Following general hygiene considerations are recognized as common good industrial practices.While Crystal Lok® may present no obvious hazard to health or environment, there are some general hygiene considerations that are practiced by industry and are generally applicable to industrial situations. such considerations may include; Avoid breathing vapor or dust. Avoid contact with eyes and skin. Wash thoroughly after handling and before eating and drinking.Preparation of concrete surfaces may cause hazardous conditions. If you scrape, sand, or remove rust or old paint, you may release lead dust. Lead is toxic. Exposure to lead dust can cause serious illness, such as brain damage,especially in children. Pregnant women should also avoid exposure. Wear a NIOSH approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead. These general hygiene considerations are not material specific. They are placed here to avoid diminishing the importance of the material specific recommendations.

Section 12: Ecological Information

Sinks and mixes with water. High pH is harmful to aquatic life. This material is not persistent in aquatic systems. Diluted material rapidly depolymerizes to yield dissolved silica that is indistinguishable from natural dissolved silica. Does not bioaccumulate except in species that use silica as a structural material such as diatoms and siliceous sponges. Where abnormally low natural silica concentrations exist (less than 0.1 ppm), dissolved silica may be a limiting nutrient for diatoms and a few other aquatic algal species. However, the addition of excess dissolved silica over the limiting concentration will not stimulate the growth of diatom populations; their growth rate is independent of silica concentration once the limiting concentration is exceeded. Neither silica nor sodium will appreciably bioconcentrate up the food chain. See Section 2 - Hazards Identification and Section 6: Accidental Release Measures.

Crystal Lok® container label text:

DIRECTIONS FOR USE

CRYSTAL-LOK® is for use within Portland cement based structural grade concrete walls, floors, roofs and roof tiles, block, pipe, beams, concrete paver bricks; Portland mortar, stucco, gunite, etc.

SURFACE PREPARATION:

Apply CRYSTAL-LOK® onto concrete above or below grade, that is free of paint, wax, oil, dirt and dust. Remove any previous sealer or paint before applying CRYSTAL-LOK®. Surface must absorb CRYSTAL-LOK® to be effective. May be applied onto wet surface but not onto standing or running water. Apply when temperature is 35°F. and rising or 110°F. and falling. Apply water onto hot concrete to cool surface and break surface tension.

APPLICATION:

Do not thin. Mix thoroughly before using and keep agitated. Apply with airless sprayer with extender, paint sprayer, garden pump sprayer, brush or roller. Apply at 300-200 square feet per gallon (27.9-18.6 square meters per gallon). Coverage rate depends on the surface porosity of the concrete. Rinse the surface with water after application whenever possible. Surface ponding creates bonded residual white crystalline C-S-H cement. Sweep or rinse while wet to remove ponding. Will etch glass and aluminum surfaces on contact. Walk on when no longer damp. Cure at 24 hours. Shelf life is indefinite. Avoid freezing. Not intended for Clay Tiles or Clay Brick. Store in plastic or stainless steel containers, not in aluminum containers.

See www.crystal-lok.com for Product information, Technical Data and MSDS.

WARRANTY:

Manufacturer’s liability is limited to the replacement or refund of purchase price.

CAUTION:

pH 11.5 alkaline. Avoid contact with skin and eyes. In case of contact, flush immediately with plenty of water. If irritation continues, call a physician. If swallowed, do not induce vomiting. Call a physician.KEEP OUT OF REACH OF CHILDREN.
