Basic Use: Crete-Lease 880 releases any kind of form or formliner (except expanded polystyrene) from hardened concrete. Forms and formliners strip easily and cleanly. Crete- Lease 880 also helps eliminate bugholes and stains.
Use Crete-Lease 880 on pallets and equipment that contact concrete. It also provides rust protection for steel forms and equipment. It:

Form surfaces must be extremely clean to produce architectural surfaces CCS 1, CCS 2 and CCS 3. Even very small amounts of buildup, dust or debris show on the final surface. Use only non-porous form and formliner surfaces to achieve CCS 1, CCS 2 and CCS 3 concrete surfaces.
Apply Crete-Lease 880 about 20 minutes before placing concrete, or up to 14 days before if treated surfaces are protected from dust and debris.
Dilution: Use as is...any dilution with fuel oil, diesel fuels, or mineral spirits promotes an increase in stripping difficulties, concrete build-up, bugholes, soft spots, and staining.
Non-porous form surfaces are critical to achieve CCS 1.
A) Wipe on an ultra thin film of Crete-Lease 880 Release Agent with a clean, soft flannel cloth that is moist, not wet, with release agent. Wipe out “brush strokes”.
B) Spray textured form or formliners then “wipe off” with a clean, soft flannel cloth that is moist, not wet, with Crete-Lease 880 Release Agent.
Properly executed, either procedure produces an ultra thin film of Crete-Lease 880 Release Agent less than 0.0005 inch... about 1/3 as thick as a human hair. This ultra thin film helps produce bughole-free concrete surfaces without stains and without problems of adhesion of caulk or other coatings. Forms strip cleanly and easily.
Spray Crete-Lease 880 in an ultra thin film from 0.0005 to 0.001 inch thick. Hold the spray tip 12 to 18 inches from the form.
CCS 2 requires the use of non-porous forms and formliners. Only spray with flat spray tips...8001 or 800067. Adjust pressure to provide a flow rate through the spray tip of about 12 ounces per minute for the 8001 spray tip and 10 ounces per minute for the 800067 spray tip.
Spray apply Crete-Lease 880 in a thin film from 0.001 to 0.0025 inch thick. Use non-porous form surfaces to produce CCS 3. Use flat spray tips 8001 or 800067.
Spray Crete-Lease 880 in a film from 0.0025 to 0.0045 inch thick. Use any form or formliner, including any grade of plywood. Flat spray tip 8001 or 800067 are recommended.
Spray apply Crete-Lease Release Agent from 0.0045 to 0.0065 inch thick. Use any type of form.
Apply Crete-Lease Release Agent in the fastest, most convenient way.

Standards on Concrete Finishes
CCS is a photographic guide to help you specify high quality architectural concrete surfaces. Using the guide, you choose the concrete surface you want when you’re writing contract documents and specifications. A tool to get agreement with all involved in the project... ahead of time.
