gräfix 34 fine
Flexible medium-bed adhesive · grey
C1 T · Trass-based medium-bed adhesive for mortar bed thicknesses of 5–15 mm
This polymer-modified medium-bed adhesive, based on the finest trass powder, high-quality cements (to prevent efflorescence) and crushed limestone sand up to 0.8 mm, as well as additives to improve workability, is used for laying large-format natural stone and engineered stone slabs indoors and outdoors on floors and walls where a coarser grain size distribution is required (compared to thin-bed natural stone adhesives). Substrates may be uneven and the slabs may vary in thickness.
Suitable for use with underfloor heating.
