Resistant to many chemicals. Contact Sika Technical Service for specific information.

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.

Part A : part B = 79 : 21 (by weight)

+10 °C min. / +30 °C max.

80 % r.h. max.

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.   Note: Low temperatures and high humidity conditions increase the probability of blooming.

+10 °C min. / +30 °C max.

≤ 4 % pbw

Test method: Sika®-Tramex meter, CM-measurement or Oven-dry-method.

No rising moisture according to ASTM (Polyethylene-sheet).

Before overcoating Sikafloor®-263 SL N allow:

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

~0,9–1,2 kg/m²/mm

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc. For detailed information,  refer to the system data sheets Sikafloor® Multidur ES-20 and Sikafloor® Multidur EB-27

Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved. When parts A and B have been mixed, add the quartz sand and if required  Extender T. Mix for a further 2 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. Over mixing must be avoided to minimise air entrainment.

Mixing Tools

Sikafloor®-263 SL N must be thoroughly mixed using  low speed equipment (300 - 400 rpm). Use a forced action mixer of rotating pan, paddle or trough type. Free fall mixers should not be used.

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 and dew point. If > 4% pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.
Primer:Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply Sikafloor®-156 / 161 /-160 by brush, roller or squeegee.
Preferred application is by using a squeegee and then back rolling in two directions at right angles to each other.
Levelling:
Rough surfaces need to be levelled first using Sikafloor®-156/-161/-160 levelling mortar (see PDS).
Self -Smoothing Finish:
Sikafloor®-263 SL N is poured and spread evenly using a suitable trowel/pin rake to the required thickness.
Spike roller immediately in two directions at right angles to each other to remove trowel marks, aid air release, ensure an even thickness and obtain required surface finish.
Slip Resistant Broadcast Finish:
Sikafloor®-263 SL N is poured and spread evenly using a suitable trowel/pin rake to the required thickness.
Spike roller immediately in two directions at right angles to each other to aid air release and ensure an even thickness. After about 15 minutes (at +20°C) but before 30 minutes (at +20°C), broadcast with quartz sand, at first lightly and then to excess to produce an even distribution surface profile. Allow Sikafloor®-263 SL N to initially cure and remove all loose sand by vacuum equipment. Apply a final seal/top coat of Sikafloor®-263 SL N by roller or squeegee at a consumption of 0.6 - 0.8 kg/m2 to completely encapsulate the sand. Then back roller in two directions at right angles to each other.

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