Vetonit remokor N-40 — thixotropic levelling mortar, class R3

Thixotropic repair mortars

Vetonit remokor N-40 serves for levelling and fine finishing of reinforced concrete and for protecting it against aggressive media. It is a non-shrink fine-grained thixotropic class R3 mortar based on cement, sand up to 0.63 mm and polymer fibre, applied with a trowel or by wet spraying, including on vertical and overhead surfaces. After 28 days the compressive strength is at least 40 MPa, water impermeability W12, frost resistance F₁300; the mortar is used in transport and hydraulic engineering construction.

Typethixotropic repair mortars
Useindustrial buildings, hydraulic structures and dams
Basedry mix based on cement, graded sand (maximum size 0.63 mm) and special additives with polymer fibre; non-shrink fine-grained thixotropic compound
Colourgrey
Packagingthree-ply paper bag with a polyethylene middle ply, 25 kg
Application methodclean the concrete, remove weak areas (grinding, milling, sandblasting, wet abrasive blasting, shot blasting), wash with pressurised water; clean the rebar and immediately coat it with “Vetonit remokor 05”; dampen the substrate 24 h beforehand and again before the work (matt-damp); water +10…+30 °C, mortar temperature +10…+20 °C; first the minimum amount of water, then the dry mix, mix for 3–5 min with a drill and low-speed paddle or in a concrete mixer, pause 5 min, remix, add the rest of the water if necessary; do not overdose water; mechanically with a plastering machine (wet spraying) or by hand with a trowel; without “remokor 05” a primer coat of the same mortar in a more fluid consistency is mandatory, scrubbed in with a stiff brush, main layer “wet on wet”; smooth with a float after setting; thicker than recommended — in several layers
Application temperature+5…+35 °C (air and substrate)
Curingkeep moist, protect from precipitation, sun and wind for 5 days; a film-forming curing compound may be used; for 5 days after the work the air and substrate temperature must not be below +5 °C
