Solvent free epoxy

24 months from date of production

The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Always refer to packaging.

~100 %

IMPORTANT

No simultaneous mechanical and chemical strain

While the product is exposed to temperatures up to +60 °C, do not also subject it to chemical and/or mechanical strain, as it may cause damage to the product.

80 % r.h. max

Beware of condensation. The substrate and uncured applied floor material 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.

The following sand mixtures are indicative mix design quantities that must be confirmed by pre-trials. Grain size distribution for layer thicknesses of 15–20 mm , parts by weight (pbw):

25 pbw quartz sand 0,1–0,5 mm

25 pbw quartz sand 0,4–0,7 mm

25 pbw quartz sand 0,7–1,2 mm

25 pbw quartz sand 2–4 mm

Note: The largest grain size may not exceed 1/3 of the finished layer thickness. Dependent on the grain shape and application temperatures, the sand and the most suitable mix must be selected and confirmed by pre-trials.

Unsuitable mixing equipment

Do not use free fall mixers.

Mixing equipment

Electric double paddle mixer (300 to 400 rpm)

Note: To change the viscosity of the Product you can add Sika® Extender T.

Mixing procedure

1. Mix Part A (resin) until the coloured pigment is dispersed and a uniform colour is achieved.
2. Add Part B (hardener) to Part A.
3. Mix Part A + B continuously for ~3 minutes until a uniformly coloured 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.

IMPORTANT

Protect from moisture

After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.

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 electric powered warm air blower systems.

Standard primer application

Equipment:

• Fleece roller
• Squeegee

1. Pour the mixed Product onto the substrate. The consumption is specified in Application Information.
2. Apply the Product with one of the tools specified in Equipment.
3. Back roll the surface in two directions at right angles with a fleece roller. A seamless finish can be achieved if a "wet" edge is maintained during application.

Levelling Mortar

Equipment:

• Squeegee

1. Pour the mixed Product onto the substrate. The consumption is specified in Application Information.
2. Apply the Product with one of the tools specified in Equipment.

Intermediate layer

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 serrated trowel.
3. Back roll the surface in two directions at right angles with a spike roller.
4. (Optional) If broadcasting is required, wait between 15 and 30 minutes, then broadcast the surface with quartz sand. Broadcast lightly at first, then to excess.
5. (Optional) Once the product has hardened sufficiently, remove all loose sand with industrial vacuuming equipment. IMPORTANT: Confirm waiting /overcoating time is achieved before applying subsequent products. (Refer to waiting / overcoating times in Application Information)

Bonding bridge

Equipment:

• Fleece roller
• Squeegee

1. Apply the Product with one of the tools specified in Equipment.
2. Pour the mixed Product onto the substrate. The consumption is specified in Application Information.
3. Back roll the surface in two directions at right angles with a fleece roller. A seamless finish can be achieved if a "wet" edge is maintained during application.
4. (Optional) If required, apply a second priming coat.

Resin screed

IMPORTANT

For applications in layers more than 30 mm thick, always use a welded steel wire mesh (6 mm to 8 mm diameter and square grid centres of approximately 100 mm × 100 mm), placed at the centre of the screed.

1. Pour the mixed Product "wet on wet" onto the still tacky primer. The consumption is specified in Application Information.
2. Spread and compact the Product with a trowel to the required thickness between screed rails / battens, if installed.
3. Level the screed surface with a levelling beam spanning onto the screed rails / battens.
4. Finish the surface to the required surface texture with trowels or walk-behind power floats.

Resin patch repair mortar

1. Pour the mixed Product "wet on wet" onto the still tacky primer.
2. Apply the Product with a trowel to the required thickness.
3. Compact the applied product with a trowel.
4. Smoothen the surface with a trowel. IMPORTANT: Confirm waiting /overcoating time is achieved before applying subsequent products. (Refer to waiting / overcoating times in Application Information)

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