• Strong adhesion to concrete, brick, blockwork and masonry

• Non-corrosive and chloride-free, making it safe for reinforcement steel

• Minimizes cracking, delamination and rebound loss during guniting

• Improves the strength and durability of plaster

• Water-based, eco-friendly and simple to apply using brugh, roller or spray

• Ready-to-use formulation – no complex mixing required

• Bonding plaster or mortar to concrete, brickwork or blockwork

• New-to-old concrete applications (slabs, beams, columns, patch repairs)

• Dash coat or rendering prior to plaster or screed

• Primer for guniting, shotcrete, or tile fixing on concrete

• Bonding layer before cementitiour overlays

SURFACE PREPARATION

• Remove loose particles, laitance, dust oil, grease and curing agents.

• For old concrete, scrub, water-jet or mechanically roughen to expose a sound surface.

• Dampen the substrate to SSD (Saturated Surface Dry) condition – avoid standing water.


APPLICATION

• Stir Ultrabond Hack Free thoroughly before use.

• Apply neat as a primer or prepare a slurry by mixing 1 part Ultrabond Hack Free : 1 part fresh cement (by volume).

• Apply bonding coat using brush, roller or spray.

• Allow the coat to become tacky (approx. 5-15 min).

• Place plaster, mortar screed or new concrete while the coat remains tacky.

• For guniting/shotcrete, apply a thin primer layer to reduce rebound loss and improve adhesion.
