Professional paint brush 170 x 70 mm. Brush for painting with acrylic dispersion paints, primers, and undercoats. Practical tips: Prepare the brush before first use by rinsing the bristles in hot water. Lightly dampen it before painting to improve paint absorption. To properly apply the paint or primer into the structure of the substrate, scoop generously, but no more than 1/3 of the bristle length. The brush is recommended for priming on fresh mineral substrates (e.g., lime-cement plaster) and all types of textured plasters with a texture up to 3 mm. Very good paint absorption capacity - well-suited for painting facades and interiors where the substrate consists of mineral cement-lime plaster (applies to paints) - effectively reaches the structure of the substrate and produces thick layers (applies to primers) - practical for application - the bristles do not clump with primers and low-viscosity paints. - Recommended for painting with paints where high aesthetics of the paint layer is not required. - Drips during painting. - Long tool lifespan. - Leaves very visible and unsightly brush stroke marks on very smooth surfaces (applies to paints).
