Repaint masonry window sill

Question

Our house has a Victorian bay window and what appears to be chunky masonry/concrete window sills. They look like they are painted with some form of gloss which has become flaky and green over the years.

I want to repaint it and after either stripping or sanding I want to know what paint to use. I was going to buy some good quality masonry paint to use to paint the walls of our house (combination of brick/render) and wonder if I can use the same paint on the windows sills?

But masonry paint sometimes looks thinner than gloss paint and I wondered if should I buy some proper masonry gloss paint (if that exists?)

Thanks.

Answer 1

Acrylic/Latex: Because concrete is porous, a water-based or acrylic primer is more likely to soak into the concrete than an oil-based primer, bonding to the substrate and allowing the paint to grip the surface. These primers will also reduce the dust on interior concrete.

Answer 2

Yes this paint is out there go to a masonry supply they will hook you right up it will be oil base so get the proper cleaning agent for your brushes and rollers.
