<br />ensure against failure from crack/joint originated moisture and
<br />reduce pattern transference to the finished flooring product.
<br />Penetrant and coating systems employ fibereal dispersive
<br />membrane to a width sufficient to span control joints.
<br />PART 2 PRODUCTS
<br />2.01 MANUFACTURERS
<br />Subject to compliance with requirements, provide water vapor
<br />emission and alkalinity control system by one of the following:
<br />1. Floor Seal Technology
<br />1005 Ames Avenue
<br />Milpitas, CA 95035
<br />(800) 572-2344
<br />2. Approved Equal - Sub Contractor must prove, in writing, that
<br />substituted material or manufacturer meets or exceeds that of
<br />the product specified.
<br />2.02 Materials
<br />A. Mes & Mes-R penetrant- Mes pentrant is a voc * compliant
<br />water -based modified acrylic epoxy formulation, developed to
<br />penetrate the concrete surface and mechanically restrict the pores
<br />without any dependence on concrete chemistry for successful
<br />reaction. MES does not require more than several hours of curing.
<br />Applied directly over a freshly shot -blasted concrete surface, MES
<br />penetrant ensures subsequent mechanical bonding. MES-R
<br />penetrant is formulated for compatibility with resinous flooring
<br />surfaces.
<br />B. MES & MES-R Coating- MES coating has the same chemical
<br />formulation as MES penetrant, but with a thicker viscosity. It is
<br />used in conjunction with MES penetrant in order ensure a high
<br />tensile strength bond to the slab to suppress volume. Applied
<br />during the tack -up phase or the previous application, the slab
<br />surface then becomes completely encapsulated. MES-R coating is
<br />formulated for compatibility with resinous flooring surfaces.
<br />C. Fiberseal & Fiberseal-R Dispersive Membrane- MES Membrane is a
<br />three- component VOC-Compliant, water -based acrylic copolymer
<br />resin material with a fiber membrane carrier. A fry weave
<br />membrane is laminated to the pervious surface material, allowed to
<br />cure, and surfaced with a high density acrylic copolymer and
<br />modified -epoxy finish layer. Fiberseal membrane creates a high
<br />static vapor pressure through its mechanical properties, and buffers
<br />the environmental forces that drive moisture emission. Fiberseal-R
<br />is formulated for compatibility with resinous flooring surfaces.
<br />D. MES & MES-R Membrane MES membrane is a three -component,
<br />VOC-compliant, antimicrobial, water -based, modified acrylic epoxy
<br />formulation. Developed strictly to enhance the saturation capability
<br />of the fiberseal dispersive membrane system. MES membrane
<br />contains a silicated additive which provides more physical capacity
<br />to the suppressive properties of MES-Coating. In cases of high
<br />vapor emission, membranes can become critically -saturated. MES
<br />membrane allows a further layer of diffusion to avoid saturation.
<br />MES-R membrane is formulated for compatibility with resinous
<br />flooring surfacea.
<br />E. Cementitious Surfaces- All Floor Seal Technology treatments are
<br />finished with 100% Portland -based cementitious compound for all
<br />finished floor products (expect resinous coatings). The
<br />cementitious surface finish ensures compatibility with all types of
<br />floor covering adhesives. Floor Seal Technology concrete vapor
<br />emission & alkalinity control systems provide the floor covering
<br />contractor with a cementitious surface that is ready to receive a
<br />finished floor covering with minimal surface preparation.
