Product Information

Chemical Base

Cement-based, polymer-modified binder system and fillers

Shelf Life

12 months from the date of production if stored properly in original, unopened, and undamaged sealed packaging

Storage Conditions

Store dry at 41–86 °F (5–30 °C)

Protect from moisture. If damp, discard the material

Technical Information

Compressive Strength

1 day 5,000 psi (34.5 MPa)
7 days 5,500 psi (38 MPa)
28 days 7,600 psi (52.4 MPa)

Flexural Strength

28 days 1,600 psi (11 MPa)

Tensile Adhesion Strength

3 days at 1/8" 400 psi (2.8 MPa)

Application

Mixing Ratio

6-6.3 qt (5,75-6,0 L)

Fresh mortar density

118 lb/ft(1.8 kg/l) (ASTM C-138)

Layer Thickness

Min. Max.
Neat 1/16” (1.5 mm) 1/2” (12.7 mm)
Extended 1/4'' (6.3 mm) 1'' (25 mm)

 

Product Temperature

65–75 °F (18–24 °C)

Ambient Air Temperature

41–86 °F (5–30 °C)

 

Note: When using water-based adhesives on the finished product the best results will be achieved at ambient and substrate temperatures between 59 and 77 °F (15–25 °C).

Relative Air Humidity

< 75 %

 

Note: The substrate and uncured product applied on the floor, must be at least 5 °F above the dew point to reduce the risk of condensation, blooming, or cement laitance forming on the surface.

Substrate Temperature

41–86 °F (5–30 °C)

Pot Life

~ 25 minutes

As the temperature will affect the pot life, application temperature:

  • 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.

Waiting / Recoat Times

Walk-on time: 1–1.5 hours

 

Suitable for overcoating with:

Non-moisture-sensitive floor covering 1.5–2 hours
Polyurethane adhesives 12 hours up to 1/8" (9.5 mm)*

 

*Mat test (ASTM D-4263) above 3/8" (9.5 mm)

The actual times will be affected by changing substrate and ambient conditions, particularly the temperature and relative humidity, plus the thickness of the material applied. When overcoating Sika® Level-525 Rapid always ensure the moisture content has achieved the required value for the subsequent floor finish adhesive/product being used, as the necessary waiting time will vary (with the application thickness and ambient humidity). Also please refer to the floor finish/adhesive PDS.

 

Consumption

Coverage

30 ft2 at 1/4” (2.78 m2 at 6 mm) per bag

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

Application Steps

APPLICATION INSTRUCTIONS

All substrates must be dry, stable, sound, and free of all contaminants such as grease, oil, paint, wax, dust, curing, and sealing compounds that will interfere with the penetration of the primer and the adhesion of Sika® Level-525 Rapid.

MIXING

  • Pour 6 qt (5.7 L) of cool 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 this temperature, then consideration should be given to cooling/heating the water.
  • Add Sika® Level-525 Rapid to the water, while slowly mixing, adding the complete contents of the bag.
  • Mix with a high-speed drill (> 650 rpm) and an egg-beater-style mixing paddle to blend water and powder for approximately 3 minutes, until a lump-free and uniform mix has been produced.
  • Do not overmix or allow the paddle to rise above the level of material as this will introduce and entrap air into the mix, potentially shortening the working life or causing pin-holing in the underlayment.
  • Let the mixed material stand until the majority of air bubbles have dispersed.

APPLICATION

  • Pour the mix and spread using a smoothing trowel. Even surfaces are easily achieved using a pin leveler.
  • It’s not recommended to remove troweling defects or to level more than once.
  • If the second layer of leveling compound has to be applied, prime the first layer with Sika® Level-01 Primer Plus (1:1) when the first layer is walkable. The maximum layer thickness must not be exceeded in the case of two-layer applications and the second layer must not exceed the layer thickness of the first layer.

 

  • Protect curing Sika® Level-525 Rapid layers from high ambient temperatures, and direct sunlight and ensure adequate air circulation.
  • Sika® Level-525 Rapid does not provide an aesthetic finish and is not intended to be used as a wear layer even if coated or sealed. Sika® Level-525 Rapid must be protected from any type of contamination by installing a suitable floor covering like ceramic tiles, carpet, VCT, wood floor, etc.
  • Always install an adequate number of properly located test areas, including the finish flooring.
  • As floor coverings vary, always contact and rely upon the floor covering manufacturer for specific directions such as maximum allowable moisture content, adhesive selection, and intended end use of the product.

CLEANING OF TOOLS

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