Use and Care Manual
1. Be sure to clean the surface you are installing tile on to. Any dirt
or debris can affect the adhesive’s ability to adhere your Subway
Tiles to the substrate.
2. Measure  and  mark  the
center  points  of  both  the
vertical  and  horizontal
dimensions of your wall.
3. Snap  a  chalk  line  between
these  points  to  create  your
centerlines.  Check  the
intersection  of  the  chalk
lines with a carpenter’s square to ensure that it is fully square.
4. Layout  your  tiles  without  adhesive  from  your  intersection  point
towards  the end of the wall.  If  your layout results  in  pieces that
are too small to cut along the edges, then adjust your centerlines
accordingly and resnap chalk lines.
Mixing Thin-set 
1. Be sure to follow mixing directions on bag on all points. You need 
allow  the  thin-set  to  sit  between  mixings  –  as  the  instructions
describe - because it is during that time that the cement slakes. If
you do not do this, the bonds will be weak and the thin-set will not reach maximum adhesive performance.
2. DO NOT ADD EXTRA WATER ONCE MIXED. This will weaken the adhesive strength of the MAPEI Adesilex
P10 – specifically formulated for glass tile applications. If the thin-set is drying up, then remixing will return some
of its fluidness.
3. Placing a damp towel over the bucket used to mix the thin-set will extend its “pot life”.
Applying Thin-set
1. Using the flat side of the trowel spread the adhesive onto the working area.
2. Only apply as much area as you can tile in the next 15 to 20 minutes (The open time for Adesilex P10 is 25 to 35
minutes). If you are not able to tile over thin-set that you have applied within this period, then you must scrape the
adhesive off the surface and reapply.
3. Comb the notched side of the trowel across the thin-set. This ensures that an even and proper amount of thin-set is
applied to your substrate.
4. Take the flat side of the  trowel and knock down the ridges of thin-set so that the surface is covered evenly with
adhesive.
5. This ensures that shadows from the ridges are not seen through the tile after installation.
