IMPORTANT

Product damage due to mechanical and chemical strain at elevated temperatures

While the Product is exposed to temperatures up to +60 °C, simultaneous mechanical or chemical strain may cause damage to the Product.

1. Do not expose the Product to chemical or mechanical strain at elevated temperatures.

Beware of condensation. The substrate and uncured applied product must be at least +3 °C above the 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.

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

The following sand mixtures are suitable for layer thicknesses of 15–20 mm:

• 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

The maximum grain size must not exceed 1/3 of the finished layer thickness. Aggregates and the most suitable mix should be selected depending on the grain shape and application temperatures. For mortar mixes, practical trials should be carried out to assess the appropriate aggregate grain size distribution.

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

MIXING EQUIPMENT

• Electric double-paddle mixer (> 700 W, 300 rpm to 400 rpm)
   

APPLICATION EQUIPMENT

• Squeegee

• Fleece roller

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.

MECHANICAL SUBSTRATE PREPARATION
 

IMPORTANT
 

Surface defects due to voids in the substrate

1. If not repaired during preparation, voids and blow holes in the substrate will weaken the surface and damage the covering product.
2. Fully expose blow holes and voids during surface preparation to identify the required repairs.
3. Remove weak cementitious substrates.
4. To remove cement laitance, prepare cementitious substrates mechanically using abrasive blast cleaning, abrasive planing or scarifying equipment.
5. Where thin layer resins will be applied, high spots should be removed by proper grinding equipment.
6. Remove all dust and loose and friable material from the application surface with industrial vacuuming equipment.
7. Level the surface or fill cracks, blow holes and voids with products from the Sikafloor®, Sikadur® and Sikagard® range of materials.

For additional information on products for levelling and repairing defects, contact Sika® Technical Services.
 

SUBSTRATE PREPARATION OF NON-CEMENTITIOUS SUBSTRATES
 

For information on substrate preparation of non-cementitious substrates, contact Sika® Technical Services.
 

TREATMENT OF JOINTS AND CRACKS
 

Construction joints and existing static surface cracks in the substrate require pre-treating before full layer application. Use Sikadur® or Sikafloor® resins.

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

 
TWO-PART MIXING PROCEDURE
 

1. Mix Part A (resin) for ~30 seconds.
2. Add Part B (hardener) to Part A.
3. IMPORTANT Do not mix excessively. Mix Part A + B 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.

LEVELLING MORTAR AND RESIN SCREED MIXING PROCEDURE
 

1. Mix Part A (resin) for ~30 seconds.
2. Add Part B (hardener) to Part A.
3. While mixing Parts A + B, gradually add the required filler or aggregates.
4. IMPORTANT Do not mix excessively. Mix for a further 2 minutes until a uniform mix is achieved.
5. To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
6. 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 CONSIDERATIONS

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

Damaged finish due to heating with fossil fuel heaters: Fossil fuel heaters powered by gas, oil or paraffin produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish. For temporary heating, use only electrically powered warm air blower systems. Do not use gas, oil, paraffin or other fossil fuel heaters.
 

Pinholes caused by the application during rising temperature: If the Product is applied to porous substrates during rising temperature, pinholes may form from rising air. Apply the Product during falling temperatures.
 

Blistering caused by pin holes: If pin holes are present after the Product has cured, blistering may occur in the subsequent layer. Close any pin holes using the following steps.

1. Lightly grind the cured surface.
2. Apply a scratch coat consisting of the Product mixed with ~3 % of Sika® Extender T.
    

 
STANDARD PRIMER APPLICATION
 

1. Pour the mixed Product onto the substrate. Note For consumption, refer to Application Information.
2. Apply the Product evenly over the surface with a short pile roller or 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.
4. 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. IMPORTANT Confirm waiting time to overcoating is achieved before applying subsequent products. (Refer to the "waiting time to overcoating" section of Application Information) Once the product has hardened sufficiently, remove all loose sand with industrial vacuuming equipment.

 
SCRATCH COAT
 

1. Pour the mixed Product onto the substrate. Note For consumption, refer to Application Information.
2. Apply the Product evenly over the surface with a trowel or a squeegee.

 
BONDING AGENT
 

1. Pour the mixed Product onto the substrate. Note For consumption, refer to Application Information.
2. Apply the Product evenly over the surface with a brush, fleece roller or 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.
4. (Optional) If required, apply a second priming coat.

 
RESIN SCREED
 

Not suitable for contact with water: The Product is not suitable for contact with water unless sealed with seal coat.

1. Pour the mixed Product "wet on wet" onto the still tacky primer. Note For consumption, refer to 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.
