Features and benefits:

• Impermeable to liquid water.
• Improves wear resistance and resistance to freeze and thaw cycling.
• Increases compressive and flexural strength.
• Reduces compressive modulus.
• Reduces shrinkage, water demand and aids early drying.
• Strong adhesion.
• Provides protection to steel reinforcement.

Application:

• Prepare concrete in accordance with instructions.
• Prime exposed steel and prepared concrete with a slurry of Ronafix SBRand cement 1:1 by volume.
• Apply mortar to wet or tacky primer.
• Build multiple layers, as required; prime between layers.
