4.4. Product Characteristics: When applied according to the manufacturer's directions over previously unsealed surfaces, the floor sealer shall dry to provide a low luster uniform appearance, sealing the pores of the following by penetration and leaving no apparent surface film. A second coat of sealer when applied over a surface sealed according to the manufacturer's directions, sing the same type material, shall adhere to the previous sealer coat and shall not damage it. The sealer shall exhibit a minimum darkening upon aging.

The floor sealer shall provide a satisfactory foundation from materials such as liquid or paste waxes, synthetic polymer emulsions, or water emulsion waxes, and shall contain no ingredients which might be injurious to the type flooring for which its use is intended under this specification.

6.1. TESTS: The product furnished under this specification shall be tested by the following methods or approved equally applicable procedures:

Federal Test Method Standard No. 141

6.1.1. Non-Volatile: Method No. 4041

6.1.2. Drying Time: Method No. 4061

6.1.3. Water Content: Method No. 4081

6.1.4. Skinning: Method No. 4141

6.1.5. Viscosity: Viscosity shall be determined according to the following methods:

Fill a beaker having a diameter of not less than 2 3/4 inches with an undiluted sample of the sealer. Check the viscosity at the specified temperature using a spindle #1 on a Model LVO or LVF Brookfield Viscometer operating at 60 rpm. Repeat this reading after having again checked the temperature to be certain it is the same. Any other viscometer or method may be used which gives results in absolute units and which can be correlated to the test described above.

6.1.6. Color: Color shall be determined visually.

6.1.7. Water Resistance: Shall be determined according to the following method: Flow a coat of the sealer on a 3 inch x 5 inch sheet of No. 31 gauge bright tin plate previously cleaned with benzene, and let stand in a vertical position at room temperature for 48 hours. The drying should be carried out at a temperature within the range of 70-90 V and a relative humidity of 40-60% saturation. After the drying cycle, test for water resistance using room temperature distilled water as follows: Place one milliliter of distilled water on the center of the coated portion of the panel (lying in a horizontal position) and allow to remain undisturbed for one hour. There should be no softening or separation of the film from the surface of the panel and no more than slight dulling or whitening of the film.

6.1.8. Sealing Characteristics: Shall be determined according to the following method: Apply the floor sealer to a new, unsealed terrazzo panel, with a pad of clean cheese cloth, applying a fairly liberal coat. Permit the sealer to set 15 minutes, to absorb into the surface of the panel. Wipe off the excess sealer remaining on the surface, using a pad of clean cheese cloth. (The excess sealer removed in the manner shall be wiped readily and cleanly from the surface.) Let dry for 24 hours at a temperature between 70-90 F. Then apply a second coat of the sealer in accordance with the procedure indicated above. Let dry for 24 hours. Place a few drops of blue-black writing ink, conforming to Federal Specification TT-I-563e, on the surface of the treated panel at various places and allow to remain for 3 minutes. After taking up the ink with a piece of blotting paper and wiping the spots lightly with a damp cloth, there shall be no indication of the presence of ink. The terrazzo panel shall meet the standards of the National Terrazzo and Mosaic Association, Inc.

6.1.9. pH: ASTM E-70.

6.1.10. Patching: The surface of the panel prepared according to Paragraph 6 (Sealing Characteristics) shall be rubbed with No. 0 steel wool to simulate worn areas. The floor sealer shall be applied over these worn areas according to the manufacturer's directions for patching. When dry, the treated areas shall blend with the surface of the panel without showing lap marks.

Note: Tests and methods of testing shall generally be as listed in the preceding Paragraph 6; however, the Commission reserves the right to use such additional or alternate methods as may be deemed necessary.

7. INSPECTION: Products furnished under this specification shall be inspected by, or at the direction of the Commission and/or the ordering State agency either at the destination or place of manufacture.

8. PACKING / PACKAGING: Packing for shipment shall be in accordance with the manufacturer's standard practice and in a manner readily accepted by common carriers engaged in interstate commerce. Within the shipping carton, units shall be packed in a manner designed to minimize damage during the shipment because of rough or improper handling.

12. PRODUCT INFORMATION:

12.1. Floor sealer furnished to this specification is an emulsion type product and is in the form of a milky white emulsion of resins in a water base. Being a water based emulsion, the floor sealer should be protected from freezing. The water emulsion floor sealer covered by this specification is only intended for use on masonry floors (including terrazzo, marble, etc.) and porous floor tile (as vinyl, asbestos, rubber, etc..). It should never be sued to seal wood floors. For sealing wooden floors, see Texas Specification No. 485-54-04: Floor Sealer and/or Finish, Wood.

12.2. Direction for Use: The manufacturer's label directions for use should always be followed in detail; however, some useful maintenance suggestions are listed below:

(1) Preparing the surface of new and old terrazzo, marble and masonry floors:

(a) New terrazzo, marble, or masonry floors: Scrub the floor thoroughly with a general purpose cleaner-detergent complying with Texas Specification No. 485-16-03 (Paragraph 11) or a low sudsing general purpose cleaner-detergent complying with Texas Specification No. 485-16-05 (Paragraph 11). Rinse well with clear water and let the floor dry at least two (2) hours before applying the sealer.

(b) Old terrazzo, marble, or masonry floors: Wet the floor area down with a general purpose cleaner-detergent complying with Texas Specification No. 485-16-03 (Paragraph 11) or a low sudsing general purpose cleaner-detergent complying with Texas Specification No. 485-16-05 (Paragraph 11). Scrub well with a stiff bristle brush, rinse well with clear water. Over the wetted surface sprinkle a mixture of three (3) parts of abrasive powder and one (1) part of sodium bisulfate, using one pound of the mixed power per one hundred square feet of flooring. Scrub well with a stiff bristle brush. After scrubbing, rinse well with clear water and let the floor dry thoroughly before applying the sealer.

(2) Preparing the surface of new and old porous floor tile (as vinyl-asbestos, rubber, etc.):

(a) New Tile: Scrub the floor thoroughly with a general purpose cleaner detergent complying with Texas Specification No. 485-16-03 (Paragraph 11) or a low sudsing general purpose cleaner detergent complying with Texas Specification No. 485-16-05 (Paragraph 11). Rinse well with clear water and let the floor dry at least two (2) hours before applying the sealer.

(b) Old Tile: (Treated with wax or floor finish and/or floor sealer) Machine strip the floor using the floor stripping concentration of general purpose cleaner detergent complying with Texas Specification No . 485-16-03 (Paragraph 11) or a low sudsing general purpose cleaner detergent complying with Texas Specification No. 485-16-05 (Paragraph 11). The preferred method fro removing the major portion of the stripping detergent and particles of wax or floor finish is by wet vacuum pick-up. If a wet vacuum is not available, then thorough damp mopping can be used to remove the loose particles. rinse thoroughly with clear water until all traces of detergent have been removed. Let the floor dry for at least two (2) hours. After the floor is dry, remove the last traces of particles of wax or floor finish by sweeping or vacuuming. All loose particles must be removed from the floor before applying floor sealer.

(3) Applying sealer to previously prepared masonry or porous tile floors:

Either on new or old substrates, after cleaning (as in 12b (1) or 12b(2)) apply the sealer uniformly with lamb's wool applicator, cotton (or nylon) string mop or roller, using care not to build up or streak the sealer in application. Should two coats be required on porous substrates, apply a second coat in the same manner allowing at least one hour drying between coats.
