Armstrong Standard Excelon Imperial Texture: Grayed Blue Vinyl Composite Tile 51874

• Concrete
• Approved Suspended Wood
• Steel, Stainless Steel, Aluminum, Lead, Copper, Brass, Bronze
• Ceramic Tile, Terrazzo, Marble
• Polymeric Poured (seamless) Floors

• Existing Resilient Sheet Floors
• Vinyl Composition, Vinyl Asbestos, Asphalt, Rubber and Vinyl Tile-on Grade or Suspended Only

• Substrates must be dry, clean, smooth and free from paint, varnish, wax, oils, solvents and other foreign matter. In renovation or remodel work, remove any existing adhesive residue* so that no ridges or puddles are evident and a thin, smooth film remains.
• When using S-230, remove any existing adhesive residue* so that 80% of the overall area of the original substrate is exposed. If these requirements are not followed, curled and/or loose tile could result. For Tile-On, remove wax or other finishes with a commercially available liquid wax stripper. Replace or repair indented or otherwise damaged areas.
• Allow all flooring materials and adhesives to condition to the room temperature a minimum of 48 hours before starting the installation.
• The area to receive resilient flooring should be maintained at a minimum of 65°F (18°C) and a maximum of 100°F (38°C) for 48 hours before, during and for 48 hours after completion. When using S-230 Epoxy Adhesive the maximum room temperature should not exceed 85°F (29°C).
• During the service life of the floor the temperature should never fall below 55°F (13°C). The performance of the flooring material and adhesives can be adversely affected below this minimum temperature.
• Conduct calcium chloride tests or percent relative humidity tests. Bond Tests should also be conducted for compatibility with the substrate. Please refer to Chapter IV, Subfloors and Underlayments.
• Radiant-heated substrates must not exceed a maximum surface temperature of 85°F (29°C).
• Concrete floors should be tested for alkalinity. The allowable readings for the installation of Armstrong flooring are 5 to 9 on the pH scale.

*Some previously manufactured asphaltic "cutback" adhesives contained asbestos (see warning statement on page xii). For removal instructions, refer to the Resilient Floor Covering Institutes's publication Recommended Work Practices for Removal of Resilient Floor Coverings.

1. Line off entire area to be installed.
2. Apply the adhesive over the area not covering the chalk lines and using the fine notching of the S-891 Trowel. You may prefer to spread and install one quarter of the room at a time.
3. Allow the adhesive to set until dry-to-touch (except for S-230) following the recommended open time. To test, press your thumb lightly on the surface of the adhesive in several places. IF the surface feels slightly tacky as your thumb is drawn away and does not stick to your thumb, the adhesive is ready for the installation.
4. Install the tile along the chalk lines, laying the field area first and then fitting in the border tile.
5. Roll all residential tile and SAFTEY ZONE in both directions within the adhesive working time using a 100-lb. roller.
6. Clean adhesive from the surface of the tile using a clean white cloth dampened with a neutral detergent and water.
7. Tile should not be exposed to rolling load traffic for at least 72 hours after installation to allow setting and drying of the adhesive.

1. Line off entire area to be installed.
2. Move chalk lines to one corner or end of the area farthest from the doorway. These lines should be two or three feet from the wall depending on your reach.
3. Remove the bottom of S-230 cans Part A and Part B with a can opener. Mix entire contents of Part A and Part B together with a stirring motion while at the same time lifting from the bottom. Mix thoroughly for 3 to 5 minutes to a uniform color. Do not over mix. Never mix S-230 Adhesive on the subfloor surface.
4. Immediately pour the entire unit of mixed adhesive onto the subfloor. Do not leave mixed adhesive in cans because it shortens pot life and working time, and may generate excessive heat. Maximum pot life of the S-230 Adhesive is approximately 10 minutes depending on temperature and atmospheric conditions.
5. Apply S-230 Adhesive for only two or three rows of tile (Fig. 3). Working time of S-230 is approximately one hour.
6. Tile may be placed into the adhesive immediately, but allowing a 15–20 minute open time and fitting border tile tightly will reduce tile shifting and adhesive oozing. Do not allow the adhesive to dry completely.
7. Install tile with the arrows on the back of the tile pointing in the same direction.
8. Roll tile in both directions within one hour of spreading S-230 Adhesive using a 100-lb. roller. Re-roll one hour later in both directions. Remove adhesive residue from the surface of all the tile immediately using a clean white cloth dampened with neutral detergent and water. Dried S-230 Adhesive cannot be removed.
9. Do not work on newly adhered tile except to roll tile. Use a kneeling board if necessary.
10. Continue Steps 4 through 9 until entire area is completed.
11. Do not allow traffic on tile for 24 hours after installation.
12. Flooring should not be exposed to rolling load traffic for at least 72 hours after installation to allow setting and drying of the adhesive.

• S-230 Adhesive is recommended for SAFETY ZONE in areas that may be exposed to frequent surface moisture and/or cooler temperatures.
• S-230 Adhesive may also be used to install the first 3 to 5 rows of SAFETY ZONE when used in areas that will be affected by surface moisture and/or cooler temperatures.
• Tiles are to be heated from the back only, never the face.
• Do not wash tile for at least four days after installation. This will allow the tile to become well seated in the adhesive and prevent excess moisture and cleaning agents from interfering with the adhesive bond.
• Products installed using the Tile-On System may have less resistance to indentation.We strongly recommend the use of Armstrong Floor Protectors.

• S-89 is not recommended over wood substrates.
