How do you make cement more sticky? I'm trying to fix down a loose
paving stone (part of some steps). Have used cement:sand at 1:6 as
recommended on packet but it keeps coming loose again.

1:6 is actually a very weak mix. Nearer 1:3 would be better. Paint the
surfaces with a dilute solution of PVA adhesive and leave to dry. Use PVA
in the gauging water too.


I'd use Gripfil
