the substrate. Allow the patch to dry completely before installing the flooring.
Scribing Felt is not recommended to be used under the entire installation.
Adhesive Open Times and Trowel Notchings
Adhesive Open Time Working Time
S-525 Approximately 20 minutes or more 24 hours
S-700 Approximately 30 minutes or more 18 hours
NOTE: All adhesives should be dry-to-touch before installing tile. The amount
of open time will vary according to job conditions, temperature, humidity, air
flow and type of substrate. All adhesives are applied with fine notching [1/32"
(0.8 mm) deep, 1/16" (1.6 mm) wide, 5/64" (2 mm) apart].
Procedure:
See Chapter V, Adhesives, Seam Treatments and Grout.
When using tile from two or more cartons, check to be sure all pattern and lot
numbers are the same to ensure proper color match. On larger installations,
open several cartons and mix them as they are installed to help blend any
slight shade differences from one carton to the next.
Procedure:
1. Line off entire area to be installed.
2. Apply the adhesive over the area, being careful not to cover 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 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. Clean adhesive from the surface of the tile following removal methods on
the adhesive label.
6. Tile should not be exposed to rolling load traffic for at least 72 hours after
installation to allow setting and drying of the adhesive.
NOTE: When installing tile be sure that all tile is firmly seated into the
adhesive. Rolling with a 100-lb. roller will achieve the same result and is
highly recommended.
