(Coverage figures do not include allowance for surface profile and porosity or material waste)
MIXING
- Before applying, thoroughly shake the container in which the material is supplied to agitate the contents, ensure all solids are distributed throughout the dispersion and a uniform consistency is achieved.
APPLICATION
- Apply Sika® Level-02 EZ Primer undiluted with a 1/4” nap roller, working the material into the prepared substrate.
- Typically, one single application is required.
- Ponding of the primer on the surface must be avoided and puddles must be removed.
- Where temperatures exceed 86 °F (30 °C), refer to and follow ACI hot weather application and protection guidelines.
- Should colder conditions prevail, make allowance for the use of indirect and vented heaters to achieve and maintain the application temperature required.
CLEANING OF TOOLS
- Clean tools in water immediately.
FAQ
No, they are not. For standard-size tile < 15”, the substrate flatness tolerance is no more than ¼” variance in 10”. For tile > 15”, the substrate flatness tolerance is no more than 1/8” variance in 10’. This applies to any substrate whether it is a wall, floor, ceiling etc.
No. Thinset is an adhesive, not a patching or leveling compound. Thinsets are
designed to be a certain thickness and when that thickness is greater than what the thinset can handle, shrinking will occur. Use a product that is designed for patching or leveling.
Almost all self-leveling underlayments require a primer. A primer helps with drying, flowability and bonding. Check with the manufacturer to see if the selected SLU needs a primer. For SikaLevel® SLUs, a primer is required for each pour.
Some old “cutback” black residues may contain asbestos. If the residue has asbestos, a professional will need to remove it. If the black residue does not contain asbestos, it may be removed by mechanical means such as sand blasting or grinding. Some products can encapsulate the black residue, preventing mechanical removal. Check Technical Services to find the correct products.
In most cases, flat is better than level. For example, an exterior deck needs to be flat and not level. Building codes require the deck to be pitched away from the building, which would make the deck not level. But, to install tile the deck must be flat. So, it all depends on the application.
When a flooring substrate does not meet industry flatness tolerances or when a substrate needs to be raised/lifted. Every self-leveling underlayment has a thickness threshold it can be used for. Speak with a SikaTile® Technical Representative for assistance.
