Contractors need to minimalize the time it takes to complete a project. Using a premium quality primer will ultimately make any job easier. Painting a light colour over a dark colour normally requires many coats of paint to achieve the appropriate coverage. Zinsser Bulls Eye 1-2-3 is a pre-tinted grey primer, which will reduce the number of coats needed for a flawless finish. As a rule of thumb, always use a grey tinted primer before painting with rich deep colours. It will enhance the colour, help to hide wall imperfections and ultimately will be less topcoats to achieve the desired colour. Zinsser Primers by Rust-Oleum will get the job done the first time.
