How to secure loose block paved steps

[dazzystar]

Hi All,

We have steps leading out from our back door which are made from block paving. A couple of these blocks have come loose and I'm looking for advice on how to secure them. Strangely, when I look under the loose blocks there appears to be no cement stuck to them.

Can anyone offer some advice please?

Cheers
Daz

Thanks very much. Never thought of that. Does it bond to both the block surface and the sand / cement mix underneath?

As long as the mortar is not loose and you brush it first

Thanks. I've ordered a couple of tubes and will let you know how it goes!
