Concrete Construction Joint Filler Primer – 1 Litre

Concrete Construction Joint Filler Primer – 1 Litre

Bitumend CJF Primer is a specially formulated bitumen emulsion designed to work with micro trenching reinstatements. Used before applying Construction Joint Filler, this primer creates a superior bond between the filler material and the trench walls, dramatically improving performance and sealing.

Supplied in a 1-litre squeeze bottle, it’s easy to apply directly into the slot. Once settled, it forms a tacky surface that binds with the filler, helping waterproof and strengthen the repair.

Application Instructions:

• Ensure slot is clean and dry

• Shake well before use

• Apply a small amount directly into the slot

• Allow a few minutes for the primer to settle

• Add Construction Joint Filler and compact
