Sikafloor-122 Level is a one part, ready to use cement based self leveller. For smoothing and levelling uneven rigid internal floors prior to applying final wearing coverings such as carpets, sheet vinyl, lino, tiles, laminates and timber.

Sikafloor®-122 Level is a floor levelling compound to level or smooth screeds and concrete floors at a thickness between 6mm to featheredge. Suitable for foot traffic only.

Surface Preparation

Priming

• The one-part acrylic primer Sika® -Level-01 Primer is recommended for a pore-free surface with very good surface adhesion.
• Please refer to the relevant Data Sheet for the recommended application details etc. 

Levelling

• Apply to the required thickness up to 6mm.

Substrate Quality

• The concrete substrate must be sound and of sufficient compressive strength (min. 25 N/mm²) with a minimum pull off strength of 1.5 N/mm².
• The surface must possess an effective dampproof membrane.
• The surface should be free from residual adhesives, dampproof membranes, oil, grease, wax, loose flaky paint, dust, laitance etc. that could reduce adhesion.
• Switch off underfloor heating 24 hours before, and for 24 hours after, application.
• Ensure floor temperature is >5°C. If in doubt apply a test area first.

Substrate Preparation

• Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
• Repairs to the substrate, filling of blowholes/voids, etc must be carried out using appropriate products such as Sika MonoTop 112 MultiUse Repair Mortar.

Normal concrete / screed

• If the substrate is strong and has a sufficiently rough texture, Sikafloor®-122 Level can be applied directly onto the substrate.
• Avoid bubbles by dampening the substrate until a SSD condition is achieved.
• If the SSD option is chosen, the mechanically prepared concrete must then be thoroughly dampened during the 24 hours prior to the screed application by keeping at least 4 – 5 mm of water on the surface and letting it soak into the substrate.
• Remove the excess water prior to laying the screed.
• Any pores which may appear on the screed would indicate that the substrate was not sufficiently saturated.

Porous / Concrete Screed

• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.
• Prime as indicated above.
• For highly porous substrates it may be necessary to apply more than one coat of primer to prevent pinholes and cracking / debonding of Sikafloor®-122 Level.

Non Porous/Dense Substrates: (quarry/ceramic tiles, terrazzo and smooth concrete etc)

• Mechanically roughen surfaces by grinding or scarifying to provide a mechanical key - specialist advice and machinery may be required.

Mixing

• Unfilled (up to 6mm thick): Mix Sikafloor®-122 Level with clean water only.
• Slowly add 5 parts powder to 1 part water (25kg powder will require 5 litres / 5kg of water).
• Mix in a suitable clean container using a mechanical mixer with a spiral mixing paddle at slow speed until fully mixed and a smooth consistency achieved.
• Occasionally during hot weather the product may require remixing during the 15 - 20 minute pot life to reactivate the self-levelling characteristics.
• Do NOT add extra water.
• Discard any unused material after 20 minutes from initial mixing.

Mixing Time

• Mix thoroughly for a minimum of 3 minutes.

Mixing Tools

• Use an electric stirrer (< 500 rpm).

Application

Manual

• Pour the mixed material onto the primed surface and trowel or pin screed rake to the required thickness.
• Roll thoroughly with a spiked roller in two directions to remove any entrapped air.

Cleaning Of Equipment

• Clean all tools and application equipment with water immediately after use.
• Hardened / cured material can only be removed mechanically.

Limitations

• Very absorbent substrates must be saturated with water or primed, to prevent loss of the mixing water into the substrate which can then cause problems such as shrinkage, appearance of surface pores, or weak and dusty surfaces etc.
• Do not mix with other cements / cement based screeds or anhydrite screeds.
• Not suitable as an underfloor heating embedment layer.
• Freshly applied Sikafloor®-122 Level must be protected from damp, condensation and water for at least 24 hours.
• Do not exceed the recommended water dosage. Do not add more water when the product is starting to set.
• Do not exceed the recommended thicknesses. Not suitable for application over wood / timber or bitumen substrates.
• Due to the natural variability of the raw materials of the self-levelling screeds, the finished surface may present some colour variations.
• To ensure optimum of colour consistency, it is essential that the floor-laying operation is as clean and protected from the environment as possible.
• The surface must be sealed for a final floor finish when applied outside for best curing and aesthetic appearance.
• Temperatures below +20°C will extend the drying times.
• Not suitable for slopes or inclines > 0.5%.
• Small superficial hairline cracking or crazing is a normal occurrence under these conditions, and do not constitute a reason for claim.
• When overcoating with SikaCeram® or Sikabond® adhesives (or others), or Sikafloor® resins, additional mechanical preparation may be required to remove any cement laitance which may have formed during application due to excessive water in the mix or high ambient moisture causing bleeding.
