Elakor-PU Shpatlevka-2K — coloured polyurethane filler for substrate repair

Concrete floor repair

This coloured filler based on urethane prepolymers fills cavities, potholes, cracks and expansion joints and also smooths the surface before a polyurethane coating. It is applied with flat trowels neat or mixed with dry sand onto primed concrete, sand-cement, brick, wood and metal. Base colour is grey, close to RAL 7040; non-volatile content is at least 98 %, adhesion to concrete at least 1.5 MPa, Shore D hardness 41–46.
