Directions for Use
IZOZENĀ® FLEXPRO DURACRETE can be used for cosmetic or structural repair of deteriorated concrete and mortar on exterior or interior, horizontal and vertical applications.
Steps:
Pre-Treatment
Ensure the substrate is clean, free of oil, grease, dust, and loose material.
Plug water leaks using IZOZENĀ® FLEXPRO FASTFIX-100.
Prepare the surface by water-jet washing or blast cleaning.
In hot climates, pre-dampen the surface (Saturated Surface Dry condition), but avoid standing water.
Bonding Agent
Apply a bonding agent such as IZOZENĀ® IZOBOND EP for better adhesion, especially on dense concrete or large areas.
Mixing
Mix a 25 kg bag with the recommended amount of cold water in a clean bucket.
Use an electric blender (max 500 rpm) with a spiral mixer.
Add powder slowly while mixing for at least 3 minutes until homogeneous and creamy.
Do not mix at higher speeds to avoid strength reduction.
Application
Apply while the bonding agent is still wet.
Use a spatula or trowel.
For thickness over 30 mm, apply in multiple layers.
Smooth with a wooden or synthetic float once setting begins.
For fine finishing, use IZOZENĀ® FLEXPRO DURACRETE F or IZOZENĀ® FLEXPRO STUCCO.
