Resistant to wide rang of general chemicals and acids .

For severe conditions , please refer to Sika`s Representative

Short-term moist/wet heat* up to +80 °C where exposure is only occasional (steam cleaning etc.).

*No simultaneous chemical and mechanical exposure and only in combination with Sikafloor® systems as a broadcast system with approx. 3–4 mm thickness.

+10 °C min. / +30 °C max.

80 % r.h. max.

Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish. Low temperatures and high humidity conditions increase the probability of blooming.

+10 °C min. / +30 °C max.

≤ 6 % pbw moisture content using the Sika® - Tramex meter (at the time of application).

Note the moisture content must be ≤ 4 % pbw when using the CM measurement or Oven-dry-method. Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

Before applying solvent based products on Sikafloor®-161 allow:

Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

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

Prior to mixing all parts, mix separately part A (resin) using a low speed single paddle electric stirrer (300 - 400 rpm). Add part B (hardener) to part A and mix it together continuously for 2-3 minutes until a uniform mix has been achieved. When parts A and B have been mixed , gradually add the appropriate granulometry of dried quartz sand and if required Extender T.

Mix for a further 2 - 3 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again 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 flat or straight edge trowel at least once to ensure complete mixing.

For more details or clarification , please refer to Sika`s Technical Team .

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. If moisture content > 6% parts by weight, Sikafloor® EpoCem® may be applied as a Temporary Moisture Barrier (T.M.B.) system.

Primer

Pour mixed Sikafloor®-161 onto the prepared substrate and apply by brush, roller or squeegee then back roller in two directions at right angles to each other. Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats.

Confirm primer waiting /overcoating time has been achieved before applying subsequent products.

Surface Sealer ( Scratch Layer )
Spread the mix Sikafloor®-161 with fine filler ( K4 ) using notched trowel as a scratch coat .

Epoxy screed / repair mortar
Apply the repair or screed mortar onto the “tacky” primer layer . For the screed, use levelling battens and screed rails as necessary. After a short waiting time, compact and smoothen the mortar with a trowel. For the screed, a teflon coated power float (~20 - 90 rpm) is recommended.

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