Emulsion paints are excellent for interior walls and ceilings.They employ water as solvent, are without fungicides and siccatives and possess high vapour permeability. They usually produce a matt surface and are best used on wood and wood sheeting. When painting plaster and concrete, faking can occur. Painting wet-on-wet avoids stains.The paints should be applied directly after preparation.
