How much material for capping wall All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

Hi. I'm looking to lay some coping stones (7 of them) on a new wall that someone built for me. The wall is 6m long and 29cm wide.

Is there a calculator to work out how many 25kg bags of cement and 25kg bags of sand I need?

Hi millsy5,
It depends on how thick you make the mortar layer but a 12.5kg bag of cement and 2 bags of building sand should be plenty. Do use plasticiser admixture to make mortar more workable and to extend its useable time.
