The product must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between +5 °C and +30 °C.

All Density values at +23 °C

Resistant to many chemicals. Contact Sika Technical Services for additional information.

Part A : Part B = 80 : 20  (by weight)

+10 °C min. / +30 °C max.

80 % max.

Beware of condensation.
The substrate and uncured applied floor must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.

+10 °C min. / +30 °C max.

Surface of broadcast system to be sealed must be dry

General

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Prior to mixing all parts, mix Part A (resin) using a low speed single paddle electric stirrer (300 - 400 rpm) or other suitable equipment to mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Add Part B (hardener) to Part A and mix Part A + B continuously for 3,0 minutes until a uniformly coloured mix has been achieved. To ensure thorough mixing pour materials into a clean container and mix again for at least 1,0 minute to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = ~4,0 minutes.

Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Prior to application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures.

After waiting the appropriate overcoating time, pour the mixed Sikafloor®-356 N onto the existing resin layer and spread evenly using a short piled nylon roller in two directions at right angles to each other.

General

A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

Clean all tools and application equipment with Thinner C immediately after use. Hardened material can only be removed mechanically.
