Application
Layer Thickness
One coat of 5–6 mils (127–152 µm) Wet Film Thickness to achieve a Dry Film Thickness of 2.75–3.3 mils (70–84 µm).
Product Temperature
Condition product between 18 °C to 30 °C (65 °F to 86 °F) before use.
Ambient Air Temperature
Between 15 °C to 30 °C (59 °F to 86 °F)
Low temperatures and/or high humidity will increase curing time.
Relative Air Humidity
Maximum 75% (during application and curing).
Sikafloor® Concrete Resurfacer should not be applied when the Relative Humidity is greater than 75 % as curing times will be longer, and water will be retained in the film reducing ultimate coating performance.
IMPORTANT: Water-borne products require moisture to evaporate from the film to cure to full properties. Provide adequate fresh air ventilation to remove the excess moisture from the curing product.
Substrate Temperature
Between 15 °C to 30 °C (59 °F to 86 °F)
Pot Life
~60 minutes at 20 °C (68 °F) (Material Temperature)
Curing Time
| Susbtsrate Temperature | |||
| 10 °C (50 °F) | 23 °C (73 °F) | 30 °C (86 °F) | |
| Foot traffic | 3 days | 16-18h | 12-14h |
| Light traffic | 4 days | 22-24h | 16-18h |
| Normal traffic | 5 days | 36h | 24h |
Application Time
45 - 60 minutes at 23 °C (73 °F)
Waiting Time / Overcoating
| Susbtsrate Temperature | |||
| 10 °C (50 °F) | 23 °C (73 °F) | 30 °C (86 °F) | |
| 24-48h | 6-12h | 4-6h |
Note: If the Waiting/ Recoat time has passed the previous coat must be lightly sanded, to remove all gloss; vacuum cleaning and solvent wiping will be necessary to remove all traces of dust. The surface should be a uniform dullness, with no gloss present after clean-up and before applying the next coat.
Consumption
6.5–7.9 m2/L (263–320 ft2/US gal)
One kit will cover approximately 13.7–16.6 m2 (147–179 ft2)
Note: This is a theoritical coverage. Practical coverage rates and material consumption will depend upon porosity and profile of substrates. Allowance must be also made for variation in film thickness or number of coats required to achieve complete coverage of surfaces. Test sections are recommended to establish correct coverage.
SUBSTRATE PREPARATION
Clean existing concrete with a 2500 PSI pressure washer to remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, foreign matter, coatings and detritus (more thorough washing might be needed is any debris remains).
Concrete compressive strength should be at least 25 MPa (3625 psi) at 28 days and at least 1.5 MPa (218 psi) in traction at the time of Sikafloor® Concrete Resurfacer application.
MIXING
- Stir component A (Resin) and component B (Hardener) individually to re-disperse any settled components.
- Completely pour component B (Hardener) into component A (Resin). Mix mechanically using a low-speed drill with a helical or paddle mixer (200 - 300 rpm) for 2–3 minutes until a uniform blend is achieved. Ensure material from the sides and bottom of the container is fully incorporated. Be careful not to introduce any air bubbles while mixing.
- Gradually add component C (Sand aggregates) into the mixed resin while continuing to mix. Mix for an additional 2–3 minutes or until the blend is homogeneous, lump-free, and consistent in texture.
APPLICATION
Sikafloor® Concrete Resurfacer can be applied by brush, roller or squeegee, depending on the surface to be coated and site conditions.
Apply the mixed material immediately to the edges with a brush and then use a roller or a squeegee for the rest. The specified film thickness must be achieved to ensure full coverage. Coverage rate may vary depending on the porosity and texture of the prepared substrate.
If the waiting/recoat time is exceeded (refer to the Application Information section), the previous coat must be lightly sanded to remove all gloss. After sanding, perform vacuum cleaning followed by solvent wiping to eliminate all dust and residue. The surface should exhibit a uniform dull appearance, with no remaining gloss, before applying the next coat.
CLEAN UP
Once hardened, product can only be removed mechanically. Clean tools and brushes with thinner.
