Dry building mix  ТМ MASTER C1.ЗК5 DSTU B V.2.7-126:2011

Bar-code  4820086 381185

25 kg +/-1%
Dry building reinforcement  mix for polystyrene ТМ MASTE. ARMIR designed for making a reinforcing layer for external heat insulation systems of buildings.

Surface preparation must be done in accordance with the State Building Standard of Ukraine DBN V.2.6-22-2001. The base must be:
- clean (remove dirt, flows, dust, fungal lesions with a power tool or manually, also clean from residual oils and paints);
- strong (remove all loose areas and process them with the primer ТМ MASTER or іMASTER;
- align significant irregularities in bases using the plaster or adhesive mixes for thermal insulation systems ТМ MASTER or ТМ іMASTER.

Perform the work at an air temperature of +50С to +250С. The temperature of the base must be in the same range. Facades must be protected from direct sunlight, wind and precipitation.
Add pure water to the dry mixture in an amount indicated in specifications, then mix it (use electric drills with screw socket). Leave closed mix for 5 minutes, then stir again. The closed mix is suitable for use within 120 minutes (at recommended atmospheric conditions). At high temperatures, periodically stir the closed mix to avoid reducing its mobility.
Apply the closed mix ТМ MASTER. ARMIR the surface of the polystyrene with a layer thickness of 2-3 mm using a trowel or other tools. In a layer applied, evenly and without tension insert the reinforcing mesh ТМ MASTER. Apply on the mesh the next layer with a thickness of 3-4 mm.
Apply the decorative protective layer 72 hours after the surface; before this, treat the surface with the quartz primer paint ТМ MASTER. CONTACT.
