İzo Epoksi 5008 Surface Preparation, Application, and Rules Guide

Surface Preparation

• Ensure the surface is dry, sound, and has sufficient compressive strength ($\min. 25\text{ N/mm}^2$).

• The pull-off adhesion strength of the surface must be at least $1.5\text{ N/mm}^2$.

• The surface must be clean and free from residues that would prevent adhesion, such as dust, dirt, oil, coatings, and surface curing materials.

• Concrete surfaces should be abraded using abrasive equipment suitable for surface characteristics to obtain a pored surface, removing the cement slurry to reach the aggregate.

• The concrete surface to be applied should be cleaned with the help of a water jet.

• The moisture content in the surface should not exceed %4 by weight, and there should be no rising moisture from the surface (performing a PE sheet test is recommended for control).

• Ensure that the floor temperature remains constant between min. $+10\text{ }^\circ\text{C}$ and max. $+30\text{ }^\circ\text{C}$ and is at least $+3\text{ }^\circ\text{C}$ above the dew point.

• Before application, check the suitability of conditions for surface moisture, relative humidity, temperature, and dew point.

Application

• İZO EPOKSI 5008 comes in ready sets according to the mixing ratio, ensuring the product to be mixed is between $+15\text{ }^\circ\text{C}$ and $+25\text{ }^\circ\text{C}$.

• Component A should be stirred in its own container before Component B is added.

• The entire Component B must be added to Component A, ensuring no material is left in Component B’s container.

• An electric mixer at low speed (300-400 rpm) should be used for mixing, stirring continuously for approximately 3 minutes until a homogeneous mixture is achieved.

• After letting the mixture rest, it should be remixed for 2 minutes, avoiding excessive mixing to prevent air entrapment.

• Depending on the surface, silica sand ($0.1-0.3\text{ mm}$) can be added at a ratio of 1:0.50 to 1:2 by weight to thicken the material for priming.

• The ambient temperature during application must be in the $+15\text{ }^\circ\text{C}$ to $+25\text{ }^\circ\text{C}$ range.

• High temperatures can decrease drying/curing times, viscosity, and associated consumption, while low temperatures can increase these durations.

• It can be applied by spreading with a brush, rollable application, or a flat trowel onto the surface.

• Ensure that a continuous and non-porous layer covers the surface.

• If the primer is to be covered with an epoxy or polyurethane-based material, silica sand with a fraction of $0.3\text{ mm}$ to $1.0\text{ mm}$ should be broadcast onto the primer while it is still wet at a consumption rate of $1\text{ kg/m}^2$.

• The waiting time for applying subsequent layers should not exceed 48 hours; if exceeded, abrading and applying a fresh primer or scratch coat is recommended.

Rules

• Avoid application at temperatures below $-5\text{ }^\circ\text{C}$ and above $+35\text{ }^\circ\text{C}$.

• Avoid application on frozen surfaces, surfaces with a risk of freezing within 24 hours, or in areas directly exposed to sunlight and wind.

• Do not add external water to the mixture.

• The powder component must always be added to the liquid component.

• During application, the wet film thickness for a single layer must not exceed $2\text{ mm}$.
