SKMSCG (1 Gallon)

Coverage rates will vary with substrate quality and porosity. Estimated coverage rate is 50 sq.ft. per gallon of diluted cleaner. Always test.

Protect people, vehicles, property, metal, painted
surfaces, plants and other non masonry materials
from product, splash, residue, rinse, wind drift and
fumes. When working over traffic, clean when
traffic is at a minimum. Protect or divert traffic if
necessary.
The accent color found on many types of
manufactured stone is sensitive to any cleaning
operation. To limit the potential for loss of accent
color, minimize the accumulation of excess mortar
on the face of the manufactured stone. Avoid
bonding agents whenever practical as they make
excess mortar more difficult to remove without
loss of applied accent colors. Clean carefully as
you go using fresh water and a soft brush.
Remove mortar residues and construction soiling
with Manufactured Stone Cleaner within 7–14
days of tooling the mortar joints. Clean before
installing windows, doors, finished flooring, metal
fixtures, hardware, light fixtures, roofing materials
and other non masonry items whenever possible.
If these items are already installed, protect with
polyethylene before application. All caulking
and sealant materials should be in place and
thoroughly cured before cleaning.
When applying to exteriors of occupied buildings,
make sure all windows, exterior intakes and air
conditioning vents are covered and air handling
equipment are shut down during application.

Equipment
Apply with a soft-fibered, tampico masonry washing brush or with low-pressure spray equipment fitted with acid-resistant hoses and gaskets. Don’t use pressure spray above 50 psi. This drives the cleaner into the surface, making rinse difficult. May cause stains.

Dilution and application equipment should be of polypropylene or polyethylene construction. Use acid-resistant staging equipment and safety lines.

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.

Rinsing pressures greater than 400 psi and fan spray tips smaller than 15° may permanently damage sensitive manufactured stone

APPLICATION
ALWAYS TEST each surface and type of stain for suitability, dilution and results before overall application. Apply according to the following procedures. Let surface dry thoroughly before inspection and approval.

Dilute 1 part concentrate to 3 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. Do not alter or dilute product except as specified.

Application Instructions
Multiple applications may etch acid-sensitive surfaces.
1. Working from bottom to top, lightly pre-wet the manufactured stone before applying the cleaner. Keep lower areas wet to avoid streaks.
2. Working from the bottom to the top, gently apply diluted cleaner directly to surface with masonry brush or low-pressure spray.
3. Let the cleaner stay on the surface for 3–5 minutes or until stains have disappeared.
4. Reapply cleaner and rinse thoroughly with fresh water, working from the bottom to the top to get all residues off the surface. Use only enough water to remove the spent cleaner and dissolved soiling from the surface. If tests show that pressure rinsing equipment can be used without removing color, do not exceed 400 psi. If pressure rinsing equipment is not available, brush the surface gently while rinsing with clean water.

Clean up: Clean tools and equipment using fresh water.
