Hi,

Bit worried - just like to put my mind at rest...

I've stuck marmox board down to the floor before using Mapei Keraquick (on
their recommendation). It worked and it went hard as iron in a day. It was
however a complete ******* to work with because it grabbed like "No more
nails" and the bucket full is dead in 30 minutes so you have to be fast.

The next lot didn't need Keraquick[1] so I went over to Kerabond which is a
more normal powder mix cement adhesive with a long pot life.

How long might I expect it to take before it goes "hard as iron"?

After 24 hours it is set and the boards are firm, but it's not exactly rock
hard - overspilt bits can be crushed under fingernail.

Is this to be expected, not being an accelerated type like Keraquick? Might
I expect to see more hardening over the coming days?

----

Other question, on the same note - I've been using a 6mm square notched
trowell as the floor is pretty much dead flat. For future reference, might
I be better with a slightly thicker bed or perhaps one of the round-notched
trowells - or am I good to stick with the 6mm?

Ta as always

[1] Recommended as the first floor had some damp issues but was otherwise
stable. Current floor has been fully sorted...

yes. In my experience with Ardurit. 48 hours or so.

Cool - though it was likely to be the case.

Hi,

Try Keraflex, it's nice to work with, about 3-4 hour pot life and
30-40 mins open time, but sets up nicely in a day.

6mm is a wall trowel. You should be getting a solid bed on floor
tiles, which a 6mm square notch won't give you.

This is a good floor trowel:

I've only done a couple of small areas so far.

I'll get one of those pronto

Cheers

So many choices!

OK I'll take that as a recommendation when I run out of my current batch.
