BSP

Biological Stain Presoak

Description and Use:
BSP is a clear liquid that has both excellent safety and performance. It has an almost neutral ph and is not caustic in nature. BSP is an excellent fast acting biologic stain remover on limestone substrates. BSP works on limestone and sandstone to soften black mold and mildew stains that also need an acid to clean adequately, and to remove those heavy deposit buildups under ledges and windows.

Advantages:
* Excellent safety and performance.
* Noncorrosive.

Limitations:
* BSP is safe for paint, metal, plants, wood, plastics signs, or glass, but all of these surfaces must be protected from contact with the straight product.

Preparation:

*Protect:
Test and protect adjacent and surrounding surfaces not intended to be cleaned from exposure to the cleaning solution.

*Surface & Air Temperatures:
To avoid harm to masonry, do not clean when temperatures are below freezing or will be overnight. Best cleaning results are obtained when air and masonry surface temperatures are 40 deg. Fahrenheit or above. If freezing conditions exist prior to application, allow adequate time for masonry to thaw.

*Pre-Testing:
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 potential for adverse reactions with adjacent materials. Allow test panels to dry thoroughly before evaluating final appearance and results.

Dilutions:
Use BSP undiluted for most stains or deposits. Note: Dilutions will vary based on application and surface to be cleaned.

Application Instructions:
Apply the product by means of brush, roller, low pressure sprayer. This product is extremely mild and has no caustic at all; normal care should be taken when using it at all times. It is not necessary to cover wood , paint, aluminum, or soft metal or steel trim, but care should be taken not to allow the product to dry on glass. Use BSP undiluted for most stains and deposits. Expected coverage is between 100 and 300 square feet per gallon. Apply the product liberally to the dirty surface. Do not try to spread the product to thin as this will reduce the dwell time and possibly restrict the cleaning action. Agitation with a stiff bristled brush may help on very heavy deposits or stains. The average dwell time needed is ten minutes for stains or a repeated application after ten minutes for heavier deposits. Running a brush over the stain will indicate if the stain is starting to release by showing dirt in the suds. Extreme temperature variations will affect product performance. Do not use the product in extreme cold and if the surface is over 800 Fahrenheit, cool the surface with some water before applying for longer dwell times and better results. To remove the product, use a high pressure rinse. It is important on limestone in particular to neutralize the surface thoroughly after rinsing. Use Sabrestore to neutralize, clean and brighten on limestone, and GS Restoration or HD Acid to neutralize on Sandstone.

Coverage Rates:
Coverage rates will vary from 100 - 300 sq. ft./gal. depending on the surface porosity, texture and severity of staining.
