the cleaning process.

Surface and Air Temperatures
Excessively high or low temperatures will produce poor results and possible harm. Best cleaning results are obtained when air and surface temperatures are 40° Fahrenheit or above. Do not clean when temperatures are below freezing or will be overnight. If freezing conditions exist, allow adequate time for surface to thaw. If air temperatures exceed 90° Fahrenheit, flash cool the surface with water before applying product. Do not allow products to dry on the surface. Always rinse thoroughly while still wet.

Always test prior to beginning full-scale cleaning operations. Testing should confirm cleaning effectiveness on each type of surface and stain designated to be cleaned. Test also to determine the desired surface contact time and any cleanup of new potential for adverse reactions with adjacent materials. Allow test panels to dry thoroughly before evaluating final appearance and results.

Suitable Substrates
All brick, block, tile, stone (real and synthetic), mortar, pre-cast, and concrete brick

- 4:1 is the standard dilution on most surfaces
- 3:1 for etching pre-cast panels

Note: Dilutions will vary based on application and surface to be cleaned

Coverage Rates
Coverage rates will vary from 100-200 sq. ft. per gallon depending on the surface porosity, texture and severity of staining.

Pre-Application Information
Before applying, read “Protect” in the Preparation section and “Precautionary Measures” under Safety Information. Heavy clumps should be removed while chemical soaks on the wall. Use a steel garden edger, carbide block or brick to remove chunks. Scrape after detergent application. Hold the edger at a narrow angle to the wall and use a quick chop to remove the obstruction.

Low Pressure Application
Pre-wet (do not soak) the surface with water. SOS-50 can be applied to a dry wall in cooler temperatures. Apply from the top down. Use an EC Jet or a low pressure sprayer, applying with long, even passes. White foam signals product activation. After initial foam collapse, reapply product without rinsing until there is no further foaming. When cleaning sand faced brick, use more applications at standard dilution, scrape, then rinse carefully at low pressures. Before rinsing, use heavy rubber gloves and rub lightly on a mortar smear. The mortar should crumble easily within five minutes of application. If there are problems removing excess mortar with one application, utilize one of these options: decrease the dilution, scrape more thoroughly, or use two or more applications. Water run-down keeps the wall wet, allowing for a larger work area. Rinse the product down and off the wall as work progresses.

Caution: Do not allow the product to dry on a surface.

Downstream Projection
Downstream projection allows for greater distance using high concentrations. Use an EC Jet when diluting at 4:1. Down stream is useful when dealing with tilt up concrete for removal of construction dirt and an even surface appearance. Always make sure the dilution is set appropriately.

Building surfaces such as glass, anodized aluminum, virtually any kind of brick or block, even limestone, is usually not affected by SOS-50. Follow proper job site conduct and safety precautions. Chances of causing harm when using accepted standard practices is minimal. Elevator doors, some imported stainless steel hardware and some brass coated parts need to be covered.

Pre-Cast Concrete
Dilutions will vary according to surface product. A downstream projection nozzle is appropriate for chemical application. Cleanup entails a uniform building face without surface changes, not removal of mortar smears. Apply a light coat of water from top to bottom just to the point of run (except in the case of tall structures with multiple levels, in which case clean one section at a time). Follow this with a quick, even application of SOS-50.

Etching Pre-Cast Panel
Dilutions and dwell time depend on the desired etch. Test panel etch prior to project. For the brush free method, cut product 3:1 with water. Apply chemical to the surface using a low pressure sprayer. Do not allow product to dry. Wait five to seven minutes to reapply. After another five to seven minutes, rinse using a pressure washer. This will produce the desired etch. The brush free method uses less chemical and water overall. For the brush method on exposed aggregate, cut product 3:1 and apply to wall using low pressure and brush. Apply chemical; brush for approximately five minutes for desired etch.

Rinsing determines the quality of the job. Generalized rules of rinsing would include:

1- Use a wide tip no less than 25 degrees. A 40-degree tip is recommended especially for sand faced or other special brick surfaces to reduce the potential for surface damage. Observe distance from the wall to avoid potential damage to the mortar joints. Rotating zero degree nozzles can do great harm to mortar joints and masonry; keep nozzles well back from surface.
2- Craftsmanship determines the appropriate pressures for rinsing. A thorough rinse job is always recommended, however, our chemistry never requires flooding a wall. Pressures that mark or damage the surface should be avoided. When in doubt, follow the manufacturers recommended P.S.I. for the substrate on which you are working.
3- Always use overlapping passes to achieve a uniform appearance.
4- Always rinse from top down to prevent drying and to combat operator fatigue.

Note: Concrete brick, synthetic masonry and surface dyed substrates need to be rinsed at low pressures (Ex. Standard garden hose with nozzle).


General Application
Always wear goggles and rubber gloves when handling this product. Keep off of skin and clothing. If material comes in contact with clothing, wash before re-use. Do not dilute SOS-50 with any other product except water. Do not use for any other applications other than specified. Do not remove label. Avoid elevator doors as the coating can be affected. Read Material Safety Data Sheet for additional safety and health hazard information prior to use. Do not get in eyes, on skin or clothing. Avoid breathing fumes. Keep container closed when not in use. Use with adequate ventilation. Applicators should wear a rain suit (plastic, rubber or PVC), boots, gloves, face shields and/or goggles to avoid splash to bare skin and eyes. MIOSH/MSHA approved respiration for use with acids if adequate ventilation is unavailable. Though the potential for fuming SOS-50 is minimal, take precautions to avoid exposing building occupants to fumes. Dispose of empty containers according to federal, state, and local requirements. Avoid drifting of material or rinse water onto autos and pedestrians by protecting or diverting such traffic.
