Answer: a water-based paint in several layers.

The generally accepted problem with paint on concrete is that it does not hold well and cracks very quickly. First, clean the old concrete wall, for example with liquid sodium hydroxide solution, and remove all traces of the old paint, especially if it is not uniform. It is important not to ignore the undercoat, it would give a catastrophic result in a few weeks, especially if it is a water feature. Concrete is a porous material, so it is better to use a water-based paint, in several layers, to repaint this type of surface. The water-based paint will penetrate the concrete better and ensure a lasting result. video id = "0" / Our practical DIY videos
