Overview


Horizontal - Sika® Level SkimCoat

Fast setting, cement based smoothing and finishing compound

Sika® Level SkimCoat is a one-component, easy to use and fast drying, cementitious skim mortar ideal for the repair or reprofiling of concrete, approved wood subfloors, and correctly prepared ceramic or quarry tiles before the installation of Sika® Level products or final floor coverings. Can be installed as a true featheredge as well as filling voids and leveling defects up to 1/2” (13 mm) in depth.

  • Easy to prepare and quick to apply
  • Repairs new and renovate old floors
  • Good adhesion to substrates, subfloors and stable adhesive residue
  • Rapid setting; receives primers, levelers, adhesives and coverings without delay
  • Excellent standard of finish can be achieved to allow direct application of coverings
  • Unlimited MVER (Moisture Vapor Emission Rate)

Usage

  • Used to reprofile substrates or subfloor surfaces from feather edge to 1/2” (13 mm) prior to applying Sika® Level products or floor finishes
  • Repair minor defects, holes, cracks and pre-fill non-moving joints and seams in concrete and wood substrates
  • Suitable for use with radiant heating systems

Protect from moisture. If damp, discard material

Application

Application Information

Mixing Ratio

2 qts (1.9 L) of water per bag

Product Temperature

65-75 °F (18-24 °C)

Ambient Air Temperature

50-86 °F (10-30 °C)

Where temperatures exceed 86 °F (30 °C), refer to and follow ACI hot weather application and protection guidelines.

Relative Air Humidity

< 75%

Substrate Temperature

50-86 °F (10-30 °C)

Pot Life

~ 10-20 minutes

The temperature will affect the pot life:

  • Above 73 °F (23 °C) will reduce the pot life and the working time.

  • Below 73 °F (23 °C) will extend the pot life and the working time.

Consumption

Coverage

35 ft2 at 1/8” depth (3.2 m2 at 3 mm)

(Coverage figures do not include allowance for surface profile and porosity or material waste)

Application Steps

MIXING
  • As with all prebagged cement products, some settlement may have occurred during storage and transportation and dry blending of the material is recommended.
  • Pour 2 quarts (1.9 L) of potable water (~ 70 °F, 21.1 °C) into a suitably sized and clean mixing container, using a calibrated measuring jug, or similar, to ensure strict control of the water content (do not over-water). If available water is not at 70 °F (21.1 °C), then consideration should be given to cooling/heating the water. Add Sika® Level SkimCoatto the water, while slowly mixing, adding the complete contents of the 10 lb. (4.5 kg) bag.
  • Mixing with a high-speed drill (> 600 rpm) and a mortar/grout mixing paddle to blend water and powder for 2-3 minutes, continue mixing until a lump-free uniform mix has been produced.
  • Smaller volumes can also be mixed by hand for 2-3 minutes with a ratio of 3:1 part water. Mix until a uniform, lump free and smooth consistency is achieved.
  • Avoid entrapment of air and excessive mixing as this will impact performance. Do not mix more mortar than can be used within the stated pot life and working time, taking into consideration ambient temperatures.
APPLICATION
  • Using a flat edge steel trowel, apply Sika® Level SkimCoat immediately following mixing.
  • Ensure that the compound is tightly trowelled into all defects, seams, and non-moving joints or across roughened surfaces as required.
  • Where defects, details or roughened surfaces require repair or reprofiling to a depth greater than 1/2” (13 mm), use the appropriate Sika® Level SkimCoat Level products.
