with added aggregate

®
Construction

Product Sikafloor Level -50 is Ready to used High Performace Cementitious with added
Aggregate, pumpable, low dusting, self-Levelling high performance cementitious
Description underlayment for the levelling and smoothing of interior floors prior to the
application of the final floor finish.
®
Uses Sikafloor Level -50 can be applied manually or by pump to level floors at a thick,
prior to subsequent finishing with epoxy or PU or PMMA system, ceramic or stone
tiles, PVC sheet, wood flooring or carpets, etc.

System
Information
Productiveness 25 kg of dry mix yields approx. 11 l of concrete

Application Details
Consumption / Dosage 2.5 to 3.0 l of water per 25 kg bag dependent on the desired flow.

Substrate Quality The concrete substrate must be sound and of sufficient compressive strength
2 2
(min. 25 N/mm ) with a minimum pull off strength of 1.5 N/mm .
The surface must be clean, dry and free of all contaminants e.g. dirt, oils, grease,
coatings and surface treatments etc.
If in doubt apply a test area first.
Substrate Preparation / Concrete substrates must be prepared mechanically using abrasive blast cleaning
Bonding or scarifying equipment to remove cement laitance and achieve an open textured
surface.
Weak concrete must be removed
All dust, loose and friable material must be completely removed from all surfaces
before application of the product, preferably by brush and/or vacuum.
The substrate can be in a SSD condition, but there must be no rising moisture prior
to the dampening operation, according to ASTM D 4263 (Polyethylene-sheet test).
Used SBR or Acrylic Polymer Bonding or Epoxy Bonding Based for Bonding

Application
Instructions
Mixing When mixing manually add the dry powder (25 kg) into a container with the clean
water. The water required is 10 - 12% or between 2.5 and 3 l per 25 kg bag
Using Pan mixer : Mix dry concrete for a few seconds, then add mixing water.
Mix with low-speed for 3 minutes.

Using Hand mixer : Put appropriate quantity of water (depend on the desired flow)
®
into a mixing vessel. Add slowly the total content mortar of Sikafloor level-08
while mixing. Mix continuously for 2 minutes, then add the aggregate. Add mixing
time 1 more minutes. Use a mechanically low speed drill (400–600 rpm) with mixing
paddle.

Curing After pouring, need wet cure for a minimum 3 days with wet hessian, plastic sheet
or apply a curing compound (Antisol S).
Cleaning of Tools Clean all tools and application equipment with water immediately after use.
Hardened / cured material can only be removed mechanically.

Pot life
Conditions Time
+30°C / 50% r.h. 30 minutes

The temperature will affect the pot life.

Application at temperatures above +30°C will reduce the pot life and the working
time. Temperatures below +30ºC will increase the pot life and extend the working
time.
Waiting Time / Suitable for overcoating with impermeable moisture sensitive floors after drying
Overcoating normally reached after 3 – 7 days depend the system of topping

 Notes on Application / Very absorbent substrates must be saturated with water or primed to prevent loss
Limitations of the mixing water into the substrate, which can cause problems such as
shrinkage, the appearance of surface pores or weak and dusty surfaces etc.
Do not mix with other cements or cement based screeds.
®
Freshly applied Sikafloor Level -50 must be protected from damp, condensation
and water for at least 24 hours.
Do not exceed the recommended water dosage. Do not add more water when the
product is starting to set.
Temperatures below +20°C extend the drying times.
®
Sikafloor Level -50 does not provide an aesthetic finish. Product must always be
overcoated or any finishing process.
Protect from direct sunlight, hot or strong winds and extremes of temperature to
avoid cracking or crazing.
® ®
When overcoating with Sikafloor or Sikabond (or others), additional mechanical
Construction

preparation may be required to remove any laitance which may have formed during
application.
For the large area, for minimize shrinkage and de-bonding / de-lamination used
shear connector every 50 cm and used Wire Mesh M6 / M8 applied the centre of
thick of Topping Concrete.
