EQUIPMENT
Mixing Tools
Sikafloor®-263 SL must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment. For the preparation of epoxy mortars use a forced action mixer of rotating pan, paddle or trough type. Free fall mixers should not be used.
MIXING
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 the Extender T and 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 consistent mix. Over mixing must be avoided to minimise air entrainment.
APPLICATION
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:
Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply Sikafloor®-151 /-161 /-161 G by brush, roller or squeegee. Preferred application is by using a squeegee and then backrolling crosswise.
Levelling:
Rough surfaces need to be levelled first. Therefore, use e.g. Sikafloor®-151 /-161 /-161 G levelling mortar (see Product Data Sheet).
Wearing course smooth:
Sikafloor®-263 SL is poured, spread evenly by means of a serrated trowel or pin rake.
After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish.
Roll immediately in two directions with a spiked roller to ensure even thickness.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
