After Sandblasting Your Walls, What Type of Paint Should You Use?

At Blastrite, we specialise in providing you with the means to sandblast a variety of surfaces, ready for painting. By ensuring you’ve properly prepared your surfaces for painting, you can ensure that you maximise the durability and longevity of the paint, you’re left with an aesthetically pleasing surface, you seal in any surface stains and your paint is uniformly absorbed. You’ll also save both money and time by properly preparing your surfaces before you paint them.

But now you’ve prepared your surfaces, do you know which paint will work best for your surface? Paints come as either pigmented liquids or powders used to protect or aesthetically improve surfaces. You may be applying them with spray systems, brushes or rollers but choosing the right paint is the most essential decision at this point. Our guide should help you make the right choice.

Industrial paints

In terms of chemistry, there are huge variations between different types of industrial paint, depending on the surface you’re going to paint. Common types of industrial paint include:

  • Acrylic- Suitable for bonding metal, glass, ferrite, oily surfaces and plastics, acrylic is a synthetic resin used in high-performance water or latex-based paints.
  • Polyester- Used for marine applications, polyester is typically unsaturated.
  • Epoxy- Much more resistant to environmental degradation than resins such as alkyds, epoxy is used almost exclusively in aircraft components.
  • Inorganic/silicate- Uses titanium dioxide as an extender pigment
  • Polyurethane- these typically include a rubber-like, tough elastomer based on the condensation of organic isocyanates.
  • Polytetrafluoroethylene (PTFE)-  Paints belonging to this family of engineering plastics is characterised by a high thermal stability and virtually universal chemical resistance.

Features of industrial paints

Industrial paints have a variety of special features not found in domestic paints, including:

  • Anti-static properties
  • Heat resistance
  • Fire retardant
  • Waterproof
  • Water repellent
  • Rust preventive
  • Suitability for interior or exterior use
  • Has the ability to withstand high temperatures
  • Electro-resistive, including both non conductive and conductive materials
  • Elastomeric, making it suitable for substrates that are regularly stretched before being returned to their original dimensions.

Industrial paints come in a wide variety of colours, including, black, white, grey, blue, red and more. You should also be able to get hold of primers and finishes such as flat, satin, semi-gloss and high gloss. Many industrial paints will allow you a choice over the amount of coverage and specific gravity. VOC content, which is government regulated, will vary, along with pot life and viscosity. All of these things will ensure you choose the right industrial paint for your needs.
