Applications & Uses
- Markets
- Applications
- Application Area
- Limitations
- Not generally effective in removal of atmospheric stains and black carbon found on older masonry surfaces. Use the appropriate Sure Klean® restoration cleaner to remove atmospheric staining from older masonry surfaces.
- Not for use on polished natural stone.
- May damage treated low-E glass; acrylic and polycarbonate sheet glazing; and glazing with surface-applied reflective, metallic or other synthetic coatings and films. Always test for adverse effects prior to overall application. If testing is not feasible or indicates adverse effects, such substrates must be protected.
- Preparation
Clean masonry before installing non-masonry materials such as windows, doors, finished flooring, metal fixtures, hardware, light fixtures, roofing materials, etc. that the cleaner could harm. If cleaning is to be completed after installation of non-masonry materials not intended for treatment or exposure to 101 Lime Solvent®, test all substrates not intended to be treated with 101 Lime Solvent® before full scale application. If testing is not feasible or indicates adverse effects, protect substrates from product splash, rinse, wind drift and fumes with Sure Klean® Strippable Masking or polyethylene prior to application.
All caulking and sealant materials should be in place and thoroughly cured before cleaning.
When applying to the exteriors of occupied buildings, make sure all windows, exterior intake and air conditioning vents are covered and air handling equipment is shut down during application.
Construction soiling and mortar residues on new brick and tile surfaces clean most effectively if the cleaning is done within 14–28 days of installation. Mortar and grout smears left on the surface longer result in a more difficult clean down and may cause undesirable results. Cleaning high-strength mortar/ grout within seven days improves results.
The presence of excessive moisture in the wall contributes to efflorescence and other staining. Always protect open wall cavities from rain during construction.
When working over traffic, clean when traffic is at a minimum. Protect or divert traffic if necessary.
Surface and Air Temperatures
Best air and masonry temperatures for cleaning are 40°F (4°C) or above. Cleaning when temperatures are below freezing or will be overnight may harm masonry. If freezing conditions exist before application, let masonry thaw first.
Equipment
Apply with low-pressure (50 psi max) spray or densely-packed, soft-fibered masonry washing brush. Do not atomize. Do not apply with pressure spray above 50 psi. This drives the chemicals deep into the surface, making complete rinse difficult.
Use acid-resistant rigging and safety equipment. Test spray equipment for compatibility and 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 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:
Dilute 101 Lime Solvent® with 4 - 8 parts clean water to one part concentrate, based on test results. Always pour cold water into empty bucket first, then carefully add product. Never use hot water.
Always test to the final dilution that cleans best. More porous masonry and high-strength mortar/ grout will require stronger solutions. Clean glazed surfaces with the mildest solution possible to avoid harm.
Do not alter or mix with chlorine-type bleaches or other chemicals (may release toxic gasses).
Handle in high-density polyethylene or polypropylene containers only. No metal. Acidic materials and fumes attack metal.
Application Instructions:
Test thoroughly before cleaning. Provide adequate ventilation. Caution: Multiple applications may affect the mortar color.
Exterior Surfaces
- Working from the bottom to the top, prewet a large area with fresh water.
- Apply the diluted solution freely from the bottom of the work area up.
- Let cleaning solution stay on the wall for 1 - 3 minutes. Do not let cleaner dry into the masonry. This may leave residue and stains. Fresh-water rinse the surfaces below areas being cleaned to prevent streaking.
- Immediately reapply cleaning solution and scrape off heavy buildup of excess mortar using a wooden scraper or piece of brick. Take care not to harm the masonry surface.
- Working from the bottom of the work area to the top, rinse thoroughly with fresh water, removing all cleaning compound, free sand, loose material and debris.
- Reapply as required following steps 1 through 5.
Interior Surfaces
Proper ventilation is necessary. Test thoroughly. Follow preceding preparation and cleaning procedures for exteriors. Rinse thoroughly with fresh water using a sponge or soft-fibered brush. If there isn’t enough water for complete rinsing, use 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 surface 3 - 5 minutes.
- Apply final rinse of clear water.
Cleanup:
Clean tools and equipment using fresh water.
- Best Practices
Construction soiling and mortar residues on new brick and tile surfaces clean most effectively if the cleaning is done within 14 - 28 days of installation. Mortar and grout smears left on the surface longer result in a more difficult clean down and may cause undesirable results. Cleaning high-strength mortar/ grout within 7 days improves results.
The presence of excessive moisture in the wall contributes to efflorescence and other staining. Always protect open wall cavities from rain during construction.
Do not apply with pressure spray above 50 psi. This drives the chemicals deep into the surface, making complete rinse difficult. Test spray equipment for compatibility and 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.
- Metallic Discoloration
Certain types of light or dark-colored brick and structural tile surfaces may be subject to metallic discolorations. If discolorations are apparent in the stone or brick areas before or after testing, test Sure Klean® Vana Trol® on the masonry surface. Follow the procedures and dilutions on the Vana Trol® label and Product Data Sheet.
