If using a concrete mixer, add 2 litres of clean water per bag of PROSTRENGTH® Extra Strength Concrete Mix (aka PRO-50) to the mixing vessel. Empty the PROSTRENGTH® Extra Strength Concrete Mix blend slowly into the water and mix thoroughly. If needing more workability, up to 0.5 litres of water may be added. Too much water ruins good concrete.

Or

if using a wheelbarrow, place Concrete Mix in the barrow, create a hollow and add 2 litres of water per bag and mix.  If needing more workability, up to 0.5 litres of water may be added. Too much water ruins good concrete.

Place the well mixed concrete in the formwork filling all corners, and compact. Level the concrete with a straight edge and finish the top surface with a wooden float or steel trowel. Keep the surface moist for 7 days to achieve maximum strength. Formwork may be removed after 24 hours. Don't walk on the concrete for at least 24 hours after placing.
