What Mist coat?

Mist coats, often referred to as mist coats or primer coats, are a type of paint application used in the initial stages of painting new plaster. They are typically a diluted mixture of paint and water or a specialized primer designed to seal the porous surface of fresh plaster, allowing for better adhesion of subsequent paint layers. The mist coat helps to prevent issues like flaking or uneven coverage, ensuring a smoother finish once the final coats are applied.
