Application instructions

a) Preparatory work

Blow joints thoroughly with high-pressure air or clean with a brushing machine; cleaning and application must be separate tasks. Hot compressed-air lances can be used for artificial drying or pre-heating.

b) Application of the primer

The primer binds dust adhering to joint flanks and forms an adhesive layer that later fuses with the sealant. Apply COLZUMIX®-VPD by spraying or brushing; the primer must completely cover the flanks as a film. Use only as much primer as needed so no material pools in the bottom of the joint.

c) Pouring of the joint sealant

Before applying sealant, the primer must be touch-dry; joints must be dry and dust-free. Apply sealant directly after primer has dried. Avoid contaminating dried primer with dust or water — this may reduce bond between flanks and sealant.

Weather conditions

Prepared joints may only be sealed in dry weather and at a surface temperature above +5 °C.

Material consumption

COLZUMIX®-VPD: approx. 3 % of the sealant quantity required.
