The presence of pinholes in concrete flooring is often an indication of an industrial floor coatings failure. When the concrete surface is applied with a film of coatings, air is trapped between the surface and the coating. A chemical reaction to warm temperature causes trapped air to rise to the surface and force its way out, creating crater-like surface indentations or pinholes.
Furthermore, when liquid industrial floor coatings settle into the concrete’s minute nooks and vents, air is displaced from these nooks and travel to nearby areas. When the displaced air has gathered enough force, it will eventually cause a mini-eruption to form pinholes. Continue reading ‘Concrete Coatings – Avoid Getting Pin-Holed’ »
