GENERAL
The work performed under this section includes the surface preparation and application of protective floor coatings. This document is intended to provide the specifying engineer/architect a comprehensive tool to accurately call for the substrate preparation, product application, and product selection for a medium-duty industrial floor coating.
CONTRACTOR
All work shall be performed by skilled craftsmen qualified to perform the required work in a manner equal to the best standards and practices. It is highly recommended that the foreman or supervisor be trained and certified by the Product Manufacturer.
Contractor shall provide a supervisor at the work site during surface preparation and coating application operations. Supervisor shall have the authority to sign change orders, coordinate work and make decisions pertaining to the fulfillment of the contract.
SUBSTRATE CHARACTERISTICS
New concrete should be cured per ACI-308-81, (R-1986), Recommended Practice for Curing Concrete. Additives used in concrete to improve physical properties, adjust flow or slump, or accelerate cure time typically do not interfere with the adhesion of thermoset flooring systems after proper substrate preparation.
"Type 1" new concrete should have a minimum of twenty-eight (28) days cure at an average temperature
of 73 degrees F prior to the application of the floor coating. The substrate shall have a minimum of 2500 psi compressive strength or at least a 200 psi tensile strength.
The optimum finish for a concrete surface that is to receive a polymer floor coating is wood floating with one pass with a steel trowel. This procedure provides a surface that is relatively free of defects with the least amount of surface laitance. Excessive troweling or power troweling can result in greater amounts of laitance brought to the
surface, resulting in difficulty during preparation.
SUBSTRATE PREPARATION
The bonding capability of any polymer floor coating is dependent upon proper substrate preparation. Preparation will many times be determined by the type and accessibility of the application area. In some cases mechanical methods will be required to prepare or to remove contaminated concrete, and in others chemically treating the substrate will be sufficient.
ASTM D-4258 and/or ASTM D-4261 should be utilized prior to the application of any floor coating. Substrate cleaning/preparation is intended to provide a properly profiled, contaminate-free surface suitable for floor coating application.
When grease and oil deposits are present, a cleaner/degreaser should be utilized prior to the main prep operation. Follow the degreasing operation with a thorough flushing of fresh water.
Note: By applying an acid solution as per ASTM D-4260 the success of the prior operation can be checked. If a vigorous acting uniform haze of bubbles appears, the degreasing operation was successful. If only weak bubbles form, concrete contamination is still present requiring another cleaning and etching step. If little or no bubbles form after the second operation, mechanical means of preparation will be required.
The concrete surface shall be prepared by chemical and/or mechanical means, as dictated by jobsite accessibility or as specified by the Facilities Engineer.
Mechanical preparation methods shall conform to ASTM D4259, Sections 6 (Mechanical Abrading Procedure), 7 (Water Blast Cleaning) or 8 (Abrasive Blast Cleaning Procedures).
Note: Section 8, the Abrasive Blast Cleaning Procedure is the preferred method of preparing floor surfaces prior to coating, whenever practical. The use of a portable shotblasting machine, such as a Blastrac, is recommended.
If chemical preparation is to be used, it should comply with ASTM D-4260. Dilute the acid, one gallon acid to one gallon water and apply at a maximum spreading rate of 2 gallons of mixture per 100 square feet to obtain a total wetting of the surface. The solution shall be worked into the surface of the concrete by stiff bristles brushes until the bubbling action has subsided. After the chemical preparation is completed and thoroughly washed from the surface, a texture similar to that of 60-80 grit sandpaper should be present If it is not, the chemical etching process must be repeated After the surface has been thoroughly washed and neutralized, test for neutral pH with litmus paper.
CONCRETE REPAIR
When a significant amount of concrete removal is required during preparation (Typically depths of 1/2 inches or greater), polymer or cementitious based repair materials should be utilized to provide high performance fills. Repair materials may include the following:
Perma Grout E (ChemProof Polymers Epoxy Grout)
Other acceptable materials recommended by ChemProof Polymers
PRODUCTS GENERAL
PERMACOAT 3000, PERMACOAT 4000, and PERMACOAT 5000 as manufactured by ChemProof Polymers, Inc., of Tulsa, Oklahoma is/are the floor coatings evaluated for this service.
Contractor may request approval for substitute materials in writing from the Engineer, within five days after awarding the contract.
No request for substitutions will be considered which decreases volume solids content, film thickness designation and/or numbers of coats to be applied, or which offers a change in the generic type of coating specified.
All costs for testing and analyzing of proposed substitute materials by independent laboratories shall be paid for by the Contractor.
The coating material shall be of a 100% reactive solids composition, releasing no volatile fumes before, during or after the application process.
The coating shall provide a 100% non-porous system.
The coating shall be insensitive to environmental conditions such as 100% humidity.
The coating shall be essentially odorless before, during, and after the application process.
