Caution:
The end of the product’s potlife is not noticeable! Keep within the limitations mentioned below. Discard material not used within these times.

Before applying Sikafloor®-291 on Sikafloor®-290 Primer allow:

Times are approximate at 75% r.h. and will be affected by changing ambient and substrate conditions, particularly temperature and relative humidity.

No specific additional curing measures are required.

All times are approximate and will be affected by changing ambient and substrate
conditions

0.20 – 0.40 kg/m2/coat.

This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variation in level or wastage, etc.

Low speed electric stirrer (~ 300 – 400 rpm) with helical paddle or other suitable equipment.

Prior to mixing, shake part A and part B briefly until homogenous, then pour both parts into the mixing container and mix thoroughly for 3 minutes until a uniform mix has been achieved.

Pour the mixed material into another container carefully scraping the sides and mixing paddle with a spatula and then mix again briefly to ensure complete and thorough mixing.

Excessive mixing must also be avoided to minimise air entrainment.

Apply Sikafloor®-290 Primer by suitable brush, roller or trowel and overwork with a roller.

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
