Hi, this is the first time I've posted here. My husband and I
will be tiling our bathroom and were wondering which type of
grout sealer to use, the 1 yr or 20 yr. (both penetrating
sealers). At first we thought that the 20 yr with teflon was
surely better, but when i read the container, i saw that you are
not supposed to use cleaners with ammonia, acid or bleach on this
sealer, which pretty much covers anything i would use to clean a
bathroom floor. Any advice or comments as to the pros and cons
of these sealers? We will be using engineered tile if that
makes a difference.
i've only ever used the shorter-duration old-fashioned kind. it works
fine. sealer is the most important part of the job i feel, esp on a
floor. you can apply it with a small paintbrush after the grout dries
thoroughly. i am anal retentive and always do 2 coats.
Why would you go through the effort of using a one year
sealer, when you can use a 20 year? So you can use
harsh cleaners such as bleach, which are bad for the grout
anyway? There are many, many good cleaners that don't
contain harsh chemicals damaging to grout.
The prime reason people have so many problems with their
shower or tub grout falling apart is that it's been cleaned
hundreds of times with bleach or acid/type products and the
grout can't take it anymore.
Get the more expensive sealer and put down one heavy coat
with an applicator bottle. Assuming you are using a
polymer modified grout, one coat will be enough and will
make any liquid bead on it. A second coat is not needed
on polymer grout, and will be a pain to apply because it
will just bead onto the first coat. The object is to apply
only enough so liquid no longer soaks into the grout,
which, as I said, is one heavy coat over polymer modified
grout, allowed to dry overnight.
I use HomeyDepot's more expensive water-based sealer.
It's the dark (brown?) one that's $15 a pint. I use the
round applicator bottle with the brush on top. Pull the
brush backwards and deposit the sealer into the joint.
It will dry quickly, but needs 24 hours to cure.
And do some research and find some quality cleaners
that won't hurt your grout.
Wait at least 3 days after grouting before sealing grout.
What type of cleaners should you use? I don't want to have to
order a specific brand from the grout sealer maker, and the lady
at home depot was no help - besides warm water she didn't know
what cleaner was ok to use. I googled it and just found grout
cleaners (like stain removers) and one specific tile-lab brand
I like the idea of putting down one heavy coat, thanks for the
suggestion. I am so used to painting and putting down multiple
thin coats, i would have probably done that.
Spic and Span, soft scrub, simple green etc.
Just read the labels and use any detergent that
doesn't have bleach or acids. I never heard
the "don't use ammonia" thing.
Any properly diluted, safe detergent should
easily clean a sealed grout.
As I said, what destroys grout is when people
insist on using straight bleach, or straight 'tile-ex",
or strong cleaners containing acids on a regular
If you use diluted, mild detergents you should
never have a problem.
