Elakor-PU Siler — polyurethane curing compound for fresh concrete

Concrete impregnations and hardeners

Siler is applied to fresh concrete, topping, sand-cement or polymer-cement right after trowelling, as soon as the surface can be walked on. The film prevents moisture from evaporating quickly and prevents cracking, so further curing — covering with film or wetting — is not needed. By the ASTM C309 method, moisture loss is 4.5–5.0 g/100 cm² against a limit of not more than 5.5 for toppings; the compound is vapour-permeable and is also used outdoors at +5…+30 °C.

ManufacturerElakor — OOO “TEOKHIM-PROM”, Moscow Region
Typeconcrete impregnations and hardeners
Useoutdoor areas
Basepolyurethane moisture-retaining impregnation (membrane-forming curing compound) for toppings and freshly laid concrete
Colourtransparent liquid
Application methodCuring of freshly laid concrete, topping, sand-cement, polymer-cement: the film prevents rapid evaporation of moisture and cracking, no further curing (film, wetting) is needed. Applied to a surface finished with power trowels, firm enough for workers to walk on, without puddles; to damp ground concrete 1-2 days after placing; vapour-permeable – can be used without underlying waterproofing and outdoors. Rollers, brushes, airless spraying, 1 coat.
Application temperatureair and surface: from +5°C to +30°C; Siler temperature: from +10°C to +25°C
Curingdrying time at surface temperature: +5°…+15°C – 60…40 min; +15°…+25°C – 40..20 min
