Self Prime Technology

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.

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.

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.
