Removing the cement curtain
There are several techniques for removing cement curtains. Since not all tiles and grout are the same, not
all techniques are successful for all surfaces. Usually, the longer the cement curtain is on the tile, the more
difficult it is to remove. So, don’t wait too long or the problem may get worse!
The use of Betoff-Bio cement remover
Preparation: First, make sure that you take the necessary precautions. Cement curtains removers are
generally aggressive caustics. So, collect the waste and keep children away from it. The only non-
corrosive agent is Betoff-Bio.
Dilution: If the cement curtain is still fresh, you usually need to dilute the agent otherwise it may damage
the joints. The exact ratio varies by the different products, but we recommend that you always start mixing
both ingredients carefully. If the mixture doesn’t function well, you can always add a little amount of the
product to it. For old cement curtains, you can use a remover product in most cases (you must read the
instruction on the label).
Application of the agent: apply Betoff-Bio with a sponge or cloth. If desired, it can also be poured on the
Wait for the product to react: it depends on the severity of the problem; you have to give the product from
5 to 10 minutes.
Scrubbing: It’s best to start scrubbing the surface with a soft sponge. If that doesn’t function, try a scrub
brush. Use the abrasive sponge only when absolutely necessary, and it is advisable to use it only on
rough tiles. Smooth tiles can get scratched. Scrub vigorously with small circular movements; within short
time you should see the cement curtain fade away.
Rinse: when the removal is over, rinse the product with warm water. Do this twice to make sure the dirt
and fluid are disappeared. This is especially important in the bathroom, as otherwise product remnants will
stick to your feet.

Other methods of removing cement curtains from tiles

careful not to scrape it.

may damage joints (and even tiles!).
Dry Towels: It won’t be easy, but scrubbing heavily with a dry towel or old newspapers can also do well.
Window scraper: If nothing works, you can try using a window scraper. Scrape off the dirt piece by piece
without damaging the tiles.
How can I prevent the formation of cement curtains on the tiles?
To avoid dirtying the tiles, it may be necessary to cover them before grouting. Tiles that need to be joined
with cement mortar can easily be stained with it. If the tiles are stained with grout, you will notice a dull
layer of cement on them when they get dried.
Wipe the tiles
Immediately after the grout is dry, use a warm, wet sponge to wipe them completely. Do not scrub too
vigorously, otherwise doing so you may accidentally damage the joints. For this reason, do not start
cleaning them too early.
Sealing / coating
Another way to avoid cement curtain which is difficult get rid of you must seal properly the tiles before
grouting. Especially polished ceramic tiles have many invisible pores in which the cement can bind.
Impregnating these tiles before grouting will prevent serious problems.
