Was grouting some new tiles, using the combined waterproof adhesive/grout,
and got called away before finishing off. The actual grouting is fine -
but a lot of residue on the tile faces, now rock hard. Tiles are ceramic
and matt finish. Any tips on the easiest way to remove the residue?

No-one? I can scrape it off with a chisel without damage to the tile. Was
hoping someone knew a quicker way.

Residue as in a thin film or ridges of set grout? For the former just
use the shower and wipe down the tiles after every use it'll
eventually go. Even the ridges become slighly less attached after "a
while".

Naw, not with a cement based waterproof grout. Spray with a mild
acid, citric or calgon or kettle descaler or WHY. Might be able to
make a paste with citric spread on scrape off hopefully with the
grout or just work it in/around with an old tooth brush. Any scraper
needs to soft and not metalic.

I don't think it's a mortar based adhesive. Not the sort you'd use for
tiling outdoors. More water resistant than waterproof. Fine for an
occasional use shower room walls.

There is stuff called HG cement grout film remover 1L - "the grout remover
for all types of tiles and flagstones"

https://www.amazon.co.uk/HG-cement-g...3910865&sr=8-7

At £8.59 a litre.

There's probably a PDF somewhere giving its precise chemical composition
and whether it contains anything over and above the standard cheaper
recommendations which are of acid of various types/strengths

The packaging will tell you. Or just keep it wet for an hour or two
ordinary grout/adhesive will soften, waterproof won't even notice.

Thin film may come off with a non-scratch scourer.

I find a box cutter about the right combination of flexible and blade
width for scraping off bits of set grout. The waterproof stuff once
fully cured is only going to come off by physical removal.

If you have a steady hand a stanley knife with the blade in paper
scraping configuration will give you an even wider scraper edge.

Well spotted. So its main constituents are

Phosphoric acid - which is found in soft drinks and gives them their
tangy flavour

Oxalic acid which is found in rhubarb leaves and the green bits of
potatoes

ethoxylated isofridecanol which is found in everything from washing
and cleaning products, to air care products, greases polishes and waxes.

So that rather than fork out £8.59 for a litre of HG cement grout film
remover


https://www.amazon.co.uk/HG-cement-g...3910865&sr=8-7


just boil up some rhubarb leaves in a saucepan of supermarket
lemonade and sling in a bit of washing powder and floor polish.

The clue to the effectiveness may be in the word "film" and it may be
effective on the haze that is left after a brief wipe-off rather than
removing bulk material.

Those green plastic pot scourers seem to do it OK. Without scratching the
surface. A wheel made of that to fit a power tool would be great.

Green pot scourers (ie the scouring bit) are normally "scratch" and
some can be quite agressive. The white ones are "non-scratch". Might
not be quite so an issue on matt compared to a smooth or gloss
surface.

Ooo, they look interesting, thanks. Quite a selection of different
types and grades to choose from as well. Wonder if they'd be better
used with a random oribtal sander rather than drill?

Must admit to being a bit cagey using a mains powered tool in
combination with the required lubricating/debris removal water.

Ebay has plenty refills and cheap - but from China. I can see this being
very useful for lots of other things if it does what it says on the tin.

I have a plastic window scraper that takes a standard stanley
blade. Useful for going over a window, wetted with water and
some washing up liquid, after external painting, to remove
any miscreant blobs and small splashes of paint.

Harpic ?. Contains dilute HCL and is sticky enough to
adhere to the tiles rather than running off too quickly.

Earlier this week I re-enameled our 50 year old bath. I managed to get a
line of this 2 part paint above the masking tape.
A window scraper removed the paint without scratching the tiles.
Note: The tile are not completely flat. It's like they had paint dripped on
them & were then glazed over the top so that the whole surface undulates.

If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such
time as the State can shield the people from the political, economic
and/or military consequences of the lie. It thus becomes vitally
important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.

I've over boarded two ceilings this year and still have one to do. I
invested in a plasterboard hoist after remembering the hassle I had when
I was younger

https://tinyurl.com/y5odd9cc

My original ceilings were at 9 foot.

The other cheap accessory that was a god-send was a plasterboard handle
which made one man shifting of 2.4m x 1.2m plasterboard sheets a doddle
(as long as they didn't have to go up-stairs which has a 90 degree
bend). Luckily the only room upstairs that required a new ceiling was a
small box room requiring only two plasterboard sheets.

https://tinyurl.com/y2767vle

Only one handle is required for a one man to lift a sheet of
plasterboard - just get it in the middle of the longest edge.
