Consumption| System | Product Consumption | | Primer | 1–2 × Sikafloor®-150 1–2 × 0.3–0.5 kg/m² | | Leveling mortar | 1 part Sikafloor®-150 + 1 part quartz sand (0.1–0.3 mm (0.0039–0.0118 in)) + 0.015 parts Sika® Extender T 1.7 kg/m²/mm | | Connecting bridge | 1–2 × Sikafloor®-150 1–2 × 0.3–0.5 kg/m² | | Epoxy screed (layer thickness 15–20 mm (0.591–0.787 in)) / Repair mortar | 1 part Sikafloor®-150 + 10 parts quartz sand 2.2 kg/m²/mm |
The following sand mixtures are suitable for layer thicknesses of 15–20 mm (0.591–0.787 in): - 25 parts quartz sand 0.1–0.5 mm (0.0039–0.0197 in)
- 25 parts quartz sand 0.4–0.7 mm (0.0157–0.0276 in)
- 25 parts quartz sand 0.7–1.2 mm (0.0276–0.0472 in)
- 25 parts quartz sand 2–4 mm (0.0787–0.157 in)
The maximum grain size must not exceed 1/3 of the final thickness of the layer. Aggregates and the most optimal mixture will be chosen depending on the shape of the granules and the temperature at which the application is made. Other system configurations are provided in the product data sheets. It is recommended that preliminary tests be carried out on mortar mixes to assess the optimal distribution of aggregate grain size. Note: These values are theoretical and do not take into account additional consumption due to surface porosity, surface profile, unevenness or losses, etc. To accurately calculate substrate-specific consumption with the proposed application equipment, apply the product to a test surface. EQUIPMENTMIXING EQUIPMENT - Electric mixer with double paddles (> 700 W, 300 - 400 rpm)
APPLICATION EQUIPMENT - Short hair stencil roller
- Rubber scraper
SUPPORT QUALITYThe cement support layer (concrete/screed) must be solid and have sufficient compressive strength (minimum 25 N/mm 2 (3626 psi) ), with a minimum pull-out strength of 1.5 N/mm 2 (218 psi) . The support must be clean and free of contamination, such as: impurities, residues, oils, fats, coatings or previous surface treatments, friable materials, etc. PREPARATION OF THE SUPPORTMECHANICAL PREPARATION OF THE SUBSTRATE IMPORTANT Surface defects due to voids in the substrate Cavities and surface defects in the substrate will weaken the surface and damage the coating product if not repaired during the preparation process. - Fully expose cavities and surface defects during surface preparation to identify necessary repairs.
- Weak cementitious support layers must be removed.
- In order to remove milk from the cement, the concrete supports must be prepared by techniques and with appropriate mechanical equipment, such as sandblasting with metal alice, scarification or milling.
- When applying thin resin coatings, use mechanical sanding to remove burrs and bumps.
- Use industrial vacuum equipment to remove dust and friable material from the surface before applying the Product.
- Use products from the Sikafloor®, Sikadur® and Sikagard® range of materials for leveling the surface or filling cracks and holes/gaps.
- Contact Sika Technical Department for further information on leveling and defect repair products.
PREPARATION OF OTHER TYPES OF SUPPORT LAYERS Contact the Sika technical department for further information on the preparation of other types of support. TREATMENT OF JOINTS AND CRACKS Constructive joints and surface static cracks existing in the support layer require prior treatment by local filling with material and leveling. In this way, the surface is sealed against material loss before the floor finish is applied. Use Sikadur® or Sikafloor® resins. shuffleNote: To increase the viscosity of the Product, Sika® Extender T can be added to the mixture. PRIMER MIXING PROCEDURE - Mix Component A (resin) for 30 seconds.
- Add Component B (the hardener) over Component A.
- IMPORTANT: Do not over mix. Mix Components A + B continuously for 3 minutes until a uniform mixture is obtained.
- To make sure they are mixed evenly, pour the contents into another container and mix until a homogeneous mixture is obtained.
- In the final mixing phase, scrape the sides and bottom of the container with a straight/flat-edged spatula or trowel at least once to ensure thorough mixing.
LEVELING MORTAR / EPOXY Screed MIXING PROCEDURE - Mix Component A (resin) for about 30 seconds.
- Add Component B (the hardener) over Component A.
- While mixing Components A + B, gradually add the quartz sand
- IMPORTANT: Do not over mix. Mix Components A + B continuously for 2 minutes until a uniform mixture is obtained.
- To make sure they are mixed evenly, pour the contents into another container and mix until a homogeneous mixture is obtained.
- In the final mixing phase, scrape the sides and bottom of the container with a straight/flat-edged spatula or trowel at least once to ensure thorough mixing.
APPLICATIONIMPORTANT Protect from moisture After application, the Product must be protected from moisture, condensation and direct contact with water for a period of at least 24 hours. IMPORTANT Damage to the finish due to heating with fossil fuel appliances Fossil fuel heat sources powered by gas, oil or paraffin produce large amounts of carbon dioxide and water vapor, which can adversely affect the surface finish. - For temporary heating, use only electrical equipment (air heaters, etc.). Do not use gas, oil, paraffin or other fossil fuel heat sources.
IMPORTANT Pinpoint defects If the Product is applied to porous substrates at elevated ambient temperatures, "needle-prick" defects may result. - Apply the Product at decreasing ambient temperatures.
IMPORTANT Pinpoint defect repair Applying the next layer to a primed substrate that has "pinprick" type defects can lead to similar defects in it. Repair the defects by following these steps: - Lightly sand the primed surface (completely dry).
- Apply a leveling and pore closing layer consisting of the mixed Product and an addition of ~3% Sika® Extender T.
STANDARD PRIMER APPLICATION - Pour the mixed Product onto the backing layer. Note: Consumption is specified in the "Application Information" section.
- Apply the Product evenly to the surface using a roller or rubber squeegee.
- Uniformize by rolling with the short hair stencil in two perpendicular directions, in a cross. Note: To achieve a seamless finish, keep the "wet edge" during application.
- If quartz sand spreading is required, wait 15 to 30 minutes, then spread quartz sand over the surface, first lightly dispersed, then to excess.
- IMPORTANT Make sure that the waiting/recoating times are respected before applying the following products (see "Waiting/recoating time" section). Once the product has cured sufficiently, remove all unincorporated sand using industrial vacuum equipment.
LEVELING MORTAR / LEVELING AND PORE CLOSING LAYER EQUIPMENT - Pour the mixed Product onto the backing layer. Note: Consumption is specified in the "Application Information" section.
- Apply the Product evenly to the surface with a rubber squeegee or trowel.
CONNECTING BRIDGE - Pour the mixed Product onto the backing layer. Note: Consumption is specified in the "Application Information" section.
- Apply the Product evenly to the surface using a roller, rubber squeegee or brush.
- Uniformize by rolling with the short hair stencil in two perpendicular directions, in a cross. Note: To achieve a seamless finish, keep the "wet edge" during application.
- ( Optional ) If necessary, apply second coat of primer.
EPOXY Screed IMPORTANT It is not suitable for direct contact with water - The product is not suitable for direct contact with water unless sealed with a suitable cover. Apply the mixed product "wet on wet" on the still sticky primer. Note: Consumption is specified in the "Application Information" section.
- Spread and compact the Product with a trowel to the required thickness between the guide rails, if installed.
- Level the surface of the screed with a leveling beam that rests on the guide rails.
- Finish the surface to the required appearance using a trowel or push concrete finishers (helicopters).
REPAIR MORTAR - Apply the mixed product "wet on wet" on the still sticky primer.
- Apply the Product with a trowel/trowel to the required thickness.
- Compact the applied product with a trowel. Smooth the surface with a trowel.
- IMPORTANT Make sure that the waiting/recoating times are respected before applying the following products (See the heading "Waiting/recoating time").
CLEANING OF TOOLSClean all tools and application equipment with Sika® Thinner C immediately after use. The already hardened material can only be removed mechanically. |
