- Will not correct damage caused by improper use of hydrofluoric acid cleaning solutions.
- Acidic contents and fumes may damage non masonry and acid-sensitive surfaces.
- Preparation
Sure Klean® 800 Stain Remover is corrosive, etches glass and architectural aluminum and is harmful to wood, painted surfaces and foliage. Beware of wind drift. Fumes will also cause damage. Maintain enough ventilation to avoid buildup of potentially damaging fumes.
Protect people, vehicles, property, plants, metal, all non masonry and acid-sensitive surfaces from contact with cleaner, rinse residue, fumes and wind drift. Protect and/or divert auto and pedestrian traffic.
Clean masonry before installing windows, doors, finished flooring, metal fixtures, hardware, light fixtures, roofing materials and other non masonry items. If already installed, protect with polyethylene. Sure Klean® Strippable Masking is appropriate for use with this product to protect windows.
All caulking and sealant materials should be in place and thoroughly cured before cleaning.
Avoid exposing building occupants to fumes. On occupied buildings, cover all windows, air intakes and exterior air conditioning vents. Shut down air handling equipment during cleaning and until surfaces are thoroughly dry. Use fans and supplemental ventilation when applying on interior surfaces. Maintain ventilation until surfaces are thoroughly dry. Fumes attack glass, metal and all other acid-sensitive surfaces.
Before removing metallic stains (vanadium), the masonry should be thoroughly dry to reduce recurrence of stains after cleaning.
Surface and Air Temperature
For best results, clean when air and masonry surface temperatures are 40°F (4°C) or above. Cleaning when temperatures are below freezing or will be overnight may harm masonry. If freezing conditions have existed, let the masonry thaw before cleaning.
Equipment
Apply with low-pressure (50 psi max) spray or densely-packed, soft-fibered masonry washing brush. Fit equipment with acid-resistant hoses and gaskets to avoid discoloration.
Rinse with enough water and pressure to flush spent cleaner and dissolved soiling from the masonry surface and surface pores without damage. Inadequate rinsing leaves residues which may stain the cleaned surface.
Masonry-washing equipment generating 400 - 1000 psi with a water flow rate of 6 - 8 gallons per minute is the best water/pressure combination for rinsing porous masonry. Use a 15 - 45° fan spray tip. Heated water (150 - 180°F; 65 - 82°C) may improve cleaning efficiency. Use adjustable equipment for reducing water flow-rates and rinsing pressure as needed for sensitive surfaces.
Rinsing pressures greater than 1000 psi and fan spray tips smaller than 15° may permanently damage sensitive masonry. Water flow-rates less than 6 gallons per minute may reduce cleaning productivity and contribute to uneven cleaning results.
- Application
Read “Preparation” and the Safety Data Sheet before use. Always test a small area (minimum 4-ft x 4-ft) of each surface to confirm suitability and desired results before beginning overall application. Test each type of masonry and each type of stain. Test with the same equipment, recommended surface preparation and application procedures planned for general application. Let test area dry 3 - 7 days before inspection and approval. Make the test panel available for comparison throughout the cleaning project.
Dilution
Use in concentrate for most applications. Testing indicates if 800 Stain Remover may be diluted with equal parts water.
Always pour cold water into empty bucket first, then carefully add product. Never use hot water. Handle in polypropylene buckets only. Acidic materials and fumes attack metal.
Typical Coverage Rates
Reference the substrate chart on page 2. The coverage rate chart assumes an average coverage rate of 100 square feet per gallon of prepared cleaner. When calculating the volume of cleaner required for porous, textured surfaces, assume 50 square feet per gallon of prepared cleaner. For dense, smooth surfaces, assume up to 150 square feet per gallon of prepared cleaner.
Exterior Surfaces
- Working from the bottom to the top, prewet the masonry surface with clean water.
- Apply directly to the masonry surface from the bottom of the work area to the top.
- Let the cleaner stay on the surface for 3 - 5 minutes or until stains are gone. If treated surfaces are left unattended, keep people away from cleaner. Note: Do not let cleaner dry into the surface. If surface begins to dry in less than 5 minutes, water-rinse and reapply cleaner.
- Working from the bottom of the work area to the top, reapply cleaner and rinse with fresh water. Thorough rinsing gets all residues off the surface. Older, more delicate masonry may require less water pressure to avoid damage. Avoid multiple applications. If pressure rinsing equipment is not available, rinse thoroughly with clean water, brushing the wall while rinsing.
Interior Surfaces
Test and follow cleaning procedure for exterior surfaces. Rinse thoroughly with fresh water using a sponge or soft-fibered brush.
If conditions do not allow enough water for complete rinsing, use a neutralizing rinse following this procedure:
- Rinse with clear water.
- Apply neutralizing rinse of 2 ounces baking soda to 1 gallon water.
- Saturate. Leave solution on the surface 3 - 5 minutes.
- Apply final rinse of clear water.
Cleanup
Clean tools and equipment using fresh water.
- Best Practices
Before removing metallic stains (vanadium), the masonry should be thoroughly dry to reduce recurrence of stains after cleaning.
Rinse with enough water and pressure to flush spent cleaner and dissolved soiling from the masonry surface and surface pores without damage. Inadequate rinsing leaves residues which may stain the cleaned surface.
Always pour cold water into empty bucket first, then carefully add product. Never use hot water. Handle in polypropylene buckets only. Acidic materials and fumes attack metal.
