What needs to be sealed? Most grout and all stone tile is
porous prior to applying a sealer or enhancing sealer. Especially
in wet or high traffic areas, it is imperative that all grouts and all
natural stones get sealed to prevent stains and mold growth.
Man made tiles like (porcelains, ceramics, glass, and metals),
epoxy grouts, and some grouts with liquid additives are the
exception. They are non-porous and will not absorb water or
stain. Tile can be sealed at anytime, but grout has to be fully
cured which usually takes 48-72 hours. Note that slate and
quartzite tiles should also be sealed at least 1 hr prior to grouting.
A penetrating sealer will leave stone tile and grout looking as it
naturally does with no-sheen. An enhancer seals the stone but
also deepens the color of the tile leaving it darker than before and
giving it an almost wet look. You can test what a stone tile will
appear like after being enhanced by wetting it down with water.
If enhancer is applied after grouting it will also darken the grout
color. Enhancer can be applied prior to grouting in order to
preserve the color.
Cleaners: A tile, stone, and grout cleaner will prolong the life of
your sealer. See any local tile store or home improvement center
for tile, stone, and grout cleaners.
Sealers and Enhancing Sealers are very important during
and after tile installation. Sealing tile and grout is simple, but
sometimes gets overlooked on tile projects. Sealers and
enhancer sealers repel water and prevent stains on stone tile and
1) For new installations, sealers can be applied 48 hrs after
grouting or at least 1 hr prior to grouting stone tile. 2) Surface
must be clean and dry. 3) Apply 1 to 2 coats using a sponge,
brush, paint pad, or sprayer. One coat should be sufficient for
most dense surfaces. 4) Sealer should not be allowed to pool or
puddle on surface for more than 5 to 10 minutes. Using
absorbent paper or cotton towels, remove and polish dry any
sealer that doesn't penetrate into the stone or grout within 5-10
minutes of application. 5) Allow a minimum of 30 minutes drying
time between coats. 6) Ready for surface traffic in 2 hours.
Keep area dry for at least 12 hrs. Achieves full water repellency
after 24 hours.
Maintenence: Sealers can last from 6 months to 12 years
depending on the use of the area. Most sealers recommend
using a cleaner specifically for tile and grout to prolong the life of
the sealer. You can test to see if your sealer is still working by
dripping a small amount of water on the stone tile or grout. If it
beads up like a freshly waxed car your sealer is still working.
You should test your sealer annually in high traffic areas or
