DLX T-11 Mineral top coat, grey

DLX T-11 is a thin layer decorative plaster designed for manual, indoor and outdoor plaster works as well as building thermal insulation systems – in a so-called light & wet method. It may be used on mineral bases of all types, such as: cement surfaces, cement-lime or gypsum surfaces, gypsum boards, concrete surfaces and other. It is recommended for ARSANIT THERMA DELUX insulation systems.

It is a ready–to-use, mineral mixture of grey cement and other filling materials, as well as carefully selected aggregate fractions of proper thickness. DLX T-11 is resistant to washing and contact with water because of suitable hydrophobic agents’ content.


Sub-floor should be stable, load bearing and cleaned – free from dirt of any type. Old coats of paint or plaster of not enough adherences must be removed and any damaged plaster must be repaired. On surfaces of lime plaster, lime-cement, cement or concrete as well as reinforcement of insulation system DLX P-30 primer coat must be applied. Usage of DLX P-30 primer results in significant strengthening of base, decreasing of base absorbability and facilitation of plaster works. Wet layers of traditional cement plasters, cement-lime and lime used as primer layer should be stabilized at least for 21 days.

DLX T-11 is prepared by mixing in a container a whole bag of mortar with measured amount of water (4.5 – 5.0 l per one 25 kg bag). Mortar must be mechanically stirred until homogenous consistency is obtained. The mortar may be applied after 10 minutes and stirring it once again. Repeated stirring may help in obtaining consistency proper to conditions in which the mortar will be applied. Prepared mortar must be used within 1.5 hour. It is recommended to stir the mortar time to time during its application in order to unify its consistency.

Apply a grain-thick layer of plaster on prepared surface by means of a smooth float. Remove exceeding amount of mortar. After a proper time lapse dependant on conditions of application (base absorptivity, ambient temperature and mortar consistency) give the plaster required texture by means of plastic float. After a short period of time, when the mortar no longer adhere itself to the float, it is possible to create texture by means of plastic float held flat. Plaster may be floated vertically, horizontally, with circular movements or crossing directions what gives you possibility to create different textures. The plaster should be applied “wet on wet” method, in order to avoid creating vivid cut off lines. Plan the job in a manner enabling creation of technological joints in building corners or structural bends, under downpipes, on contact of different colours etc. Protect surface being plastered against direct sunlight, winds and precipitation during plaster works and afterwards. Plaster drying period dependant from base material and ambient conditions is… During plastering works and plaster drying ambient temperature should be kept within range from +5 to +250C. Plastered surface may be painted using facade paints after 2 to 6 weeks from plastering works finish.
