Yes, masonry paint can be used over an undercoat, but it's important to ensure that the undercoat is compatible with the masonry paint. The undercoat should be fully dry and properly prepared to ensure good adhesion and durability. Additionally, check the manufacturer's guidelines for any specific recommendations regarding the use of undercoat with masonry paint.
Yes, it should be. The required undercoat/primer is available in Home Depot,less than $20 last time I used it.
The best undercoat for a concrete wall is typically an acrylic latex primer. This type of primer adheres well to the porous surface of the concrete, helps to seal it, and promotes better paint adhesion. For areas with high moisture or potential efflorescence, a specialized masonry primer can be used to prevent moisture issues. Always ensure the surface is clean and dry before applying the undercoat for optimal results.

It is very easy to coat enamel paints with acrylic paints but you really should pay attention to a couple of points if you want it to be successful. Always sand the the enamal well and fill any holes with lindeed putty then apply a good coat of undercoat. I use an oil based undercoat first and then several days later sand the undercoat lightly and coat with acrylic all purpose undercoat. Once you have done this you can apply acrylic top coats. If you are using a self priming type acrylic paint on external work, you could skip the acrylic undercoat and apply it straight on to the oil based undercoat but you must leave it for several days to dry completely before coating with acrylic. I have used both methods over the past 5 years and both have not shown any sign of problems to date.
It's for painting concrete or brick.
Masonry putty is used to fill gaps, cracks, and imperfections in masonry surfaces, providing a smooth finish and enhancing the appearance of walls and structures. It helps to seal joints and prevent moisture penetration, which can lead to damage over time. Additionally, masonry putty can improve the adhesion of paint or other coatings applied to the surface, ensuring better durability and longevity. Overall, it serves both aesthetic and protective functions in masonry work.
It can be used on concrete or many of the modern fake concrete boards like Hardibacker.
I believe that you prime than paint than seal. It depends on the paint you are using and what you are painting A lot of the exterior paints used today don't require any undercoat. However if you are painting over a previously painted surface you must keep preparation in mind.

no it will peel. must use water base with water base & oil base with oil base.and use an undercoat to hide stains.
Stucco is typically considered a type of masonry. It is a cement-based material applied in layers over a solid substrate, such as concrete or masonry, and is often used for exterior finishes. While it can be applied over a frame structure, the stucco itself is not classified as a frame material.
For masonry wall surfaces, it is best to use a high-quality acrylic latex paint designed specifically for masonry. These paints offer excellent adhesion, flexibility, and resistance to moisture, helping to prevent peeling and damage. Additionally, masonry-specific paints often contain additives that inhibit mold and mildew growth, making them ideal for both interior and exterior applications. Always ensure the surface is clean and properly primed before painting for optimal results.
