Oil-based paint once ruled the world of interior paint and coatings, particularly in high-impact areas such as trim work , doors , and cabinets. Yet with the nearly total phase-out of oil-based paint in the U. If a house is old enough, it is inevitable that it will have oil-based paint somewhere; latex paint wasn't introduced until the s. And newer houses might have oil-based paint, as it is not entirely banned. It is still available in quart sizes or smaller, and many professional painters favor oil over latex for a smoother, rock-hard finish. As long as the surface is fully cured, there is nothing inherent in the oiled-based paint coating that precludes an additional layer of latex paint.

Latex Primer Not Sticking to Walls and Paint Showing Through | ThriftyFun
A coat of primer is recommended for almost all painting projects, whether it's new drywall, old wood, bare metal, previously painted brick, or any other surface. Primer is essentially sticky, flat paint that is designed to adhere well and to provide a consistent base for topcoats of paint. If you paint a surface without priming it first, you will likely need more coats for adequate coverage, and the paint may not stick as well to the original surface as it would to the primer. There are different formulations of primer intended for different surfaces. Applying primer over new surfaces seals the original material so that the paint doesn't soak into it, requiring extra coats. Primer also helps to hide joints, or seams, on new drywall, and it prevents bleed-through from knots and other natural blemishes and coloring in bare wood.
Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted. Primer is a paint product that allows finishing paint to adhere much better than if it were used alone. Compared to paint, a primer is not intended to be used as the outermost durable finish and can instead be engineered to have improved filling and binding properties with the material underneath.
I am using a latex gray primer over red paint and having many problems. The primer is not sticking to my walls and I can still see the red paint. What can I do? Ad By Linda from NC.
