For use with lime-based paints, this ecological PRIMA undercoat is formulated to consolidate the substrate and even out its absorption capacity, giving it good “blocking” capacity without interfering with its breathability. Helps prevent visible lines between painted areas by slowing down drying at the edges. 93% natural ingredients, VOC FREE (less than 0.20gr/l.) Form: Liquid, transparent Use: Interior & exterior PRIMA Eco Undercoat can be used to: -reinforce inconsistent substrates, consolidate potentially flaky or powdery substrates and ensure correct adhesion of the top layers. -even out slight differences in substrate absorption: in the case of pre-mixed plasters or mortars of similar composition to the original plaster. -reduce substrate absorption: limit the absorption of highly absorbent plasters by preventing the finish from drying too quickly in warm weather and reducing the risk of visible paint lines. Surfaces -Plaster, drywall, lime-based and clay-based substrates. -Vegetal resin-based paints and coatings -Sanded down synthetic products (water-repellent paints, high-gloss coatings or decorative paints) -Mortar-filled substrates -Low-absorbency substrates (compact and synthetic plasters, renders & coatings) Finish: Matte Level of difficulty: Easy Features: -Penetrates easily without forming a film -Highly breathable Tools: Synthetic brush or roller. Cleaning with soap and water. CoverageApproximately 90-110 ft²/l (≈8-10 m²/l) after dilution for 1 coat (for applications on smooth, normal absorbency surfaces.) Made In Italy
