Flex R20 Unmodified Mortar 22,7kg White
Flex R20 Unmodified professionnal mortar (22,7kg) - white

FLEX R-20 UNMODIFIED MORTAR First and foremost, it is very important to specify that for outdoor installations, TTMAC standards indicate that the temperature must reach a minimum of 12°C* throughout the entire 28-day curing period. Additionally, during hot summer days, it is preferable not to carry out an installation when the sun is shining directly on the mortar. The mortar will dry more quickly on the surface, thereby reducing the open drying time, which could limit its adhesion. As the name suggests, unmodified mortar is a mortar that does not contain polymers, which limits its use: it can only be installed on indoor concrete. However, SCHLUTER® Systems recommends its use on DITRA® and KERDI® membranes. Why unmodified mortar? According to data provided by SCHLUTER® Systems, the use of polymer-modified mortar is not recommended on DITRA® or KERDI® membranes because it requires air circulation to complete its curing process. When the mortar is trapped between two waterproof layers such as DITRA® or KERDI® membranes and porcelain, curing can only occur through moisture evaporation through the joints. In this case, an extended curing time should be allowed before grout application. If an additional curing time is not respected, the results could be unpredictable. On the other hand, unmodified mortar consists of a chemical cure that is not affected by moisture levels. Unmodified mortar is therefore the best choice for this type of application. The mix SCHLUTER® Systems recommends preparing a more liquid mix for the installation of their membranes and to adhere to the ratios indicated on the mortar bags for tile installation. Flex R20 features HYBRID technology providing resistance to sagging and is specially designed for SCHLUTER® SYSTEMS products while meeting or exceeding ANSI A 118.1 standards.
