SikaLevel Self Leveling Underlayment
How-To-Use
Materials:
• Safety glasses and gloves
• 50 lb. bag of SikaLevel Self Leveling Underlayment
• Sufcient water for desired mix
• Drill, mixing container and mixing paddle
• Rake / Leveler (for spreading material)
Procedure (Refer to Product Data Sheet for more information)
1. Remember to always wear waterproof gloves and safety goggles whenever mixing
or using cement-based products.
2. Pour 1 gallon of cool, potable water into a suitably sized and clean mixing con-
tainer, using a calibrated measuring jug, or similar, to ensure strict control of the
water content (avoid over-watering). Cool water 70°F serves to maximize the work-
ing time; if available water is not at this temperature, then consideration should be
given to cooling the water. Add Sika Level to the water, while slowly stirring, adding
the complete contents of the 50 lb. sack. Once all the powder has been added,
continue mixing until a lump-free and uniform consistency is achieved. If mixing
in a barrel or similar container, employ the water to powder ratio as stated above
and use a low speed electric mixer (300 to 450 rpm) and egg beater style mixing
paddle to blend water and powder for a minimum of 3 minutes, until a uniform mix
has been produced.
3. Prior to placing the underlayment, ensure that all sources of premature drying or
direct sunlight are blocked off to avoid accelerated curing and reduced physical
properties. The stated ambient and substrate application temperatures are to be
achieved before installation and should be maintained for a period of at least 3
days thereafter. Should colder conditions prevail, make allowances for the use of
indirect and vented heaters to achieve and maintain the application temperatures
required. Where temperatures exceed 86°F (30°C), refer to and follow ACI hot
weather application and protection guidelines. Before laying the material, organize
labor to operate most effectively, ensuring that installers can maintain a continuous
ow of material and avoid creating cold joints. The dimensions of the pour, in terms
of width, should also be set accordingly.
4. Suitable for overcoating with impermeable moisture sensitive oors after drying
(max. 3% humidity); normally reached after 24 hours. Suitable for overcoating with
tiles or other moisture insensitive oor covering after 2-3 hours. Suitable for wood
oor bonding at 1/8 inch (3 mm) thickness after 24 hours. Times are approximate
and at 73ºF(+23ºC) and 50% R.H. and thus will be affected by changing substrate
and ambient conditions, particularly the temperature and relative humidity. When
overcoating Sika® Level always ensure the moisture content has achieved the
required value for the coating product, as the waiting time will vary with the applica-
tion thickness and ambient humidity. (Refer to the top coat product data sheet).
Typical moisture content of the product should be <4% prior to overcoating. Other
test recommended by oor covering manufacturer should be used as the nal
decision making tool.
