Hi guys, this is my 1st post although have been using the site for advice for a while - thanks!
My enquiry this time is that having attempted my 1st garden wall yesterday (I'm now half way through), I noticed that the cement is although hard to touch, is quite powdery and can be scratched away with relative ease. The mixture is supposed to be 1:5 (as per the insteructions on the bag for general purpose) but I'm wondering if this is a bit weak - I might also have been a bit lean with the cement anyway!
Can anyone advise whether this is going to be a problem and should I therefore restart, or should I continue with a stronger mix for the rest. Or perhaps am I just being a bit premature and will it harden with time? FYI, the wall is a semmi-retaining wall allowing me to build up the level of hardcore for a garage base, although shouldn't need to take a massvive amount of weight and is only 2 courses (blocks) high?
Sorry for the long-winded description...
Cheers,
Ross
