Consumption
Coating system | Product | Consumption |
Primer | 1–2 × Sikafloor®-150 | 1–2 × 0.3–0.5 kg/m² |
Levelling mortar/Scratch coat | 1 pbw Sikafloor®-150 + 1 pbw quartz sand (0.1–0.3 mm) + 0.015 pbw Sika® Extender T | 1.7 kg/m² per mm of thickness |
Bonding agent | 1–2 × Sikafloor®-150 | 1–2 × 0.3–0.5 kg/m² |
Mortar screed (15–20 mm layer thickness ) / Repair mortar | 1 pbw Sikafloor®-150 + 10 pbw quartz sand | 2.2 kg/m² per mm of thickness |
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 largest grain size must be a maximum 1/3 of the finished layer thickness. Dependent on the grain shape and application temperatures, the aggregates and the most suitable mix should be selected. Other System configurations are provided in the corresponding product data sheets. Practical trials should be carried out for mortar mixes to assess suitable 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 product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

SUBSTRATE QUALITY
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.
SUBSTRATE PREPARATION
MECHANICAL SUBSTRATE PREPARATION
IMPORTANT
Surface defects due to voids in the substrate
Voids and blow holes in the substrate will weaken the surface and damage the covering Product if not repaired during the preparation process.
- Fully expose blow holes and voids during surface preparation to identify the required repairs.
- Remove weak cementitious substrates.
- Prepare cementitious substrates mechanically using abrasive blast cleaning, abrasive planing or scarifying equipment to remove cement laitance.
- Before applying thin layer resins, remove high spots by grinding.
- Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
- Use products from the Sikafloor®, Sikadur® and Sikagard® range of materials to level the surface or fill cracks, blow holes and voids.
Contact Sika® Technical Services for additional information on products for levelling and repairing defects.
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 substrate require pre-treating before full layer application. Use Sikadur® or Sikafloor® resins.
MIXING
Note: To increase the viscosity of the Product you can add Sika® Extender T.
2-PART MIXING PROCEDURE
- Mix Part A (resin) for ~30 seconds.
- Add Part B (hardener) to Part A.
- IMPORTANT Do not mix excessively. Mix Part A + B continuously for ~3 minutes until a uniform mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- 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
- Mix Part A (resin) for ~30 seconds.
- Add Part B (hardener) to Part A.
- While mixing Parts A + B, gradually add the required filler or aggregates.
- IMPORTANT Do not mix excessively. Mix for a further 2 minutes until a uniform mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- 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.
APPLICATION
IMPORTANT
Protect from moisture
After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.
IMPORTANT
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.
IMPORTANT
Pin holes
If the Product is applied on porous substrates during rising temperatures, pin holes may form from rising air.
- Apply the Product during falling temperatures.
IMPORTANT
Closing 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.
- Lightly grind the cured surface.
- Apply a scratch coat consisting of the Product mixed with ~3 % of Sika® Extender T.
STANDARD PRIMER APPLICATION
-
Pour the mixed Product onto the substrate.
Note: The consumption is specified in Application Information. - Apply the Product evenly over the surface with a short pile roller or a squeegee.
-
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. - If broadcasting is required, wait between 15 and 30 minutes, then broadcast the surface with quartz sand. Broadcast lightly at first, then to excess.
- IMPORTANT Confirm waiting or overcoating time 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.
