SikaBond DV

Concrete surfaces must be clean, sound, rough and free from oil, grease, cement laitance and loose particles, in a saturated surface-dry condition.

Mix SikaBond DV PK with water at 1:1, then combine with fresh cement and fine sand to a homogeneous, brushable slurry. Brush the slurry well onto the prepared surface.

In a suitable mixer, first mix cement and aggregate to a uniform consistency, then add the required quantity of diluted SikaBond DV PK and mix slowly for at least 2 minutes.

Apply the subsequent mortar while the bonding coat is still wet. Apply by steel trowel and finish with a wooden float. Never apply pure SikaBond DV PK or a DV-water mix directly as a bonding bridge; always add cement and sand.

Cure the fresh mortar properly, especially at high temperatures, using Sika Antisol WB or polyethylene sheet and wet hessian to prevent shrinkage. Clean tools with water immediately after use.
