MIXING EQUIPMENT

• Drum stirrer

APPLICATION EQUIPMENT

• Air driven or electrical 2-component hot spray-equipment

Cementitious substrates must be structurally sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum tensile strength of 1.5 N/mm².

Substrates must be clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.

IMPORTANT

Do not dilute with solvent or water.

1. Pour all the container of Part C into the drum of Part B
2. Thoroughly stir the single drum of coloured resin using a drum stirrer to obtain a uniform colour.
3. Heat all three parts: Part A +67 °C : Part B + Part C +53°C.
4. Dose and mix with the spray equipment making sure constant air pressure is maintained.
5. Regularly check and control the accuracy of the mixing and dosage. The proportioning equipment must be capable of consistently supplying the correct pressure and heat.

IMPORTANT

Ventilation in confined spaces

Always ensure good ventilation when applying the Product in a confined space.

IMPORTANT

No application on unprimed or unlevelled substrates

Only apply the Product on primed or levelled concrete and screed surfaces.

IMPORTANT

No application on rising moisture

Do not apply on substrates with rising moisture.

IMPORTANT

No application on out-gassing substrates

Important: Do not apply on porous surfaces where significant moisture vapour transmission (out-gassing) will occur during application.

The Product is applied with specific temperatures for each component. If the application equipment only has a single fixed temperature setting use +70 °C and conduct application trials before undertaking the full application.

1. Apply the Product using air driven or electrical 2-component hot spray equipment.

Clean all tools and application equipment with Sika® Thinner C immediately after use. The application equipment must be cleaned and filled with Mesamoll. Hardened material can only be removed mechanically.
