NOTES ON INSTALLATION
- Avoid application in direct sunlight, during precipitation and/or when strong winds prevail.
- Use only clean, potable water.
- Do not use solvent-based curing compounds.
- Sika MonoTop®-410 F does not form a vapor barrier when cured.
- As with all cement-based materials, avoid contact with aluminum to prevent adverse chemical reaction and possible product failure. Insulate potential areas of contact by coating aluminum bars, rails, posts etc. with an appropriate epoxy such as Sikadur®-32 Hi-Mod.
- Elevated temperatures will decrease working time and slump.
- Rate of strength gain will be reduced at colder temperatures.
- On site testing is recommended.
SURFACE PREPARATION
- Following ICRI Guideline 310.2, the concrete surface must be clean, sound and mechanically prepared to obtain a surface profile of CSP 6-10 (ex : hydrodemolition, scarification, scabbling + sandblasting, etc.).
- Follow ICRI Guideline 310.1 for the preparation of the repair perimeter, the repair area geometry and for the cleaning of the concrete and reinforcing steel surfaces.
- Verify the absence of micro cracking following ICRI Guideline 310.2.
MIXING
- Mix using a heavy duty low speed electric drill/mixer (300 - 450 rpm) and mixing paddle (Jiffy or Exomixer®/spiral type) or a mortar mixer.
- Pour approx. 2.5 L (0.66 US gal.) of potable water in a clean mixer or pail. Add Sika MonoTop®-410 F slowly while continuing to mix.
- Mix to a uniform consistency for a maximum of three (3) minutes.
- Add additional water up to 2.7 L (0.71 US gal.) if a wetter consistency is desired.
- Do not overwater. Excessive water/cement ratios may cause severe bleeding and retardation and will reduce the strength and performance of the mortar.
- For sprayable application, contact Sika Canada.
APPLICATION
- Apply Sika MonoTop®-410 F mortar by hand trowel for the repair of horizontal, vertical or overhead concrete surfaces.
- At the time of application, the substrate surfaces must be saturated surface dry (SSD) but hold no standing water.
- A neat mix of Sika MonoTop®-410 F mortar must initially be scrubbed into the mechanically prepared, SSD substrate. Be sure to fill all pores and voids.
- Apply Sika MonoTop®-410 F mortar by hand trowel while the scrub coat is still wet and uncured.
- Force material against edges of repair, working toward center. After filling repair area, screed off excess Sika MonoTop®-410 F mortar.
- If the repair requires several lifts (layers), apply the mortar, leaving a rough profile, and then score the surface immediately in a cross-hatch pattern to a depth of approximately 6 mm (1/4 in) to provide a key. Allow the layer to achieve initial set and then apply subsequent layers as soon as the previous lift will support it without being displaced.
- Allow Sika MonoTop®-410 F to set to the desired stiffness. Finish with broom or with a burlap drag for a rough finish. Finish with a wood float for a granular finish. Finish with a steel trowel or a magnesium float for a smooth finish.
- Mixing, placing and finishing typically should not exceed 2 to 3 hours maximum.
- For sprayable application, contact Sika Canada.
CURING TREATMENT
- As per ACI 308 recommendations for Portland-cement concrete, curing is required.
- Moist curing must commence immediately after finishing.
- Moist cure for the first 24 hours only with wet burlap and/or polyethylene film or a fine mist of water may be used.
- Alternatively, apply a water-based, compatible curing compound meeting ASTM C309, such as Sika® Florseal WB-18 & -25.
- Curing compounds may adversely affect the adhesion of following layers of mortar, leveling mortars or protective coatings.
- Protect newly applied material from direct sunlight, wind, rain and frost. To prevent from freezing, cover with insulating material (e.g. curing blanket).
CLEAN UP
- Clean all tools and equipment after use with water.
- Once hardened, Sika MonoTop®-410 F can only be removed mechanically.
- Wash soiled hands and skin thoroughly in hot soapy water or use Sika® Hand Cleaner towels.
