Assessment of the Type of Paint on Performance of Rendering Mortars

The aim of this work is to determine how the mechanical and physical properties render mortars, in particular their moisture performance, are affected by application paint. In study, three commercial paints, hydro-pliolite-based paint, acrylic paint silicate were applied as coating layers on mortars formulated with different binders. choice binders used (hydrated lime, natural hydraulic lime cement) was related functional requirements that renders have fulfil according type buildings where they (i.e., new or old buildings). Firstly, hardness surface cohesion painted unpainted analysed order investigate effect strength surface. influence paints behaviour then investigated using water capillarity test, vapour permeability test drying test. results show all studied can cause a significant change terms transport phenomena. Nevertheless, it be concluded has greatest resistance absorption, but also higher diffusion. Hydro pliolite found adequate from point view reducing accumulation most recommended for hydrated lime-based renders.
