Self Prime Technology
When are primers traditionally required before the application of paint, and why?
- When painting an unpainted surface, to penetrate and seal the surface.
- When painting over dirty, scuffed and stained painted surfaces, to block the stains from showing through to the paint.
- When painting over bright or bold paint colours, to ensure the true colour of the finish coat isn’t affected by an undertone.
- When painting over glossy or hard surfaces, to ensure adhesion.
- When painting over problem surfaces, like metal, chalky concrete, knots in wood, etc.
How are primers formulated differently from conventional paints?
- Standard concrete primers are formulated to be more penetrating than paints, and contain a number of filler pigments to help them provide white-hide, but not durability.
- Specialty acrylic primers use 100% acrylic resins and high levels of TiO2 pigment to ensure increased adhesion and hiding power, as well as the ability to block stains.
- Specialty solvent-based primers vary by purpose. Some contain shellac to seal knots and harsh stains in wood, others contain anti-rust agents to properly prime metals, while others are designed to seal down chalking surfaces.
- No primer is a substitute for proper preparation such as washing, sanding and surface repair.
Ulttima Plus emulsion paints are said to contain Selfprime Technology because:
- They use 100% acrylic, super-adherent resins.
- The resins are cross-linked with zinc oxide to create a harder film that grips more tightly to the surface.
- They have very high levels of TiO2 and other pigments, and use very strong colorants, so that they will block out old colours and stains underneath them.
- They can be effectively be used as a “paint and primer in one” because they will work: Directly on properly-cured bare concrete; Directly over dry and sap-free new wood; Directly over previously painted or stained surfaces; Directly over Aluminium or Galvanized Metal.
