3. PRODUCT DESCRIPTION
Basic Use: Crete-Lease Bio-Tru permits easy stain-free removal of forms, formliners, pallets, etc. from hardened concrete. It:

Is a soy based product
Sprays from 20° to 120°F
No Haz-Mat requirement for product, driver or truck
Meets biodegradability regulations
Cuts form clean-up time up to 70% when properly applied
Can reduce bugholes on concrete surfaces
Doesn't interfere with adhesion of caulk, architectural coatings, paint, sealers and curing compounds on cured concrete surfaces when properly applied
Reduces incidences of skin rashes to an absolute minimum

Limitations: a) Not recommended for forms or formliners made from expanded polystyrene, SBR, or natural rubber or latexes made of these. Use Crete-Lease 20-VOC for expanded polystyrene. b) Although subfreezing temperatures have no effect on the releasing action of Crete-Lease Bio-Tru, temperatures below freezing promote film thicknesses which do cause more bugholes.

Ground Shipping in the USA: Containers holding 55 gallons or 5 gallons or less (regardless of the number of containers) are not federally regulated and shipping product in the Cresset package does not require following hazardous shipping requirements.

Applicable Standards: Crete-Lease Bio-Tru Release Agent meets U.S. Army, Corps of Engineers CE-204, Section 7.10 and CE 1401.01, Section 17.4.

5. APPLICATION
Preparatory Work: Form surfaces must be clean, dry and free from contaminants. Apply Crete-Lease just minutes before concrete is placed or up to 14 days before if treated surface is protected.

Methods: Your choice of application methods will determine the final appearance of the concrete. Use Release Method when a form release is primary concern; use a Visual Guide Specification for concrete where both visual impact and form reuse are primary concerns.

Release Method: Apply with any type applicator or technique. Use a sprayer, roller, brush, or mop.

Too much release agent will cause bugholes and "wormtracks" (as seen in CCS 6), and an increased difficulty in stripping.

Dilution with fuel oil, diesel fuels, or mineral spirits will promote an increase in stripping difficulties, concrete build-up, bugholes, soft spots, and staining.

Visual Guide Specifications: Cresset Concrete Standard 3 (CCS 3)is typical of Crete-Lease Bio-Tru. CCS 2 is attainable when coverage rates are carefully followed. See Spray Coverage Rates Chart for specification details.

Visual Guide Specification Notes:
1. With Crete-Lease Bio-Tru, the thinner the film the better the appearance, plus the forms strip easier.

2. Form surfaces used in producing CCS 1 and CCS 2 must be as clean as the hood on a showroom car before the release agent is applied. Protect treated surfaces from precipitation, dust and debris.

3. Non-porous form surfaces are required to uniformly produce CCS 1, CCS 2 and CCS 3. Examples include HDO plywood, elastomerics, all plastics, metals, and coatings.

4. Thin spray applications of release agent at temperatures below 45°F are produced by increasing spray pressure about 10 psi.

Storage: Factory sealed containers will keep up to 2 years at temperatures from -20°F to 140°F (-30°C to 60°C). Crete-Lease Bio-Tru is a class 3A liquid for purposes of meeting OSHA storage requirements (Section 1910.106).

Store drums horizontally or in a position to prevent standing water from collecting over the bungs.

Precautions: Keep out of reach of children. Avoid prolonged contact with the skin. Use with adequate ventilation. See Material Safety Data Sheet for additional information.

SPRAY COVERAGE RATES TO OBTAIN HIGH VISUAL IMPACT CONCRETE

`Flat Spray Tip`	`Pressure`	`Optimum Coverage For` CCS 2	`Optimum Coverage For` CCS 3
`8001 tip`	`30-40 psi`	`40 sq ft/10 sec`	`20 sq ft/10 sec`
`800067 fine tip`	`50-60 psi`	`35 sq ft/10 sec`	`15 sq ft/10 sec`
`800050 fine tip`	`50-60 psi`	`25 sq ft/10 sec`	`12 sq ft/10 sec`
`Typical Wet Film Thickness`		`0.0005 to 0.001 in`	`0.001 to 0.0025 in`

Notes: 1. The coverage rates are for smooth non-porous forms.
2. Distance between form and spray tip is constant; typically between 12 and 18 inches.
