IMPORTANT

Exposure to moist/wet heat

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

The amount of Hardener required depends on the substrate temperature:

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 or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.

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

~0.5–0.8 kg/m² (~0.5-0.8L/m²) depending on the system applied in 1–2 coats (total max. 0.8 kg/m² (~0.8L/m²))

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.

APPLICATION EQUIPMENT

• Short pile roller
• Squeegee

MIXING EQUIPMENT

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

PRIMER MIXING PROCEDURE

1. Mix Part A (resin) for ~30 seconds.
2. Add Part B (hardener) to Part A.
3. Mix continuously for 3 minutes, until a uniform mix is achieved.
4. To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
5. 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.

2-PART PIGMENTED

1. Mix Part A (resin) for ~30 seconds.
2. In a separate container, add 10 % of the final total weight of the pigment (Part C) and mix it with an equal amount of Part A, until you've achieved a homogenous premix. Refer to the mixing example below for further information.
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 at least 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.

1. Do not apply in the presence of foodstuffs.
2. 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(~0.8L/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.

1. 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.

1. 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 ineach area is applied from the same control batch numbers.

SEAL COAT FOR BROADCAST SURFACES

1. Pour the mixed Product onto the substrate. 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. Maintain a "wet edge" during application to achieve a seamless finish.
