Prolonged vibrations and higher ambient temperatures during transportation can
result in settling of the A Component, which makes mixing more difficult.
Prolonged storage at low temperatures can result in crystallizing of the B
Component.

Consumption / Dosage
These figures are theoretical and do not allow for any additional material due to
surface porosity, surface profile, variations in level and wastage etc.
Substrate Quality
Concrete substrates must be sound and of sufficient compressive strength
(minimum 25 N/mm2 ) with a minimum pull off strength of 1.5 N/mm2 .
The substrate must be clean, dry and free of all contaminants such as dirt, oil,
grease, coatings and surface treatments, etc.
If in doubt, apply a test area first. 3

Sikafloor®-330
Substrate Preparation
Concrete substrates must be prepared mechanically using abrasive blast cleaning
or scarifying equipment to remove cement laitance and achieve an open textured
surface.
Weak concrete must be removed and surface defects such as blowholes and voids
must be fully exposed.
Repairs to the substrate, filling of blowholes/voids and surface levelling must be
carried out using appropriate products from the Sikafloor® , SikaDur® and SikaGard®
range of materials.
The concrete or screed substrate has to be primed or levelled in order to achieve an
even surface.
High spots must be removed by e.g. grinding.
All dust, loose and friable material must be completely removed from all surfaces
before application of the product, preferably by brush and/or vacuum.
Application
Conditions /
Limitations
Substrate Temperature
+10°C min. / +30°C max.
Ambient Temperature
+10°C min. / +30°C max.
Substrate Moisture
Content
< 4% pbw moisture content.
Test method: Sika® -Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).
Relative Air Humidity
80% r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3°C above dew point to reduce the
risk of condensation or blooming on the floor finish.
Application
Instructions
Mixing
Part A : part B = 79 : 21 (by weight)
Mixing Time
Check if the B component is free of crystallization. Should crystals be found the B
component has to be heated to 60°C until all crystals redissolve.
Prior to mixing, stir part A mechanically. When all of part B has been added to part
A, mix continuously for 2 minutes until a uniform mix has been achieved.
To ensure thorough mixing pour materials into another container and mix again to
achieve a consistent mix.
Over mixing must be avoided to minimise air entrainment.
Mixing Tools
Sikafloor® -330 must be thoroughly mixed using a low speed electric stirrer (300 -
400 rpm) or other suitable equipment.
Application Method /
Tools
Prior to application, confirm substrate moisture content, r.h. and dew point.
If > 4% pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B.
(temporary moisture barrier) system.
Levelling:
Rough surfaces need to be levelled first. Therefore use e.g. Sikafloor® -161 levelling
mortar (see PDS).
Self-smoothing system 2.0 mm:
Sikafloor® -330 is poured and spread evenly by means of a serrated trowel. Roll
immediately in two directions with a spiked roller to ensure even thickness and to
remove entrapped air.
Once Sikafloor® -330 is “tack-free” apply the seal coat.
Seal coat:
Top coats are uniformly spread using a short pile roller.
A seamless finish can be achieved if a “wet” edge is maintained during application.4

particularly temperature and relative humidity.
Notes on Application /
Limitations
Do not apply Sikafloor® -330 on substrates with rising moisture.
Do not apply on substrate surfaces with a slope > 1%.
Freshly applied Sikafloor® -330 must be protected from damp, condensation and
water for at least 24 hours.
Avoid puddles on the surface with the primer.
Uncured material reacts in contact with water (foaming). During application care
must be taken that no sweat drops into fresh Sikafloor® -330 (wear head and wrist
bands)

If heating is required do not use gas, oil, paraffin or other fossil fuel heaters, these
produce large quantities of both CO2 and H2O water vapour, which may adversely
affect the finish. For heating use only electric powered warm air blower systems

Cleaning /
Maintenance
Methods
To maintain the appearance of the floor after application, Sikafloor® -330 must have
all spillages removed immediately and be regularly cleaned using rotary brush,
mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum
techniques etc using suitable detergents and waxes.
