Tile, stone and grout in a patio, around
a pool or a decorative walkway should be inspected and
maintained yearly.
Many exterior tiles are vitreous (non-porous), and resist the freeze/ thaw
cycles of the outside elements which can damage the tiles. In warmer regions,
soft bodied non-vitreous paver tiles are often used. These tiles are porous
and will not hold up well in wet or cold climates. These unglazed tiles even
in light to moderate rainfall should be sealed, as well as the tile grout, with an appropriate sealer to help prevent moisture penetration.
The original installation should have
included strengthening additives to the thinset and a
quality grout. If the grout appears damaged or is crumbling
away in certain areas, there could be problems with the
concrete base substrate or an improper grout mix may
have been used.
Exterior grout most of the time will be
a sanded grout mixed with water and sometimes a latex
additive for flexibility and moisture resistance. Always
follow the grout manufactures mixing recommendations
for the application. It cannot be stressed enough that
the proper ratios of dry mix to water or latex be followed
as an improper mix will weaken the strength, adhesion
and color consistency of the grout.
Grout removal and repair on patio tile
and stone involves the same processes used for interior
tile grout repair. If you are looking to change the color
of the grout, the grout colorant we sell on our products
page can help you achieve your goal. If you have dislodged
grout and need to repair certain areas, start with a
Grout Getter, model G13T, and remove the damaged grout.
Next, purchase some exterior grout of the color you need
and follow the grout manufacturer’s guidelines
for mixing and installing.
Once your grout repair or replacement
is complete on your patio tile, remember, a sealer is
worth its’ weight in gold! The sealers we sell
preserve your tile and grout from the harsh elements
of the outdoors. Stains, minerals, mold, mildew and fluctuating
temperatures can all have damaging affects on your patio
tiles, so seal and protect- it’s well worth it! |
