IMPORTANT

Exposure to moist or wet heat

Sikafloor® broadcast systems with a minimum thickness of ~3–4 mm, that use this product, can resist short-term moist or wet heat of up to +80 °C, if the exposure is only temporary (less than 1 hour). However, during exposure to moist or wet heat, do not also subject the Sikafloor® broadcast system to chemical and/or mechanical strain, as it may cause damage to the system.

Part A : Part C = 9 : 1 (by weight)

The amount of Part B required depends on the substrate temperature:

Note: For ease of handling, units may be split into smaller amounts. Make sure to follow the mixing ratios as described in the Application Information. Always weigh out each part before mixing it.

80 % r.h. max.

Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation on the surface of the applied product.

No rising moisture (ASTM D4263, polyethylene sheet)

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

Before overcoating the Product, allow:

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

Note: These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

APPLICATION EQUIPMENT

• Short pile roller

• Squeegee

MIXING EQUIPMENT

• Explosion-proof electric double paddle mixer (>700 W, 300 to 400 rpm)

2-PART PIGMENTED

1. Mix Part A (resin) for ~30 seconds.
2. Pigment is added at 10% by weight. In a separate container, add 2.5kg (2.5L) of the pigment (Part C) to 2.5kg of resin (Part A), and mix until you've achieved a homogenous premix.
3. Add this premix into the remaining Part A and mix for 3 minutes.
4. Add the required amount of Part B (refer to Mixing ratio in Application information) to Part A.
5. Mix for an additional minute, until a uniform mix is achieved.
6. To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
7. During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.

IMPORTANT

Protect from moisture

After application, protect the Product from damp, condensation and direct water contact for a minimum of 1 hour.

IMPORTANT

Ventilation in confined spaces

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

IMPORTANT

No application on rising moisture

Do not apply on substrates with rising moisture.

IMPORTANT

Ventilation for curing

For optimal curing, exchange the air at least seven times per hour. During application and curing, use a forced fresh air supply/exhausting of fumes with appropriate equipment (explosion-proof).

IMPORTANT

Remove foodstuff from application area

Reactive acrylic resins exhibit a characteristic odour during application and before achieving full cure. Once fully cured, they are taint free. All unpackaged goods must be removed from the area of the works during application.

• Do not apply in the presence of foodstuffs.
• Isolate any and all foodstuffs, whether packaged or not, from the flooring works during the application process and until the products are fully cured.

IMPORTANT

Excessive layer thickness may cause damage

If the coat thickness is exceeded (more than 0,8 kg/m²), the resin will tend to flake and yellow. If the coat thickness is too low, excessive monomer loss may occur, leading to insufficient hardness or lower water resistance.

• Make sure to follow the consumption as described in Application information.

IMPORTANT

Temporary heating

If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters. These produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.

• For heating, use only explosion-proof electric powered warm air blower systems.

IMPORTANT

Ensuring consistent colour matching

For consistent colour matching, make sure the Product in each area is applied from the same batch numbers.

IMPORTANT

Pin holes

If applied on porous substrates during rising temperatures pin holes may occur from rising air.

• Apply during falling temperatures.

SEAL COAT FOR BROADCAST SURFACES

1. Pour the mixed Product onto the substrate. Note: The consumption is specified in Application Information.
2. Apply the Product evenly over the surface with a squeegee.
3. Back roll the surface in two directions at right angles with a fleece roller. Note: Maintain a "wet edge" during application to achieve a seamless finish.

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