Suitable for use with underfloor heating systems

1 gallon (3.79 L) of water per 50 lb. (22.7 kg) bag

• 1/8” up to 2” (3 up to 50 mm)
• Can be extended with pre-washed 3/8” pea-gravel up to 2.5” (64 mm)

41–86 °F (5–30 °C)

For application, between 41–86 °F (5–30 °C)

Approx. 25 minutes

Foot Traffic: 2–3 hours for foot traffic
 

Ready for Covering:

• Tile/Stone/non-moisture sensitive flooring: 2–3 hours
• PVC/ Carpet/Vinyl/Rubber flooring: 1 day
• Hardwood/Engineered Wood flooring: 3 days

For coatings (ex. epoxy):

• 1/8" depth: 3 to 4 days
• 1/2" depth: 7 to 8 days
• Over 1/2" depth: 14 to 15 days

Please consult coating manufacturers for recommendations. It is always important to check the moisture content of the floor/slab before applying a coating. Meeting the specifications of the manufacturer. This can be done with a moisture meter.

(Coverage figures do no include allowance for surface profile and porosity or material waste)

Pour 1 gallon (4 quarts) of cool potable water (70 °F) 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-watering). If available water is not at this temperature, then consideration should be given to cooling/heating the water. Add SikaLevel® to the water, while slowly stirring, adding the complete contents of the 50 lb. bags.

Mix with a high-speed drill (more than 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.

Pour the mix and spread using a smoothing trowel. Even surfaces are easily achieved using a pin leveler. In higher thickness using a spike roller is recommended. Avoid contact to vertical structures by putting in an edge strip such as foam tape.

If a second layer of leveling compound has to be applied, prime the first layer with Sika® Level Primer when the first layer is walkable. The maximum layer thickness must not be exceeded in case of two layer applications. The second layer must not exceed the layer thickness of the first layer.

Protect curing SikaLevel® layers from high ambient temperatures, direct sunlight and ensure an adequate air circulation.

The cured surface of SikaLevel® must be protected from any type of contamination by installing a suitable coating. Always install an adequate number of properly located test areas, to include the finish flooring, to determine the suitability of the product for its intended use. 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. Low substrate temperatures and/or high ambient humidity require longer drying times for primers. SikaLevel® is not intended to be use as a wear layer.

All cement based products have the potential for cracking. Cracking, such as hair line cracking cannot be considered as a product defect or installation failure.

For large scale areas that require deeper applications, the following recommendations can be used to minimize material cost:

1. The material can be extended by adding up to 30 % of 20/30 grade sand during mixing to achieve up to 2” in one lift. A reduction in flow, approximately 15 %, can be expected. The final layer should be neat to allow for a smooth finished floor. When adding aggregate, expect coverage to increase by approximately .16 cu.ft. per 25 lbs of aggregate.

2. Pre-washed 3/8” pea-gravel can be pre-placed into the area being leveled allowing for up to 2” in one lift. Applicator must be aware that the aggregate can cause voids in the underlayment if not filled correctly. When adding aggregate, expect coverage to increase by approximately .16 cu.ft. per 25 lbs of aggregate. Multiple lifts can also be applied to achieve greater depths, making sure to prime with Sika® Level Primer in between lifts. If necessary, further detailed recommendations can be obtained by calling Sika Corporation’s Technical Service Department. Over large areas, application by conventional piston, rotor-stator or underlayment type pumps is more appropriate. Thoroughly spike roll in two directions (90 °) to remove installation marks and any entrapped air, but avoid overworking.

Clean tools in water immediately.
