Application instructions

a) Preparatory work

Blow asphalt and concrete joints 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 on concrete and asphalt and forms an adhesive layer that later fuses with the sealant. Apply COLZUMIX®-Haftgrund to joint flanks by spraying or brushing; the flanks must be completely covered as a film. Apply about a 1 cm strip on the road pavement on both sides of the joint. Use only as much primer as needed so no material pools in the bottom of the joint.

c) Filling of the joints

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 of at least 0 °C.

Material consumption

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

Cleaning agents

Equipment: petrol and commercial solvents
Skin contact: hand cleansing paste

Storage

Store only in well-ventilated areas; protect from direct sunlight. Shelf life at least 24 months when stored cool and dry. Observe the safety data sheet.
