Class R1 Fine Grade Fairing Coat for Existing Paint Finishes

Overview

Monolevel 250F is a fine grade polymer modified mortar for filling blow holes, cracks, surface defects and uneven surfaces in sound existing paint finishes as well as concrete and mosaics prior to application of Flexcrete anti-carbonation coatings.

Monolevel 250F is a single component, polymer modified cementitious mortar for the filling of blow holes, cracks, mapping defects, blemishes and levelling out uneven surfaces in existing paint finishes as well as concrete and mosaic substrates. The incorporation of a polymer promotes adhesion to existing painted surfaces, making it ideal for application to provide a fair faced finish prior to application of subsequent protective coatings and paint finishes. Once cured, the product should be overcoated with specialist membranes in the Flexcrete range to provide further protection and aesthetic quality.
