Epoxy resin, quartz aggregates and specific admixtures

12 months from date of production if stored properly

Store in a cool, dry area in original sealed packaging and at temperatures between +5 °C and +35 °C. Protect from direct sunlight, heat and moisture.

~1.90 kg/l (Mixed at +25°C)

Permanent exposure to dry heat: max. +50°C

Note: No simultaneous chemical and mechanical exposure.

Resistant to many chemicals. Please contact Sika's Technical Department for chemical resistance table.

+10°C min. / +35°C max.

+10°C min. / +35°C max.

< 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).

~60 min at temperature of +25°C

~30 min at temperature of +40°C

Note: The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife.

Coverage rates are dependent on the specified tile or pavers dimensions.

As a general guide, the approximate consumption can be calculated by volume, where ~1,9 kg/m²/mm of material is required for solid bed application.

Consumption of tile grout can be calculated through the following formula: ((L1+ L2) x W x T x D ) / (L1 x L2) , where:
▪ L1 = Tile length (mm)
▪ L2 = Tile width (mm)
▪ W = Joint width (mm)
▪ T = Tile thickness (mm)
▪ D = Density of tile grout (kg/l)

Note: Final result will be in kg/m².
Note: All figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.

Ensure all laitance and contaminants such as oil, grease and coating systems are removed by either mechanical wire brushing or grit blasting. The surface should be dry and any dust should be removed by an industrial vacuum. The surface should contain no more than 4 % moisture and any major repairs in the form of damaged arrisses, cracks and honeycombing should be repaired with the appropriate Sika® repair system. Where minor blemishes like blowholes exist, these can be filled out simultaneously with the bedding adhesive when it is applied.

Depending on the contaminants to be removed, perform adequate preparation techniques, such as jet washing or blastcleaning, in order to remove all traces of any materials that could reduce the product's adhesion on the substrate.
Joints should be cleaned at least to two thirds of the depth of the tile.

SikaCeram® RSG 705 is reactive product of a heavy consistency. This means that it sets through a chemical reaction between the components. It is therefore crucial to ensure that these components are thoroughly mechanically mixed with the correct mixing ratio.

Using a slow speed electric drill with a paddle attachment, pour the reactor (Part B) into the base tin (Part A) and mix for approximately 2 minutes or until a uniform consistency and colour is obtained. Pour the mixed resin into a forced action mixer and slowly add the filler (Part C) mixing until a lump free, uniform consistency is achieved. The finished mix should have a very creamy consistency, is uniformly coloured and it is easy to apply and spread.

In most applications, the full contents of each component pack should be mixed together. However, where necessary, up to 2kg of the Part C
may be omitted to facilitate application at low temperatures, to improve the application properties on floors or to aid application into narrow joints.

To the prepared surface apply a solid bed of adhesive to a minimum thickness of 3 mm. Ensure that the size of the working area can be tiled within the pot life of the SikaCeram® RSG 705. On vertical applications, the adhesive must be applied with a notched trowel to leave a ribbed bedding.

Curing

Good curing is essential for resin based materials to ensure specified performance. A minimum temperature of 10°C should be maintained during the curing period by the use of additional heating if necessary. Installations using SikaCeram® RSG 705 systems can be opened to foot traffic after approximately 24 hours at 20°C. Complete cure is achieved after 72 hours at 20°C.

Tiling

Tiles and pavers should be pressed firmly into place with a twisting motion until properly aligned and bedded. On vertical applications, tiling should begin from the bottom upwards. Ensure that at least 75% of the tile back is in contact with the adhesive. A minimum width of 2 mm must be left around tiles for grouting.

Grouting

The grouting operation can be carried out simultaneously with the application of the bedding mortar or after the bedding mortar has set. When
proceeding with one continuous operation, apply extra thickness in the bed to allow for material to ooze through the gaps once tiles are pressed onto the adhesive. The grout is then trimmed off and grouted joints are finished with a spatula or palette knife. Where grouting is to be carried out after the bed has set and tiles are permanently fixed in place apply the epoxy grout to the joints by plastic spatula and finish off. Following the grouting operation use a fibrous pad or wet soft cloth to clean off the excess material. This should take place within 15 minutes and care should be exercised not to use excess water or allow water to come into contact with the wet grout. Surplus material must be removed from the face of the tiles before it sets.

Clean all tools and application equipment with water immediately after use.
Hardened and/or cured material can only be removed mechanically.
