Primers are formulated for bonding porous and disintegrating parts of mineral substrates, walls and floor systems, thus improving the adhesion of the surface. By closing up the pores in substrates it considerably reduces and balances the hygroscopic properties of the surface in absorbent areas, and prevents gypsum-based plasters and skimming plasters from burning out. It can be applied over mineral substrates and dispersion paints as a protective coat in interior areas. <\/span><\/p>\n [\/et_pb_accordion_item][\/et_pb_accordion][et_pb_heading title=”Floor screeds” _builder_version=”4.27.5″ _module_preset=”default” title_level=”h3″ global_colors_info=”{}”][\/et_pb_heading][et_pb_accordion toggle_icon=”C||divi||400″ admin_label=”Aljzatkiegyenl\u00edt\u0151k” module_class=”gyik-harmonika” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_accordion_item title=” How long does it take for \u201dSz\u00e9ria\u201d to set to light foot traffic and what is the waiting time before subsequent bonding” open=”on” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n It depends on the thicknesses applied and on the ambient conditions (e.g. temperature, humidity), generally in about 8 hours the surface sets to light foot traffic and is ready for finishing in about 24 hours. <\/p>\n [\/et_pb_accordion_item][et_pb_accordion_item title=”How does an anhydrite-base floor screed differ from a cement-base floor screed?” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n The anhydrite (calcium sulphate) base floor screed has better spreading properties.

Keramod 125 plaster of Paris can be used for making a wide range of ceramics. To complement its broad spectrum of uses we also recommend our casting plaster products for use besides Keramod 125, which provide an ideal solution for every need in ceramics production.

According to MSZ 57:1977, the beginning of the setting time must be over 6 minutes, and the end of the setting time must be under 20 minutes.
