Elakor-PU Shpatlevka-2K BP — unpigmented polyurethane filler

Concrete floor repair

The unpigmented version has a natural dark grey colour close to RAL 7005 and is intended for layers that are later covered with a topcoat. Like the coloured filler, it fills cavities, potholes, cracks and expansion joints and levels concrete, sand-cement, brick, wood and metal when installing polyurethane floors. Tensile strength after 28 days is at least 12 MPa, Shore D hardness 55–65, adhesion to concrete at least 1.5 MPa.
