+18 °C min / +30 °C max

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.

Levelling (scratch coat) is optional, depending on substrate conditions, but it is necessary to have a good floor flatness to achieve best Sikafloor®-263 SL Décor Systems aesthetic.
Use of Sikafloor® -304 W, clear matt sealer is recommended when improved UV stability and scratch resistance are required. (please consult product data sheet)
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
Application steps

MIXING

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.

When parts A and B have been mixed, Add part C and D and carry out additional mixing for 2 minutes until a uniform consistency 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®-263 SL Décor must be thoroughly mixed using a low speed stirrer (300 – 400 rpm) or other suitable equipment.

 

APPLICATION

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 HC levelling mortar (see PDS).


Self-smoothing wearing course:
Sikafloor®-263 SL Décor mixture is poured, spread evenly by means of a large surface scraper (preferably with pins rather than teeth). The scrapper is then turned down for gently smoothing the spread material.

Roll immediately in two directions with a spiked roller to ensure even thickness and to remove entrapped air


Matt Sealer Coat (if needed):
For areas to be particularly exposed to traffic, light grinding of Sikafloor®-263 SL Décor prior application of Sikafloor®-304 W can be recommended. On a clean, dustfree surface, Sikafloor®-304 W shall then be uniformly spread and apply using short pile nylon roller. Please consult product data sheet for mixing and application details.

CLEANING OF TOOLS

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

CLEANING

To maintain the appearance of the floor after application, Sikafloor®-263 SL Décor System must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc. using suitable detergents and waxes.
