Submittals
General:
Submit manufacturer’s certification that proposed materials, details and systems as indicated and specified fully comply with manufacturer’s details and specifications. If any portion of Contract Documents do not conform to manufacturer’s standard recommendations, submit notification of portions of design that are at variance with manufacturer’s specifications.
Product Data:
Submit manufacturer’s literature, installation instructions and MSDS for each product.
Concrete Slab Test Results:
Submit slab moisture test results. Testing conducted in accordance with ASTM F1869 and / or ASTM F 2170.
Quality Assurance
Manufacturer Qualifications:
Company specializing in manufacturing floor sealing and floor leveling materials that will upon application and inspection of installation, provide a five year warranty that moisture emission will not exceed three pounds per 1000 square feet per 24 hours (from a maximum initial level of 8 lbs.).
Installer Qualifications:
Contractor shall be knowledgeable and well trained with regards to subfloor preparation, including surface preparation, and material application.
Delivery, Storage and Handling
Deliver and store in a dry, well ventilated area at minimum 50 deg. F (10 deg C) and maximum 90 deg F (32 deg C).
Deliver materials in manufacturer’s unopened containers, fully identified with brand, type, grade, class and all other qualifying information. Provide Materials Safety Data Sheets for each product.
System Requirements
Coordinate floor sealing installation with other trades.
Provide materials and accessories in timely manner so as not to delay Work.
Project Conditions
Surfaces to be sealed should have a minimum temperature of 55 deg F. The area should be conditioned at 70 deg F with a maximum humidity of 60% for 48 hours prior to application.
Once applied, the area must be kept at 70 deg F and 60% relative humidity for 72 hours.

Materials
Concrete Floor Sealer – single component, high density, latex based product:
Product: CUTDOWN
Part 3 – Execution
Examination
Examine all construction substrates and conditions under which concrete floor sealer material is to be installed. Do not proceed with the concrete floor sealer installation until unsatisfactory conditions are corrected.
Preparation
Protect adjacent surfaces not designated to receive concrete floor sealer.
Substrate preparation:
All surfaces to be treated must be sound, solid, clean and absorptive. Substrate must be clean and free of any dirt, paint, curing compound, sealer or any other contaminant that might interfere with the product’s penetration and bond. Make sure there is no standing water. Damp mopping is acceptable to remove dust and help prime porous substrates.
Polished or very smooth concrete slabs should be mechanically profiled to allow the material to soak into the pores and properly bond to the slab. Preparation methods include grinding, scarifying, or bead blasting.
For installation of dimensionally unstable floor covering, such as glued down wood floor, the concrete should be prepared by shotblasting to a minimum profile of CSP 3.
When installing a self-leveling material over CUTDOWN follow the surface preparation guidelines for that material for the concrete substrate.
Installation
Mechanically mix concrete floor sealer prior to use.
Apply concrete floor sealer material in quantities and in manner set forth in manufacturer’s full written directions, technical bulletins and recommendations.
Spread using roller (3/8" nap for most substrates) to the dry substrate. Avoid pouring the material directly on the substrate, instead dip into pail or pour the material into a paint pan. Roll with even and consistent strokes to ensure uniform coverage. Be careful to avoid material build-up where the product overlaps.
Allow 2 –3 hour dry time in between coats.
Apply the second coat in the direction perpendicular to the first. Allow 24 hours, at recommended atmospheric conditions, prior to patch or floor covering application.
Where specified install floor covering as per manufacturer’s directions and recommendations. If the surface is irregular and smoothing is required use a suitable hydraulic cement repair material such as DEPENDABLE SKIMCRETE XL or SKIMFLOW ES after the CUTDOWN treatment.
Acceptance
Remove left over materials and any foreign material resulting from the work from the site.
Clean adjacent surfaces and materials.
Precautions / Limitations
Do not nail into CUTDOWN.
Do not apply over existing coatings or floor coverings.
Not recommended where high alkalinity exists.
